Kathy Staff asked 4 years ago

We are getting ready to paint an old bathroom. The paint has alligatored. What preparation is necessary? I believe the old paint is enamel. Do we need to sand down the old paint?

1) Scrape off anything that is loose.
2) Sand to level off rough edges, if possible.
3) Prime with an oil base primer. Something that dries fast.
4) Spread/apply drywall joint compound over the affected areas. Let dry and sand smooth and level with surrounding wall.
5) Reprime fixed areas then paint.

This assumes the walls are smooth without any texture. If textured you will need to retexture the repaired areas before painting.
