TRU® Self-Leveling


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 20 minutes, and produces a smooth, strong surface with highbond strength. TRU® is ready for foot traffic in 2 to 3 hours and ready for coatings in 12 hours. As an interior and exterior product, TRU® is durable in wet or dry conditions.

SURFACE PREPARATION : Substrate must be clean, sound, and free of oil, curing compound, dust, mastic and other bond breakers. Surface shall be prepared to a minimum profile of ICRI CSP 3. Mechanical methods of surface preparation such as shot blasting are preferred. Acid etching the substrate is not recommended. Surface must be dry, have a minimum temperature of 50°F (10°C) and be properly primed.

Why TRU® Self-Leveling?

  • Specifically designed for polishing and decorative flooring applications
  • Integral colors and aggregates allow for endless design possibilities
  • Grinds and polishes extremely well – very little polymer means crystal clear floors (D.O.I. - Distinctive Of Image)
  • Durable, one-component system
  • 5000 psi (34.5 MPa) in 24 hours
  • Foot traffic in 2-3 hours; coat with epoxy in 12 hours, ready for grinding in 24 hours
  • More consistent flooring appearance (e.g. color, aggregate, polish, shine) and strength than traditional portland cement concrete
  • Longest proven track record in polished overlays backed by years of testing
  • Our floors are compliant with the National Floor Safety Institute (NFSI) and the American National Standard Institute (ANSI)
  • Formulated with Rapid Set Cement

    Use TRU® when a high quality and fast 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 with decorative embedded aggregate flooring. It also grinds and polishes exceedingly well, making it ideal for polished decorative floors.

    PRIME When placing TRU® as a decorative topping, Rapid Set® TXP™ Epoxy Primer with sand broadcast to refusal is the preferred method of priming. When TRU® is not being placed as a finished floor, Rapid Set® Acrylic Primer may be applied to the prepared concrete substrate. Follow all product specifications.

    MIXING Add one bag of Rapid Set® TRU® Self-Leveling to 4.5 quarts (4.3 L) 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 (21°C). Maintain material temperature above 50°F (10°C).

    PLACEMENT 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" (3.2 mm) over the highest point. All existing joints and moving cracks must be honored up through the topping. 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" (3.8 cm), extend each 50-lb (22.7-kg) bag of TRU® with 25 lbs (11.3 kg) of clean, dry 3/8" (9.5 mm) pea gravel.

    CURE 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® 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.

    • Decorative: Designed specifically for polishing and decorative flooring applications
    • Outstanding Clarity & Gloss: Highly polishable due to low polymer content and high density
    • Versatile: Use as a topping, resurfacer or underlayment, incorporate colors and aggregates to create numerous design possibilities
    • Fast Track: Foot traffic in 2 to 3 hours, grind wet or dry, and polish in 24 hours.
    • High Strength: 5000 psi (34.5 MPa) in 24 hours, 6500 psi (44.8 MPa) in 28 days
    • Interior/Exterior: Durable in dry and wet areas

    With our complete fast track flooring system, you can create the ultimate polished floor.

    Because TRU® contains just trace amounts of polymer, TRU® gives you high-gloss polished concrete with more clarity. Achieve high quality, high clarity, polished floors in fewer steps.

    Behind schedule? No problem. Our fast-track flooring system helps you bring jobs up to speed to meet deadlines.



    Concrete’s tonal differences, subtle cracks and aggregates can take on a stone-like, natural feel. Polished concrete changes a concrete floor surface, with or without aggregate exposure or color, to achieve a specified level of gloss. TRU® makes it easy to design and specify functional and beautiful polished concrete floors

    Let your TRU® creative ideas shine and sparkle in your floors. Use TRU® with aggregate to resemble the look of terrazzo, or use the color chart to create unlimited options of colored polished floors.

    In addition, create concrete gray floors that can be polished to expose the aggregate and simulate the appearance of polished concrete with TRU® Gray and TRU® PC Polished Concrete.


    ENVIRONMENTAL ADVANTAGES : TRU® is formulated with Rapid Set® cement. Rapid Set® has a much smaller carbon footprint than portland cement. This means that in its manufacturing process, with normal cement plant production equipment, it generates far less carbon dioxide (CO2) than portland cement emits during its production process.

    TRU® is engineered with the technically advanced Rapid Set® Cement. With Rapid Set Cement, you deliver fast, strong and durable results that are better for our environment.
