So obviously, wood stain is dangerous during the application and drying process. However, the dangerous solvents evaporate out of the stain as it dries, which is part of the reason the vapors are so dangerous. What is this? The good news is, though, that once the wood stain is fully dry, it's no longer toxic!
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.
All wood stains are toxic in liquid form but become non-toxic after fully cured. This process can take 3 to 30 days, depending on the kind of stain and brand. As the stain dries, volatile organic compounds, or VOCs, release into the air.
Many varnish products contain benzene, a highly flammable carcinogen. It also emits a strong odor with intense fumes that cause drowsiness, headaches, skin irritation, and dizziness. High exposure can even cause unconsciousness and respiratory distress.
Most oil-based stains must dry for at least 12 hours before they are exposed to any moisture/rain; however, Ready Seal, if properly applied to prepped and dried wood, can get wet within a couple of hours, and it won't wash away. Oil-based stains will generally take 24-72 hours to fully cure.
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.
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.

For oil-based polyurethane, it can take up to 24-48 hours for the finish to dry and up to 72 hours for the fumes to dissipate completely. Therefore, it is recommended that you stay out of your home for at least 72 hours after applying an oil-based polyurethane finish.
When wood products are worked on, dust and formaldehyde are released into the air. Prolonged exposure and inhalation of these products may cause cancer of the nasal cavity, sinuses and nasopharynx, as well as leukaemia.
How Long Will the Wood Stain Odor Last? Unfortunately, if you used an oil-based stain, the wood stain odor could last for months or even years, according to the U.S. Green Building Council.
Off-gassing is heavy during the first two days after application, and the floor's finish can continue to emit small amounts of VOCs for up to thirty days. The best way to mitigate off-gassing is to follow a few steps: Turn up the heat to speed up drying time.
Using Interior Wood Stain
When staining indoor wood furniture, shelving or other interior pieces, you'll typically apply the stain with a brush or cloth, let it penetrate the wood (without drying) and then wipe off the excess. With some stains, you can darken the color with a second coat after several hours.
If you stain a deck without cleaning and prepping it first, the results will look blotchy, uneven, and, well, amateur. Any time you save skipping the cleaning stage, you'll spend twice over repairing the botched job.
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.
hazy white stains are caused by moisture trapped between the finish on your table, and the wood itself. They are caused by water or condensation sitting directly on the wood. For example, condensation dripping off ice-cold water glasses, or hot food plates resting on the table.
If you stain your deck in the summer, make sure you do it out of the direct sunlight. Applying a deck stain in direct sun will cause the stain to dry to quickly and can result in premature stain failure. In the summer, stain your deck in the morning or evening so the deck surface isn't too hot.
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.
Similarly, you should always check a wet garment to see if the stain is gone before putting it in the dryer. The heat of the dryer can set the stain and make it permanent.
After staining wood, you will want to finish with a topcoat sealer to protect your wood project. Apply a sealant and let it fully cure before handling!
Let water-based stains dry for two to three hours and oil-based stains for four to six hours before applying a polyurethane sealer. The best way to get a smooth finish is to apply the first coat of sealer, let it dry, and then lightly sand the surface with 220-grit sandpaper before applying a second coat.
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.
Applying a topcoat sealer is not required, but a finish protects the stained wood from scratches and keeps it from fading over time. If applying a polyurethane wood finish with a brush, apply one to two coats. If using a spray can, hold 8 to 12 inches from the surface and apply two or three light coats.
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.
