How to fix polyurethane mistakes?

It’s polyurethane that makes your wood projects look shiny and protects them from scratches for a long time. As polyurethane is famous for making furniture and floors looking shiny, mistakes in polyurethane are popular too. And the popular polyurethane mistake is to find traces of bubbles on the surface.

Once you have gathered all the above things, you need to follow the below steps to get rid of polyurethane mistakes: 

  • Step 1: First, you need to detect the uneven area or where the bubbles are formed. However, if you pop the bubbles while applying polyurethane and let it dry naturally, you can avoid this mistake in the first place. Use fine-grit sandpaper and try not to sand too harshly unless you want to remove the full coating. So you need to keep in mind that you are trying to remove the bubbles and make the surface finish even. 
  • Step 2: Now the next step is to clean the area where you have sanded. However, if you don’t have a vacuum, use a clean cloth first to remove dust and debris before cleaning with a broom. It will help you to clean the area more neatly, then mop the surface to double cleaning. Also, it’s a necessary step to get a clean and beautiful finishing. 
  • Step 3: The last step is to re-apply a polyurethane coat again on the sanded area. Make sure you apply thin layers of coatings by using a brush. The brush has to be lint-free; otherwise, it will ruin the coatings again. Now let the layer of polyurethane dry properly; do not use a fan to fasten the drying process. 

Now check if the layer you have applied is too thick or not. If you see the new coat is too thick, then re-sand the area again to even the surface. But if the layer is too thin, then don’t be afraid to apply another coat. In a word, you need to make the floor or furniture even.
