108AF Asphalt Primer

General purpose, penetration asphalt primer used for the preparation of all types of surfaces previous to the application of hot or cold asphalt coatings. Karnak #108 Asphalt Primer is a controlled preparation of a highly ductile, soft asphalt in a refined solvent.


  • ASTM D-41
  • Fed. Spec. #SS-A-701
  • AASHTO M-116


It is especially designed for use as a general utility prime coat for concrete, gypsum, masonry, brick and metal surfaces over which waterproofing, dampproofing, roof coatings and other asphaltic products are to be applied. This thin solution readily penetrates pores and seals dusty masonry surfaces to provide a firm base for such coatings. It is specified as a prime coat previous to the application of the membrane system of waterproofing on all concrete structures. It is also very efficiently used as a felt primer on old dried out built-up roofs where penetration is required to revitalize the base surfaces before roof coatings or cold applied systems are applied.


All surfaces to be primed or coated with Karnak #108 Asphalt Primer must be dry and free from oil, grease and any other foreign matter.


Easily applied by brush or spray equipment at the rate of 1/2 to 1 gallons per 100 sq. ft. depending upon porosity and type of surface being primed. Masonry and dried out built-up roof structures should be liberally coated to obtain the most penetration so that an effective bond can be achieved for the covering material.


Apply at the rate of 1/2 to 1 gallons per 100 sq. ft.


Brushes and other tools may be thoroughly cleaned after use with mineral spirits, taking the necessary precaution when handling combustible materials.


Do not use near open flame. Avoid breathing solvent fumes and prolonged contact with skin. Do not take internally. If swallowed, do not induce vomiting. Call a physician immediately. Keep out of reach of children. Keep container covered when not in use. Do not thin. Dispose of in an environmentally safe manner.
