HELP. Bubbles in Polyurethane finish
Hubby and I are refinishing our old wood floor ourselves. The whole house has beautiful old pecan floors, but they were unfinished....just stained. We have sanded and stained and they looked gorgeous. We decided on using Mimwax polyurethane (glossy) for floors, although I was a bit hesitant about having too high a gloss and having scuffs and dust show. Well, after the first coat we noticed that some bubbles appears and some areas looked grainy. The second coat did not improve the situation. Plus, the sheen is REALLY shiny...looks wet. HELP. How can DIY'ers apply oil-based polyurethane without causing these bubbles? Also, I had heard that the third and last coat could be a satin sheen. Because we had used gloss on the first two coats, will this third satin coat be any shinier than if we had used three coats of satin? Sorry for the length of my question. Thanks for your opinions.
