Repairing bubbled paint on cement wall
Hello,
I would like to know the proper steps in re-pairing a cement wall whose paint has bubbled. This is a rather small area which is a base holding a wooden décor fence between carport and outside area. It gets a lot of moisture. I have gotten a little more than half of the paint off and the rest seems tightly adhered. Can I move forward with only half the paint removed after hand sanding? I have a sealer---what is a primer paint that I see should be going on before the paint? Is it a special kind of paint or can I simply use two coats of the regular paint after sealing? Thank anyone for their advice. Jeany

If there's moisture paints not going to stay stuck to the wall.
Got a picture so we can see where this moisture may be coming from?

What kind of sealer do you have? A product like Drylok would be best for the bare masonry but even then I wouldn't garuntee it. For a paint job to hold up on a retaining wall the backside needs to be sealed and have a drain system in place. Otherwise, sooner or later, water will migrate thru the wall lifting the paint.

And just to clarify--your wall is probably concrete, not cement. Cement (actually, Portland cement) is a fluffy, gray powder, that by itself has no strength. It is one of the key ingredients of concrete, and which hydrates with water and other ingredients to give concrete its strength.
