Bonstone Crack Repair 28

Crack Repair 28 is a medium viscosity epoxy cartridge system, which is generally used for injecting into horizontal wide cracks in stone. On vertical applications a capping compound should be used to seal the crack.  We strongly suggest using a dual cartridge applicator gun when using this product. It is a little thicker in viscosity than the Crack Repair 31, but still flows. Crack Repair 28 works great for bonding new concrete to existing concrete and injection into wider masonry and stone cracks. Cracks must be capped for vertical applications. Applications Bonding new concrete to existing concrete Injection for wider cracks Product Information Mix Ratio = 2:1 by volumeSet Time = 3 hrs @ 75°F Structural grade epoxy for injection Meets ASTM C-881, Types I, II, IV, V; Class C, Grade 2 Can be tinted with Liquid Tints Use with Small Long Nozzle For best results we suggest using Manual Dual Cartridge Gun
