What happens here

If you get overspray on porous brick, the removal method depends on the type of paint. For oil-based paint, white vinegar can be effective, especially if addressed quickly. For latex-based paint, products like ammonia or Goof Off, combined with a wire brush, can be used. However, be cautious with wire brushes as some chemicals can react with the brush and stain the brick grey. A nylon brush is a safer alternative. The most critical factor is to address the overspray *immediately* while it's still wet. Pull masking away, irrigate the brick with water, and try to get as much paint out as possible. If the paint dries, it will be much harder to remove, as porous brick absorbs paint deeply.

Goal: This step provides advice on removing overspray from porous brick, highlighting different methods for oil-based and latex paints, and the importance of immediate action.
