Waterproof flooring material is self-curing.</p> <p>FIELD QUALITY CONTROL <br />A.</p> <p>Thickness: <br />Total approximate thickness of waterproof flooring material shall be 60 mils (1.5 mm) dry film.</p> <p>B.</p> <p>Do not overcoat waterproof flooring material with solvent-based materials.</p> <p>096700-4 Fluid-Applied Flooring in Mechanical Rooms</p> <p>3.6</p> <p>C.</p> <p>Prime and protect alkali sensitive metals such as copper, aluminum, galvanized or zinc treated metal <br />first with a primer, before over-coating with waterproof flooring material. Follow manufacturer’s <br />recommendations for primer material.</p> <p>D.</p> <p>Where a uniform color is desired, application of an elastomeric paint or water based acrylic stain is <br />recommended.</p> <p>ACCEPTANCE <br />A.</p> <p>Remove left over materials and any foreign material resulting from the work from the site.</p> <p>B.</p> <p>Clean adjacent surfaces and materials. <br />END OF SECTION</p> <p>Project: ........
