OK, we finally got around to staining our screen porch and deck, both built in the winter of 2018-19. Pressured-treated southern yellow pine, now well aged. We hired a professional painter and things did not go well today. Attached is a photo. Covered with hundreds -- thousands -- of tiny bubbles. Painter says he doesn't know what happened ... does anyone here?
Background: About a week and a half ago, we prepped with power-washing and then Sherwin Williams Deck Wash and lots of rinsing. Painter used a brush to cut in and apply stain between boards, then rolled on a thick coat of stain (Sherwin Williams semi-transparent oil). The outside deck -- which had aged much more and was splintering and beginning to crack -- didn't get these bubbles. But the screened porch floor, which looked BEAUTIFUL and almost brand-new several hours ago, now looks like this.Painter thinks he can sand it off and apply another coat tomorrow.
Ideas?
The wood was probably wet internally and then stain could not soak in. You will need to remove all 100% to fix and start over.
Painter is now sanding and plans to try again. Word to the wise: use a composite deck. This isn't worth it.
Update -- we've given up. Sanding and another coat of semi-transparent oil didn't help. Bubbles still there, but now stain so thick it covers up the grain and looks like semi-solid paint. What do we get to strip it all off? And can we ever go back with a semi-transparent again? Painter and paint company say wood must have held moisture (for the past 2 years?) and we need to switch to latex rather than oil? Latex, they say, won't have this fish-eye effect from painting on dampish wood...
You cannot strip this off. As we mentioned earlier, the only way to fix this is to 100% sand it off. Sounds like he did not do this and made it worse by partially sanding this and applying more on top.
OK, yeah, it's a mess. The project has been halted.
