Fresh wet paint should be soaked up with an absorbent material without wiping the paint, as this will spread the stain. It should then be treated with a suitable solvent, such as white spirit, and then the area washed with a de-greasing agent taking care in the disposal of the run-off material.
Brick is porous, so paint sinks into all the grooves on the surface. Chemical and gel masonry strippers are the solution for inside walls; and while the process of stripping the brick is not complicated, it involves multiple applications of stripper and lots of scrubbing, making it a time-consuming project. It is impossible to scrape like wood, and interior walls cannot easily be water- or sand-blasted.
Pressure washing should NEVER be used as it can quickly erode the surface of bricks. Some caustic chemical solutions can cause surface failures or can change the color of old bricks. Rapid deterioration is then likely to occur, resulting in the need for major repairs
With dried paint, the paint should be scraped off as far as possible and then a paint remover to BS3761 (4) should be applied.
