Mixed to a workable mortar-like consistency, Concremate sets in 30 minutes and sets harder than concrete in 28 days. An expanding element in Concremate offsets drying shrinkage (often a problem in similar products) which causes it to grip embedded items and surrounding material with bulldog tenacity. Expansion is 1/8% Concremate quickly and firmly embeds objects like hand-rails, bolts, brackets or fixtures in concrete, stone, tile, plaster and terrazzo. Bond is strong and durable and defies severe strain, stress and vibration. Use as high pressure grout. Concremate makes quick work of repairing holes and cracks in walls, ceilings and floors. A patch or plug of Concremate locks itself into place by expanding within the void and will not crack or let go when subjected to normal heat or pressure. Must be able to expand on drying.
