            Limitations
            The following conditions must not be coated with Polycoat
            Products deck coating systems or products: on grade slabs,
            split slabs with buried membrane, sandwich slabs with
            insulation, slabs over unvented metal pan, magnesite, or
            concrete with a structural integrity less than 3000 psi. Asphalt
            surfaces and asphalt overlays may be coated with Polycoat
            decking systems if first coated with the Polycoat™ PC-IM 129.
            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-haired 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.

            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.
