When used as a crack sealer: Use grinder to remove any loose concrete. Smooth edges of crack. Plow crack out with a air blower. Substrate must be free of grease, standing water and other contaminants that may impede adhesion. Always check the surface for any bond inhibitors prior to application.

As a Mastic: Apply directly to substrate. Using a putty knife, smooth to desired finish. As a crack filler: Apply epoxy directly into crack until level with the floor. Allow to dry 2 hours before top-coating. When being used in conjunction with BGFL76: Use a putty knife spread Flex Guard-FM over the crack to cap it in epoxy leaving a 3-inch space for epoxy ports to be applied. Apply Flex Guard-FM to the outside edge of the port. No Flex Guard-FM should block the center passage of the port.
