S-20 Silicon Coating

 

 

 

 

 

GacoFlex S-20 Series are single component elastomeric waterproofing moisture curing silicone coatings. GacoSil S-20 Series are petroleum-free coatings.

Standard specification for liquid applied silicone coating used in spray polyurethane foam roofing.

 

Whether you’re covering polyurethane foam insulation on a home, commercial building or rooftop, or applying a coating to protect any other substrate, S-20 SIlicon Coatings helps you get the job done with superior results.

USAGE

GacoFlex S-20 is designed as a protective coating for spray-in-place polyurethane foam, metal, concrete, wood, built-up roofing and most single ply’s.

COLOR

  • S-2000 white
  • S-2022 medium gray
  • S-2048 tan

APPLICATION

PRIMER

None normally required.

MIXING

Mix before application to assure uniform color and consistency.

APPLICATION

CURE

Applied coating will cure in 1 to 4 hours depending on temperature and humidity.
