FREQUENTLY ASKED QUESTIONS
Rapid Set TRU SP is a self-leveling overlayment that can be polished to expose a salt and pepper appearance. TRU SP is ideal for polished concrete floors in schools, airports, warehouses, retail, restaurants, lobbies, and more.
TRU SP can be polished after 24 hours at normal conditions. It polishes much like concrete and can achieve high gloss and clarity.
Yes. TRU SP comes in a natural color ideal for adding integral colors. Liquid pigments are recommended because they generally have a lesser effect on the flow of TRU SP. However, the type of color and the amount used may alter and/or decrease the performance characteristics of TRU SP. Stains and dyes can also be an effective means of coloring the TRU SP. With any method, a test pour should be conducted using uncolored TRU SP as well as TRU SP with the intended color for comparison. If the color negatively impacts the performance, the color additive should be reduced or eliminated.
Mix TRU SP with 4.0 - 4.5 quarts of potable water per bag. Use the least amount of water possible to keep the aggregate near the surface. Grind until the aggregate exposure is as required.
TRU SP can be placed at a minimum thickness of 3/8" (10 mm) onto a prepared and primed substrate. Finished floors subject to high load traffic must be applied at a minimum of 1/2" (13 mm) thick.
Yes. When TRU SP 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.
Multi-bag batches produce more uniform results. Use an ICRI 320.5R #P2 or #P9 helix-style paddle with a Hippo Mixer or similar batch mixer to achieve a uniform mix consistency. After the final bag is added to the batch, mix an additional 2-3 minutes until the mixture is lump-free. After proper mixing in a batch mixer, a mortar pump can be used to pump and place material if required.
TRU SP is designed to provide more working time than some Rapid Set products. At 70 degrees, TRU SP has a 15 minute flow life and can provide up to 20 minutes working time.
TRU SP can be ground and polished to expose a salt and pepper aggregate finished appearance. TRU PC has a coarse sand and can be ground and polished to simulate the appearance of polished concrete.
