615 Exterior Concrete Patch Thoroughly broom-sweep and vacuum the area to be resurfaced to remove any fine dust or dirt. Clean debris out of expansion joints, and then tape or mask the joints off to prevent the HENRY 615 from filling them. Use a lawn edger to clean around walks or driveways, as well as around planter boxes and landscaped areas. Substrates must be dry for a successful installation. Substrate and ambient temperatures must be a minimum of 50°F (10°C) for the installation of HENRY products.

Mix the HENRY 615 with water first, and then add 1 part by volume of aggregate, mixing until the aggregate is completely coated. Do not use sand. If aggregate is wet, reduce the amount of water to avoid over watering.
