Silicone HS M

High-solids silicone system for use over metal roofs

Silicone HS M is a high-solids silicone coating system for use over existing metal roofs. Can be warranted for up to 20 years.

System Overview

The durable Silicone HS M 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 M 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

Can Silicone HS systems be applied in one pass?

Yes. Neogard’s 7870 HS Silicone can be applied at up to 45 wet mils in a single pass. Care should be taken when applying any coating on a sloped metal roof to eliminate runs or sag.

Are seam details required for the Silicone HS M system?

Yes. All horizontal seams should be detailed with 70695 silicone mastic at a rate of 65 wet mils at 4” wide. Vertical seams should be inspected, and defective seams should be treated with 70995 silicone sealant.

What warranties are available for Silicone HS M?

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 Innovacoatings 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.
