Staining wood is a great way to change the color and appearance of your furniture or floors. However, it is essential to wait for the appropriate amount after staining before applying polyurethane. Polyurethane is a clear finish that helps protect the wood from scratches, water damage, and other wear and tear.
If you apply it too soon after staining, the stain may not adhere properly to the wood and could be easily damaged.
After you’ve stained your woodworking project, letting the stain dry completely before applying a polyurethane finish is essential. Depending on the type of stain you use, this can take anywhere from several hours to a full day. Once the paint is dry, lightly sand the surface with fine-grit sandpaper to help smooth out any imperfections.
Then, wipe away any dust with a clean cloth, and you’re ready to apply polyurethane.
