Confirm and record above values at least once every 3 hours during installation or more frequently whenever conditions change (e.g. Ambient Temperature rise/fall, Relative Humidity increase/decrease, etc.). Concrete substrate to have a minimum compressive strength of 25 MPa (3,625 psi) at 28 days and a minimum of 1.5 MPa (218 psi) in tension at time of application. Ensure concrete substrate conforms to the minimum requirements of the flooring manufacturer. Do not flooring system to sand-cement setting beds. Remove sand-cement beds to structural concrete substrate. Re-level/slope as required to achieve grade and/or drainage in accordance with manufacturer’s minimum requirements. Do not flooring system to asphaltic or bitumen membranes, soft wood, aluminum, copper or fiberglass reinforced polyester/vinyl ester composites. Apply to glazed or vitrified brick and tile, structural wood, and steel only with manufacturer’s written recommendation for proper surface preparation. SURFACE PREPARATION Prepare surface to receive flooring systems in accordance with manufacturer's written instructions. Remove dirt, oil, grease, wax, laitance, curing compounds, water-soluble concrete hardeners, and other surface contaminants. Remove sealers, finishes, and paints. All projections, rough spots, etc. should be removed and patched to achieve a level surface prior to the application. Remove unsound concrete by appropriate mechanical means. Concrete: Clean and prepare to achieve laitance-free and contaminant-free, open textured surface by shot blasting or equivalent mechanical means. Provide CSP level in accordance with ICRI Guideline No. 310-2R and manufacturer’s written recommendation. Chemical Surface Preparation: Chemical surface preparation (acid etching) is unacceptable and will void manufacturer’s warranty. Control Joints and Cracks: Repair and treat control joints and surface cracks utilizing manufacturer’s standard materials and installation details.
