Spalling concrete

Hello, does Sakrete resurfacing work for minor spalling concrete foundation walls?

Spalling concrete

Before you just throw something on the spalled (if that what is really is) area, you should find out why it spalled and make corrections first.

The solution may depend whether it is interior or exterior, block or concrete and the conditions.

If you just want a cosmetic patch, there are many materials designed for that purpose.

Dick, thanks for the reply. That's what I thought I was doing. I am not looking for quick fix. I am looking to do what is best to preserve the concrete. These are 60 year old concrete foundation walls that have been painted at least a couple of times. Were talking about the interior. I have only been here 3 yrs and don't know any specifics about the paint or when the spalling started. The spalling is not everywhere. There are patches. When I first moved in, there was a small amount of water that came in with rain. I fixed that by re grading, fixing the gutters/downspouts and caulking some steps. I think that possibly moisture was trapped in the walls by the paint and then the Chicago area weather took over from there. Regardless, this is kind of scaling/spalling. 1"x1"x.25"and less deep. When I first started on it, you could rub your hand across it and it would fall off. I have taken off all of the loose concrete and paint that I can. Where there is no spalling, the paint is too hard to remove, but the surface is still pretty rough. I am a structural engineer and don't see any structural problem. I am trying to protect the concrete from the elements and further detioration. What do you recommend?

Great forum, thanks for your time, Tom
