All concrete patio resurfacing projects need to be properly prepped. This can be done by grinding, as we did here, or by power washing and/or acid etching prior to applying the overlay. This helps make sure that the overlay material will tightly adhere to the concrete.
Usually, the concrete patio resurfacing will be done in two steps. The first is where we apply a skim coat that fills in small imperfections in the concrete and sticks tightly to the floor.
The second step is the actual trowel down. It is the same overlay material we used in the first, but while putting it down, we “hand whip it” to create a textured surface.
