Precast 80

Fast-drying premium reactive form release

Precast 80 is a chemically reactive, mineral oil-based release agent designed for precast and shop use applications. It effectively prevents concrete from bonding to formwork, does not contain diesel, waxes, or silicones, and is specifically engineered for fast drying.

  • Enhances formwork release
  • Minimizes concrete buildup on formwork
  • Reduces the need for formwork cleaning
  • Protects formwork against rust
  • Leaves no residues, stains, or discolorations
  • Does not inhibit the bonding of coatings or toppings

  • Ensure form surfaces are clean of dirt, rust, scale, and concrete buildup before application.
  • Apply Precast 80 using a spray with an atomizing or misting tip to ensure a thin, uniform film, enhancing product performance and efficiency.
  • Recommended coverage ranges from 1000 to 2000 sq ft/gal for steel, fiberglass, and HDO plywood. Actual rates may vary.
  • Remove any excess material or puddles with a squeegee and absorbent rags.
