Product Description

EnergyGuard Silicone Coating is a solvent-based, single component, moisture cure, high solids, silicone roof coating. Containers are filled with dry nitrogen gas to prevent premature cure.

  • Breathable membrane has exceptional weathering characteristics, prevents moisture entrapment and premature roof failure.
  • Not affected by ponding water.
  • May be used for potable rainwater catchment applications. See listing at nsf.org for application and cure instructions for rainwater catchment use.
  • Reflective roof coating reduces cooling costs.
  • An excellent top coat over EnergyGuard Aromatic Polyurethane.
  • Complies with all of the requirements of ASTM D 6694-08 and -07 Standard Specification Liquid-Applied Silicone Coating and ASTM C1305 Crack Bridging Ability.
  • WARNING: This product can expose you to chemicals including Quartz and Naphthalene, which is known to the State of California to cause cancer.
Technical Data

See table on the following page.

  • Ready to use. Thinning is not necessary. Mix well before using.
  • Do not use on ponding water locations.
  • Roof must be clean, dry and free of any oil, grease, dirt or loosely adhered coating. Bare surfaces must be prepared and checked for compatibility.
  • Follow our roof restoration procedures and always perform an adhesion test.
  • Equipment: polyester brush, long nap roller, spreader or 3500psi, 3gpm airless sprayer with a .031 tip. Do not leave coating in spray guns, hoses and pumps for prolonged periods. Use BUNA-N jacketed hoses for moisture protection. Do not leave coating in spray guns, hoses, and pumps for prolonged periods.
