Product Description:
Fast drying Commercial Topping^Â® pours from a featheredge to 3" (76 mm) in new construction or renovation projects. With compressive strengths of 4,000 psi (27.4 MPa) to 4,500 psi (31 MPa), it's the ideal underlayment to meet ASTM F 710, Preparing Concrete to Receive Resilient Flooring. It pours over VAT, VCT, terazzo or ceramic, with no shotblasting required. For the ultimate strong, smooth finish over concrete, precast, steel deck, wood frame, and old cracked lightweight concrete, specify Commercial Topping.

Now always a "green" building material, Commercial Topping is an ideal solution for sustainable building projects.
