Details
Use TRU™ Self-Leveling for high performance floor topping, underlayment and resurfacing projects. TRU™ Self-Leveling is ideal for projects that need long flow life and working time while achieving high early strength. TRU™ Self-Leveling cures to a light off-white color ideal for stained, dyed, or integrally colored floors and decorative embedded aggregate flooring. TRU™ also grinds and polishes well, making it ideal for polished decorative floors.
Applications:
Use Rapid Set® TRU™ Self Leveling when a high-quality and fast floor topping, resurfacer, or underlayment is required. TRU™ is ideal for projects that need long flow life and working time while achieving high early strength. TRU™ cures to a light off-white color ideal for floors that are stained, integrally colored, and decorative embedded aggregate flooring. It also grinds and polishes exceedingly well, making it ideal for polished decorative floors.
TRU™ is an innovative, high performance floor material with proven success on diverse construction projects.
Description:
Rapid Set® TRU™ Self-Leveling is an advanced hydraulic cement based, self-leveling topping, resurfacer, and underlayment that can be used both indoors and outdoors. TRU™ rapidly levels, maintains workability for 30 minutes, and produces a smooth, strong surface with high bond strength. TRU™ is ready for foot traffic in 2 - 3 hours and ready for coatings in about 12 hours. TRU™ Self-Leveling is a crack resistant, durable, one-component system and won't deteriorate in damp conditions.

Surface Preparation:
Substrate must be clean, sound, and free of oil, curing compound, dust, mastic and other bond-breakers. Surface should be ICRI CSP 3 - 5. Mechanical methods of surface preparation such as shotblasting are preferred. Acid etching the substrate is not recommended. Surface must be dry, have a minimum temperature of 50°F and be properly primed.
Prime:
Apply Rapid Set® Acrylic Primer to the prepared concrete substrate following the product specifications. When placing TRU™ as a decorative topping, epoxy with sand broadcast to refusal is the preferred method of priming. To use this method, follow the "Prime the Substrate" section in the Technical Bulletin for TRU™ Floor Polishing.
Mix:
Add one bag of TRU™ to 4.5 quarts (4.3 liters) of potable water. Mix 3 - 5 minutes until the mixture is smooth and lump free. Avoid mixers that entrap large amounts of air. Mixed TRU™ should be used within 30 minutes at 70°F. Maintain material temperature above 50°F.
Placing:
Arrange work area to permit continuous placement without cold joints. Pour or pump the TRU™ onto the prepared and primed substrate with a minimum thickness of 1/8? over the highest point. TRU™ will flow and level out within its 15-minute flow life. Use a gauge rake, spreader or other tools to coax the material into place as required. Use a porcupine-type roller to remove any entrapped air.
For thicknesses greater than 1.5", extend each 50-lb. bag of TRU™ with 25 lbs. of clean, dry 3/8" pea gravel. Place the extended material to ½" below desired floor level and then place neat TRU™ for the final ½" within 24 hours.
Cure:
No wet curing is required under normal conditions at 70°F. If used in exterior applications apply a fine water mist to the newly hardened surface of TRU™ 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 epoxy can be applied per the manufacturer's recommendations after 12 hours.
Yield & Packaging:
TRU™ is available in 23 kg (50-lb.) polyethylene-lined bags. Yield is 0.45 cf per 50-lb. bag. Coverage is 22 -24 sf at ¼" thickness and 11-12 sf at ½" thickness for flat surfaces.
