Total thickness is approximately 1/8 - 3/32". We are more concerned about the acrylic penetrating the concrete than building up the surface. Actually, the thinner it is, the better flexural properties it has, which is very important to allow for expansion and contraction of concrete during freeze/thaw cycles. Skim coats can be applied thicker for holes and spalling (chipping, flaking). Larger and thicker areas are filled or rebuilt using high-density acrylic mortar called Fast-Patch™.
