Sanding Painted Dry Wall - Without Damage?

Question

I have a main bathroom where some of the paint has peeled or chipped. I want to gently sand the dry wall in spot locations, but I am afraid of making the wall worse. There are some minor bubbles in the dry wall that I would like to sand or buff. I heard liquid sander is good, but have no experience with it. I plan on buffing or sanding the dry wall and then applying Kilz Premiem primer and then 2 coats of paint. What products would you recommend for gently sanding or buffing spot locations of the dry wall?

Answer 1

Liquid sander?

Sounds like you need a small piece of a medium to fine (100 grit) grain sandpaper and a hand sanding block. Just sand lightly and you can control how much you take off by how hard you press down. Don't use coarse, 40-60 grits, they will leave scratches and marks you'll have to fill.

I forgot, they make these spongy foam type sanding blocks that are really easy to use and they come in different grits. Great for small jobs and do less damage. You can rinse them out and reuse them too.

You might need a 2nd coat of primer, depends on how fast and far it soaks into the drywall.

Answer 2

I think you should sand of scrape off the peeled and chipped paint and then do a "skim" coat of drywall mud to the whole thing. You'll have to lightly sand the skim coat and put a paint primer on it, but you'll be glad you took the time and effort to do it. Have your shop vac handy when you do the sanding and put plastic sheeting over the bathroom doorway to cut down on the sanding dust wafting into the rest of the house.

Answer 3

Darby may be right about scraping and a skim coat of float. You may want to re-stipple when finished. If the "bubbles" create an indentation, use a piece of tape.
Without using sand paper, there are "screen" hand sanders that will create less fine dust.
