Recommended Uses
Provides elemental protection for architectural surfaces such as vertical walls, masonry, concrete, metal, and sprayed-in-place urethane foam systems.
Flammability Characteristics
Ecology Roof Systems’ Silicone Coatings carry Class “A” Non-Combustible and Class “B” Combustible credentials as tested under UL 790 procedures over spray foam and single ply roofing systems.
Installation: Do Not Thin
- Surface Preparation: All surfaces to be coated must be clean, dry, and paintable. It may be necessary to power wash and/or prime to enhance adhesion. See application specification for more details.
- Mixing Procedures: Caution: due to the combustible nature of this product, do not use an electric mixer. No thinning or reducing is necessary. Product may separate after shipping and storage, though it may still look mixed. When mixing becomes necessary we recommend the use of a ¾ horsepower or larger air operated mixer with a blade capable of uniformly mixing the entire container. When product is in 5-gallon pails, use a 3” minimum diameter mixing blade. When product is in drums, use a 6” minimum diameter mixing blade.
- Weather Restrictions: It is not recommended that this product be applied at temperatures below 50°F (10°C) or if rain is expected within 4 hours of application.
- Application Equipment: This product may be sprayed, brushed, or rolled. Due to the high viscosity of the material, a high-pressure airless paint pump capable of producing a minimum of 3500 PSI at the spray gun head should be used. The pump should have a minimum of 3 gallons per minute output and be fed by a 5:1 transfer pump to prevent cavitation. Always use components rated for pump pressure. Hoses should be BUNA-N jacketed for prevention of moisture contamination. Hoses should have a minimum I.D. of ¾” and an adequate working pressure. The spray gun should be high pressure 5,000 PSI with reverse-a-clean spray tip, having a minimum orifice of .030 and a 50° fan tip.
- System options: This product can be used as a topcoat over polyurethane elastomeric base coats where improved traffic and impact resistant characteristics are required.
- Application: This product may be applied directly to any clean, dry surface. Polyurethane foam should be coated within 24 hours of application. Subsequent coats should be applied within 48 hours of prior applications to insure full and uniform adhesion. Coating must be applied in 2 or 3 separate applications of contrasting colors, each applied at right angles to the previous coat. Coating must be evenly applied and pinhole-free. Before applying a subsequent coat of this product the previous coat must be completely dry and cured. If any contamination of a thoroughly cured surface occurs, it must be washed with a chemical cleaner before applying subsequent coats. Coating must be extended beyond the substrate to create a self-terminating flashing. Consult Ecology Roof Systems for recommended dry film thickness. Due to the bond agent present in all coating, colors may be used as either a base or a topcoat. The coating will cure in 2-6 hours, dependent on weather conditions (such as temperature and humidity) after which another coat can be applied. A #11 ceramic roofing granule may be installed in the topcoat to improve esthetics, traffic resistance and impact resistance.
- Recoating Procedures: This product may be used to re-coat existing spray-in-place roofing systems. Surface to receive recoat must be thoroughly cleaned using power scrubber, pressure washer, chemical cleaners, or air wand. Surface must be completely dry before applying re-coat.

Safety & Health
- Precautions
- This product contains combustible solvents. Keep coating material and cleaning solvents away from all sources of heat, sparks, flame, lighted smoking materials, or any other ignition source. Pumping equipment should be grounded to avoid accidental ignition due to static sparks. Avoid breathing solvent vapors. Use an appropriate MESA/NIOSH approved respirator when exposure can exceed recommended PEL.
- This product is not recommended for interior use. Additional care must be taken to prevent roof top HVAC equipment from introducing evaporating solvent into interior areas during application. Building occupants should be warned of spray operations in process. Installers should exercise caution during spray processes to avoid falls caused by stepping into slippery wet coating.
- Not recommended for continuous immersion service, for use in cryogenic tank, or cold storage roofing applications without a vapor barrier, or directly over modified bitumen, asphalt or coal tar built-up roofing systems without a sealer. NOTE: Ecology Roof Systems recommends any subsequent coats of silicone be completed within 48 hours to ensure good adhesion of the silicone coat to coat.
