Metzger McGuire MM-80 Semi-Rigid Epoxy Concrete Joint Filler is a two-component, 100% solids content epoxy joint filler designed to fill, protect, and repair joints and cracks in industrial concrete floors that are subject to hard, heavy wheeled traffic from carts, forklifts, and other vehicles handling heavy loads. Designed for use in areas where final temperatures are from 40˚F (10˚C) to +120˚F(49˚C).


When cured, MM-80 is a gray, semi-rigid (hard but slightly resilient) filler with a Shore hardness of A90-95. It yields sufficient rigidity to support loads crossing joints, protecting edges from spalling. It also offers sufficient resiliency to prevent brittleness throughout the floor’s life.

MM-80 exhibits low range tensile and adhesive strengths, which are characteristics necessary to allow the joints to open as the concrete shrinkage progresses.

MM-80 is the joint filler upon which ACI and PCA standards are based.
