UBOND AP+water based GLOSS/ MATT lacquer for WOOD

100% ECO FRIENDLY 0 VOC

FAST DRYING

Best reason for using UBOND AP+ finishes is that it dries fast, especiallywhen compared with brushable varnishes and polyurethanes .

In most cases, a typical UBOND AP+ coating will be dry to the touch in 5 to 10 minutes and can behandled, sanded, and recoated within an hour. If you spray finish, you will find that drying times for

UBOND AP+ finishes are comparable to those of traditional lacquers and shellac.

Drying times for UBOND AP+ finishes can't be beaten. Even so-called "fast-dry" polyurethanes take

least an hour to dry to the touch and many more hours before they can be sanded and recoated.

The fast-drying properties of UBONS AP+ give them definite advantages over solvent-based product

especially when applying them by brush.First, because UBOND AP+ dries so quickly, the chances of dust settling into the wet finish is

significantly reduced. This mean s you can achieve a better finish with less work and the working

environment doesn't have to be absolutely spotless to get a good finish.

Also, multiple coats of fast -drying finish can be applied quickly. Under the right conditions, it is notunusual to apply three or four coats of finish in one day.

CLEAR DRYING AND NON YELLOWING

The exceptional clarity of most water based products makes them the ideal choice when you want the

finish to protect the wood but not change its color. UBOND AP+ finishes with great success overpickled, painted, and colored furniture. Use UBOND AP+ topcoats when trying to match a difficult

shade of stain. Once the color of the stain is right, you don't want to worry about the topcoat changingits shade by making it darker or more amber in tone. Also, UBOND AP+ won't yellow with age the

way most lacquers and varnishes do, which makes them a good choice for finishing light-colored

woods like ash and maple.

DURABLE AND SCRATCH RESISTANT

The resins used in UBOND AP+ finishes have improved to the point where most products are at least

as durable, if not more so, than solvent-based materials. UBOND AP+ forms a tough, flexible film this highly scratch resistant and can withstand most forms of abuse, including heat, alcohol, acids, alka

oils, greases and most common household foods and chemicals.

WHEN ARE UBOND AP+ FINISHES APPROPRIATE?

UBOND AP+ finishes are appropriate in just about any situation imaginable. If you need a hard,

scratch-resistant finish that is easy to apply and dries fast, UBOND AP+ would be a good choice. Ifyou are looking for a clear, non yellowing finish for light colored woods or "pickled" furniture,

UBOND AP+ products are for you. If you want to spray your finishes but don't have a proper spray

booth or good ventilation, then nontoxic, nonflammable UBOND AP+ is the safest choice.

Because UBOND AP+ finishes are nontoxic, they are not only safer for you and the environment butare also a good choice for finishing children's furniture and toys. Also, the low-odor, high scratch-

resistance, fast-drying characteristics of UBOND AP+ products make them ideal for wood floors.

SandingWith UBOND AP+ finishes, use sandpaper up to120 grit before applying the first coat of finish.

Prewetting to reduce WOOD GRAIN RAISING

For an exceptionally fine finishon a piece or if you want to minimize the amount ograin raised by the first coat of finish, you may pre wet the surface before applying the seal coat.

Simply, this involves wetting the wood, letting it dry, then sanding it. The water raises the grain just

the water in the first coat of finish would, then after the wood has dried, the stiffened fibers are sandeoff.

Use a spray bottle to apply a light mist on the wood, but you could also use a rag or sponge. The key

to get the surface of the wood damp, not to soak it throughout.

After spraying or wiping on a light coat of water, let the wood sit until dry. On a warm, dry day, woo

that has been given a light misting may be ready to sand in 15 or 20 minutes.

If the application of water is heavier or if the weather is cold or humid, the piece may need to dry for hour or two.

e.g.: if dry sanded to 120 grit, you may use 180 grit to smooth the raised grain. However, never wetsand above 220 grit, since anything finer will not do a good job of removing the stiffened fibers.

The type of paper used when wet sanding is really a matter of personal preference. Use a silicon

carbide paper that is designed for both wet and dry sanding. Often called wet/dry or auto paper, it iseasily recognized by its evenly sized grit and black color.

Using paste fillers

In some cases, the final finish you are trying to create may only be achieved by first filling the pores the wood. This is especially true when working with open grained wood s like oak, mahogany, ash, a

walnut. Although there will be times when you want to maintain that open grained look, there will beother instances when you want the finished surface to be as smooth as possible.Using paste fillers on your project not only helps to create a surface that is like glass but also allows

you to introduce another element of color into the final finish.

When discussing paste, or pore, fillers, it is important to note the distinction between a wood filler ana wood putty. Fillers are used to fill the open pore s on the surface of the wood.

They are used to give the wood a smooth, glassy surface and can also be used to impart interesting

colors and contrasts in the appearance of the wood.

Putties, on the other hand, are used to fill cracks, nail holes, gaps, and other defects.Similarly, fillers should not be confused with sealers. Sealers are clear liquids that contain many of th

same properties as a film-forming finish.

Sealers do just what their name implies- they seal the surface of the wood. They can either help to seafinishes like stains and dyes in the wood or to prevent more finish from penetrating the wood .

If you do plan on putting a UBOND AP+ topcoat over an oil-based filler, be sure to let it drythoroughly. Wait at least two or three days and, if possible, up to a week before applying the topcoat.

We also recommend applying a coat of dewaxed shellac as a sealer to avoid any potential adhesion

problems. Test a sample piece first before mixing these two products on a completed piece of furnitur

APPLYING PASTE FILLERS

Before you begin applying a paste filler to your project, remove all of the dust that resulted from

sanding. Dust left in the pores of the wood may prevent the filler from adhering properly. In fact,

you may end up removing most if not all of the filler when wiping off the excess. Since dust getsembedded deep in the pores of the wood, simply wiping the surface with a rag or brush won't do. Thebest way to remove all of the dust is with a blast of compressed air. If you don't own an air compresso

you can resort to the next best thing lung power.

MAKING YOUR OWN PUTTIES

Here is a quick and easy alternative that usually makes small cracks and nail holes virtually disappear

First, squeeze a tiny amount of PVA EMULSION into the void. Be sure to use enough PVAEMULSION to fill the hole but don't use so much that it makes a mess of the surrounding wood.


4/4

Let the PVA EMULSION set for a few minutes, then take a piece of 220-grit sandpaper and begin

lightly sanding the area on and around the defect. The fine sawdust that is gene rated will begin to stito the PVA EMULSION, eventually covering it completely.

Because you are using dust from the wood immediately surrounding the defect, the color is the same

and the void seems to disappear. Plus, because the dust is stuck to the PVA EMULSION and not mix

with it, it takes stain and finish pretty much the same as the surrounding wood. Just be sure tothoroughly sand any excess PVA EMULSION off the surface of the wood, otherwise it will show

through the finish .While we don 't recommend this for large defects, it does work well on small nail

holes, cracks, and voids .

When applying UBOND AP+ topcoats over solvent-based fillers and stains, give the solvent-based

product plenty of time to cure. Keep in mind the difference between cured and dry. A pigmentedstain may be dry to the touch in a matter of a few minutes or hours, but it will not be fully cured until

all of the solvent has evaporated .
