GacoRoof is a single component elastomeric air dry silicone rubber coating that can be applied

year round on properly prepared substrates. GacoRoof meets the requirements of ASTMD 6694.

GacoRoof GR1600 (white) meets the requirements for the Energy Star reflectance performance

requirements for both low and high-sloped roofs and the requirements for the Cool Roof Rating

Council. GacoRoof GR1600 (white) meets solar reflectance and thermal emittance requirements

for: the 2012 International Energy Conservation Code (IECC); the ASHRAE 90.1 Energy

Standard for Building Except Low-Rise Residential Buildings; and the California Building Energy

Efficiency Standard CEC-400-2008-001-CMF, as adopted as Part 6 of Title 24.

This product is list by Underwriters Laboratory.

USAGE:

GacoRoof is designed as a protective coating to seal and repair existing roofs and permanently

protect against leaks, permanent ponding water, and the damaging effects of severe weather.

LIMITATIONS:

Not for use on 3-tab asphalt or architectural shingles. May

require multiple coats to create a

seamless membrane. May require GacoFlex E5320 2-Part Epoxy Primer/Filler. Verify adhesion

with a GacoRoof AdhesionTestKit.

Ft./Gallon (9.3 Sq. Meters/3.8 L) to yield 11 dry mils on a smooth surface. Coverage rate may decrease on textured surfaces, and more coating will likely be used on first coat than on additional coats.

Smooth roofs can be completed in 2 coats, lightly textured surfaces often require 3 coats, and heavily textured surfaces may require 4 coats to achieve a final 22 dry mil film build. Do not apply in temperatures below freezing, above 120°F (49°C) or if rain is expected within 2 hours.
