Slant shear tests meet and exceed requirements of ASTM C 882. Allow 10 to 15 minutes open time to apply PRODUCT #304, prior to placement of fresh concrete, when testing slant shear at 40°F (4°C).


All surfaces to receive PRODUCT #304 must be free of dirt, grease, curing compound, liquid contaminants, heavy laitance and soft or deteriorated concrete. It is recommended that abrasive blasting, water blasting or acid etching with a 10% solution of commercial muriatic acid be utilized for surface preparation. Vacuum all areas prior to application to remove fine particles of cement or sand. Surface must be sound.


Combine two parts by volume of "A" Component with one part by volume of "B" Component (mixing ratio is 2:1). For best results, mix entire unit. The blend should be thoroughly mixed for at least three minutes with a low speed 1/2" electric drill and Epoxy.com Mixing Paddle. If used as a mortar, introduce the PRODUCT #75 Filler slowly while mixing to assure proper aggregate saturation.
