Karnak #112 Foundation & Roof Coating is a non-fibered asphalt coating for preventing moisture penetration through foundation walls and protecting a variety of roof surfaces. If a hydrostatic pressure condition is present against the foundation wall, Karnak recommends using a Karnak waterproofing product such as Karnak 88R Rubberized Waterproofing (Aqua-Block), or Karnak 229AR-Elastomeric. The finished coating forms a smooth, tough, flexible film that serves to help retard the entrance of moisture into or through the foundation wall. On the roof it helps to extend the life of a variety of roofing systems.
