POLYDECK 150/150SC
®

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). 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,
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.
