Waterproofing Rust Encapsulating Primer

METAL-PRIME RED-OX™ is a multi-purpose, waterborne latex, waterproofing red iron oxide primer sealer. It encapsulates rust and prevents oxygen from reaching the surface and stops rust expansion in its tracks.

What Paint Will Stop Rust on Metal Roof?

Waterborne High Solids Zinc Rich Formula

Formulated with an optimum high solids blend of Zinc and Corrosion Resistant Pigments in a 100% Acrylic Waterproofing Resin base. A environmentally friendly, low V.O.C. mixture with low odor for interior or exterior use. This primer has been sealing rust for over 30 years and demonstrates the same level of performance as the “old” Red Lead and Zinc Chromate Primers.

Bonds to Most Any Clean and Dry Metal Surface

METAL-PRIME RED-OX™ has excellent adhesion to most any metal surface DTM and does not require labor intensive grinding and sanding of the existing rusted metal surface. As a true encapsulating primer you can coat over existing rust that wasn't removed during pressure cleaning.

People Also Ask

METAL-PRIME RED-OX™ combines high-solids red iron oxide, zinc-rich corrosion-resistant pigments, and a 100% acrylic waterproofing resin to provide advanced rust encapsulation and long-lasting adhesion. Unlike older solvent-based primers, it is water-based, low VOC, low odor, easy to apply, and cleans up with soap and water while delivering professional-grade corrosion protection for metal roofing systems.

Yes. METAL-PRIME RED-OX™ is designed to encapsulate existing surface rust after loose, flaking rust has been removed through proper surface preparation. The primer seals the remaining oxidation, helps prevent further rust expansion, and creates a strong foundation for your elastomeric roof coating. For best results, remove scaling rust, clean the surface thoroughly, and apply two coats of primer before the finish coating.

For maximum corrosion protection and rust encapsulation, two coats are recommended. The first coat penetrates and seals the prepared metal surface, while the second coat fully encapsulates remaining oxidation and creates an ideal surface for a compatible elastomeric roof coating. Allow the first coat to dry completely before applying the second coat.

While METAL-PRIME RED-OX™ provides excellent rust protection and can be left exposed in some situations, it performs best as part of a complete roof coating system. Applying a high-quality elastomeric roof coating over the primer provides long-term waterproofing, UV resistance, improved appearance, and extended roof life.
