Floor Finish Bubbles

Below we ll look at the causes and find out how to prevent these issues.

Floor finish bubbles.

I have a maple laminated floor. The process is called screening and it s one you can use on any existing finish not just a new one. Screening is another option. While blisters and bubbles may look similar they re unsightly either way their causes are quite different.

Outgassing is a site condition that allows air or gas from the concrete substrate to escape in excess and cause blisters craters bubbles or pinholes. This happens to floor finishers who drag the finish applicator aggressively and then must stay off the floor until the finish dries. Causes of floor coating blisters. What would you do.

I would contact the installer and manufacturer. As such it is only effective with polyurethane finishes. Carefully remove the finish clean the space let it dry then apply two to three new coats of finish until the color of the finish matches the rest of your floor. After the floor finish has hardened enough to sand it refinishers pass over it with a floor buffer fitted with a 120 or 150 grit sanding screen to remove bubbles before applying another coat.

Bubbles where sun hits laminate floor. In the sun a few spots of the finish have bubbled and cracked. This method gets rid of the finish without removing any of the wood beneath. When bubbles appear in a freshly applied epoxy coating the most common culprit is something called outgassing.
