Sand-blast/water-blast or brush tool the area to remove all the paint and scarify the surface to open the pores and the capillaries of the concrete where necessary. U-groove all cracks and cold joints 1/2 inch – 1 inch. Remove all loose concrete and any other contaminants. Apply Crystalline*A* insta-plug where necessary to stop any active water flow. Apply Crystalline*B* to the U-grooved cracks and joins, overlapping 6 inches on each side.
Wait approximately 30 – 60 minutes or until the coating does not stick to the finger. (Drying time depends on ambient temperature) Apply a second coat of Crystalline*B* in a perpendicular direction of the first coat (First coat-vertical, Second coat-horizontal). Apply one coat of Crystalline C/D over the Crystalline*B* when B is dry to the touch; this allows Crystalline*B* to remain hydrated during the 24 hour curing process. All work areas will be ready for your painting contractor after completion and curing. (Recommended to use a breathable emulsion type paint over Crystalline products).
