Once the stain has dried, apply a clear finish to protect both the stain and the wood—and to make the final results look even more beautiful.
Wood stain is intended to be wiped off immediately after application. If the wood stain remains on the wood, liquid solvents in the stain will evaporate, leaving sticky pigments behind that will never fully dry. To remove tacky wood stain, firmly scrub the piece with mineral spirits.
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.
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.
To properly answer your question of “Do you have to seal stained wood?”, the answer is no. However, if you want to protect your wood and give it a polished finish, it's smart to do so. It's worth taking the extra steps and applying a wood stain sealer.
Most stains should be sealed to prevent bleeding. After smoothing the stained wood, apply a sealer coat of thinned shellac, sanding sealer, or other appropriate sealer. Do not use shellac with NGR or water-base stains. If you plan to finish the piece with polyurethane, make sure the sealer is compatible.

Final Thoughts on How Long to Let Stain Dry Before Polyurethane. Whether you're using water-based or oil-based stain, you need to allow sufficient time for drying before applying polyurethane, otherwise the stain and the poly will suffer. Wait at least 1-2 hours for water-based and at least 6-24 hours for oil-based.
But it's much more efficient to “bury” the raised grain with another coat of finish. Then sand it smooth after it has dried. Stains lighten as they dry, then return to their damp color when a finish is applied.
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.
Using a lint free rag is the best way to apply wood stain because it is great for controlling the amount of stain that is applied and for removing any excess stain. Also, the rag leaves a beautiful, even, and brush stroke free finish. It also can easily be thrown out once finished.
For more professional-looking results, use a sprayer or roller to apply the stain first. Follow with back-brushing to eliminate drips and runs. Stain pads do an excellent job of applying the correct amount of stain, especially on smooth wood.
You can leave wood stain overnight because it is part of the drying process. After the first coat, you should allow it to dry for at least 12-24 hours. Follow the same process for the second coat.
If applied too thickly, they won't dry properly and will remain tacky to the touch. This can also happen if the wood wasn't stripped and sanded completely down to bare wood, since the stain will sit on the surface rather than soaking into the wood.

Yes, each layer will darken your project even more. You can also start with a lighter color Gel Stain and layer on darker colors.
It's best to allow the stain to set for at least 10 minutes before wiping it off. However, remember that the time you'll have to wait will vary. You may have to wait longer (at least 20 minutes) for a darker shade. A lighter shade may require you to wipe the stain instantly.
“Staining wood usually works between 50 and 90 degrees Fahrenheit,” says Phillip Ash, the founder of Pro Paint Corner, “but the best temperature would be at around 70 degrees Fahrenheit.” Some brands or types of stains may work outside that range, but it's the generally accepted best temperature for staining wood.
You should sand after the first coat of water-based stain to flatten any wood grain the water raised, but it's unnecessary after that. You don't need to sand between coats of gel stain or oil-based stain.
Prep the wood finish for polyurethane
Before you even finish your wood project with wood stain or paint, for best results, make sure that it is sanded well and has a smooth surface. This is extremely important for not just the polyurethane top coat, but for the best wood stain or paint application too!
After applying wood stain, it's a good idea to seal it with polyurethane to protect your project. There are several different types of polyurethane products to choose from. It's important to select the one that's right for your project and apply it correctly to achieve the best results.

Oil finishes can be applied directly over prepared bare or stained wood. Only water or non-grain-raising (NGR) stains should be used; oil-base stains interfere with the penetration of the oil.
The Cons of Staining Wood
While some stains can last up to five years, postponing re-staining a wood surface for too long can cause the job to become more complex and labour intensive. Even decks that are stripped and re-stained will still require maintenance every couple of years.
