Rust-oleum 301997 Fibered Aluminum Roof Coating 5 Gal

Product Description

The RUST-OLEUM 301997 is a fibered aluminum roof coating formulated for rust-proofing and weatherproofing metal roofs, sidewalls, and low- or steep-slope roofing assemblies. The metallic pigment delivers 53% initial reflectivity, helping reduce heat absorption and supporting overall energy efficiency. One coat applies direct to tight rust with no primer required, making it a practical option for maintenance crews and roofing contractors working on existing metal substrates. It also guards against mild acid and alkali fumes and provides long-term UV protection rated for 7 years.

This coating is suited for commercial and residential roofing applications where metal surfaces, built-up roofing systems, or modified bitumen membranes need reflective protection. It is also approved for use on transite panels and other compatible masonry-adjacent substrates. Roofing contractors, facilities maintenance technicians, and experienced DIYers working on metal panel roofs or low-slope BUR systems are the primary installers. The 5-gallon pail is sized for mid- to large-scale roofing jobs.
