Rust Grip® is a single-component moisture-cure polyurethane coating loaded with metallic aluminum pigment that paints directly over rust without sandblasting. One product replaces a traditional 3-product primer + mid-coat + topcoat system, bonding to metal steel aluminum concrete masonry wood and existing rust. Trusted by Chevron, Boyd Gaming, the US Army Corps of Engineers, and homeowners across America. Made in USA.

Rust Grip® is engineered to outperform traditional 3-coat systems, zinc-rich primers, andhot-dip galvanizing. Below are the verified technical performance specifications backing every project, every certification, and every case study on this page.
Nearly double standard US highway concrete (3,500 PSI).
15,000 hrs ASTM B117 perfect 10/10. Field 20+ years zero degradation.
Penetrates pores, swells microscopically, anchors into surface.
Cure begins within 1 hour. Full strength in ~3 weeks.
Food-safe, lead-free. ASTM E1795 Biohazard Encapsulator.
Top performer in 8-year Chevron USA & Workstrings study.
Because Rust Grip® cures by drawing moisture from the air, high-humidity environments actually speed up the curing process — making it the ideal moisture-cured polyurethane for offshore, marine, tropical, and industrial applications. It offers six core advantages for extreme corrosion environments where traditional epoxy or zinc-rich primers fail.
Paint directly over firm rust. No white-metal sandblasting required.
Primer, mid-coat, and top-coat in one can. No Part A + Part Bmixing.
Brush, roller, or airless sprayer. Apply on metal, concrete, masonry, or wood.
Loaded with metallic aluminum pigment for additional mechanical strength.
Continuous surface temperatures up to 325°F after curing.

Rust Grip® is a single-component, moisture-cured polyurethane loaded with aluminum pigment. Below are the specifications and application parameters verified in lab and field testing.
Rust Grip® is a tough, single-component moisture-cure polyurethane coating loaded with metallic aluminum pigment for additional strength. In most cases, white-metal blasting is notrequired. It resists chemical solvents and acid splashes. One product replaces a traditional 3-product primer + mid-coat + topcoat system, applied in 2 coats for light-to-medium rust or 3 coats for heavy rust and marine applications.
Rust Grip® can be applied to metal, concrete, masonry, and wood. Application is by airless sprayer, brush, or roller. Application thickness depends on surface profile. Standard lab testing is conducted at 6 mils DFT per coat.

Four ways to engage with Rust Grip. Pick the one that fits your project.
ABS Class Vessel Mubarak Challenger — deck application, 1+ year service
"After meeting your company at the Off Shore Arabia Conference in April 2010, we decided to use Rust Grip on the deck of our ABS Class vessel Mubarak Challenger. It has now been over a year, and there are still no signs of corrosion development as originally promised by your company."
Marine workboat — Rust Grip + Enamo Grip topcoat system, 1 year service
"It's been a year since the application of special coating of 1st & 2nd Coat (Spray) Rust Grip & 3rd Coat (Spray) Enamo Grip. The overall results of protection against environmental corrosion by the coatings is very good."
Al Mafyar LNG Carrier — hard-to-maintain areas, multi-year service
" was using it on Al Mafyar LNG Carrier for last few years and it shows excellent performance on hard to maintain areas."
State agency equipment maintenance — hydraulic rams, 2019 application
"I try to Rust Grip every piece of steel I can, because it really helps us save time and money on maintenance. Once I Rust Grip something I do not have to worry about it again. We love your product and we are always trying to make our job easier, and this is one less thing we have to worry about once it is on. The pictures with the rusted, pitted rams are from2019, where we took them off the aframe, removed the rust, applied the Rust Grip and painted them with a one part polyurethane paint."
