Preparing the Surface:

It is also important to cut a piece of mesh tape in the most appropriate size so that it fits the space and then place it over the patched area. After that, take a putty knife to apply a thin layer of patching compound over the mesh tape.

Give the patched surface enough time to dry completely. When it is properly dry, sand the patched area using a fine-grit sand paper and apply the second coat of patching compound, allow it to dry and sand the surface again. It is also important to wipe off all the sanding dust by using a vacuum cleaner or a piece of simple cloth.

Priming and Painting the Plaster Walls:

Apply a high quality primer on the plaster wall and allow the primer to dry for the maximum amount of time. You can pour good quality paint into a pan and use a roller to evenly apply the first coat of paint to the plaster walls.
