Rapid Set® Tru Self Leveling, High Performance Architectural Topping, Natural, 50 lbs

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 shot blasting, 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.

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 1/2" below desired floor level and then place neat TRU™ for the final 1/2" 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.
