Sandblasting your home is always a risky move. No matter what the surface, you could cause some damage because of the extreme amount of pressure involved in sandblasting. For exterior house paint removal, for example, sandblasting is far too powerful for materials like aluminium siding. If you have a brick home exterior, a sandblaster is a viable option. However, you must be careful. Damage is still possible.

  1. 1

    Set the pressure on the sandblaster between 40 and 100 psi, or pounds per square inch.

  2. 2

    Add Type A sand to the sandblaster's blasting tank. Sand is an abrasive material that will help you remove the exterior house paint. Type A is gentler than Type B sand and still is abrasive enough to remove paint.

  3. 3

    Sandblast small areas of the brick at a time. Stop periodically to examine the brick to check that the surface is not being damaged but the paint is being removed. You may need to adjust the psi setting slightly as you sandblast.

  4. 4

    Scrape a wire brush along the brick to remove any stubborn patches of paint.
