How to Use


Surfaces to be coated must be free of dust, mildew, mold, dirt, grease, paint, oil, glue size, calcimine, wax, soap and other surface contamination. Clean mold stained surfaces with IAQ Advanced Peroxide Cleaner, or use an EPA registered antimicrobial disinfectant cleaner such as IAQ 2000, IAQ 2500, ShockWave or ShockWave RTU. Patch irregularities with an appropriate patching compound. Efflorescence, a white, powdery, crystal-like deposit visible on masonry surfaces, must be removed. Muriatic acid, used according to manufacturer’s directions, is an effective efflorescence removal agent.


STIR THOROUGHLY BEFORE AND DURING APPLICATION. DO NOT THIN. For best results, use a 5 in. paddle wheel mixer, attached to a 1/2 horsepower, 1/2 inch electric drill. Coat surface only when air and surface temperatures are 50˚F or higher. Apply IAQ 9000 directly on bare masonry. For best waterproofing results, wait for a dry (rain-free) period before application. Apply first coat with a good quality nylon bristle brush, working the waterproofer into the pores of the masonry- avoid excessive brushing. Allow to dry 3 hours before second coat. The second coat may be applied using brush, roller or spray. If leaking is still present after two coats, it indicates that pores or pinholes are still open. These areas should be coated again. Vent outside.


IAQ 9000 may be applied by spray to exterior and interior surfaces, providing certain precautions are followed. Special sprayer equipment is required, please refer to IAQ 9000 Spray Instructions sheet for specific details.


May be tinted to light or pastel shades with alkali-proof universal tinting colors. Use only 25% of color normally recommended. Do not use more than 2 fl. oz. of colorant per gallon. IAQ 9000 is ideal as a finish coat. If desired, a high quality latex paint can be applied after 24 hours for decorative purposes.
