Quick Tip to Get a Flawless Polyurethane Finish

frugalhomediy June 10, 2012 0

When applying a coat of Polyurethane it can be hard to get that flawless finish. After applying the first coat it’s customary to lightly sand the surface with steel wool, carefully clean, and then apply the final coat. However, after this process there are still little imperfections and bumps dried into the finish. These bumps really standout when looking at the surface from an angle. A quick and easy way to remove these imperfections is to lightly sand the final coat with the backside of 150 grit (or finner) sandpaper. This will smooth out the final coat by knocking down the imperfections.
