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.
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.
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.
A change in texture is the biggest visible sign that something has gone wrong. Traditional wood stain should still be a liquid. Gel stain should still be a pudding-like texture. Any indication that the stain has separated, turned stringy, dried up, or had any other change in texture is a sign that it's gone bad.
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.
Instead, it will create a tacky surface, which may be prone to early peeling. Because the additional coat is not penetrating the wood, it is simply layered on top, which will cause the coat to be more fragile and will not offer the same level of protection as the proper amount of stain.
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.
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.

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.
If you used a penetrating oil stain, you may have allowed the stain to build up too thick a coat on the surface of the wood. Penetrating wood stains are not intended to be a surface finish. If applied too thickly, they won't dry properly and will remain tacky to the touch.
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.
Depending on your project, you will not need to remove old stain before restaining. If you want to darken the stain on your wood project, then removing the existing stain is not necessary!
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 apply a second, unnecessary coat of stain to wood that is already adequately covered, you risk creating a tacky surface that is prone to early peeling because the second coat is not penetrating the wood surface, but simply laying on top of the first coat of stain.
Negative staining employs the use of an acidic stain and, due to repulsion between the negative charges of the stain and the bacterial surface, the dye will not penetrate the cell. In negative staining, the results yield a clear cell with a dark background. (c) 2009 by John Wiley & Sons, Inc.
No, the sticky stains will not dry after some time, which is why it is important to wipe off the excess wood stain. If you don't, your work will end up sticky because the stain did not dry properly. You will have to use mineral spirits, more stain, or sandpaper to fix the mess.
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.
Removal is Not Always Necessary
In some cases, you can get away with leaving the previous coat as it is, as long as you perform the other necessary preparation steps, such as sanding and power washing.
Make sure you sand the wood well before applying stain. Any scratches will be enhanced by stain. Sanding will also help open up the pores of the wood so that they can absorb stain better. Start with 80 grit to remove big scratches and imperfections, then move up to 120 and finally 220 grit.
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.
Letting Stains Sit Too Long
It can be tempting to throw the soiled item in your laundry hamper and let it sit until your next laundry day, but the longer a stain sits, the harder it can be to remove completely—especially it the stain is colorful or greasy. So rinse and treat those stains promptly!
