TRU® Self-Leveling

Rapid Set® TRU® Self-Leveling:  Floor Topping, Resurfacing & Underlayment

Choose Rapid Set® TRU® Self Leveling when a high-quality and fast floor topping, resurfacer or underlayment is required. TRU Self Leveling is an advanced hydraulic cement-based, self-leveling topping, resurfacer and underlayment that can be used both indoors and outdoors. This crack-resistant, durable, one-component system won’t deteriorate in damp conditions.  It is ideal for projects that require long flow life and working time while achieving high early strength.

TRU rapidly levels, maintains workability for 30 minutes, and produces a smooth, strong surface with high bond strength. Save time since TRU Self Leveling is ready for foot traffic in 2 to 3 hours and for coatings in about 12 hours. 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 an excellent choice for polished decorative floors.   For flat surfaces, one 50-pound bag covers 22-24 square feet at ¼-inch thick and 11-12 square feet at ½-inch thick.

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.

The TRU PC and TRU Self-Leveling Spiked Rollers are designed for self-leveling overlays.  They release trapped air produced during mixing, significantly reduces pinholes, results in a flatter floor, and are easy to clean.  Learn more about these specialty finishing rollers.

Standard Practices

Q: What is Rapid Set® TRU® and what can it be used for?
A: Rapid Set® TRU® is a Self-Leveling Topping, Resurfacer, and Underlayment that can be used indoors and outdoors.  TRU can be used as a topping over concrete to provide a new, fresh appearance. It can be used to fill low spots, correct unevenness or sloped floors and as an underlayment under tile, carpet, or epoxy.

Q: Can TRU be polished?
A: Rapid Set TRU is ideal for polished, decorative floors due to its high early strength and low polymer load. These advantages allow TRU to be polished to a high luster with excellent clarity in as little as 24 hours after placement.

Q: Can color be added to TRU?
A: Yes. Integral colors may be used as required. Liquid pigments are recommended because they generally have a lesser effect on the flow of TRU. However, the type of color and the amount used may alter and/or decrease the performance characteristics of TRU. Stains and dyes can also be an effective means of coloring the TRU. With any method, a test pour should be conducted using uncolored TRU as well as TRU with the intended color for comparison. If the color negatively impacts the characteristics of TRU, the color additive should be reduced or eliminated.

Q: Does TRU require a primer prior to placement?
A: Yes. When TRU is placed over a porous substrate trapped air in the substrate migrates to the surface causing pin holes and bubbles.  A primer seals the surface of the substrate, reducing or preventing pin holes. Primers can also reduce water loss into the substrate and increase adhesion..

Q: What type of primer should I use with TRU?
A: CTS Cement recommends the use of Rapid Set® TRU Epoxy Primer (TXP) for best results in decorative or polished floor applications. For all other applications, Rapid Set Acrylic Primer is acceptable.

Q: How should I mix TRU and can it be pumped?
A: Batch mixers by CS Unitec (Hippo Mixer) or Strong Manufacturing are the preferred methods of mixing TRU to achieve uniform mixing throughout the batch. TRU can also be mixed in buckets or barrels with a 650 rpm drill and “helix style” paddle mixer. A batch mixer and mortar pump can be used for placement.

Q: Is TRU as fast as other Rapid Set® products?
A: TRU provides much more working time than typical Rapid Set® products.  At 70° F, TRU has a 15 minute flow life and can provide up to 30 minutes working time.
