3. Product DescriptionSchönox, HPS North America, Inc., the exclusive provider of Schönox products to the North American marketplace, offers a full line of primers, moisture mitigation systems, repair products, leveling compounds and adhesives to solve residential and commercial flooring challenges.

Basic UseSchönox self-leveling underlayments, underlayment systems and compounds prepare interior substrates for subsequent floor covering — creating hard, smooth surfaces, while helping avoid demolition of existing substrates. Schönox offers underlayment products suited for a range of applications, including rough, cracked and unlevel wood, concrete and cement in new construction and renovation projects.

Schönox APSchönox AP is a synthetic gypsum-based self-leveling compound for the smoothing and leveling of substrates under flexible coverings and wood floors with layer thicknesses of at least 1⁄8 inch. Designed for interior areas, Schönox AP is suited for:●● Gypsum, concrete and cement based substrates●● Ceramic tile, terrazzo and sheet vinyl●● Old water-resistant adhesive residues●● OSB board and plywood

Schönox AP can be installed in layer thicknesses of 1⁄16 inch to 11⁄4 inch without aggregates and 2 inch with aggregates.

Schönox APF Schönox APF is a fiber-reinforced, synthetic gypsum-based self-leveling compound for wooden floors and critical interior substrates. With embedded fibers that make reinforcement fabric unnecessary.
