SAMSON OCEANFRONT PARK <br />CITY OF SUNNY ISLES <br />TECHNICAL SPECIFICATIONS <br />CONCRETE REPAIR MORTARS 033123-3 <br /> <br />Dampen substrate to fill concrete pores with water. Remove ponding, glistening, or surface water (saturated surface <br />dry). <br />Apply scrub coat of repair mortar into substrate to ensure intimate contact and establish bond. <br />Apply mortar while scrub coat is wet. Consolidate and trowel to the desired finish, with a minimum thickness of 1/4 <br />inch. <br />For application depths greater than 2 inches, apply in successive lifts, per manufacturer’s instructions. <br />Apply first lift and scratch surface to promote mechanical bond to subsequent lifts. <br />Apply second lift as soon as initial lift has hardened sufficiently to receive additional material. A scrub coat is not <br />required between successive lifts. <br />If more than three lifts of material are required, allow at least 24 hours of curing between each third lift and the next <br />application. <br />Curing <br />Keep surface damp for 48 hours with continuous light water-fogging. <br />If no coating or sealer is to be applied, a water-based curing compound meeting ASTM standard C309 may be used. <br />Do not use solvent-based curing compounds. <br />Cleaning: Remove excess material before material cures. If material has cured, remove using mechanical methods <br />which will not damage substrate. <br /> <br />END OF SECTION <br />
