Engineered Flooring Quality Control Program Quality control procedures are applied throughout the entire manufacturing process. The following is an outline of the quality control tests, measurements and other procedures. Lumber Receiving: Lumber shipments are received into the factory and inspected for acceptance.

• Visual inspection of overall quality of lumber: overall appearance and quality, defects, checking, stain.

Frequency: each shipment received.

• Comparison with purchase order specifications: specie, grade, length, width. Frequency: each shipment received.

• Moisture content testing. Frequency: each shipment received. Specifications: MC acceptable range = 6-9%, if the lumber is within this range it is cleared for processing. If the moisture content is not within the range, then the lumber is removed from production and conditioned to the acceptable range of moisture content.

Tools and methods: A moisture meter is used to verify moisture content, if outside of the acceptable range, then the oven dry moisture content testing procedure and equipment are applied.

Lumber processing: As lumber is processed, each individual board is visually inspected to determine the best yield possible. Each board is cut to size, surfaced, and defected per grading rules of the flooring. Veneer blanks are the process output.

• Visual inspection of quality of rough lumber Frequency: continuous, every board is inspected, 100%

• Dimension measurement of length, width and thickness Frequency: beginning of a production run and 1 time/hour of production. Tools and methods: micrometers are used to physically measure the width and thickness of lumber blanks after ripping trimming and surfacing. Specifications: internal specifications for target thickness, length, and width.

Lumber Receiving and Processing

The lumber blanks are again visually inspected and then stacked by grade and size, ready to process into wear layers.

When lumber is received, it is inspected visually for compliance in width, length, grade and overall appearance compared to the purchase order specifications. Moisture content verification: samples are cut randomly from each unit of lumber and the moisture content is determined by the oven dry method. If the moisture content is within an acceptable range 6-9%, the unit proceeds to be processed.

As the lumber is processed each individual board is visually inspected prior to processing. The lumber is then ripped, trimmed, and surfaced to desired size. Defects are cut from the boards.


Cook, MN 55723 800-788-9689

Veneer Wear Layer Production Ashawa Bay floors manufactures hardwood veneer wear layers using framesaw technology to achieve high yields and accurate thickness of the wear layers. The sawn veneers have a desirable look of a sawn plank and not the “plywood” look of rotary produced veneer products. The wear layers are sanded to tight tolerances and sorted per grade prior to entering flooring production.

Prepped lumber blanks are loaded into the infeed of the the framesaws for processing into veneer wear layers.

Veneer wear layers exit the framesaw, ready to sand to thickness tolerance.

Veneer wear layers are inspected for quality, grade, and measured for thickness before being stacked for flooring production.


Cook, MN 55723 800-788-9689

Engineered Flooring Production Ashawa Bay engineered flooring is produced using state of the art equipment along with tight quality control measures that results in a high quality flooring product.

After laminating, each flooring plank is sanded to tight tolerances.

Flooring planks flow through the machining process where the edges are machined with the tongue and groove, and the ends are trimmed square and end matched with a tongue and groove.

Through each stage of the process the flooring width and thickness are measured with very precise calipers to make sure the product is being made to final tolerances.


Cook, MN 55723 800-788-9689

Engineered Flooring Packaging - Unfinished

Ashawa Bay engineered floors are packaged after production and prepared for shipping. The flooring is bundled per internal specifications of the proper number of pieces and square footage per package. The bundles are then end capped for protection from shipping damage, and then shrink wrapped in plastic to protect the flooring from moisture. The shrink wrapped bundles are then palletized for shipment.

Bundles of flooring are end capped with cardboard for damage prevention.

The flooring bundles are shrink wrapped in plastic and labeled.

The wrapped bundles are palletized, edge protected, banded, and stretch wrapped in plastic for shipping.


Cook, MN 55723 800-788-9689

Plywood Information and Processing Ashawa Bay floors uses only structural rated Baltic Birch plywood in the construction of our engineered flooring. Baltic Birch is recognized as the premium plywood substrate in engineered flooring due to the strength properties, lack of voids, exterior rated adhesive, and dimensional stability. The plywood suppliers produce the plywood to GOST standards and it is CARB compliant. We test the plywood for moisture content when it arrives at our factory and before we process it.

Baltic Birch plywood arrives into our factory packaged in crates.

Each individual sheet of plywood is sanded to exact thickness tolerance prior to use in flooring manufacture.

Each sheet of plywood is scored with grooves along the back side to relieve any internal stresses that may exist and allow the flooring to lay flat.


Cook, MN 55723 800-788-9689

Plywood Internal Bond Testing The internal bond (IB) test is a tensile test which a sample is loaded into a tensile test machine and it is pulled apart. The resulting information is the number of pounds per square inch are required to pull the sample apart. We use this test method when analyzing plywood options for use as substrate in the construction of engineered flooring. When compared to other plywood options used in the engineered flooring industry, Baltic Birch plywood greatly out performs the others in IB strength. This is important since it measures the amount of stress a substrate can withstand prior to failure. The higher the IB strength, the lower the chance of substrate failure.

This control chart illustrates typical IB values for Baltic Birch plywood substrate. The average is 278 pounds/square inch.

The average IB values for comparison of substrates: China hardwood import = 127 Aspen USA = 140 Baltic Birch = 278

Oven Dry Method for Determining the Moisture Content of Wood

The oven-dry method is the most accurate and reliable method of determining the moisture content (MC) of wood at any moisture content. Because of this accuracy and reliability, the oven-dry method is the method against which all other methods are judged. The MC of lumber and wood products is expressed as the ratio of the amount of water in a piece of wood compared to the oven-dry weight of the wood. This is called the “moisture content on the oven-dry basis”. For lumber and most wood products, MC is expressed in percent so the ratio is multiplied by 100. Amount of water in the wood %MC = --------------------------------------- x 100 Oven-dry weight of wood The amount of water in the wood is the difference between the original weight and the oven-dry weight. (Original weight – Oven-dry weight) %MC = ---------------------------------------------- x 100 (Oven-dry weight) The original weight is the weight of the sample of unknown MC. The oven-dry weight is the weight of the sample after all the water is removed. OVEN DRYING MOISTURE SECTIONS Samples are cut from the wood product to be tested, numbered, and immediately weighed on a scale that is accurate to the 0.01 gram. The weight is recorded for each sample. An electric oven with an internal fan is used for drying the samples. The oven is pre-heated to 215-217 degrees F. The samples are placed into the oven and dried for 18 to 24 hours. A few samples are then removed and weighed, placed back into the oven for another 2 hours. The samples are then weighed again to see if they are dry or still losing weight. If they are dry, the samples are then weighed on the scale. The weights are recorded and the %MC is calculated using the above formula. (Please see the “Guide for Using the Oven-Dry Method for Determining the Moisture Content of Wood” from the University of Wisconsin-Madison for more details.)

Oven dry method oven and scale.

The electric drying oven has an internal fan for circulating air which dries the wood samples thoroughly. The oven is operated at 215-217 degrees F during the drying cycle.

The scale is used to weigh the wood samples before and after drying. It is accurate to 0.01 grams, which provides for a very accurate calculation of moisture content.

Bond Line Test Procedure ANSI/HPVA EF 2009

Two test specimens, 50.8 (2 inches) wide by 127 mm (5 inches) along the grain, shall be cut from each flooring sample tested. The specimens shall be cut from opposite sides of the flooring after the tongue and groove portions have been removed. The specimens shall be submerged in water at 24 degrees C +/- 3 degrees (75 degrees F +/- 5 degrees) for 4 hours, then dried at a temperature between 49 and 52 degrees C (120 and 125 degrees F) for 19 hours, with sufficient air circulation to lower the moisture content (based on oven-dry weight) of the specimens to a maximum of 8 percent. This cycle shall be repeated until all specimens fail or until three cycles have been completed, whichever comes first. The flooring shall be considered as failing when any single delamination between two plies of either specimen is greater than 50.8 mm (2 inches) in continuous length, over 6.4 mm (1/4 inch) in depth at any point, and 0.08 mm (0.003 inch) in width as determined by a feeler gauge 0.08 mm (0.003 inch) thick and 12.7 mm (1/2 inch) wide. Specimens shall be examined for delamination at the end of each cycle. Delamination due to tape at joints of inner plies or defects allowed by grade shall be disregarded. For performing the bond line test, flooring samples shall be selected in multiples of ten in order to provide for a sufficient number of specimens (two specimens per sample) to which acceptance levels are applied. Ninety-five percent of test specimens shall pass the first cycle, and eighty-five percent of test specimens shall pass the third cycle.

Equilibrium Moisture Content (EMC) of Wood For any given combination of relative humidity and temperature conditions, there is an equilibrium moisture content (EMC) of wood. Wood products, such as engineered wood flooring, are manufactured to an EMC which is the result of “normal” household conditions of temperature and humidity. The EMC range for flooring manufacture is 6-9%. The temperature and relative humidity range to maintain this EMC is 60-80 degrees F and 35-50% relative humidity. This range is the “comfort zone” for wood flooring. Fluctuations from this range will result in a change of EMC in the wood flooring which can cause problems with shrinkage, swelling, checking, cracking, warping, cupping, and distortion from flatness. The chart below illustrates the EMC for given temperature and relative humidity conditions. Relative Humidity % Temp F

Flooring Bond Line Chisel Test

The bond line between the hardwood veneer wear layer and the plywood substrate is tested regularly using the chisel test method. This method was developed by manufacturers in conjunction with adhesive suppliers as a way to test the bond line quickly and easily determine a pass or fail of the bond. The test is performed immediately after the laminating process and is a reliable indicator of an acceptable bond.

A sample is cut from a engineered flooring blank immediately after existing the laminating press. A chisel is placed on the bond line and tapped on with a hammer.

The chisel is tapped until the sample splits open.

The split sample is inspected to see where the failure occurred. If the glue bond is acceptable, then the split will occur within the wood fiber of the plywood and veneer (as indicated in the photo). If the bond is split on the glue line with no wood fiber present, then the bond fails the test.

Flooring Tongue and Groove Fit Test A field fit test has been developed but the flooring industry to determine the proper tightness of the tongue and groove. This test is used to get a quick determination of the tongue and groove fit. If the fit is not acceptable, then precise measurements are taken and adjustments are made. Random samples (2 pieces of flooring) are taken off of the production line and put together so the edges are tight together. The pieces are then held up by the top piece to see if the bottom piece stays connected. If it stays connected, then the pieces are gently shaken until the bottom piece comes free. If the piece does not easily shake free, then the fit is too tight. If the piece falls freely without any shaking, the fit is too loose. If the bottom piece separates from the top piece with a few gentle shakes, then the fit is acceptable.

2 pieces of flooring are assembled so the edges are tight together. The assembled pieces are held by the top piece only.

The 2 pieces begin to separate with a gentle shaking motion.

The bottom piece has fallen away after a few gentle shakes.


Cook, MN 55723 800-788-9689

Tongue and Groove Fit Test – Go/No Go Gauges The tongue and groove of the flooring is fit tested regularly using a gauge that is made from machined metal to an exact size. The gauge is placed into the groove and over the tongue to measure the size of the tongue and groove compared to the gauge. If the gauge fits snuggly over the tongue and into the groove, this is considered a “go” situation and the sizes are correct and no adjustments are required. If the gauge is loosely fitting or will not fit at all, then this is a “no go” situation and adjustments are made to the machinery.

The Go/No Go gauge is a metal template made to exact tolerances to match our machine tooling and therefore the tongue and groove of our flooring.

The gauge is placed into the groove to verify the proper fit and size of the groove.

The gauge is placed over the tongue to verify the proper size and fit of the tongue.


Cook, MN 55723 800-788-9689

Machine Tooling for Flooring Tongue and Groove The tooling that we use on our molder and end matcher machine the tongue and groove around the perimeter of every flooring plank. There are several important factors when considering the type of tooling used on the machinery. The highest quality, longest lasting tooling that produces the most accurate machining and the most repeatable results is diamond tipped tooling that is precision ground. Ashawa Bay flooring is made with this type of tooling. Each time we change tooling we know that we can produce the same exact size of tongue and groove that we have in the past. This is important so flooring from any manufacturing run will fit perfectly together with flooring from past production or future production. The diamond tips keep the tooling sharp for an extended period of time due to reduced wear compared to other types of tooling. This results in the same size tongue and groove being produced every time. We have computer drawings of our tooling with exact measurements so that any future tooling can be made by computer controlled CNC machines and duplicate the profiles to exact tolerances. (See computer drawing of tooling on following page). Our commitment to use only the best tooling available results in a high quality product from every production run and reduced product variability.

Ashawa Bay engineered floors warranted for

installation over radiant in-floor heating systems

Ashawa Bay engineered floors are warranted for installation over radiant in-floor heating system. Our standard limited lifetime structural and finish warranty applies to installations over radiant in-floor heating systems. Our floors are built to stand up to generations of use, and should age beautifully with minimal care. We pride ourselves in applying continuous and rigorous quality control and back our floors with a lifetime warranty against manufacturing defects and on the pre-finished with a 25 year finish warranty in residential applications and a 5 year finish warranty in commercial applications. Please see our full warranty for complete details. As with any flooring installation, care is advised in radiant in-floor applications due to the potential for overheating of the in-floor heat system. It is also very important that the heat be increased gradually to avoid shocking the floor. For Radiant In-Floor Heat Applications, installation/operation must meet or exceed the following requirements:

1. Prior to installation the heating system should be operated at 60% of maximum output for at least 2 weeks for complete moisture stabilization. About 3 days prior to installation, reduce the heating system to a suitable temperature of about 18 C or 64 F.

2. About 2 days after installation gradually over a period of 10 days increase the temperature to comfortable operating level.

3. During the operation of the in-floor heat system, the temperature of the floor MUST NOT EXCEED 81 degrees F/27 degrees C. Exceeding this temperature will void your floor’s warranty.

4. As with any wood floor, the floor will perform best if humidity is maintained between 35%-50%. Use a humidification system as needed.

Please refer to the NWFA flooring installation guidelines for complete best practices to ensure your Ashawa Bay engineered floor will give a lifetime of use.

STAPLE OR NAIL DOWN APPLICATION INSTALLATION INSTRUCTIONS

PRIOR TO INSTALLATION: Inspect all materials carefully before installation. Warranties do not cover materials with visible defects once they are installed. It is the responsibil ity of the installer/owner to determine if the jobsite conditions are environmentally acceptable and that the sub-floor system is acceptable for the installation of wood flooring. Ashawa Bay Hardwood Floors declines any responsibil ity for wood floor failures or problems associated with or resulting from sub-floor/sub-surface structural or environmental deficiencies or jobsite damage after the hardwood flooring has been installed. The following instructions comply with all recommendations as outlined in Installation Guidelines and Methods published by the National Wood Flooring Association (NWFA). For additional information contact NWFA at www.NWFA.org. NOTE: Ashawa Bay Hardwood Floors recommends the following fasteners and schedules for installing by staple or nail down application. Staples: 3/8” or narrower crown x 1.25” ‒ 1.5” fasteners, 1-3” from ends, every 3-4” intervals, installed at a 45 degree angle. Nails: 6d finish nails, or 1.25”-1.5” cleats, 2 fasteners 1-3” from each end, every 4-6” intervals, installed at a 45 degree angle.

I . SITE CONDITIONS : Wood is hydroscopic and will absorb or expel moisture based on environmental conditions. Gain and loss of moisture corresponds with an increase or decrease in size and occasional warping. Ashawa Bay Flooring is 100% hardwood and is more dimensionally stable due to the multi-ply construction but it is not immune to these dimensional changes. For the best results we recommend that Ashawa Bay Flooring be stored in the controlled environment in which it will be installed for 5-7 days prior to installation.

A. The building should be closed in with all outside doors and windows in place. The wall coverings should be in place and the painting completed except for the final coat on the base molding. If possible, delay installation of base molding until flooring installation is complete. All concrete, masonry, framing members, drywall, paint and other “wet” work should be thoroughly dry. Basements and crawl spaces must be dry and well ventilated. B. Surface drainage should direct water away from the building. C. Crawl spaces must be a minimum of 18” (46 cm) from the ground to underside of joists. A ground cover of 6-20 mil black polyethylene film should be installed as a vapor barrier with joints lapped and sealed with moisture resistant tape. The crawl space should have perimeter venting equal to a minimum of 1.5 square feet per 100 square feet of the crawl space and allowing for cross ventilation. Note: Local building codes may differ. D. Ashawa Bay Flooring may be installed below, on or above grade level. Ashawa Bay Flooring is not recommended for applications in areas where excessive humidity is present such as full baths, hot tub enclosures or wine cellars. E. Permanent air conditioning and heating systems should be in place and operational. The installation site should have a consistent room temperature of 60-80°F (16-27°C) and humidity of 35-50% for 14 days prior, during and after installation. F. Radiant Heat Applications must meet or exceed all of the requirements in section II and:

1. Before installation: The heating system should then be run at 2/3 of maximum output for a minimum of 2 weeks to allow any remaining moisture to evaporate, attaining its final moisture

content without causing damage. Three or four days before installation, the heating system must be reduced to a suitable temperature (about 18c/64f). 2. After Installation: Approximately 2 days after installation is complete, gradually (over a period of 1 week) raise the temperature of the heating system to its desired operating level. 3. Life Cycle: Surface Temperature of flooring should never exceed 81 degrees F/27 degrees C. Exceeding this temperature will void any related warranty by the flooring manufacturer. Most under-floor heating systems DO NOT have a humidification system. Add humidification as necessary to maintain humidity levels between 35-50%.

I I. SUB-FLOOR REQUIREMENTS : The following minimum standards must be met before beginning the application of any Ashawa Bay Flooring products. The sub-floor must meet the following minimum requirements. See additional requirements specific to the installation method.

A. LEVEL/FLAT - within 3/16” in 10’ and/or 1/8” in 6’. B. CLEAN ‒ Free of debris, loose materials or materials that may release with age such as paint and dry wall materials. C. DRY - Check and document moisture content of the sub-floor using the appropriate moisture test. Concrete sub-floors must be a minimum of 30 days old before testing begins. Concrete must not exceed 4.5 using a Tramex Moisture Encounter meter. Calcium Chloride test results should not exceed 3# 24hr/1000 ft2. Wood sub-floors must not exceed 12% and there must be no more than 4% difference between the Ashawa Bay Flooring and the wood sub-flooring material. D. STRUCTURALLY SOUND ‒ The attachment methods used for the installation of Ashawa Bay Flooring ARE NOT designed to stiffen existing sub-floors. If the sub-floor has excessive deflection before installation of the flooring it is unlikely to improve with the addition of Ashawa Bay Flooring. Excessive deflection may cause premature finish wear and the floor to become noisy with age.

1. Wood sub-floors : Wood panels should have an adequate fastening pattern, glued and /screwed or nailed as system requires

using the acceptable fastener and pattern. Typical: 6” (15 cm) along bearing edges and 12” (31 cm) along intermediate supports. Flatten any swollen or raised edges as necessary by sanding or scraping. Nail or screw any areas that are loose or squeak. Replace any water damaged swollen or delaminated sub-flooring or underlayment. Best results occur when the sub-floor has a minimum thickness of 3/4”. 2. Concrete sub-floors : Concrete must have a minimum compressive strength of 3000 PSI. The concrete must be free from sealers, waxes, oil, paint, drywall compound, etc. that will interfere with adhesive bonding. Do not attempt to glue a wood floor over a chalky or soft concrete slab.

I I I . STAPLE/NAIL DOWN INSTALLATION of Ashawa Bay Flooring: Ashawa Bay Flooring can be installed over most structurally sound sub-floors provided it is wood or wood composite board (plywood, OSB).

A. PREPARATION AND LAYOUT: 1. Inspect all door casings and wall molding. Where necessary cut the moldings to allow the wood flooring to slide beneath them. This can be done with a jamb saw or by placing a piece of flooring (face down) next to the molding. Using a carpenter’s saw laying flat on the flooring saw through the casing. Remove the waste material and sweep away all debris. 2. Plan the layout for the best visual appearance of the finished wood floor. Measurements must be made to allow for the width of the flooring plus 1/2” expansion space and must allow for the width of the tongue. 3. Place a mark approximately 18” from the corners of the starting wall and the width of the flooring plus 5/8” to allow for expansion and the tongue. Example: When installing 3” flooring place the mark approximately 18” from each end wall and 3-5/8” from the starting wall. Strike a chalk line through these two points the

length of the room to the end walls. This line is the WORKING LINE.

B. INSTALLATION: 1. Measure the distance between the WORKING LINE and the wall the full length of the starting wall. If the wall is badly out of line (crooked) it may be necessary to rip boards to the follow the irregularity in the wall. 2. Using face nailing install a sacrificial row on the INSIDE edge (closest to the wall) of the chalk line. This row may be of any straight wood material or the narrowest width of flooring. Install with the groove side facing the wall. Make certain each of the sacrificial boards is in perfect alignment with the WORKING LINE. When satisfied, attach the board to the sub-floor using finish nails or concrete nails. This sacrificial row is to minimize movement of the flooring during installation and will be removed once the floor installation is complete. 3. Install the first board making certain that the groove side is tight against the sacrificial board. Installation can be from the left or right. “Blind” nail or staple using the recommended schedule and fastener. 4. Insert the end of the next board into the adjoining tongue or groove and force the board tightly against the sacrificial board and the end of the adjoining first board and continue fastening per schedule. 5. After three or more boards have been installed in the first row installation of the second row can began. 6. Select a board for the second row that will allow at least 6” of difference between it and the length of the board in the first row. Continue installing in this manner until three or more boards have been installed. Continue adding rows, blind nailing the tongue side. Avoid close alignment of joints in all rows throughout the installation, always attempting to get the maximum spacing available with a minimum of 6”. Avoid alignment of joints in opposite rows, which may create an “H” pattern in the floor. 7. Cut to length a board that fits at the end of each row always allowing for 1/2" expansion space at the wall. TIP: Do not cut short

boards to finish a row. The leftover materials will be used for future starter boards. Short lengths cannot be used and will become waste. 8. Measure the final row. Rip the boards (parallel cut) to fit the final wall allowing for ½” expansion. Use finish nails through the face to secure the final row in place. 9. Remove the sacrificial row being careful to not damage the adjoining boards. If 1/2" expansion is not available because of a bow in the wall rip the boards to allow the required spacing. Using finish nails face nail the final row into place.

C. COMPLETING THE JOB: 1. Inspect for gaps, chips and touch up or fill with the appropriate filler as necessary. Use colored latex filler for factory finished products and a stainable filler if the floor is to be sanded and finished. 2. Install/reinstall all moldings and clean the floor with the appropriate cleaner.

GLUE DOWN APPLICATION INSTALLATION INSTRUCTIONS

PRIOR TO INSTALLATION: Inspect all materials carefully before installation. Warranties do not cover materials with visible defects once they are installed. It is the responsibil ity of the installer/owner to determine if the jobsite conditions are environmentally acceptable and that the sub-floor system is acceptable for the installation of wood flooring. Ashawa Bay Hardwood Floors declines any responsibil ity for wood floor failures or problems associated with or resulting from sub-floor/sub-surface structural or environmental deficiencies or jobsite damage after the hardwood flooring has been installed.

The concrete must be free from sealers, waxes, oil, paint, drywall compound, etc. that will interfere with adhesive bonding. Do not attempt to glue a wood floor over a chalky or soft concrete slab.

I I I . GLUE-DOWN INSTALLATION of Ashawa Bay Flooring: Ashawa Bay Flooring can be installed over most structurally sound sub-floors or existing permanently bonded flooring materials. Wood, concrete, sheet vinyl, vinyl tile, ceramic, are all acceptable sub-floors provided they meet the standards outlined in section II.

A. PREPARATION AND LAYOUT: 1. Inspect all door casings and wall molding. Where necessary cut the moldings to allow the wood flooring to slide beneath them. This can be done with a jamb saw or by placing a piece of flooring (face down) next to the molding. Using a carpenter’s saw laying flat on the flooring saw through the casing. Remove the waste material and sweep away all debris. 2. Plan the layout for the best visual appearance of the finished wood floor. Measurements must be made to allow for the width of the flooring plus 1/2” expansion space and must allow for the width of the tongue. 3. Place a mark approximately 18” from the corners of the starting wall and the width of the flooring plus 5/8” to allow for expansion and the tongue. Example: When installing 3” flooring place the mark approximately 18” from each end wall and 3-5/8” from the

starting wall. Strike a chalk line through these two points the length of the room to the end walls. This line is the WORKING LINE.

B. INSTALLATION: 1. Measure the distance between the WORKING LINE and the wall the full length of the starting wall. If the wall is badly out of line (crooked) it may be necessary to rip boards to the follow the irregularity in the wall. 2. Using no adhesive install a sacrificial row on the INSIDE edge (closest to the wall) of the chalk line. This row may be of any straight wood material or the narrowest width of flooring. Install with the groove side facing the line (tongue towards wall). Make certain each of the sacrificial boards is in perfect alignment with the WORKING LINE. When satisfied, attach the board to the sub-floor using finish nails or concrete nails. This sacrificial row is to minimize movement of the flooring during installation and will be removed once the floor installation is complete. 3. Read the label on the adhesive container. Using the trowel recommended by the adhesive supplier spread an area that can be covered with wood within the working time of the adhesive (as noted on pail), generally 30-45 minutes. An average spread is an area 14-25” deep and the length of the room. 4. Install the first board making certain that the TONGUE side is tight against the sacrificial board. Installation can be from the left or right. 5. Insert the end of the next board into the adjoining tongue or groove and force the board tightly against the sacrificial board and the end of the adjoining first board. 6. After three or more boards have been installed in the first row installation of the second row can began. 7. Select a board for the second row that will allow at least 6” of difference between it and the length of the board in the first row. Continue installing in this manner until three or more boards have been installed. Continue adding rows, extending each as necessary until all of the adhesive has been covered. Avoid close alignment

of joints in all rows throughout the installation, always attempting to get the maximum spacing available with a minimum of 6”. Avoid alignment of joints in opposite rows, which may create an “H” pattern in the floor. 8. Cut to length a board that fits at the end of each row always allowing for 1/2" expansion space at the wall. TIP: Do not cut short boards to finish a row. The leftover materials will be used for future starter boards. Short lengths cannot be used and will become waste. 9. Once the first section has been completed inspect it closely, tightening all end and side gaps as necessary. Clean all adhesive from the surface immediately. DO NOT wait to clean the surface until completion of the job, as the adhesive may not be removable. If necessary use blue painter’s tape to hold the joints tightly together until the adhesive cures if necessary. DO NOT use masking tape as the adhesive residue may affect the factory finish or bond of the finish if the materials are unfinished. 10. Spread a new working area and proceed as above. Use the cut ends of the boards from the previous section as starter boards when possible. Avoid lengths shorter than 4” as they are hard to keep in alignment and are easily displaced. Continue in this manner until all rows are complete. 11. Measure the final row. Rip the boards (parallel cut) to fit the final wall allowing for ½” expansion. Use blue painter’s tape to hold the final row in place. 12. Remove the sacrificial row being careful to not damage the adjoining boards. If 1/2" expansion is not available because of a bow in the wall rip the boards to allow the required spacing. Apply adhesive to the back of each board and gently press in place. Pull the boards tightly to the previously installed row and hold in place with blue painter’s tape.

C. COMPLETING THE JOB: 1. Remove all tape from the floor starting from the area in which the

wood was first applied. Inspect for gaps, chips and adhesive residue while removing the tape. Remove all adhesive residue, touch up chipped areas and fill with the appropriate filler as necessary. Use colored latex filler for factory finished products and a stainable filler if the floor is to be sanded and finished. 2. Install/reinstall all moldings and clean the floor with the appropriate cleaner. Use a premium quality cleaner for urethane wood floors if the product is factory finished or the compatible cleaner (if required) if the floor is to be sanded and/or finished. 3. If required by the adhesive manufacturer roll the floor with the appropriate weight roller. 4. First use of the floor varies from one adhesive manufacturer to another. Generally the floor can have light foot traffic after the adhesive has cured for 18-24 hours with furniture being LIFTED into place after 24 hours. 5. If the flooring is UNFINISHED adequate curing time MUST be allowed prior to finishing of the floor. If the adhesive is a urethane or solvent based adhesive 72 hours is usually an adequate amount of time to achieve full-cure. DO NOT attempt to finish the floor before the adhesive has had an adequate period of time to cure and dissipate all solvents or moisture as the this will affect the final appearance and performance of the finish and floor.

FLOATING FLOOR APPLICATION INSTALLATION INSTRUCTIONS

PRIOR TO INSTALLATION: Inspect all materials carefully before installation. Warranties do not cover materials with visible defects once they are installed. It is the responsibil ity of the installer/owner to determine if the jobsite conditions are environmentally acceptable and that the sub-floor system is acceptable for the installation of wood flooring. Ashawa Bay Hardwood Floors declines any responsibil ity for wood floor failures or problems associated with or resulting from sub-floor/sub-surface structural or environmental deficiencies or jobsite damage after the hardwood flooring has been installed. The following instructions comply with all recommendations as outlined in Installation Guidelines and Methods published by the National Wood Flooring Association (NWFA). For additional information contact NWFA at www.NWFA.org. NOTE: Ashawa Bay Hardwood Floors recommends using a premium wood glue (PVA carpenters’ glue), such as Franklin Tite Bond II or equivalent, and a premium closed cell foam pad underlayment.

A. The building should be closed in with all outside doors and windows in

place. The wall coverings should be in place and the painting completed except for the final coat on the base molding. If possible, delay installation of base molding until flooring installation is complete. All concrete, masonry, framing members, drywall, paint and other “wet” work should be thoroughly dry. Basements and crawl spaces must be dry and well ventilated. B. Surface drainage should direct water away from the building. C. Crawl spaces must be a minimum of 18” (46 cm) from the ground to underside of joists. A ground cover of 6-20 mil black polyethylene film should be installed as a vapor barrier with joints lapped and sealed with moisture resistant tape. The crawl space should have perimeter venting equal to a minimum of 1.5 square feet per 100 square feet of the crawl space and allowing for cross ventilation. Note: Local building codes may differ. D. Ashawa Bay Flooring may be installed below, on or above grade level. Ashawa Bay Flooring is not recommended for applications in areas where excessive humidity is present such as full baths, hot tub enclosures or wine cellars. E. Permanent air conditioning and heating systems should be in place and operational. The installation site should have a consistent room temperature of 60-80°F (16-27°C) and humidity of 35-50% for 14 days prior, during and after installation. F. Radiant Heat Applications must meet or exceed all of the requirements in section II and:

A. LEVEL/FLAT - within 3/16” in 10’ and/or 1/8” in 6’. B. CLEAN ‒ Free of debris, loose materials or materials that may release with age such as paint and dry wall materials. C. DRY - Check and document moisture content of the sub-floor using the appropriate moisture test. Concrete sub-floors must be a minimum of 30 days old before testing begins. D . STRUCTURALLY SOUND:

1. Wood sub-floors: Wood panels should have an adequate fastening pattern, glued and /screwed or nailed as system requires using the acceptable fastener and pattern. Typical: 6” (15 cm) along bearing edges and 12” (31 cm) along intermediate supports. Flatten any raised edges as necessary by sanding or scraping. Nail or screw any areas that are loose or squeak. Replace any water damaged swollen or delaminated sub-flooring or underlayment. Best results occur when the sub-floor has a minimum thickness of ¾”.

2. Concrete sub-floors: Remove all loose or broken concrete and fill/flatten as necessary using cementitious leveling materials of 3000 PSI or more. When installing over concrete a 6-mil poly vapor barrier must be installed prior to the underlayment pad. All joints should be lapped 6” and sealed with a moisture resistant tape.

III. FLOATING INSTALLATION OF ASHAWA BAY FLOORING: Ashawa Bay Flooring can be installed over most structurally sound sub-floors or existing flooring materials. Wood, concrete, sheet vinyl, vinyl tile, ceramic, commercial carpet (use no underlayment) are all acceptable sub-floors provided they meet the standards outlined in section II.

NOTE: Avoid walking on the floor during installation as traffic may loosen or break glue joints. A. PREPARATION AND LAYOUT:

1. Inspect all door casings and wall molding. Where necessary cut the moldings to allow the wood flooring to slide beneath them. This can be done with a jamb saw or by placing a piece of flooring (face down) next to the molding. Using a carpenter’s saw laying flat on the flooring saw through the casing. Remove the waste material and sweep away all debris.

2. Plan the layout for the best visual appearance of the finished wood floor. Measurements must be made to allow for the width of the flooring plus 1/2” expansion space and must allow for the width of the tongue.

3. Measure across the room to identify how many ROWS of flooring will be needed. If the LAST row will require a cut board (rip) of less than 1-1/2” in width plan to adjust the floor by starting with a ripped board and account for the rip in the next measurement (step3).

4. If the sub-floor is concrete install a 6-mil poly vapor barrier. All joints should be lapped 6” and taped with a moisture resistant tape. DO NOT install this vapor barrier over wood sub-floors.

5. Install the underlayment parallel to the starting wall and in the same direction that the Ashawa Bay Flooring will be installed. Do not overlap joints. Underlayment should be cut flush with the walls. Tape all joints using a water resistant tape such as packing tape; allow no wrinkles. Tape the starting row to the floor to prevent movement.

6. Place a mark approximately 18” from the edge of the end walls and the width of the Ashawa Bay Flooring plus 5/8” to allow for expansion and the tongue. Example: When installing 3” wide flooring place the mark approximately 18” from each end wall and 3-5/8” from the starting wall. Strike a chalk line through these two points the length of the room to the end walls on top of the underlayment. This line is the WORKING LINE.

of 6

B. INSTALLATION: Option: Install a sacrificial board the full length of the floor on the inside edge of the WORKING LINE to form a support for the balance of the flooring installation. Proceed to step 1 using wedges to hold the flooring in place on the ENDS. 1. Select the longest boards available. Work from several cartons to maintain color uniformity. Lay the boards out the length of the room. Make certain that the first and final board in the row will be at least 12” in length. The last UNCUT board must allow at least 12” between the board end and the wall. If the board in the row will need to be cut less than 12” in length to complete the row adjust the board selection accordingly.

2. Begin installation from the RIGHT corner with the tongue facing you and the long GROOVE facing the starting wall or sacrificial row. The short end groove should be facing the end wall. Align the first board with the WORKING LINE.

3. Select the second board. Place a 1/8” continuous bead of glue in the inside bottom edge of the END groove. DO NOT apply glue to the long side groove at this time. Interlock the joint with the first board always maintaining alignment with the WORKING LINE. Remove any excess glue from the surface with a towel dampened in warm water. Use blue tape to temporarily hold the end joints together. Use wedges or waste material in the expansion gap on the side and end walls (ends only if sacrificial board was used) to maintain alignment with the WORKING LINE. Continue installing in this manner until the first row is complete.

4. Measure and cut to length the final board in the row allowing 1/2” expansion between the end of the board and the end wall. Select a longer board for this cut, as the material left over will be used as a starter board later. Do not use short boards that would allow waste of 3” or less as this cannot be used later. Apply glue in the groove and install as above. Set the waste end aside for later use.

5. Select a new set of materials just as in step 4. If the cut-off waste from the first row was 18” or longer it can be used as the first board in the row. Maintain a minimum of 6” spacing between the end joints of all rows.

6. Place a continuous bead of glue along the inside bottom edge of the END groove and the same location on the side groove. Carefully align the tongue and grooves together and tighten the plank until all joints are snug. Remove any excess glue as before and temporarily hold the joints together using blue tape. Cut and install the final board in the row as in step 7.

7. Continue in this manner until the first four rows are completed. This four-row area is the base for the balance of the floor installation. Perfect alignment is essential, as any variance will worsen as the flooring proceeds further into the room. Carefully inspect for proper alignment before the glue sets. Adjust as necessary.

8. Continue with the installation as above. Best appearance occurs with a minimum of 6” spacing between joints in adjacent rows and avoiding a pattern in the floor. Try to avoid aligning joints closer than four rows apart as this may eventually create a pattern. Continue using tape to hold the joints together and wedges to hold the end joints in place. DO NOT walk on the finished floor during installation, as this will break the uncured glue joint. DO NOT roll the floor for the same reason.

9. Finish the final row by cutting the boards to fit, always allowing 1/2” expansion space.

10. If a sacrificial row was used remove it and replace with a row of materials that is properly edge glued as above.

C. COMPLETING THE JOB:

1. Remove all tape from the floor starting from the area in which the wood was first applied. Inspect for gaps, chips and glue residue while removing the tape. Remove all glue residue, touch up chipped areas and fill with the appropriate filler as necessary. Use colored latex filler for factory finished products and stainable filler if the floor is to be sanded and finished.

2. Install/reinstall all moldings and clean the floor with the appropriate cleaner. Use a premium quality cleaner for urethane wood floors if the product is factory finished or the compatible cleaner (if required) if the floor is to be sanded and/or finished.

3. DO NOT ROLL THE FLOOR, as this will break all glue joints. 4. First use of the floor varies from one glue manufacturer to another. Generally the floor can have light foot traffic after the glue has cured for 8-24 hours with furniture being LIFTED into place after 24 hours.

5. If the flooring is UNFINISHED the glue must have a minimum of 24 hours curing time prior to finishing of the floor. DO NOT attempt to finish the floor before the glue had an adequate period of time to cure as the weight of finishing equipment may break the glue joints.
