SURFACE PREPARATION: The bare masonry surface to be coated must be clean and free from dirt, efflorescence (white powdery deposits), mildew, form release agents or any other surface contaminates that could affect proper adhesion and performance. Concrete must cure a minimum of 14 days before coating, or have a pH of 13 or lower. Efflorescence may be removed by treating the area with a diluted solution of muriatic acid following all label application and safety directions. Any active mildew spores growing on the surface must be removed by scrubbing the area with a mixture of 1 part household bleach* mixed with 3 parts water. Rinse well with clean water following bleach wash. Always wear eye protection devices, rubber gloves and protective clothing when working with either bleach or acid solutions. Patch all holes, joints and large cracks (greater than 1/8”) in the masonry surface with hydraulic cement. Hairline cracks and joints smaller than1/8” may be sealed with concrete sealant or caulk. Do not apply sealant if visible water is leaking. If water is present in joint & cracks, use concrete sealant or caulk as directed.

APPLICATION: Stir Masonry Waterproofer thoroughly before and periodically during application. Best results will be obtained by applying Masonry Waterproofer directly on bare masonry surfaces by a stiff synthetic filament brush or a ½” to ¾” nap roller cover. If rolled on bare masonry, it is important to back brush the coating to work it into the substrate. Make sure that all holes and voids have been filled with the application of this product. The application of two unthinned coats provides the best result. Paint only when surface and air temperatures are between 50 and 90 degrees Fahrenheit.

NOTE – Insl-x® WaterBlock® Acrylic Masonry Waterproofer may be spray applied with either an airless texture spray pump or a hopper spray gun. For additional spray information, ask your local Insl-x® Representative.

IMPORTANT: If leaking or seepage is present after two coats, it indicates that pores or pinholes are still open. Apply an additional coat paying special attention to filling these voids and pinholes.

LIMITATIONS: Paint only when surface and air temperatures are between 50 ° (10 °C) and 90 °F (32.2 °C). Do not apply if temperature is within 5 ° of dew point. Should not be used on floors.
