• Rust Grip® Specifications and Uses


    • Encapsulate and seal lead-based paints, asbestos, or other hazardous materials
    • Corrosion and weathering protection. Rust Grip® is UV-controlled and is not affected by hostile environments
    • Overcoat rusted areas to prevent and control further corrosion. Rust Grip® will seal out any contact with moisture and air or chemical pollutants that breed corrosion activity
    • Prime metal with Rust Grip® before over-coating
    • Protect floors to prevent wear and damage, whether concrete, metal or other materials
    • Anti-slip coating when combined with aggregates, for use around high traffic areas
    • Protection from acid splash or pooling. Rust Grip® will not allow acids to penetrate to affect the surface
    • Proven/tested under ASTM as a "water-barrier" over concrete, block and masonry.


    Although Rust Grip® can be applied by non-professionals, SPI recommends using a SPI certified applicator.


    • Surface must be clean and COMPLETELY DRY, with no loose debris or particles, dirt, oil, films or residues of any kind. Rust Grip® will cover surface rust and other coatings if they are fully adhered to the surface
    • Stir well, as the metallics tend to settle out before use. If application is slow requiring several hours, restir every 30 minutes.

    Application methods

    • Airless or pot sprayed: tip size .015 - .017
    • Non-rusted steel: apply in one coat using crosshatch method
    • Rusted steel: apply in two coats using crosshatch method
    • Apply first coat to work into rusted, pitted, porous, irregular shapes, seams and cracks to allow penetration.
    • Within 30 minutes (if hot and humid) or up to 4 hours or even next day (if cool or cold), overcoat with second coat to assure no surface pin holes. The first coat penetrates and leaves pinholes to anchor itself.
    • For other surfaces apply in two coats
    • Roller or brush: apply in two coats
    • Add an additional coat for heavily rusted vertical surfaces

    Applied rate

    • Rusty - 200 sq. ft./gal. (18 sq.m./gal.) (two coats - applied 350 - 400 sq ft./coat)
    • Non-Rusty - 300 sq. ft./gal. (27 sq.m./gal.)

    Film thickness

    • Wet: Rusty - 5-8 mils (125-200 microns). Non-Rusty - 6 mils (150 microns)
    • Dry: Rusty – 4 mils (100 microns). Non-Rusty - 3 mils (75 microns)


    • 32 degrees F (0 degrees C) – 200 degrees F (93 degrees C
    • 72 degrees F (22 degrees C best

    Dry times

    • 1 hour to touch at 72 degrees F (22 degrees C)
    • Overcoat immediately after surface is dry to touch
    • Must be overcoated within 2 hours or within 1 hour after surface is dry to touch)

    Full cure

    • 21 days


    • Rust Grip® is so tough it will not wash off hands using solvents after 30 minutes
    • Do not leave unused portion of pail opened for longer than 4 hours


    • Silver / grey in color. Rust Grip® cannot be tinted because of metallics in the formula.
    • Not for use over wet or moist surfaces. Surfaces must be COMPLETELY DRY
    • Not for use in situations of constant underwater exposure
    • Not recommended for use around high ammonia levels
    • Not for use on food preparation surfaces that are in direct contact with foodstuffs
    • Rust Grip® has excellent coverage and appears to be very well applied only after one coat because all the surface looks a very nice silver/grey color. You cannot see the pinholes from the first coat and this causes some applicators to think it is "good enough" and not apply the second coat as instructed.
    • Cannot be used in conjunction with organic zinc
  • Rust Grip® Frequently Asked Questions

    What surfaces can Rust Grip® be applied to?

    RUST GRIP® can be applied to aged or new steel or aluminum, concrete, wood, and rusty or corroded steel and aluminum

    How is Rust Grip® sold?

    5 gallon pail and 1 gallon cans

    Can Rust Grip® withstand chemicals?

    Rust Grip® has been tested against 1,500 different chemicals and is only unsuitable for continuous immersion in ammonia and urea derivates.

    What’s the difference between Rust Grip® and a rust converter?

    Rust Grip® works by penetrating through and coating over the rust to it against further expansion. Rust converters work by chemically changing the rust into a benign form which only lasts for 3 months and must be overcoated.

    What precautions do I need to take when working with Rust Grip®?

    Practice standard safety precautions when working with Rust Grip®, including protective clothing. Rust Grip® will adhere to and cure on skin. Rust Grip® is USDA-approved (with original 1992 approval letter) and safe, but it will wear on skin for several weeks before being sloughed off with normal skin renewal.

    Because Rust Grip® works rapidly, do not leave a container open to the air for longer than 4 hours, or Rust Grip® will draw in the ambient humidity and begin to cure. Use caution when resealing the container, as any Rust Grip® on the seal track of the lid or container may cause the two surfaces to seal. A brush or roller used to apply Rust Grip® cannot be cleaned.

    How do I clean off Rust Grip®?

    As long as it is immediately cleaned after it is applied, Rust Grip® can be removed with xylene or MEK. There is no way to remove Rust Grip® when it has set. Brushes and rollers must be thrown away. Flush spray machine, hoses and gun with solvents to clean out. When breaking for lunch, seal off Rust Grip® container, run solvent through the machine and hoses and leave gun submerged in solvent pail.
