Rapid Set TRU PC Polished Concrete: High Performance Architectural Topping. Choose Rapid Set TRU PC when you need a high-flow topping that simulates polished concrete. TRU PC is an advanced hydraulic cement-based, self-leveling topping that can be used both indoors and outdoors. This crack-resistant, durable, one-component system will not deteriorate in damp conditions. It is ideal for projects that require long flow life and working time while achieving high early strength.
TRU PC rapidly levels, maintains workability for up to 20 minutes, and produces a dense surface with high bond strength. Save time since TRU PC is ready for foot traffic in 2 to 3 hours; for coatings in about 12 hours; and grinding in 24 hours. TRU PC cures to a gray color with the non-uniform appearance of concrete. TRU PC also grinds and polishes well, making it an excellent choice for polished concrete floors. For flat surfaces, one 60-pound bag covers 16-18 square feet at 3/8-inch thick.
