Commercial Topping® 
Ultimate Strength Floor Underlayment
New, fast drying Commercial ToppingĀ® pours from a featheredge to 3" (76 mm), in new construction or renovation projects. With compressive strengths from 4000 psi (28 MPa) to 4500 psi (31 MPa), it's the ideal underlayment to meet ASTM F 710, Preparing Concrete to Receive Resilient Flooring.
Commercial Topping pours over VAT, VCT, terazzo or ceramic, with no shotblasting required. For the ultimate strong, smooth finish over concrete, precast, wood frame, and old cracked lightweight concrete, specify Commercial Topping.
Commercial Topping is now always a building material!
