Silicone HS C

High-solids silicone system for use over concrete roofs

Silicone HS C is a high-solids silicone coating system for use over concrete roofing substrates. Can be warranted for up to 20 years.

System Overview

The durable Silicone HS C system is comprised of our 7870 series high-solids silicone roof coating. 7870 series is a single-component, moisture-cured, weather-protective coating; it meets South Coast AQMD VOC standards, and is Energy Star and Cool Roof Ratings Council (CRRC) approved. Silicone HS C is intended for long-term protection for institutional, commercial, industrial, and high-rise/multi-family residential applications.

Silicone HS C forms a seamless, monolithic weatherproofing membrane for superior waterproofing, durability, flexibility, and potential energy savings. Silicone technology allows the system to perform under ponding water conditions. It is intended for long-term protection for institutional, commercial, industrial, and high-rise/multi-family residential applications.

Technical Documents

Is a moisture analysis required prior to the installation of the Silicone HS C coating?

A moisture analysis is not required but highly recommended prior to the start of work. For concrete this would consist of a mat test.

What warranties are available for the Silicone HS C coating?

We offer Material Only and Labor/Material Warranties for 10 and 15 year term lengths.

Do you have to be an approved applicator to install NEOGARD warranted systems?

You do not have to be an approved applicator to purchase material and receive a Material Warranty. You must be a Certified Applicator to receive a Labor/Material Warranty.
