Fixing gas bubbles in epoxy and urethane coatings
Here are the steps for positive repair and concealment of your cratering problems. First, use a rotary scrubber and pad with a 60-grit screen to quickly go over the floor, shaving off any bubble tops and thereby flattening the floor. Next, sweep up the screening dust. Then put on those kneepads and, using a tooth paste-style tube of glazing compound and a putty knife, start filling. After all the problem craters are filled, screen again. A good second screening can be done as soon as you are finished filling. This screening will quickly remove excess glaze and blend each hole flat. Sweep again and then coat the floor.
With this extra hour of work you can be sure that the holes are all permanently filled and with no holes remaining in the floor, there should not be any new bubbles or craters. Make sure that when you mix your floor coating you don’t whip air into the mixture. Use a hand paddle for about 200 strokes then let the mixture sit for 20 minutes before using it, pot life permitting. If you suspect that your roller cover is pushing air into your product, use a mohair-style roller cover and pour the product on the floor; don’t dip the roller into it. Having the room temperature near 70 degrees and preventing wind and hot or cool spots is also helpful.
