SHARPSHOT® has been a proven blasting abrasive and roofing granule for over 25 years. It is an air-cooled and crushed iron silicate product. Our cooling and crushing process creates a sub-angular, black (dull, not glassy), hard, cubical, durable granule and an aggressive abrasive.

SHARPSHOT® applications include:

blasting removal of paint and rust from ships, bridges, tanks, etc.; subsea waterjet cutting (e.g., abandonment and decommissioning); light paint and rust removal in new construction surface preparation; antique restoration; automobile body paint and rust removal; plastic and wood surface preparation; felt and polyester roll roofing; tab roofing shingles; weighting for artifical turf, and dense concrete used for nuclear shielding; filler in the manufacture of synthetic marble and granite countertops (black); aggregate for architectural concrete walls and sidewalks; in road applications as a base aggregate in fiber mat roads, for non-skid overlays, and for removal of old stripes and lines on highway or parking lot surfaces.

SHARPSHOT® spent abrasives are recycled for use in the manufacture of Portland cement; and SHARPSHOT®, blended with  BLASTOX®, can render lead paint non-toxic.
