How long after staining can i apply polyurethane

If you can, bring your project into a climate-controlled environment, or simply wait for better weather. Humidity refers to the moisture content of the air. When the air is already moist, it is more difficult for the solvents in the stain to evaporate, and this slows the dry time significantly.

In very humid weather, you may have to wait twice as long as the product label advertised before you can apply polyurethane. By the same token, an extremely dry environment will encourage stain to dry more quickly. Running a dehumidifier in your workspace on humid days is an effective way to combat slow dry times.

Air moving over the surface of the stain will help it to dry, allowing you to follow up with a coat of polyurethane in the smallest possible amount of time. You can also set up a fan or multiple fans to blow across the work surface. Dust or insects may stick to the stain while it dries. You can carefully sand the surface with very fine grain sandpaper to remove debris without removing the color.

Both stain and polyurethane come in water-based and oil-based formulations. Water-based poly can be applied over water-based stain without a problem. The same goes for oil-based formulations. Theoretically, it is possible to apply water-based poly over oil-based stain. To do so, you must ensure that the oil-based stain is completely dry. If possible, try to stain in a lower humidity environment, or put the project off until you have a less humid day. Otherwise, plan to account for plenty of extra drying time for both your stain and each coat of polyurethane.

Not only does humidity affect drying time, but it can also cause a cloudy look in your poly topcoat. Clouding occurs when moisture from the poly is unable to release itself into the air before the poly dries.

Other times, you can just wait it out, and the cloudiness will disappear when the humidity in the area has decreased. Besides fans, open all of the windows in the room to increase air circulation further. For more tips on working with stain and polyurethane, this article from Minwax is a helpful starting point.

I built houses for over 30 years and recently retired. So the logic behind this myth, which is fairly new, is that the finish will dry faster if the thinner evaporates faster. When you apply polyurethane , you notice that it stays wet on the surface for a short time as the thinner evaporates. Then the finish goes into a tacky or sticky stage for an hour or longer. An oil based polyurethane is a slow drying finish which is a little more tolerant.

High humidity will greatly extend the drying time. Where in warm dry weather the finish might dry enough for another coat but when the humidity is up you probably should wait 24 hours.

If you apply poly before the stain is adequately dry, you 're going to end up with stain mixing into your poly , poly that takes forever to dry, or worse.

In some cases, applying poly over wet stain can reduce the bonding ability of the poly , which will end up ruining your finish over time. How long after staining can I polyurethane? Every finish and stain is different, and drying times can vary widely from brand to brand or product to product. As a rule of thumb, you should wait hours to allow the stain to fully dry before applying your polyurethane.

If you're extra cautious, you may even choose to wait 72 hours before applying your poly. Why is my stained wood sticky? Stain becomes sticky on a wooden surface because it doesn't have a binder, such as you find in paint or varnish. When the solvent evaporates, all that remains is the pigment and the oil that is carrying it. An easy way to remove this is simply to apply another heavy coat of stain.

Ohio Posts 6, Although I've gone right from stain to applying poly finish - with no drying time in between, and, never had a problem - - both with oil based poly and water based poly yes - WB poly over wet oil stain Listen to the other two posters above.

I was also ready to take all the blame for it had something bad happened. I never had a problem doing it - but - - that means exactly nothing. Guys also stop and bend their elbow a bit too much on their way home on Friday night, then get behind the wheel and weave their way home - - and nothing bad ever happens to them either Doesn't make either right My granddad always said, :As one door closes, another opens".
