DIRECTIONS
Surface to be treated should be free of dirt, oil, grease and other contaminants. The cleaner the surface, the more effective RustBlast will work.
Scrape off any loose rust, mill scale, paint, etc. and clean with a WATER-BASED cleaner/degreaser. FOR BEST
RESULTS, Use KBS AquaKlean. Avoid any solvent-based cleaners as they can leave an invisible residue.
Liberally apply RustBlast FULL-STRENGTH to a DRY surface using a spray bottle, brush, roller, or backpack
sprayer for larger applications.
Re-apply often and as needed to keep the surface wet for a minimum of 10 minutes for smooth or lightly rusted
surfaces, 20-40 minutes for moderately rusted surfaces and 1-2 hours for heavily rusted or corroded
surfaces. DO NOT allow surface to dry.
After treatment, rinse thoroughly with water and then allow surface to dry completely.
For removal of light corrosion or etching of non-ferrous metals (such as aluminium, brass, copper), prepare
surface as above and apply RustBlast for 10-20 minutes then rinse thoroughly with water and allow
surface to dry completely.
NOTE: Once dry, RustBlast may leave a slight powder residue which is the zinc phosphate coating. Items treated
with RustBlast can remain uncoated for up to 30 days depending on environmental conditions. Ideal working
temperature 13-27˚C.
QUESTIONS & ANSWERS
Q. Why is there a white powdery substance left over after I rinse off the RustBlast?
A. The slight white powdery residue is Zinc Phosphate and RustBlast leaves that behind because it aids in
adhesion of coatings such as RustSeal.
Q. Can I use RustBlast when applying paints other then KBS RustSeal?
A. Yes. RustBlast works well as a metal prep and etch for most paints.
Q. Can I use RustBlast to remove rust from equipment and tools?
A. Yes. Soak the tool or equipment for 30 minutes to 24 hours and rinse it off with water using a scotch brite pad. You will be left with rust free tools and equipment.
Q. Do I really have to rinse off the RustBlast with water?
A. Yes. It is important to rinse before the RustBlast dries to avoid a heavy layer of Zinc Phosphate.
