Can you skim coat concrete walls?

Yes, you can skim coat concrete walls. It’s a great way to cover up any flaws or irregularities in the surface of the concrete, and it can also help to protect the wall from moisture and weathering.

To skim coat a concrete wall, you’ll need a few supplies: sanded grout (in a color that matches the wall), water, a trowel, and a sponge. Begin by mixing the sanded grout with water until it forms a thick paste. Then, using the trowel, apply the paste to the wall in a thin, even layer. Be sure to smooth out any bumps or ridges, and don’t forget to get the edges and corners. Finally, sponge off any excess grout and allow the wall to dry.
