FREQUENTLY ASKED QUESTIONS
Rapid Set TRU is a high-performance, polishable self-leveling Topping, Resurfacer, and Underlayment that can be used indoors and outdoors. TRU can be used as a topping over concrete to provide professional finished appearance. It can be used to fill low spots, correct unevenness or sloped floors and as an underlayment under tile, carpet, or epoxy.
Yes, Rapid Set TRU is ideal for polished, decorative floors due to its high early strength and hardness. These advantages allow TRU to be polished to a high luster with excellent clarity in as little as 24 hours after placement.
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 performance, the color additive should be reduced or eliminated.
Yes. When TRU is placed over a porous substrate trapped air in the substrate migrates to the surface causing pinholes 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.
For most applications, the Rapid Set GXP or TXP line of epoxy primers is recommended. Consult with your local CTS representative to determine which primer is right for your application.
Batch mixers are the preferred methods of mixing TRU. Multi-bag batches produce more uniform results. For small projects TRU can also be mixed in buckets or barrels with a 650 rpm drill and ICRI 320.5R Mixing Paddle #P2 or #P9 Helix style paddle mixer. A batch mixer and mortar pump can also be used for placement.
Yes. If you would like a TRU Self Leveling, TRU SP and TRU PC Color Chart, contact your local Rapid Set representative or call our office at 1-800-929-3030.
