Stains lighten as they dry, then return to their damp color when a finish is applied.
Many, probably most, store-bought stains are made with both dye and pigment. If wood stained with these stains is exposed to sunlight or fluorescent light for a while, the dye color will fade away, but the pigment color will remain.
Why does this happen? Depending on the type of wood you're staining, the color of the stain can change. You have to take into account the hardness and undertones of the wood you're using. Both of these things affect the stain color.
Leave the stain on the wood longer before wiping it off. This allows some of the thinner to evaporate and that increases the ratio of pigment to vehicle.
If the color is then not even, or it's too light, you'll need to apply more stain. Switch to a slower drying stain, work on smaller sections at a time, or apply and wipe off the stain faster by using a cloth or spray gun to apply the stain and a large dry cotton cloth to remove the excess stain.
In that case, another coat of stain (after the appropriate dry time) might even out the color, especially when you are using a lighter color. It's important to remember, though, that a second coat of stain will NOT hide sanding marks.
Depending on the type of stain you are using, most stains are dry and cured within 24 hours to 48 hours. After that time, it's safe for additional coats or to apply polyurethane or the sealer of your choice.
Any excess stain will redissolve and come off, leaving only the stain that penetrated into the wood.
We always recommend two coats of stain for any wood project, but you should only apply as much stain as the wood can absorb. Extremely dense hardwoods may only be able to absorb one coat of wood stain. The general rule of thumb is to apply only as much deck stain as the wood can absorb.
If you leave it on for too long, the chemicals in the stain can start to break down the surface of the wood, causing it to flake off or peel. Sometimes, the excess stain may redissolve, giving you undesirable results.
When first applied, window tint may appear darker than anticipated. However, as it cures and dries the film will lighten slightly. If after some time your tint still looks wet with no prospect of drying or curing in sight, do not hesitate to reach out to a professional tinting shop for assistance.
Using most gel stains, you can darken wood furniture, or stay the same color, without sanding off the old stain. But, I usually use General Finishes Gel Stain because the finish always looks beautiful. Don't forget to Save or Share these steps for how to stain wood without sanding.
If you try to use a lighter shade over a previous stain that is darker, it wont make a difference. Or, it may even appear darker after it's dried.
If a pigment or wiping stain (those that contain a varnish, lacquer or water-based binder) gets the wood too dark, try removing some of the color by wiping with the thinner for the stain or with lacquer thinner or acetone. These stains are much more difficult to lighten than dye stains.
Staining has the extra step of removing the excess stain before it dries. You want to make sure that you remove any excess before it dries. If excess is allowed to dry on top of the wood, it leaves a glossy sheen on the wood that doesn't match the rest of the wood. This can give your wood a blotchy look.
Apply a second coat of stain after the first has dried fully. This will usually produce a slightly darker coloring with the excess wiped off. Substitute a glaze or gel stain for the liquid stain. Glazes and gel stains usually contain a higher ratio of pigment to vehicle.
The longer a stain is left untreated, the less likely it is to be removed. When a spill first occurs, it sits on the surface of the fabric, but over time, that spill can start to react with the fabric causing the fabric to actually change colors.
With staining, you'll know if you've over-applied your deck stain because there will be sticky patches or puddles that just aren't drying—the wood has absorbed all it can, so the remaining stain has nowhere to go.
Resist the urge to run it under the hot tap. “Don't add hot or even warm water to a stain, as this can end up having the opposite effect of setting it permanently, particularly if the stain is protein-based, like milk or blood,” says Verity. “Always use cold water for the safest result, but avoid over-wetting it.
The way to get the smoothest and best-feeling finish is to “rub out” the last coat using sandpaper and abrasive compounds. Methods of doing this are written about often. It's a mechanical procedure that doesn't differ all that much from sanding the wood.
Dried stain will feel dry to the touch, not sticky or tacky.
Let your stain dry for the recommended time on the can before touching, which can be anywhere from 2 to 24 hours. Then, just touch the wood! If it feels dry, your wood is likely ready for another coat of stain or a sealant.
Treat stain immediately. Soak 30 minutes or more in cold water. Rub detergent into stain. If stain persists, place a small amount of household ammonia on the stain and rub again with detergent.
