The recommended method for removing paint from brick walls uses a combination of paint stripper and fabric-based peeling strips. Other methods include sandblasting, power-washing and chemicals such as trisodium phosphate. These alternative methods may damage older bricks.
Thoroughly apply paint stripper gel or paste to the painted brick wall, then press on a layer of fabric strips. Allow time for the fabric to set. During this time, the paint stripper initiates a chemical reaction to soften the paint, which then adheres to the fabric. After several hours, carefully peel away the fabric along with the paint. Use protective gear when undertaking this job, and properly dispose of the paint stripper.
