112AF Foundation & Roof Coating

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. The finished coating forms a smooth, tough, flexible film that serves to help retard the entrance of moisture into or through teh foundation wall. On the roof it helps to extend the life of a variety of roofing systems. 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.


Karnak #112 Foundation & Roof Coating can be applied on exterior below grade and interion above grade block and masonry walls where no hydrostatic pressure is present. Use to coat all types of smooth surface asphalt roofs. Can also be used to protect wood and metal above or below grade.


All surfaces should be clean, dry and free from oil, grease, dust, dirt, loose paint or other foreign matter.


Apply by either brush, roller or heavy-duty airless spray equipment in a smooth continuous coat over the entire area. Coating should be continuous and free of pinholes or holidays. If not, apply a second application at right angles to the original coat. Allow at least 24 hours drying time before backfilling against the foundation. Care should be taken during backfilling not to puncture or damage the coating. A protection board is highly recommended. Do not apply over damp or frost covered surfaces.

BRUSH ROLLER APPLICATION: Be certain to work the coating into all cracks, holes and crevices. Apply to a uniform consistency.

SPRAY APPLICATION: Utilize standard heavy duty spray equipment. Equipment manufacturer should be consulted for more complete information.
