This water-based, flexible, insulating elastomeric coating is formulated with premium acrylic resins and titanium dioxide for maximum bond strength. It forms an exceptionally protective rubber-like coating flexible enough to withstand major roof surface expansion and contraction.

It provides insulation and reduced heat absorption by reflecting 80 – 90% of the sun’s rays, reducing heating and cooling costs and promoting consistent comfort levels. Additional chemical agents provide resistance to the effects of ultraviolet sunlight exposure and help prevent the growth of mold and fungus, even in warm and humid climates.


Kool Koat MD 106 is engineered and developed to perform well under severe commercial, residential, industrial, agricultural and institutional applications. Use on asphalt, fiberglass, or asbestos shingles, concrete or clay tile, rolled roofing, B.U.R. roofs, metal roofing (baked enamel, aluminum and corrugated) and single ply roofing (EPDM,TPO, PVC). If rusted metal is present, you must apply a spot primer to the rusted area – see Metal-Koat 102 Rust Inhibitive.

Surface must be clean, dry and free of dirt, grease and mildew. Remove any trace of mildew by washing with a solution that kills mildew spores. Old coating or residue that is loose or peeling must be removed by scraping, sanding, wire brushing or pressure washing. Avoid using cleaners with built-in wax or silicone additives since this may affect coating bond. Make any necessary repairs or replacements to damaged or leaking roof material. Rusty metal surfaces should be primed with the proper material, see Metal-Koat 102, Rust Inhibitive. If repairs are needed, please refer to “Go Green Roof Repair”.

IMPORTANT: Where ponding water conditions persist beyond 48 hours, roof drains or other corrective measures must be installed to eliminate water build-up prior to coating the roof.


Maximum adhesion and durability is achieved only when the surface is clean, dry, and properly prepared. Slope for positive drainage is recommended for any roofing application. Highly weathered surfaces may require additional coverage. Apply with a brush, roller (1 1/4″ Nap), or spray equipment (Airless Sprayer- flow output 1 gpm, minimum pressure 3000 psi, tip size 0.0623(minimum)). Drying time is retarded by very high humidity. Do not apply at temperatures below 50°F. Coating should have ample time to surface dry before evening dew sets or it is rained upon.


Clean brushes, rollers, spray and other equipment immediately after use with hot soapy water.
