Basic Uses & Description:
Home-Sil RP 1.3 Rust Block Primer is a water-based, rust inhibiting, low VOC primer developed to protect metal roofing systems. Home-Sil RP 1.3 Rust Block Primer is based on self-crosslinking technologies that allow for low VOC levels along with greater corrosion resistance and adhesion properties. Home-Sil RP 1.3 Rust Block Primer has excellent resistance to large temperature swings, moisture, and weathering. This primer dries quickly, allowing for reduced time before top coating application. Home-Sil RP 1.3 Rust Block Primer may be used as a prime coat over primarily metal surfaces but can also be applied to a wide range of substrates which include, but are not limited to, wood, metal, concrete, masonry, various single ply membranes, spray polyurethane foam and most other commonly used roof coatings. The dark red color speeds up drying and increases roof surface temperature to prep for application of a roof coating. Low VOC levels allow for application in most air quality restrictive areas around the country.
Limitations & Precautions:
Home-Sil RP 1.3 Rust Block Primer is a water based primer and is not freeze-thaw stable. It will freeze and become unusable at temperatures below 32°F. PROTECT FROM FREEZING DURING SHIPMENT AND STORAGE. Do not apply Home-Sil RP 1.3 Rust Block Primer when ambient air and substrate temperatures fall below 45° F, or when inclement weather is forecast. Apply next coating as soon as possible after primer cures. Do not leave Home-Sil RP 1.3 Rust Block Primer exposed to elements beyond 48 hours as weathering and dirt pick-up will compromise adhesive performance properties.
Home-Sil RP 1.3 Rust Block Primer is available in 5 gallon containers.
