Rust-oleum 301994 Elastomeric Roof Coating 7 Year 5 Gal

Product Description

The RUST-OLEUM 301994 is a 7-year elastomeric roof coating formulated for waterproofing and weatherproofing low-slope and flat roofing systems. It delivers an initial solar reflectivity of 84%, helping reduce rooftop heat gain and supporting energy efficiency targets on commercial and residential structures. This water-based coating meets or exceeds ASTM D 6083 standards and provides long-term resistance to weathering, mildew, and dirt pickup. Applied at 5 gallons per unit, it is suited for roofing contractors and general contractors performing roof maintenance or restoration work.

This coating is designed for use on metal roofing, weathered single-ply membranes, smooth-surface asphalt built-up roofing, and modified bitumen substrates. It is appropriate for both new application and roof restoration projects where a durable, reflective barrier is needed to extend roof service life. The product is packaged as a single 5-gallon pail, making it practical for smaller repair areas or multi-pail large-roof applications.

Key Features

• 84% initial solar reflectivity reduces rooftop heat load
• Meets or exceeds ASTM D 6083 elastomeric coating standard
• Rain resistant in 6 hours after application
• Mildew resistant formulation for long-term durability
• Waterproofs and weatherproofs multiple roofing substrate types
• 7-year performance rating for extended service life

Compatibility

Designed for application over metal roofing, weathered single-ply membranes, smooth-surface asphalt built-up roofing, and modified bitumen roofing substrates.

Installation Notes

Application should be performed by qualified roofing contractors familiar with elastomeric coating systems. The substrate must be clean, dry, and free of loose debris, oil, or existing coating that is not firmly adhered before application. Consult local building codes and the manufacturer technical data sheet for coverage rates, recommended application temperature ranges, and cure time requirements. Do not apply if rain is expected within 6 hours or if ambient temperatures fall outside the recommended application window.
