The surface must be thoroughly dry. Moisture can turn the sealer white and cloudy, stop adhesion, and cause delamination.\u003c\/li\u003e\n\u003cli\u003eExisting concrete: pressure clean, preferably above 2000 psi. Remove loose cement and efflorescence with hydrochloric acid at about 9 parts water to 1 part acid. The acid ratio can change with the surface. Do not let the acid dry on the concrete. Rinse with fresh water and let the surface dry completely. Do not acid wash a surface that has been mechanically ground.\u003c\/li\u003e\n\u003cli\u003eDo not apply below 10°C or above 35°C, or if the temperature will fall below 10°C while the coating is drying.
