The PC Products PC-Concrete is a two-part epoxy adhesive paste used to fill and repair cracks in concrete and to anchor threaded rods, bolts, and dowels into concrete, grout-filled block, and unreinforced masonry in indoor and outdoor applications. The epoxy is made from a high-tack paste that resists moisture for application in damp environments and can be used in vertical applications. After maximum curing, it creates a high-strength bond that will hold during expansion and contraction of concrete. The paste can be painted, stained, and machined, and is nontoxic and nonconductive after it has been cured. PC-Concrete meets American Society for Testing and Materials International (ASTM) C881-99 standards.SpecificationsApplication temperature range35 to 115 degrees FService temperature range-20 to +115 degrees FWorking time20 minutes (at 75 degrees F)Time until cured4 hours (at 75 degrees, also dependent on humidity and application size)Mix ratio1:1 Protective Coating Company manufactures products to repair and restore various materials, including wood and concrete.
