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
