Gaco S2000 (S20) Solvent-Free Silicone Roof Coating
Petroleum Free Gaco S-2000 is a non-sacrificial, solvent-free silicone roof coating. S-2000 is class A fire rated, with 84% reflectance, 93% emittance, and limited dirt pickup.
Sharing the same chemical backbone as sand, S-2000 demonstrates excellent physical properties. Non-sacrificial means it won’t break down over time, so the same number of “mils” applied today won’t reduce or wear away tomorrow.
Solventless S-2000 makes waterproofing a breeze, for new construction or retrofit projects. Breathe easy with S-2000.
S-2000 is ideal for the following Roof Types:
- Sprayed Polyurethane Foam
- Aged Asphalt
- Cap sheet
- Modified Bitumen
- Aged EPDM
GacoFlex S20 (S2000) Series are ideal for use as a maintenance coating system over pre-existing
elastomeric roof coatings, metal roofs, built-up roofing, mineral cap sheet, and weathered single ply
membranes (EPDM, Hypalon®, and TPO/CPA) on a roofing substrate where the membrane
surface is in sound condition, but requires a renewal of the membrane surface due to the normal
effect of aging and use.
GacoFlex S20 Series Coatings are the standard specification for liquid applied silicone coating used
in sprayed-in-place polyurethane foam roofing systems.
GacoFlex S20 Series Coatings may also be used over concrete, coatings, and over plywood
decking when properly applied over an approved base coat; please contact Gaco Western for
