Louisiana Department of Transportation

Approved for use on Qualified Products List.

Passed 1500 hour Salt Fog Test


Mississippi Department of Transportation

Approved for use on Qualified Products List.


Tennessee Department of Transportation

Acceptable for encapsulation of galvanized Guardrails.


University of Kentucky

Georgia Department of Transportation

Field tested by applying RUST GRIP directly over the steel structure and concrete support columns to fill and seal the voids and gaps in the surface tying the structure together.

The bridge when new was built and tested to a 10 ton load capacity. After years in service, it dropped to only a 3 ton capacity caused by deterioration. Surface and structural repairs were made and RUST GRIP was applied to the entire surface of the metal and concrete surfaces.

D 6904 Resistance to Wind-Driven Rain for Exterior Coatings Applied to Masonry

Test Procedure: Testing was conducted in accordance with ASTM D 6904 except no block filler was used. The coating was applied in two coats. Each coat was approximately 4 mils wet film thickness with a minute dry between coats. The coating was allowed to cure for twenty-one days before testing was conducted.

Conclusion: The coating conforms to the requirements of the superseded Federal Specification TT-C-555B, as tested.

D 7088 Resistance to Hydrostatic Pressure for Coatings Used in Below Grade Applications Applied to Masonry

Objective: To evaluate the hydrostatic pressure resistance of a submitted water-proof coating.

Procedure: RUST GRIP applied to exterior of 8” masonry cube having 1˝ thick walls. Allowed to dry for 21 days. Testing was conducted at 4 psi. as outlined in the method.

Conclusion: The sample of RUST GRIP does not exhibit any water droplets or blistering when tested. The sample conforms to the requirements as stated in the Federal Specification TT-P-1411A Paint, Copolymer-Resin, Cementitious for Waterproofing and Masonry Walls.

Window Cycling Test – VTEC


Laboratories – New York

Preparation: RUST GRIP was used to encapsulate a double-hung window removed because of having LBP (leadbased paint.) A machine was devised to use an electronic opening and closing rotary wheel with a digital counter specifically for this test. This allowed the window to be opened and closed at two second intervals.

Procedure: The test was designed to measure friction wear of a coating over LBP to find the failure point of friction wear that would expose the hazardous LBP. The tested window completed 20,000 cycles of opening and closing, which is equal to the opening and closing of a window once a day, every day for 54 years.

Conclusion: A visual inspection showed no wear or friction burn through, and no LBP exposed after 20,000 cycles. Wiping test with a sterile gauze pad proved no LBP.
