USG Offers New Family of Poured Underlayments with High Compressive Strengths and Self-Leveling Properties
USG's Tile and Flooring Division has introduced an innovative new family of poured, self-leveling cement underlayments called ULTRAFLOW(TM) Brand Floor Underlayment.
All four of the new products offer high compressive strengths, performance and versatility, utilizing a uniquely engineered cement chemistry. The self-leveling underlayments come pre-sanded in a bag, mix easily at the job site and can be applied in a wide range of commercial, institutional and residential flooring applications. They are available nationally through tile and flooring distributors.
ULTRAFLOW G-1.0 Floor Underlayment is a high-quality, non-shrinking floor underlayment designed for use in residential, light-commercial and renovation construction. Fast setting and self-leveling, the underlayment requires no shotblasting. It can be applied easily over wood and concrete subfloors from 3/8 to 2 inches thick, and features a compressive strength of 3,500 to 4,200 psi at 10 to 14 days.
ULTRAFLOW 2.0 Floor Underlayment is an economical Portland-based, self-leveling, cementitious underlayment designed for fast application and setting. Ideal for application over concrete, as well as wood substrates with metal lathing, it provides a crack-resistant surface that can handle light construction traffic 24 hours after being poured. The product is mixed with water at the job site to produce a smooth, monolithic surface. Permanent floor coverings can be applied three to seven days after the material is poured, depending on the underlayment's thickness and the drying conditions. The product can be applied from feather edge to 2-inch thicknesses, and offers a compressive strength of 5,500 psi at 28 days.
Self-drying and moisture resistant. ULTRAFLOW 3.0 Floor Underlayment will accept floor coverings after 24 hours. This polymer-modified engineered cement is ideal for leveling or topping rough and spalled (but structurally sound) concrete when downtime is critical. The product applies and sets quickly, permitting light traffic within a three-hour period. It can be poured from feather edge to 1 ¼-inch thicknesses, and is designed for commercial, institutional and rehab construction. The underlayment can be covered in 24 hours with carpeting, ceramic surfaces, homogenous PVC and wood underlayment over concrete slabs, and provides a compressive strength of 4,350 psi at 28 days.
ULTRAFLOW 4.0 Floor Underlayment is a premium, self-drying cementitious wear surface designed to act as either a final floor surface or high-performance underlayment. The polymer-modified, engineered cement underlayment's fast application and setting times permit the return of light trade traffic within 24 hours. It is recommended for high-traffic areas, including manufacturing facilities and warehouses where forklifts are active. The material requires no floor covering or coating, but a sealer or coating can be applied if additional performance is needed. The underlayment can be applied from feather edge to 5/8-inch thicknesses, providing a moisture-resistant surface. It offers a compressive strength of 4,350 psi at 28 days.
