EnergyMax Silicone Coating


EnergyMax Silicone Coating is a solvent-based, single component, moisture cure, high solids, silicone roof coating.


For restoring and extending the life of built-up, concrete, metal, modified bitumen, single-ply (EPDM, TPO) membranes and polyurethane foam.


  • Breathable membrane has exceptional weathering characteristics, prevents moisture entrapment and premature roof failure.
  • May be used for potable rainwater catchment applications. 
  • Not affected by ponding water.
  • Reflective roof coating reduces cooling costs.
  • An excellent top coat for 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.
  • Easy to use, non-toxic and VOC-compliant silicone roof coating.


  • Ready to use. Thinning is not necessary. Mix well before using.
  • 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: brush, roller, spreader or 4000psi, 3gpm airless sprayer with a .031 tip.
  • Use BUNA-N jacketed hoses for moisture protection. Do not leave coating in spray guns, hoses and pumps for prolonged periods.

Warning: This product contains solvents. Keep away from open flame, heat or sparks. Pumping equipment should be grounded to avoid accidental ignition due to static sparks. Use only in ventilated areas and provide mechanical ventilation in enclosed spaces. Avoid breathing vapor or mist. Approved (MESA/NIOSH) chemical respirator and protective clothing must be used when exposure can exceed recommended PEL. Fresh air hose masks required for interior applications. Care must be taken to prevent rooftop HVAC from introducing solvent vapor into interior areas. Lexis Coatings must be completely dry before exposing to water or foot traffic. Keep Lexis Coatings containers covered when not in use. Dispose of all containers in accordance with state and local environmental regulations. Keep away from children. If ingested, DO NOT induce vomiting. Call physician immediately.
