  5. Masonry Sand
  6. Trowel
  7. Metal Lath
  8. Caulk
  9. Mold
  10. Mildew Killer
  11. Cement

  1. First, prepare the concrete wall by removing any peeling or flaking paints on the wall. Sandblast the wall for an easier cleaning process. If you prefer not to sandblast the wall, install a metal lath over the painted concrete wall. Attach the lath to the wall by using 7/8 inch concrete screws with washers spaced 12 inches apart.
  2. Next, clean any mold and mildew and then remove any stains left by the mold. Caulk any cracks and clean the mortar joints with a wire brush. When the paint has securely bonded to the wall, use a bonding agent on the painted walls. Brush or spray the agent over the entire wall by following the manufacturer\’s instructions.
  3. Then, apply a dash or slurry coat to the concrete wall. Make mixes of 1 part of cement with 1 to 2 parts of masonry sand and enough water to create a runny consistency. Cover the entire wall to a thickness of about 1/8 inch with a dash brush. Use a slurry coat that is almost as liquid in consistency for a very flat finish.
  4. To make the plaster mix, follow the manufacturer\’s instructions. Then, apply a base coat over the dash coat that between ΒΌ and 3/8 inch thick with a trowel. Smooth the plaster to achieve a flat wall. For a textured look, leave the wall rough. Let the base coat to dry. Finally, put a second coat of plaster over the base coat using the same technique and plaster mix.
