DECRA-SEAL™ W/B

Non-Yellowing Sealer for Decorative Concrete

DESCRIPTION
DECRA-SEAL W/B is a non-yellowing, high solids, liquid sealer for decorative concrete. The product is clear, transparent and easy-to-apply. DECRA-SEAL W/B also offers greatly improved chemical resistance when compared to standard acrylic only based curing and sealing compounds. The product has been formulated to seal and protect decorative colored concrete by producing a hard, yet flexible, clear film. DECRA-SEAL W/B meets the very strict maximum VOC content limits of 200 g/L for sealers as required by certain California Air Pollution Control Districts, as well as the 400 g/L VOC maximum required by the U.S. EPA Architectural Coatings Rule. This product is specifically formulated for the residential decorative concrete market.

USES
DECRA-SEAL W/B is designed for various applications, including exterior concrete surfaces, driveways, patios, swimming pool areas and exposed aggregate, as well as any exterior surface where protection and sealing of concrete is desired. The use of DECRA-SEAL W/B on any exterior concrete surface provides a durable, long-lasting finish that has improved resistance to chemicals, oil, grease, de-icing salts and abrasions.

FEATURES AND BENEFITS

VOC compliant … meets both the California Air Pollution Control District and U.S. EPA Architectural Coatings Rule requirements Provides a totally clear membrane that will not yellow Seals all concrete surfaces providing a glossy appearance and easier clean up Dustproofs concrete with a tough, durable film Helps minimize spalling of exterior concrete Provides good blush resistance in damp areas Applies easily Provides a clear, tough film, which improves abrasion and stain resistance Offers improved resistance to rain, sun, freezing temperatures, most acids and industrial chemicals, oil, grease, de-icing salts, cleaning agents (except aromatic solvents), caustics, airborne soot, dust and other pollutants Seals and enhances the beauty of many concrete surfaces for years Can be recoated after thorough surface cleaning to restore original beauty Dried film is USDA accepted

** Low concrete or air temperatures and/or high relative humidity will extend drying times.

APPLICATION
Mixing … For optimum performance, gentle mixing or agitation is recommended. CAUTION: DO NOT MIX EXCESSIVELY.

Surface Preparation…Existing Concrete: Concrete surface must be clean and dry with all chemical form agents, stains, oil, grease, dust and dirt removed prior to application. New Stamped Concrete: Surface must be clean and free from all powdered release agent residue. CAUTION: If a liquid compound other than W. R. MEADOWS CS-309™ series or VOCOMP® series products have been used, do not apply DECRA-SEAL W/B until all traces of the compound have been completely removed and the surface is clean and dry. We recommend ULTRITE® DEGREASER from W. R. MEADOWS for removal and cleaning.

Application Method…A typical commercial sprayer provides an easy, economical method of application. DECRA-SEAL W/B should be sprayed with an 8001 tip that produces a flow of 1/10 of one gallon per minute. Spray on in a fine, fog pattern, without spurts or dribbles, to form a thin, continuous film. AVOID PUDDLING in low areas. If puddles occur, brush or roll them out. For added protection and a greater sheen on concrete, we recommend two coats of DECRA-SEAL W/B be applied at right angles. Additional coats may be applied after the first coat has thoroughly dried.

Drying Time…DECRA-SEAL W/B dries quickly. Drying times may be extended depending on application rate, temperature, humidity and project conditions. Restrict foot traffic for at least six hours. Twelve hours is preferred.

Clean Up…While DECRA-SEAL W/B is still wet, equipment may be cleaned with soap and water. Once dried, the material may be removed with a solvent, such as Xylene or Toluene.

PRECAUTIONS
KEEP FROM FREEZING. Do not dilute. Do not apply when air, material and surface temperatures are expected to fall below 40°F (4°C) within four hours of completed application. DO NOT MIX "WATER-BASE" COMPOUNDS WITH ANY COMPOUND CONTAINING SOLVENT.

DECRA-SEAL W/B is designed for colored concrete, but mottling may occur. Do not use on dense or non-porous surfaces, i.e., brick, stone, etc. For other specifications, secure the approval of the paint or resilient flooring manufacturer before applying product. The specifier and user shall determine the suitability and assume all responsibilities therewith.

HEALTH HAZARDS
Direct contact may result in mild irritation. Inhalation may cause irritation of the respiratory tract. Refer to Material Safety Data Sheet for complete health and safety information.
