When painting wood, you must be sure that the wood is completely dry if you want to ensure the best results. It is possible, however, to paint damp wood if it's absolutely necessary. Follow these steps if you just can't wait for your wood to dry, but keep in mind that the best policy is to just be patient and allow it to dry thoroughly.
Dry the wood as thoroughly as possible with paper towels if it is wet to the touch.
Train an electric fan on the wood for as long as possible. This will help accelerate the drying process while you still have some time to spare. When determining how long to dry the wood in this manner, keep in mind that you'll want to apply two coats of paint.
Turn off the fan. Open and stir the water-based paint.
Apply an even coat of paint to the entire wood surface using a high-quality foam paintbrush. Allow the paint to dry completely.
Apply a second coat of paint.
Rinse out your paintbrush and clean up your working materials while the second coat is drying.
