Examine substrates, areas and conditions, with Applicator present, for compliance with requirements for <br />maximum moisture and soluble ion content, installation tolerances and other conditions affecting flooring <br />performance. Verify that substrates and conditions are satisfactory for flooring application and comply with <br />requirements specified. <br />B. Contractor must report, in writing, surfaces left in improper condition by other trades. Application will <br />constitute acceptance of surfaces by the Applicator. <br />C. Do not proceed with application until the surface is accepted by the Manufacturer and authorization to <br />proceed is given by the Architect. <br /> <br />3.2 PREPARATION <br /> <br />A. General <br />1. New and existing concrete surfaces shall be free of oil, grease, curing compounds, loose <br />particles, moss, algae growth, laitance, friable matter, dirt, and bituminous products. <br />Docusign Envelope ID: 186E0FF8-664C-4A5C-9F97-28196CE69FD1
