            asphalt surfaces and asphalt overlays. Concrete must exhibit
            3000 psi minimum strength. Concrete surfaces to be coated
            must be trowel finished in compliance with the American
            Concrete Institute (except that hand troweling is not required),
            followed by a fine hair brooming, left free of loose particles,
            and shall be without ridges, projections, voids and concrete
            droppings that would be mechanically detrimental to coating
            application or function. New concrete must be cured for 28
            days.

            Concrete cleaning (see general guidelines). Polycoat Products
            coating systems should not be subjected to rising water
            tables or hydrostatic pressure on slab-on-grade decks. The
            only acceptable grade of plywood is APA rated exterior grade
            or better. The appearance and physical characteristics of the
            plywood and grade should be considered. Plywood should be
            new or cleaned and sanded (see general guidelines). Coating
            should be applied at least 5°F (3°C) above the dew point.

            Coverage rates recommended are based on lab conditions,
            applied at 75°F (24°C) ambient temperature and are intended
            to be minimum coverage rates on clean, smooth plywood, and
            are exclusive of additional amounts needed to fill potholes,
            spallings, scalling, rough and irregular surfaces. Porosity
            and roughness of the substrate, aggregate size, and product
            temperature will affect coverage rates. Material mil thickness
            rates are calculated on theoretical coverage for a smooth
            substrate and do not account for the actual texture or substrate
            conditions in the field or at the time of application.  Sample
            mockups on the projects are recommended to determine
            the exact coverage rates necessary to waterproof the deck
            to acceptable standards. Equipment should be cleaned with
            a urethane grade environmentally safe solvent, as permitted
            under local regulations, immediately after use. Uncured
            materials are sensitive to heat and moisture. The substrate
            must be structurally sound and sloped for proper drainage.
            Polycoat Products assumes no liability for substrate defects.
            Field visits by Polycoat Products personnel are for the purpose
            of making technical recommendations only and are not to
            supervise or provide quality control on the job site
