Product Instructions:
For complete information associated with the application of all Polycoat Products systems and products, refer to the General Guidelines and Technical Bulletin sections of the Polycoat Products catalog, which describes the products, surface preparation, job conditions, finishing details and other necessary information.
Application:
Phase 1: Check area of application to ensure it conforms to substrate requirements. Prime all joints, cracks, and flashings with Polyprime 21 or U22 (mixture of Part-A & Part-B). Apply a two-part paste consisting of PC-440SF and PC-50 over all joints, cracks and flashing. Mixing ratio is pint of PC-50 to 1 gallon of PC-440SF (0.24 liters per 3.78 liters) or 1 quart PC-50 to 5 gallons of PC-440SF (0.9 liters per 18.9 liters). Do not mix more material than can be used in 20 minutes. Bridge the joints, cracks, and flashings with 4" (10 cm) Straight Jacket Tape pushing it into the paste with a trowel. Over Polyester Tape apply a stripe coat of the PC-440SF and PC-50 mixture and taper it onto the adjacent surface. Allow the surface to cure for up to 6 to 8 hours.
Phase 2: Prime the surface with Polyprime 21 or U22 at a rate of 1 gallon (mixture of Part-A & Part-B)/300 sq.ft. (0.14 liters/m2). Apply using a brush or phenolic core roller. This will result in 3 dry mils (76 microns) of coating. Allow Polyprime to become tack free before proceeding to Phase 3.
Primer is optional over new plywood.
POLYCOAT-AQUATIGHT?
System Data Sheet
POLYCOAT - AQUATIGHT?
System Description:
The Polycoat-Aquatight waterproofing system is a solvent-free, liquid applied, high solids, aromatic polyurethane, waterproofing membrane. The system utilizes an epoxy-polyamine primer, two coats of a solvent free aromatic polyurethane polyurea coating and a heavy grit sand aggregate. The Polycoat-Aquatight waterproofing system is a specialized application of a polyurethane coating as a waterproof underlayment for ceramic tile. The system is durable and will protect surfaces against spalling and freeze/thaw damage. It is an elastomeric system designed to expand and contract with normal structural movements. The system will not soften in heat nor embrittle in cold. The Polycoat-Aquatight waterproofing system has a wide range of application uses and, installed properly will ensure years of service.

Phase 3: Apply a mixture of PC-440SF and PC-50 (1 quart PC-50 to 5 gallons PC-440SF) to the substrate at a rate of 3 gallons/100 sq. ft.
(1.23 liters/m2). Do not mix more material than can be used in 20 minutes. For best results, apply using a notched trowel or squeegee. A
phenolic core roller may be used but extra care should be taken to prevent air bubbles. Spread PC-440SF and PC-50 mixture evenly over the
entire surface resulting in a 48 2 dry mils (1066 51 microns) membrane. Allow PC-440SF and PC-50 mixture to cure before proceeding to
Phase 4.
Phase 4: Apply a second coat of PC-440SF at a rate of 1 1/2 gallons/100 sq. ft. (0.62 liters/m2), spread evenly over the entire surface,
resulting in a 24 2 dry mils (610 51 microns) membrane.
Phase 5: When adhering tile directly to the Polycoat-Aquatight waterproofing system, broadcast washed, dry, angular sand, heavy, 16 grit
(0.0469" or 1.18 mm) or larger aggregate into the final coat of PC-440SF. Allow the membrane to cure, remove the excess aggregate, and
apply a thin set mortar when ready for tile installation.
When utilizing a mortar bed over the Polycoat-Aquatight waterproofing system, allow the completed membrane to cure prior to installation of
the float. A water test can be conducted after 24 hours.
Finished System:
When applied as directed, the Polycoat-Aquatight waterproofing system will provide 72 dry mils (1829 microns), exclusive of fabric, of
superior waterproofing protection. Requires a continuous coating application to minimize lines and/or streaking. Any optional adhesion test is
to be performed seven days after product application.

Limitations:
The following conditions must not be coated with Polycoat Products coating systems or products: Concrete over an unvented metal pan,
magnesite, lightweight concrete, 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 and masonry must be cured for 28 days. Concrete cleaning (see
General Guidelines). 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.
Warning:
The products in this system contain Isocyanates, Aromatic Hydrocarbons, Curatives and Solvents.
