112AF Foundation & Roof Coating

Karnak #112 Foundation Coating is a blend of heavy bodied asphalt cut-back and high grade solvents. This protective coating forms a smooth, tough, elastic film which gives an excellent performance over a wide range of temperature and service conditions. Karnak #112 Foundation Coating is used primarily to protect and dampproof masonry walls. The inherent strength and adhesion of this coating serve to help retard the entrance of moisture into or through the foundation wall. If a hydrostatic pressure condition is present against the foundation wall, Karnak #112 Foundation Coating is not recommended. In such cases, Karnak #86 Trowel Mastic and Cotton Fabric, or Karnak W-1 Elastomeric Membrane should be used.


Karnak #112 Foundation Coating can be used to dampproof the interior of above grade block walls and the exterior of below grade masonry walls where no hydrostatic pressure is present.


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


Do not apply to damp or frost-covered surfaces. Apply with either roller, brush or spray gun 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 the foundation. Care should be taken during backfilling not to puncture or damage the coating. A protection board is highly recommended.

BRUSH 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.


Apply the Karnak #112 Foundation Coating at the rate of 1 to 1 1/2 gallons per 100 square feet, depending upon the condition and porosity of the surface to be coated.


Tools and other equipment should be thoroughly cleaned with mineral spirits, taking necessary precautions when handling combustible materials.
