Will Polyurethane Fill In Scratches

Yes, polyurethane can fill in scratches on a wood floor—but there are a few things you should know before you start the repair process.

For starters, it’s important to determine whether the scratch is a scratch or if it’s a gouge. A scratch is a shallow indentation in the wood that doesn’t break through the finish. A gouge, on the other hand, is a deeper cut that penetrates both the finish and the wood itself.

If you’re dealing with a scratch, you can use polyurethane to fill it in. Start by cleaning the area around the scratch with a damp cloth. Then, using a cotton swab or a small paintbrush, apply polyurethane to the area. Be sure to wipe away any excess before it dries.

If you’re dealing with a gouge, you’ll need to take a different approach. First, use a wood filler to fill the area. Once the filler is dry, sand it down until it’s flush with the rest of the floor. Then, apply polyurethane to the area using a cotton swab or a small paintbrush. As before, be sure to wipe away any excess before it dries.

Once the polyurethane is dry, your floor will look good as new! scratches and gouges included. So if you’re ever in doubt about whether or not polyurethane can fill a particular type of damage on your wood floor, remember: it can fill scratches, and it can fill gouges. Just be sure to follow the proper repair process for each type of damage.
