Quadex QM-1s Restore is supplied in 60 lb. (27 kg) polyethylene lined bags.


One 60 lb. (27 kg) bag of Quadex QM-1s Restore yields approximately .54 cu. ft. and will cover 12.5 sq. ft. at a 1/2 in. thickness.


Prepare the surface to be restored by removing unsound concrete, dirt, dust, oil, and other debris using high pressure (3500 psi) water blasting. Air blast excess water with an oil free air compressor. This will provide a clean, damp surface to allow for a good bond.

Use approximately 0.7 to 0.9 gallons of water per 60 lb. bag of Quadex QM-1s Restore. First add water to mixer. Start mixer motor and add Quadex QM-1s Restore until mortar is completely mixed.

Apply Quadex QM-1s Restore by low-pressure spraying on vertical or overhead surfaces to a monolithic thickness of 1/2 to 3 inches in one pass. Trowel to a smooth surface.


Cure in accordance with current ACI recommendations. Use a two coat application of a manufacturer approved water based curing compound.
