  1. Wash the wall

    In a bucket, make a paste of dish soap and salt. Add a little water, and mix the solution until it is the same consistency as cream. Apply the mixture to the wall, wait 10 minutes, and work it into the brick with a scrub brush. Rinse the wall thoroughly.

  2. Replace damaged mortar with caulk

    Inspect the wall for chipped and rough mortar. Remove the imperfections with a putty knife, and fill them in with masonry caulk. Put on rubber gloves, then dip one finger in water, and run it over the fresh caulk until the surface is smooth. Let the caulk dry according to the manufacturer's recommendations.

  3. Mix the plaster

    Read the instructions on the plaster tub, and open it. Mix the plaster with water, and put some of it into a small bucket.

  4. Apply the plaster

    Cover the ground with drop cloths. Set a ladder at one end of the wall, and climb it. Bring a trowel and the small plaster bucket with you. Apply a thin layer of plaster, starting at the top of the wall and working down in parallel lines. Move the trowel in upward diagonal strokes. Let the plaster cure for 30 minutes, refill the small plaster bucket, and apply a second coat. Give the plaster six weeks to harden.

    How do you remove paint from a brick wall?

    A:

    There are five ways to remove paint from a brick wall: sandblasting, a heat gun, a peel away gel/paste, a regular paint stripper or environmentally friendly strippers like Soy Gel or Citristrip. Brick walls that have been painted before 1970 may contain lead, so it is best to use a method that allows for containment of the paint as it is removed from the brick.
