#83 Brush Mastic: is a carefully prepared composition of selected asphalts, mineral fillers and suitable solvents. It is prepared to a semimastic consistency for easy application, by brush or spray methods. This material dries to a tough, black, flexible and corrosive proof coating which gives excellent performance over wide ranges of temperature and service conditions. Provides an excellent dampproof barrier for masonry and other surfaces. Complies with all requirements of ASTM-D-2823.
This product is recommended for application as a dampproof coating for the exterior of masonry walls below grade. The inherent strength and adhesion of this product serves to retard the entrance of moisture into or through foundation walls. It can also be used for the dampproofing of interior faces of exterior masonry walls above grade, and for all backup materials for masonry such as stone, brick, or concrete. Also available in Non-Asbestos Grade.
#86 Trowel Mastic: is manufactured from a blend of selected asphalts, mineral fillers and suitable solvents. It is made in a trowel consistency which dries to a tough, black, flexible and corrosive proof coating. The elastic nature of the dried coating provides excellent performance over wide ranges of temperature and service conditions.
Complies with all requirements of ASTM-D-2822. This product is recommended for application as a dampproof coating for the exterior of masonry walls below grade. The inherent strength and adhesion of this product serves to retard the entrance of water and moisture vapors into or through the foundation walls, It is also used for the dampproofing of interior faces of exterior masonry walls above grade and for all backup materials for masonry such as stone, brick or concrete. Also available in Non-Asbestos Grade.
#102 Asphalt Primer: This Non-Fibrated Dampproofing Primer is a carefully prepared composition of selected asphalts and solvents. This material dries to a tough black finish which gives excellent performance over a wide range of temperature and service conditions.
#108 Asphalt Primer: A thin preparation of highly ductile, soft asphalt in a selected hydrocarbon solvent. 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 asphalt products are to be applied. This thin solution readily penetrates the pores and seals dusty masonry surfaces to provide a firm base for such coatings. It is specified as a primer coat impervious to the application of the membrane system of waterproofing on all concrete structures. Complies with Federal Specification SS-A-701a and ASTM D-41.
DAMPROOFING: NON-ASBESTOS EMULSION BASE PRODUCTS
#100 Non-Fibrated Emulsion Coating: is a general purpose Non-Fibrated emulsion coating prepared from an asphalt binder, carefully refined and emulsified in water by means of selected mineral colloids. The asphalt emulsion thus produced is of heavy paint consistency and contains no fillers or fivers.
This material is a tough, flexible, black-asphalt compound especially designed to provide excellent protection of all surfaces from corrosion and weathering. Ideal for use as an emulsion primer or as a dampprofing coating. Complies with all the requirements of ASTM-D-1187, Type 1 & 11
#220 Non-Asbestos Fibrated Coating- Brush or Spray: This product prepared with the highest quality asphalt and mineral fillers for brush or spray application of exterior walls below grade and cavity walls above grade and other exposed surfaces. This dampproof coating is prepared by the emulsification of a non-volatile asphalt in water by means of a selected mineral colloid. This product is then homogenized, thoroughly dispersing fibers within the mixture, completely eliminating lumps and clots for smooth application.
Karnak#220-Brush Grade complies with ASTM-D 1227, Type 1V (Non-Asbestos)
#920 Non-Asbestos Fibrated Coating – Light Trowel: This non-pollutant product is composed of a non-volatile bituminous binder carefully refined from straight Venezuelan Asphalt crudes and dispensed in water by means of selected mineral colloids. The asphalt emulsion thus produced is fibrated with mineral fibers.
It has excellent adhesion on all types of walls and thoroughly protects the surface by permanently sealing it against the transmission of moisture saturated air or other disintegrating conditions. Karnak #920 is also used as an adhesive for adhering Styrofoam insulation to masonry walls, Karnak #920 complies with ASTM-D-1227, Type 1V (Non-Asbestos).
#925 Non-Asbestos Fibrated Coating – Heavy Trowel: This material is of the same composition as Karnak#920 with the exception that it contains a higher percentage of mineral fivers and has been especially designed for unusually severe conditions, that require a heavier coat for added insulating value and protection.
