I have cleaned about a square meter of internal house brick using a brick acid. I am using this area as a feature, and the bricks came up really clean and looked good. The appearance was enhanced because I had washed the residual acid off the area and the wall was still damp. Can I reproduce this appearance using a brick sealant, and if so what type. The area is internal and would a brick sealant peel over time? Thanks Tooly.
