Moisture Vapor Control Coating & Flooring System

Description

KEY #780 is a 100% solids semi-rigid epoxy joint filler used to protect contraction/control joints (saw cut joints) in concrete slabs on grade or repair existing damaged joints. Key #780 absorbs the impact and shock of heavy loads and steel wheeled traffic, preventing erosion of control joint edges.
