can someone help me with an interior painting problem?

Question

paint peeling off walls. do I need to sand all the walls (latex enamel paint used) or do I only need to sand peeling areas and then wash rest of walls with strong solution of TSP?

Answer 1

If it is peeling in one area then it eventually will in others, you should sand it all down and start fresh. Have fun, I love painting!

Answer 2

I've been doing this for a long time, and after applying thousands of gallons of paint, I'm kind of disappointed in some answers,,,no real offense meant.

First of all what was the surface situation before applying the latex, and is it enamel?

Have you determined at all what's causing the peeling? That should be your first concern.

If you're painting latex over latex, there is absolutely no need to waste time and material in priming. That said,,, prime certainly if you're painting latex over oil, or a lighter color over a darker color, or in your case painting over peeled areas. The primer makes little difference otherwise, and there is no reason why latex can't be painted over a million times without wasting the time and energy in useless prep.

Many state use a cleaner? Are the walls dirty? Do you believe that the cleaner will aid in adhesion? Certainly you can dust the walls, even clean areas that you believe have concentrations of oils or nicotine, but I rarely clean a wall before painting.

I suggest the issue is prep, but most importantly in WHY THE PEELING. At this point, sure you'll need to sand to a feathered edge, or strip, but it seems to me there are issues that won't be taken care of just by repainting.

Not sure what kind of walls you were talking about, but I think you need to take all the peelings off now by sanding. If this was living room wall, bedroom wall or kitchen wall, (even in the bathroom) you could use water base semi-gloss paint, like eggshell or satin texture. It's easy to put it on and easy to fix when you a make mistake. I would never use enamel on my walls. You want to use enamel paint on the wood or metal surface. Good luck.

Answer 4

A lot of hard work, but I'd advise you to sand every inch of the wall reardless of it peeling or not. This way you will create a smooth finish when you paint next, it will also give you an idea of the problem behind the paint peeling. It may be damp causing this and this will be noticeable by the colour of the plaster. If the plaster is ok, then paint away! Good luck with your painting problem anyways!

Answer 5

If the paint is peeling, it's going to keep peeling. Plus, it's a good idea to sand before painting over latex.

After TSP, use a primer before painting.

Answer 6

Sand everything where the paint is peling. Then wash down the walls with a mild cleaner. Let everything DRY before you paint.

I had the same problem with paint not drying on dirty walls. Sometimes, texture on walls hides dirt.

Good luck.

Answer 7

you need sand briefly, and apply primer as a base coat, and then your latex enamel paint. Primer will cover up whatever is on the wall already, and then act as a binding agent when you apply your enamel paint, making it adhere more permanently.

Answer 8

Wash with the TSP solution. Then use primer. The primer will make the paint stick.
Hope this helps!
