So how can you skim coat concrete surfaces?īefore you start a skim coating project, it is important to properly prepare the area first. It also helps protect against water damage by creating an impermeable barrier between the interior and exterior environment.Īdditionally, skim coating provides better insulation than traditional materials like plasterboard because it has fewer gaps where heat can escape from your home during cold weather months.įinally, skim coating makes cleaning much easier since dirt won’t get stuck in crevices as with other types of wall finishes. One major benefit of skim coating is its ability to level out uneven surfaces which can make them easier to paint afterward. It’s important that this step is done carefully so that there are no air bubbles or ridges left behind after the material dries. The material will then dry and harden into an even coat that covers any imperfections on the original surface. Skim coating involves using a trowel or squeegee to apply a thin layer of cement-based material over the existing surface. This technique is often used on interior walls and ceilings but can also be applied to concrete surfaces such as driveways, patios, and sidewalks in order to improve the look and feel of the area.
