Polycoat Staingard™ 7072SC is an aliphatic, polyaspartic, environmentally-friendly surface topcoat for waterproofing membrane systems.

 Polycoat Staingard 7072SC is an aliphatic, polyaspartic, polyurea topcoat designed as a quick-curing, UV-resistant surface coat for waterproofing membrane systems. It serves as a high-gloss, abrasion-resistant, seamless coating suitable for environments requiring chemical resistance and long-term durability.

 This material is used as a topcoat in a multi-layer waterproofing membrane system. When recoating or applying over a previously primed surface where more than 12 hours have elapsed, a re-prime with Polyprime U is required before applying the pigmented version of Staingard 7072SC. If a clear coat is required, it must always follow the pigmented coat to prevent discoloration of the primer layer.

·       Concrete surfaces

·       Cold storage areas

·       Chemical and fertilizer plants

·       Food processing facilities

·       Industrial warehouses

·       Offshore oil platforms

·       Pipeline barges

·       Steel and plastic substrates

·       Pulp and paper mills

·       Mix Ratio: 1A:1B by volume

·       Application Methods: Phenolic resin core roller, high-pressure spray, or cup gun under low pressure

·       Minimum Film Thickness: 5 mils

·       Typical Dry Film Thickness per Coat: 14 ± 2 mils

·       Coverage Rate: Approx. 1 gallon per 100 sq ft

·       Pot Life at 75°F (24°C), 50% RH: 25–30 minutes (Clear), 45–60 minutes (Pigmented)

·       Curing Time:

o   Initial cure: 2–4 hours

o   Light foot traffic: after 6 hours

o   Full cure/heavy foot traffic: 24–48 hours

·       Mixing Instructions: Do not dilute; mix components separately and then combine Side-B into Side-A. Mix mechanically for at least 5 minutes, avoiding air entrapment.

·       UV Resistance: Excellent UV resistance and color stability; clear topcoat provides superior gloss retention.

·       Environmental Conditions:

o   Ideal application temperature: 60–95°F (15–35°C)

o   Sensitive to heat and humidity—these accelerate curing and may reduce working time.

o   Low temperature and humidity will extend curing time.

·       Limitations:

o   Not suitable for split slabs, buried membranes, sandwich slabs with insulation, or unvented metal pans.

o   On-grade slabs must be tested for moisture-vapor transmission.

o   Clear coat may turn opaque if exposed to moisture.

o   Open containers must be used promptly.

o   Not for use over asphalt without technical consultation.
