Extended Information:
COVERAGE 75 sq.ft./gal. (7.4m2/l) (first coat) 100 sq.ft./gal. (9.8m2/l) (second coat) Coverage may change depending on porosity and application method. SURFACE PREPARATION Surfaces must be clean, dry, sound and free of dirt, greases, soap, and other contaminants. New masonry must cure for at least 30 days before applying WaterTite Mold & Mildew-Proof Waterproofing Paint. Salting or efflorescence (a white powdery deposit oft en found on walls) must be removed with WaterTite®
Etch and Cleaner or a similar product. Follow manufacturer’s
directions and safety precautions. Rinse the surface thoroughly
with fresh water. Remove all existing mold and mildew. Use a
solution of 1 cup household bleach per gallon of water or
use a mildew cleaner or Jomax®Mold & Mildew Stain Remover. For commercial buildings, follow appropriate guidelines for mold removal.
If there is a concern about mold and mildew behind walls, underneath flooring, in ventilation systems or other unseen areas, contact a professional who specializes in mold and mildew remediation). Remove mold and mildew on exterior surfaces with Jomax® House Cleaner and Mildew Killer.
Previously Painted Surfaces-It can be used over previously painted, non-glossy surfaces; however its waterproofing ability is then dependent upon the integrity of the previous coating. For best results, remove as much of the old coating as possible by manually scraping the surface, followed by thorough wire rushing. A belt sander with a 50 grit sanding belt is also effective. Exterior surfaces should be power washed or abrasive blasted to remove all loose and scaling paint and cement.
WARNING!
If you scrape, sand or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH-Approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the National Lead Information Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead.
Patching Water Leaks and Cracks-All holes and cracks,
especially active water leaks, must be patched with WaterTite Polyurethane Sealant or a similar product. Follow manufacturer’s directions for dry time, etc.
MIXING
Mix thoroughly to ensure any settled pigment is re-dispersed. DO NOT THIN. APPLICATION Use in a well ventilated area. Extinguish all pilot lights and other sources of flames or ignition. Remove electrical equipment from the area. Stir or mix thoroughly before and during application. DO NOT THIN. Apply only when air, material, and surface temperatures are between 50-90ºF (10-32ºC) and the relative humidity is or less than 85%. Liberally apply the first coat using a thick polyester bristle brush, or by rolling a small section (3x3 foot) and then using a brush to work the coating into the pores of the masonry. Apply as much paint as necessary to produce a continuous, pinhole free film. Use a 1” nap roller cover for unpainted, porous surfaces or a ¾” nap roller cover for smooth or previously painted surfaces. The second coat can be brushed or rolled.
Color/Tinting - WaterTite Mold & Mildew-Proof
Waterproofing Paint tints easily to beige, blue, and gray (see back of container label). It can also be tinted to other off-white and pastel tones. Maximum amount of tint should not exceed 1.5 ounces (30 ml) per gallon. Mix on a mechanical shaker for 7-9 minutes or use a drill motor. Multiple containers of tinted paint should be boxed (intermixed) to ensure color uniformity. DRY TIME Dries to the touch in 1 hour. Allow the first coat to dry a minimum of 4 hours before applying the second coat. After the second coat has dried, inspect the surface for pinholes. Reapply additional paint to those areas as necessary. After reaching its full cure in 7-14 days (slightly longer if tinted) WaterTite will stop up to 34 psi of water pressure. Do not apply if heavy rain is expected with 24 hours.
CLEAN-UP
Wipe up fresh spills and drips with a rag and paint thinner. To minimize solvent odors, use odorless mineral spirits and clean application tools outside of the work area.
