Maibec® Resistech™ Siding Read this before applying

Apply touch-up paint to all cut and to all bare siding, in order to fully protect the siding against water and rot. It is necessary to do all the touch-up, even if a sealant or H-moulding will be applied after installation.

1. StorageWinter: The paint must be kept in a heated area (between 4°C/40°F and 38°C/100°F) for a minimum of 24 hours prior to usage.

Summer: Keep out of direct sunlight.

2. ToolsUse polyester, nylon, or any synthetic applicator with firm bristles approved for water-based coatings.

3. Paint PreparationStir for at least 1 minute using a wooden spatula, making certain to scrape the sides and the bottom of the can until it is homogeneously blended. This should be repeated a couple of times (at least every 2 hours or as needed) over the course of a day’s work.

4. ApplicationFor maximum adherence, visible touch-ups should be done at temperatures above 10°C/50°F. Do not apply touch-up paint to wet siding or trim.

a. To touch-up small areas such as nail heads or scratches, use an applicator no larger than the intended surface. Carefully dab the area.

b. Apply touch-up paint to all cut surfaces and to all bare siding, even if it is not visible once the siding is installed. It is easier to touch-up boards before they are installed.

c. All exposed face nails must be properly sealed in a manner that prevents moisture intrusion and water buildup.

d. Do not use wide brushes that could cause drips and give poor results.

“TOUCH-UP PAINT” IS ONLY MEANT TO BE USED IN THE AREA IN NEED OF IT. IT MUST NOT, UNDER ANY CIRCUMSTANCE, BE APPLIED OVER NON-DAMAGED FACTORY COATED MATERIAL. DIFFE RENCES IN TONE DUE TO THE MISAPPLICATION OF TOUCH-UP PAINT WILL NOT ALWAYS APPEAR IMMEDIATELY, EMERGING ONLY AFTER REPEATED ULTRAVIOLET EXPOSURE.

MAIBEC® IS NOT LIABLE FOR ANY VARIATION IN COLOR DUE TO THE INCORRECT APPLICATION OF TOUCH-UP PAINT. MAIBEC® WILL NOT BE LIABLE FOR ANY VARIATIONS IN SHEEN OR TONE AND FOR CHALKING.

TRIM & FASCIA 190, 440, 540 & 2000 SERIESPREPARATION

• Do not use staples.

• Trim must not be in direct contact with masonry, concrete, brick, stone, stucco, or mortar.

• Minimum 6 inches (152 mm) clearance must be maintained between trim and finished grade. (See diagram 2a)

• Trim applied adjacent to roofs, porches, patios, sidewalks, etc. must have a clearance of at least 1 inch (25 mm) above any surface where water might collect. The surface must be sloped or otherwise designed to provide proper drainage so the trim is at no time directly exposed to standing water. (See diagram 2b)

• A non-corrosive drip-edge must be applied at bottom edge of roofing where it meets the fascia. (See diagrams 2c and 9c)

• In a horizontal brick frieze or band board application where the trim meets the masonry leave a 3/8 inch (10 mm) minimum airspace and flash between the trim and the masonry.

(See diagram 2d)

GENERAL REQUIREMENTS (CONTINUED)

• For the cleanest cut and longer blade life, a fine-tooth carbide tipped blade is recommended.

• Trim and fascia are manufactured with a special edge coating which reduces moisture-related issues. Do not rip and/or rout

the trim and fascia, as it will leave the edges unprotected.

- If the trim or fascia materials are ripped, you must take special care to seal all wood exposed to the weather as described in the Finishing Instructions. (See page 12)

• Climb cut the surface of the trim and fascia such that the rotation of the blade cuts downward on the primed or prefinished surface.

• Do not miter trim ends or edges. 45 degree diagonal cuts of trim ends around door and window opening is acceptable, as well as joining. (See diagram 2e)

• Moisture control and moisture vapor control are critical elements of proper housing design and construction. Check your local building codes for application procedures for handling moisture and water vapor in your area.

• Follow all applicable building code specifications relating to prevention of moisture intrusion into the wall assembly. LP SmartSide trim and fascia are wood products, and, as with all wood products, must be kept free from excessive moisture. Lack of proper ventilation; exposure to constant or repetitive sources of water such as sprinklers, condensation, inadequate flashing; improper sealing; or failure to follow common building practices that prevent moisture intrusion into the wall system may cause damage, and products subject to such treatment will be excluded from warranty coverage.

• As with all wood products, do not apply engineered wood trim and fascia to a structure having excessive moisture conditions such as drying concrete, plaster, or wet blown cellulose insulation. If such conditions exist, the building should be well ventilated to allow it to dry prior to the application of the trim and fascia.

• Gutters with kick-out flashing and eave drip edge are recommended for control of roof water run off. (See diagram 3b, 3a, 2c and 9b)


• Apply nails to meet the specifications in the General Application Equipment section in this document. (See diagram 3c)

framing a minimum of 1 inch (25 mm) will require additional support from a construction adhesive. First, use hot-dipped galvanized ring-shanked nails no smaller than 0.092 inch shank diameter to attach the trim sufficiently to secure the trim to the structure while the construction adhesive completes its curing process. Second, use an exterior grade construction adhesive that meets the following specifications.

Construction Adhesive Specifications: − Minimum bond strength: 300 psi − Minimum application temperature: 40° F − Paintable grade

Alternative Fastening Option - Installing Over Insulated SheathingsLP SmartSide Trim and Fascia may be installed over low-compression rigid foam or exterior gypsum. The following precautions must be followed: • Adequate bracing of the wall in accordance with the International Codes or other ruling building code is required. • For rigid foam sheathing up to 1 inch (25 mm) thick, trim may be nailed directly to the foam sheathing unless a drainage

plane is required by the local building code. Nail length must be increased to ensure a minimum 1-1/2 inches (38 mm) fastener penetration into the structural framing.

• For rigid foam sheathing greater than 1 inch (25 mm) thick, a minimum 1-1/2 inches (38 mm) thick by 3-1/2 inches (89 mm) wide vertical strapping or furring strip must be installed over the sheathing to provide a solid, level nailing base for the trim. The strapping must be securely fastened to structural framing spaced no greater than 16 inches o.c. (406 mm) with a minimum nail penetration of 1-1/2 inches (38 mm) and a maximum nail spacing no greater than the width of the siding.

Louisiana-Pacific assumes no responsibility for any damage or condition arising from the use of rigid foam or exterior gypsum.

• Trim must extend beyond the face of the siding. Trim may be installed directly to the sheathing, or directly over the siding.

Horizontal trim: properly integrate flashing with siding, WRB and vertical trim. At corners, allow the end of the trim to overlap the end of the adjoining trim. Leave a 3/16 inch (5 mm) space and seal with sealant. (See diagram 6a)

Vertical corners directly to sheathing: allow for proper spacing between the trim edge and siding. Corner trim edge may lightly touch adjacent trim edge. Follow siding manufacturer’s application instructions. (See diagrams 6b and 6c)

Vertical corners over siding: the width of the trim must overlap the siding by a minimum of 2 inches (51 mm). Sealant between the trim and siding is not required for this application. Allow for proper spacing at the corner between perpendicular siding pieces. Corner trim edge may lightly touch adjacent trim edge. Follow siding manufacturer’s application instructions. (See diagram 6d)

OPTIONAL Pre-assembled vertical corners: cut vertical corner pieces to size with clearance requirements in mind. Set perpendicular corner pieces and pre-drill fastening holes a minimum of every 24 inches (610 mm) o.c. Fasten into pre-drilled holes with proper nails or screws. (See diagrams 6e and 6f )

LP SmartSide Trim Adjoining Stucco, Brick or Cultured Stone:

When using LP SmartSide trim with stucco, brick or cultured stone, it is important to use a capillary break so moisture absorbed into the stucco, brick or cultured stone cannot transfer into the trim. • Avoid Direct Contact between the trim and stucco, brick or

cultured stone.

• Separate with a minimum 3/8-inch (10 mm) space and a high-quality sealant (backer rod may be required as per the sealant manufacturers instructions). Additional space may be required by the manufacturer of the stucco, brick or cultured stone cladding. (See diagram 8b)

• Other types of impervious material such as aluminum flashing can be used to separate the trim from the stucco, brick or cultured stone but the dissimilar materials should be properly spaced to allow for different rates of thermal or moisture-related movement.

• Apply sloped Z-flashing over horizontal trim so water that may get behind adjoining cladding can be redirected to the outer surface of the wall.

• Install the trim according to the LP SmartSide Trim and Fascia application instructions.

• Install the stucco, brick or cultured stone cladding in a manner consistent with the manufacturers installation instructions.
