[EX Q]: [header] How to paint masonry walls [title] Remove any flaked or peeling paint from the masonry.

This is most often done on exterior paint walls that are still meant to protect it from debris. (B) In areas where a sandblaster would be too messy and cumbersome, loose paint can be removed with a stiff wire brush and a paint scraper. [substeps] Failing to remove loose and peeling paint can result in the paint flakes mixing in with your fresh coat of paint and marring the finish. (C) [substeps] Make sure to turn off the water. Do not flush the wall down the drain. (D) If there is a paint-resistant paint strip still clinging to the wall, it may be painted to the wall as well, but not directly under it.
