How to Fix Bad Polyurethane Job
No one likes the look of a bad polyurethane job and unfortunately, it does happen. Polyurethane is a tough and durable material, so when it is not applied properly or evenly, it can really detract from the overall look of any piece. Thankfully, there are a few ways to fix a bad polyurethane job, without needing to redo the entire project.
Tools and Supplies You’ll Need
- Sandpaper – Preferably three-hundred to four-hundred grit
- Shop Vacuum – For dust removal
- Cloth – For cleaning
- Polyurethane – For patching up the finish
Steps to Follow
- Start by using the sandpaper to lightly sand the raised, inconsistent bumps or ridges that make up the bad polyurethane job. Again, it’s essential to use a fairly fine-grit sandpaper so that you don’t make the surface worse than it already is.
- Once your work surface is as smooth as possible, use a shop vacuum to get rid of all the dust that was created during the sanding process.
- Clean off the surface with a damp cloth. You want to make sure there is no sawdust residue left anywhere.
- Apply the new polyurethane to the surface with a cloth, dipping the cloth into the polyurethane and then wiping it across the surface. Make sure to go back over the area with your cloth once you have applied the polyurethane to make sure that it has been evenly spread out and there are no drips or streaks.
- Let the polyurethane dry for twenty-four hours before touching up or using the piece.
By following these steps it’s possible to fix a bad polyurethane job, allowing you to enjoy the finished product once again!
