Hello w0lley32, I have worked in the ink and coatings industry for 36 yrs or so and have experienced tiny bubbles forming on patching compound after sealing them with latex primer or even after a top coat with latex or acrylic paints. This may be caused by "off gasing". Because the patching compound on a smooth surface is applied in very thin film it is subject to quick penetration. Components in the patching compound react with resins and or solvents in the latex paints to form gases which bubble up through the surface of the wet paint. Even water base systems have evaporating components. For sure using an oil base Alkyd primer will prevent the bubbling but if you top coat this with a latex or acrylic (water base) paint or primer it may penetrate the alkyd and off gas again. The sure way to prevent this is to top coat with Alkyd paint but it is clear you do not want to use these products so another avenue may be to patch the bubbles with a different type of compond such as Polyfilla that dries much harder than conventional drywall compounds or even white wood filler. I've used both and had good success. You can patch a small area first ,sand and clean and test it for bubbling after you prime with a good latex. For sure you need to find a patching compound that dries with a harder finish to prevent latex penetration and off gasing, otherwise you'll get stuck using Alkyd.

I just painted a chair with Rustoleum. Followed the directions, 2 light coats in the time frame, then waited over 48 hours (as directed on the can) to go back and spray missed/ too light spots. Those spots bubbled. However, as they dried they improved, and not or only slightly noticeable now.

The bathroom was renovated it 1 years ago and was painted using Regal Paint from Benjamin Moore. The painter was supposed to use a special bathroom paint from BM " Aura Bath Paint since our bathroom does not a window- we installed a sky light and the strongest fan inside. We found out later he did not use the Aura Paint. I noticed there were some blistering paint outside the shower wall ( plumbing was the opposite site) we checked our meter- checked the rest of the wall- there are no sign of leaking. We followed the direction on how to fix the blistering and the weather was hot and humid on all the times: 1st time: sand, clean, use primer (left over), and paint (left over)- we used the bathroom on the same day-the paint were blistering again and this time spread to a different areas. 2nd time: sand, clean, primer- we let it dry for 1 day and we painted the next day- a week later - they blistering (spreading) again. 3rd time: we got a different primer-KILL Z- repeated the step on #2- The areas we fixed were OK_ but now some blistering are shown at different areas. We are running out of ideas- really trying not to REDONE the whole wall since the photo 3 - the blistering spread to a different section of wall. If we have to REDONE, can someone give us what products we have to use and maybe trying to find the culprit? I assume it could be just too humid, and my husband has not opened the sky lights but the fan has been running at extended timer after using the shower.

Bought a brand new dresser which has been spray painted by the manufacturer in a professional paint booth, and I would like to paint it another color. I've been told that I can't paint over on this smooth sprayed finish. Any advice? Thanks!
