Rapid Set Tru Self Leveling

DESCRIPTION: 

Rapid Set TRU SELF-LEVELING is an advanced, professional grade, hydraulic cement-based, architectural topping and resurfacer. It can be ground and polished to a high-gloss appearance. TRU SELF-LEVELING rapidly levels, has long flow life and maintains workability for 20 minutes, is ready for foot traffic in 2 to 3 hours, produces a smooth, strong surface, has high-bond strength, and ready for coatings in 12 hours. As an interior and exterior product, it is durable in wet or dry conditions. TRU SELF-LEVELING is available in natural and gray.

USES: 

Use TRU SELF-LEVELING for finished floors in commercial, institutional and recreational facilities.

ENVIRONMENTAL ADVANTAGES: 

Use TRU SELF-LEVELING 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.

APPLICATION: 

Apply TRU SELF-LEVELING when a high quality, fast, polishable topping is required. TRU SELF-LEVELING is ideal for projects that need long flow life and working time while achieving high early strength. A customized appearance can be achieved by adding integral colors and/or decorative aggregate. Protective coatings, sealers or epoxies can be applied per the manufacturer’s recommendations after 12 hours.

SURFACE PREPARATION: 

Substrate must be clean, sound concrete that is free of gypsum compounds and all materials that may inhibit bond such as: oil, curing compound, dust, mastic, bond breakers, and other surface contaminants. Mechanical methods of surface preparation such as shot blasting are preferred. Surface must be ICRI CSP 3 to 5. Acid etching the substrate is not recommended. Surface must be dry and be properly primed. Surface and ambient temperatures must be between 50°F and 90°F (10°C and 32°C).

PRIMING: 

Use a Rapid Set® TXP™ epoxy primer with sand broadcast to refusal. Follow all product specifications and instructions.

MIXING: 

Add one bag of TRU SELF-LEVELING to 4.0 to 4.5 quarts (3.8 to 4.3 L) of clean, potable water. Mix 3 to 5 minutes until the mixture is smooth and lump-free. Avoid mixers that entrap large amounts of air. Mixed TRU SELF-LEVELING should be used within 20 minutes at 70°F (21°C). Maintain material temperature between 60°F and 80°F (16°C and 27°C). Do not exceed 4.5 quarts (4.3 L) per bag.

PLACEMENT: 

Arrange work area to permit continuous placement without cold joints. Pour or pump the TRU SELF-LEVELING onto the prepared and primed substrate with a minimum thickness of 1/8" (3 mm) over the highest point. A minimum of 3/8" thickness (10 mm) is required for polished flooring. Please refer to CTS Technical Bulletins for more information. All existing joints and moving cracks must be honored up through the topping. TRU SELF-LEVELING will flow and level out within its 15 minute flow life. Use a gauge rake to coax the material into place as required. Use a Rapid Set® Spiked Roller to remove any entrapped air. For thicknesses greater than 1.5" (3.8 cm), extend each 50-lb (22.7-kg) bag of TRU SELF-LEVELING with 25 lbs (11.3 kg) of clean, dry 3/8" (10 mm) pea gravel.

CURING: 

No wet curing is required under normal conditions at 70°F (21°C). If used in exterior applications, apply a fine water mist to the newly hardened surface of TRU SELF-LEVELING as soon as it can be done without marring the surface, and continue until one hour after final set. Avoid excessively dry, windy, hot or sunny conditions.

Adhesives, thin set or paint can be applied after 6 hours. If used as a topping that will receive traffic, a high-quality sealer or coating can be applied per the manufacturer’s recommendations after 12 hours.

POLISHING: 

TRU SELF-LEVELING may be polished wet or dry after 24 hours at normal conditions. TRU SELF-LEVELING grinds and polishes much like concrete and can achieve a very high gloss and Distinctness-of-Image (DOI) due to its high density and low polymer content. Polishing any topping requires a high degree of experience and craftsmanship. Contact CTS Cement for a list of preferred installers.

COLD WEATHER: 

Environmental and material temperatures below 70°F (21°C) may delay setting time and reduce the rate of strength gain. Lower temperatures will have a more pronounced effect. Thinner sections will be more significantly affected. To compensate for cold temperatures, keep material warm, use heated mix water, and follow ACI 306 Procedures for Cold Weather Concreting.

WARM WEATHER: 

Environmental and material temperatures above 70°F (21°C) may speed setting time and increase the rate of strength gain. Higher temperatures will have a more pronounced effect. To compensate for warm temperatures, keep material cool, use chilled mix water and follow ACI 305 Procedures for Hot Weather Concreting.

YIELD & PACKAGING: 

TRU SELF-LEVELING is available in 50-lb (22.7-kg) polyethylene-lined bags. Yield is 0.45 ft3 per 50-lb (22.7-kg) bag. Coverage is 15 ft2 to 16 ft2 (1.4 m2 to 1.5 m2) at 3/8" (10 mm) thickness and 11 ft2 to 12 ft2 (1.02 m² to 1.11 m²) at 1/2" (13 mm) thickness for flat surfaces.

SHELF LIFE: 

TRU SELF-LEVELING has a shelf life of 12 months when stored properly in a dry location, protected from moisture, out of direct sunlight, and in an undamaged package.
