Additional Information

SUITABLE SUBSTRATES (indoor, properly prepared) Group 1 exterior-grade plywood and/or oriented strand board (OSB) that is 5/8in. (16 mm) minimum thickness and a minimum of 19in. (48 cm) on center. Installation requirements (finished flooring, load, use and/or deflection) may first require the application of diamond lath or diamond mesh (meeting ASTM C847) over the primed surface before applying NA 400. Differential or excessive movement within the substrate may lead to cracks. Cement backer units, concrete mortars and leveling coats, ceramic tile, vinyl composition tile (VCT), cement terrazzo and thin layers of old cutback adhesive residue that are well-bonded and dimensionally stable. Surfaces must be properly prepared, bonded, primed, and free from dirt and dust. Install several correctly located test areas to ensure compatibility, bond strength and performance of the complete flooring system. Contact Technical Services for installation recommendations regarding substrates or conditions not listed. *THICKNESS AND APPROXIMATE COVERAGE based on a 50lb. (22,7 kg) bag.

Care

LIMITATIONS: Do not install over substrates containing asbestos. Before installing NA 400, properly prepare the surface and prime with NA 310 primer. For details, see Technical Data Sheet (TDS) for NA 310. Use between 50?F and 95?F (10?C and 35?C). In cooler conditions, use indirect auxiliary heaters to maintain ambient and substrate temperatures within the required range. For temperatures above 85?F (29?C), follow ACI hot-weather application guidelines to ensure a successful installation. For indoor use in dry areas only. Do not use as a wear surface. Let NA 400 cure: At least 24 hours before installing ceramic tile or natural stone; 2 to 3 days before installing carpet, vinyl sheet goods, vinyl tile, VCT, homogenous PVC, rubber and engineered wood plank. Thicker applications may require additional cure time. Do not install NA 400 over particleboard, chipboard, Masonite, Luaun, metal, asbestos, gypsum-based patching materials or any other non-dimensionally stable materials.
