RUST GRIP® is a tough, one-part, moisture-cure polyurethane coating that absorbs atmospheric moisture to cure. RUST GRIP® is loaded with a metallic pigment for strength and is also resistant to chemical solvents and acid splash. Upon curing, RUST GRIP® provides a protective coating film of superior adhesion and flexibility, and is resistant to abrasion and impact. RUST GRIP® can be used as a primer or as a one-coating system. It is patented to encapsulate lead-based paints and other toxic materials, including asbestos. RUST GRIP® can be applied over pressure-washed, completely dry flash rust and firmly bonded commercial paints. In most cases, a white or near-white blasting is not required. A light to medium surface rust is preferred as the profile.

 

 

TYPICAL USES:

 

• Good acid and very good alkali resistance.
• As a coating to encapsulate rust, lead-based paints and other hazardous materials.
• As a protective coating on metal, concrete, wood, etc. to add strength and prevent deterioration.
• As a one-coat system on new or existing bridges, oil platforms, roofs, and other commercial/industrial surfaces with minimal surface preparation.
• As a moisture protective membrane to stop moisture penetration, contaminants, and mold and mildew.

 

 

APPLICATION METHODS:

 

RUST GRIP® can be applied to concrete or masonry substrates. The coating can be applied by spray, brush or roller. For specific instructions on surface preparation, mixing and application, please refer to the SPI’s application instructions for RUST GRIP® (millage may vary due to surface profile).

 

Notes:

 

• This product must not be applied on or within 2 inches of chlorinated rubber.
• Never use mineral spirits to prep surfaces or to thin this product.
• For temperatures 95F/35C and above with less than 20% humidity: Rust Grip will dry to touch but will no be completely finished gassing off. If you can move the coating with your fingers, it is not set hard enough to overcoat; if overcoated too soon, bubbles will be caught in the top coat.
• Zinc rich primers >/= to 8.2 kilo of organic zinc per gallon should be removed by sandblast, hand or power tool prior to application of RUST GRIP®. Also, surface should be allowed to develop surface rust as the profile before applying RUST GRIP®.
