Sheetrock Compound & Painting
 
I seem to have a recurring problem when I try to paint over sheetrock compound. Once it dries, I put on the primer and then apply the latex paint. More times than not, the paint will bubble and basically come right off of the wall in small sheets of dried latex. Any ideas to why this would happen? Sponging on some sodium bicarbonate before applying the primer has been recommended.

Thoughts? Suggestions?

Thanks!

do you sand it after it dries?
if so do you brush all the sanding dust off the wall?
you may be painting over the dust which is why it peels off so easy. are you letting the primer dry the recommended amount of time? are you using a good primer?

I sand it. Brush it. I've used Kilz as a primer because it was a bathroom. Does sponging it with a damp sponge do a better job at removing the dust?

oil? if not, then you need to get a better primer

That's really bizarre! What type of compound are you using?? I've never seen or heard of a problem like you're describing. Dust on the wall won't be a cause. It will just make the prime coat rough where you'll have to sand before final coat. In new construction, I've only seen one painting contractor who ever did any type of "dust removal" before priming. He had his guys use sponge mops to "wipe down" the walls before prime coat. I think the builder only used him on a house or two...

Sheetrock brand - all purpose.

Could it be the brand of paint? The finish?

you might try a new thread for better exposure.

but it sounds like the joint compound has chipped off a metal corner bead.

not just paint.
