Rust Grip® Applications
Application
Although Rust Grip® can be applied by non-professionals, we recommend using a certified applicator.
Preparation:
- 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)
Temperature:
- 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
Precautions:
- 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
Limitations:
- 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
