Plaster A Concrete Wall
Plaster has been around for a long time now. It was commonly used in homes a very long time back. Some say that plaster was used as far as in the 1950s. May people like it then as it was easily made, which made it popular, cheap and easy to find. Even now, there are even more people who just love to have plaster in their homes.

Another way to change the appearance of your concrete wall is to apply plaster. Plaster will make your concrete wall even more resistant to the moisture and add a nice texture as well. Although plastering a concrete wall will take some of your time, preparing yourself with the needed tools and of course, the right steps will ensure a successful ending as well as the perfect results. Here are the steps on how to plaster a concrete wall.
You will need:
- Sandblaster
- 7/8 Inch Concrete Screws
- Wire Brush
- Bonding Agent
- Masonry Sand
- Trowel
- Metal Lath
- Caulk
- Mold
- Mildew Killer
- Cement
- Plaster
Steps:
- 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.
- 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.
- 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.
- 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.
