In a nutshell:

I used joint compound to correct a multitude of sins - let it dry completely, sanded smooth, then spot hit the repairs with a feathered coat of very forgiving primer. Nearly all of these repairs were 1/16th of an inch deep, the size of the palm of my hand or smaller. Everything was as smooth as silk.

When my husband rolled on the first primer coat (latex) he rolled over the some of same areas far too many times all at once and:

1. The feathered primer peeled and has made a big fat mess in some areas. It looks like someone shaved an already short hair do, and threw their hair on our wall.

2. Several joint compound fixes have swelled (I'm astonished at how much swelling can come from such a light coat of joint compound!), and are easily seen.

After all of our painstaking work, it looks like it was done by a couple of amateurs. Which we, of course, are.

What fix-it suggestions, please, might you have for us? Should I be doing something different with the joint compound?

My guess is we must now wait until the paint is completely dry (cured?), then get busy with sandpaper to sand off the problems we've created. Is my guess close to the mark? If so, does anyone have any idea how long it takes for a (ridiculously) thick coat of primer to dry enough to sand?

Does anyone have any further advice for us?

Thanks in advance!
