METZGER MCGUIRE – JOINT FILLERS
Metzger Mcguire MM80 Epoxy Based Joint Filler
Composition
MM-80 is a 100% solids, two component, heavy duty semi-rigid epoxy joint filler designed to fill and protect contraction and construction joints in industrial concrete floors. The industry’s first semi-rigid joint filler and still widely known as the “industry standard” in floor joint protection.
Shore A Hardness: A90-95
Basic Use
MM-80 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. MM-80 is designed for use in areas where final temperatures are from 40˚F (10˚C) to +120˚F (49˚C). It is also ideal for joint and crack repair.
Metzger Mcguire Armor-hard
Composition
Armor-Hard is a 100% solids, two component structural epoxy mortar kit intended for use in the structural repair or joints, cracks and other surface defects in industrial concrete floors. Armor-Hard Kit comes with a specially engineered aggregate blend designed for easy troweling/finishing.
Compressive Strength: 10,500 psi
Related Products/Versions
ARMOR-HARD is available in two primary versions: ARMOR-HARD Liquid or Kit – Early Set properties (faster than standard structural epoxies, slower than EXTREME), use limited to temperatures of 50˚F +. ARMOR-HARD EXTREME Liquid or Kit – Quick set properties, multiple temperature applications.
Typical Use
As a mortar
• Spall repair/rebuilding of joint shoulders
• As a topping for delaminated slabs
• Fill in holes, gouges, ruts, popouts
• Repair broken slab panel corners
