This high quality, single component, elastomeric coating provides a long lasting waterproof membrane on a flat or a sloped roof. The coating is made from silicone, allowing for superior protection against permanent ponding water, UV rays and temperature extremes. Due to the unique chemistry of GacoElastomeric, it can be rained on after 2 hours and won’t wash off the roof. GacoElastomeric adheres directly to the substrate and does not require a primer. Use it to protect large and small buildings, homes, garages, patio covers, sheds, barns, mobile homes, RVs and more.
Two coats are recommended for sufficient waterproofing coverage on most substrates. Apply at
a rate of 100 sq. ft. per gallon in each coat on a smooth surface; coverage rate may decrease on
heavily textured or weathered substrates. Allow the first coat to dry for 3 to 12 hours. Apply
second coat as soon as the first coat can be safely walked on. Do not apply in temperatures
below freezing, above 120°F (49°C) or if rain is expected within 2 hours. Light foot traffic is
allowed for equipment servicing only.
Flat roofs (less than 1:12 pitch/5°): Use a solvent-resistant 3⁄4” or 1” nap roller cover and dip
roller directly into pail and apply, or pour product onto flat roof surface and roll out evenly.
Pitched roofs (greater than 1:12 pitch/5°): Use extreme caution when on a pitched roof. Follow
all safety guidelines to avoid injury. Use a solvent-resistant 3⁄4” or 1” nap roller cover, dip roller
directly into pail, and apply. A roof pitch greater than 4:12/19° is not considered walkable;
Additional reach equipment may be needed to properly apply the product safely and effectively.
BENEFITSTwo gallons of GacoElastomeric provides the same coverage as a 5-gallon pail of most acrylic elastomerics, plus the added benefits and protection of a Gaco Silicone:
BETTER COVERAGE. Higher solids than acrylics, more coating stays on the roof. One 2 gallon container of GacoElastomeric covers 100 sq. ft.
CURES FAST. Can be rained on after just 2 hours and won’t wash off the roof.
WITHSTANDS PONDED WATER. Acrylics begin to soften in as little as 24 hours.
REMAINS PERMANENTLY FLEXIBLE. Acrylics become hard and brittle, and often crack and leaks.
IDEAL FOR FLAT ROOFS.
