Envir-O-Sil Roof Coatings System

The Process

It is important to review application guidelines for each specific roof, as coverage rates do vary, but the process of installing either Envir-O-Sil System remains fairly consistent for each of the suitable substrates:

  • Pressure Wash
  • Look for problem areas
  • Apply an appropriate AWS Primer if and as needed
  • Waterproof splits, transition areas, penetrations, and any area of concern with one of AWS's flashing grade materials
  • Apply the AWS High Solids Silicone 412 Base Coat
  • Apply the AWS High Solids Silicone 412 Top Coat

Many building owners are not aware that roof restoration is an intelligent alternative to roof replacement. Most roofs can be restored for a fraction of the cost of a new roof and can be sustained indefinitely. Urethane and silicone roof coating systems are being used by companies of all sizes to waterproof and cool their buildings and improve their bottom lines.
