MM-80P is a two-component, 100% solids content epoxy joint filler. When cured, MM-80P is a gray, semi-rigid (hard but slightly resilient) filler with a Shore hardness of A90-95.
MM-80P was developed to fill and protect joints in industrial concrete floors that are subject to hard wheeled material handling traffic and heavy loads. Its primary function is to support such traffic and protect joint edges from spalling. MM-80P is designed for use in areas where final temperatures are from 40F (10C) to +120F (49C). It is also ideal for joint and crack repair.
MM-80P should be installed full joint depth in saw-cut control joints (or 2″ min. in joints where depth exceeds 2″) per PCA and ACI guidelines. In construction (formed) joints that are not saw-cut, MM-80P should be installed 2″ deep. If shrinkage crack is excessive and needs to be “choked off,” it may be sealed with clean, dry silica sand.
