Allow 2 to 3 hours to dry before applying another coat. We recommend applying two or three coats of paint. If the paint doesn't cover after 2 coats, you're not applying enough. Water-based polyurethane requires at least two hours of drying between coats, and you should only apply two coats in one day.
It's important to remember that drying time is affected by temperature and humidity. The ideal temperature range for applying water-based polyethylene is between 60 and 90 degrees Fahrenheit, with a humidity level below 60%. Depending on the type of dye you use, most stains dry and heal within 24 to 48 hours. After that time, it's safe to apply additional coats or apply polyurethane or the sealant of your choice.
When an oil-based product is applied to a water-based product and vice versa, the drying time increases. It is extremely important to ensure that the first finishing application has completely dried before applying the next coat. When you switch from an oil-based product to a water-based one, wait 72 hours to apply the next coat of product. When you switch from a water-based product to an oil-based one, wait 24 hours.
