DESCRIPTION: BRUSH-N-SEAL is a one part polymer modified, decorative, cementitious and waterproof coating that is designed for use on concrete and masonry surfaces. BRUSH-N-SEAL is specifically formulated for use as a waterproof coating that will resist both positive and negative hydrostatic pressure.

• Providing a protective, decorative textured finish over concrete and masonry surfaces
• Providing a breathable coating for vertical end overhead applications on interior and exterior surfaces, above and below grade
• Waterproofing brick, block and porous stone
• Eliminating rubbing by filling in voids, pit marks and small holes
• For use in basements, tunnels, cisterns, reservoirs, foundations and machinery pits

• Excellent bond strength for superior adhesion
• Excellent freeze/thaw resistance
• Thermal expansion similar to standard concrete
• Resistant to de-icing salts and water
• Excellent waterproofing properties
• Resistant to ultraviolet light

PACKAGING: BRUSH-N-SEAL is available in 10, 30 and 50 pound pails and a 50 pound bag.

PRIMING: The use of a primer before the application of BRUSH-N-SEAL is not necessary.

WORKING TIME: The working time of BRUSH-N-SEAL is approximately one hour at 70ºF (21ºC). Application time is dependent on temperature (shorter at high temperatures and long at low temperatures).

SURFACE PREPARATION: The existing concrete surface must be clean and sound. Remove all unsound concrete, paint, dirt, grease, oil, surface coatings, laitance and any other bond-inhibiting material from the surface. This may be achieved by high-pressure water washing or by wire brushing and scraping. If any patching is required, patch with BVS MULTI-PATCH LI prior to coating. Also, to stop any active water leaks, use BVS ULTRAPLUG before coating. Non-moving cracks should be routed out and filled with BVS MULTI-PATCH LI prior to coating. BRUSH-N-SEAL will not bridge moving cracks.

COLOR: BRUSH-N-SEAL is available in white and grey.

MIXING: BRUSH-N-SEAL maybe mixed by manual or mechanical means.

Manual mixing; Mix in the original container or use various size buckets and a mixing paddle. Remove the cement from the pail. Add water to the pail and then add the BRUSH-N-SEAL. Mix for 5 minutes or until a batter consistency is achieved. Let stand for 15 minutes and then retemper and add up to 1/2 pint of water if needed.

Mechanical mixing; Mix in a 5 gallon pail using a heavy-duty slow speed drill (400-600 rpm) with a mixing paddle. Pour the measured water into the mixing container and then add the BRUSH-N-SEAL. Pour 1 & 1/2 quarts of water for every 10 lbs. of BRUSH-N-SEAL into a mixing container. While mixing, add 1 unit of BRUSH-N-SEAL. Mix to a consistency of a batter making sure that there are no lumps. Do not mix for more that 2 minutes.

STORAGE CONDITIONS: BRUSH-N-SEAL must be stored between 50ºF (10ºC) and 95ºF (35ºC) in a dry area. Avoid high humidity. The shelf life is one year in the original, unopened container.

APPLICATION: All surfaces should be dampened before beginning the application of BRUSH-N-SEAL. Redampen the surface immediately prior to coating. The surface should be saturated surface dry (SSD) with no puddled water. For most applications use a 6 inch masonry brush; however, for a more decorative finish, use a 6 inch nylon brush. Apply the BRUSH-N-SEAL into the properly prepared surface. Scrub the material into the damp wall in order to fill all pores. Brush strokes should be in one direction (horizontal). If the BRUSH-N-SEAL is not spreading on smoothly and easily, the surface must be redampened. For uniform appearance, finish off with light strokes that blend into the coated areas. Remember to always maintain a wet edge. The first coat should be applied at a thickness of 1/16" (25 mils). After allowing to cure for 24 hours, per-wet the first coat and apply the second coat at a thickness of 1/32" (15 mils). In areas subjected to severe water pressure, the second coat should be applied at a thickness of 1/16" (25 mils). For decorative applications only, two 1/32" (15 mils) coats are allowed.

CURING: If ambient conditions cause premature drying (high temperature, low humidity, strong winds or direct sun light), then a fog spray of water must be used after the BRUSH-N-SEAL has hardened. The fog spray should continue every two hours until the premature drying condition has subsided. For concrete structures that hold water (reservoirs, tanks, etc.) BRUSH-N-SEAL should be allowed to cure for 14 days before refilling with water.

• Apply only on a clean, sound and properly prepared substrate. Surface should be damp but free of standing water (SSD)
• Minimum ambient and surface temperature is 50ºF (10ºC) and rising at the time of the application. Do not apply below 45ºF (7ºC) within 12 hours
• Weepage or leakage should not be present from the substrate at the time of the application
• The maximum application thickness is 1/16" (25 mils) per coat. Greater thickness may result in cracking
• Do not store BRUSH-N-SEAL in areas with high humidity
• Do not retemper or add any admixtures
• Do not apply to traffic bearing substrates

PRECAUTIONS:

• Dispose of waste materials in accordance with federal, state and local regulations
• The use of a dust mask, safety goggles and rubber gloves is recommended
• Caution - contains Portland Cement which is highly caustic
• Contains Free Silica. Do not breath the dust as inhalation may cause delayed lung injury (silicosis) and is a carcinogen
• In case of contact, flush eyes with water. Wash skin with soap and water. Contact a physician
• Keep out of the reach of children
