Description
Rapid Set® WUNDERFIXX® is a high-performance, gray concrete smoothing compound. WUNDERFIXX is a blend of Rapid Set hydraulic cement, high-performance polymers, self-curing technology (SCT) and finely ground aggregate. Mix WUNDERFIXX with water to produce a workable, easy-to-apply mixture with excellent bonding characteristics. Trowel apply WUNDERFIXX to achieve a smooth and uniform finish. After applying, WUNDERFIXX may be sanded within 24 hours to achieve an ultra-smooth finish.
Use WUNDERFIXX for cosmetic patching, detailing and smoothing on tilt-up panels, precast, formed work, concrete block and other concrete and masonry surfaces. Durable in wet environments, it is suitable for both interior and exterior applications. WUNDERFIXX may be used on vertical, overhead and non-wearing horizontal surfaces.
Use WUNDERFIXX to reduce your carbon footprint and lower your environmental impact. Production of Rapid Set cement emits far less CO2 than portland cement. Contact your representative for LEED values and environmental information.
Apply WUNDERFIXX in thicknesses from skim coat to 1/2" (1.3 cm). For thicker applications, use appropriate Rapid Set® repair products. Consult your CTS Cement Representative for more information and training.
Application surface must be clean, sound concrete that is free from any materials that may inhibit bond, such as form release, oil, curing compound, acid, dirt and loose debris. Apply WUNDERFIXX to a surface that is dry or saturated with no standing water. A test area should be applied to determine suitability in the repair environment.
The use of a drill-mounted mixing paddle is recommended. Organize work so that personnel and equipment are in place before mixing. Use clean, potable water. WUNDERFIXX may be mixed using 6 to 8 quarts (5.7 L to 7.6 L) per 50-lb (22.7-kg) bag. Use less water to achieve higher strengths. Do not exceed 8 quarts (7.6 L) of water per bag. For increased fluidity and workability, use Rapid Set® FLOW Control plasticizing admixture from the Rapid Set® Concrete Pharmacy®. Place the desired quantity of mix water into the mixing container. While the mixer is running, add WUNDERFIXX. Mix for the minimum amount of time required to achieve a lump-free, uniform consistency. Do not retemper.
At time of installation, the surface and ambient temperatures must be between 50°F and 90°F (10°C and 32°C). WUNDERFIXX has a working time of 30 minutes at a temperature of 70°F (21°C). Once in place, as the material becomes stiff (typically within 10 to 20 minutes), use a trowel to shave or cut the excess material to the desired shape. Material can be sanded, primed and painted the same day.
WUNDERFIXX does not require water curing or curing compound under moderate conditions at 70°F (21°C). In dry, windy or hot conditions, mist with water to maintain a continuously wet surface until the product has achieved sufficient strength.
