Sealing Basement Brick Wall

Paul Adams asked 10 years ago

My basement is brick. Some has been painted with obvious calcification causing bulging. Some bare brick with some brick getting soft and powdery.

I am going to scrape away loose brick and calcification, then wanted to seal with a clear coat. However, I may need to use colored sealer as local Lowes doesn’t have anything clear.

Am I OK just scraping, cleaning, and painting, or is the difficulty with the outside of the house and painting as I describe futile?

Thanks for taking my question. Is there a donation I can make for this site?

The soft and powdery brick is a problem, it needs to be stabilized. This indicates water damage and the source of the water needs to be found and fixed. Also you need to use some kind of binder/sealer before painting. This will help to stabilize the brick surface.

I used a sealer by SealKrete on badly damaged brick in the past and it really helped. It was an acrylic sealer and I applied several saturating coats before painting. Maybe Lowes has something similar. If not try your local paint store.

I don't think painting your basement brick is futile as long as both sides of the problem is taken care of. Sounds like you have a good idea for the procedure to get your brick sealed.
