Is there any way to prevent bubbles when applying polyurethane on old wood (it had paint on before but got removed, if that matters)? I just applied the first coat, will it be better after I lightly sand this coat with fine sandpaper and then apply a second?
I am using Minwax Fast Drying Poly Semi-Gloss, not because I needed fast drying but because that's all they had at Lowes. Could the fast drying property be causing the bubbles. Using single use sponge brush and 4" roller.
