We bought a house in 1999, that was built in 1952. We attempted to paint the walls, since they looked like they hadn't been painted in several years. They turned out with the orange peel look........not a good look.......cracked!! Anyways, does anyone have any suggestions as to what we can do about this? Do we have to sand them?? Can we get a paint that will remedy this problem??? How about a primer? I'm not sure what kind of paint was on the walls originally........oil or waterbased....but any suggestions you guys can give me will be greatly appreciated.

So did the paint you put on crack or was it the paint already on the wall?

The paint we put on it cracked.........it looks like alligator skin. I'm not sure if we should have used oil based or what. We used flat, waterbased paint. The living room and bedroom both did the same thing.

Sounds like the original coat(s) of paint are oil based. Unfortunately oil and water based paints do not go well together (as you've found out). Now for the bad news!!! The only way to correct what you've done is to remove the paint entirely. Then make sure the surface is clean, prime and repaint with oil base.

Have fun!!

The cracks you describe are in fact called alligatoring. It is a serious adhesion problem that will require sanding or stripping. Most of the time, it is caused by painting an oil based (alkyd) paint over a more flexible latex, especially a gloss surface. Did you use an oil or acrylic type paint? Also, it sounds like this problem has ocurred on walls, rather than trim. Are you dealing with a plaster or drywall substrate?

The fix may involve sanding, skim coating or stripping. Provide a few details, we can be more help

You will need to sand and scrape the walls to remove any loose and flaking paint and then prime with a pigmented shellac primer such as Zinsser BIN which will be resistant to any hot spots that may be in the plaster which can cause this type of thing. Then you can skim out the areas that look really bad with joint compound and apply an acrylic latex primer and then the latex finish paint of your choice.

Hope this helps you out.
