            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 (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). Coatings 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,
            spalling, scaling, 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.


            Warning
            The products in this system contain Isocyanates, Solvents, and Curatives.
