Polycoat Staingard™ 9072SC is an aliphatic polyaspartic, environmentally friendly, highly chemical resistant surface topcoat for waterproofing membrane systems.

Polycoat Staingard 9072SC – Aliphatic, Polyaspartic, Polyurea Waterproofing Membrane Topcoat.

 Polycoat Staingard 9072SC is designed as a high-performance, chemical-resistant, UV-resistant, aliphatic polyaspartic polyurea topcoat. It is primarily used as the final surface layer over waterproofing membrane systems and offers superior weatherability, abrasion resistance, and gloss retention.

 This product functions as a topcoat in waterproofing systems and is compatible with aromatic polyurea, polyurethane, and epoxy base membranes. When re-coating beyond 12 hours of prior clear coat application, a primer such as Polyprime U is required before applying a pigmented topcoat. Clear coats must be applied only after the pigmented coat, never directly over primer to avoid discoloration.

 Ideal for use in highly demanding industrial and commercial environments, including:

·       Concrete surfaces

·       Off-shore oil platforms

·       Chemical and fertilizer plants

·       Cold storage and food processing areas

·       Warehouses, steel and plastic substrates

·       Pipeline barges, plywood, and pulp/paper mills

·       Mixing Ratio: 1:1 by volume (Side-A : Side-B)

·       Application Tools: Airless sprayer (preferred), phenolic resin core roller, or cup gun under low pressure

·       Minimum Film Thickness: 5 mils

·       Recommended Film Thickness: 14 ± 2 mils (dry film) per coat

·       Coverage Rate: 1 gallon covers approximately 100 ft²

·       Pot Life: 45–60 minutes at 75°F (24°C), 50% R.H.

·       Curing Time:

o   Tack-free: 2–4 hours

o   Light pedestrian traffic: after 6 hours

o   Heavy pedestrian traffic: 24–48 hours

·       Environmental Conditions: Apply between 60–95°F (15–35°C); avoid high humidity and excessive heat, which can accelerate curing undesirably. Do not apply on surfaces with moisture or in high-moisture environments.

·       UV Stability: UV-resistant with excellent gloss retention – suitable for exterior use.

·       Chemical Resistance: Resistant to a wide range of chemicals including acids, solvents, oils, fuels, and Skydrol (per ASTM D1308 test data).

·       Surface Preparation:

o   Metal: SSPC-SP6/NACE 3 with 2 mil (50 micron) profile.

o   Concrete: SSPC-SP13/NACE 6 or ICRI CSP 3-5 – Primer required.

·       Storage: Shelf life of 1 year in factory-sealed containers stored indoors.

·       Limitations: Not suitable for split slabs, buried membranes, magnesite, sandwich slabs with insulation, or non-structural lightweight concrete. Avoid use on unvented metal pans or asphalt surfaces unless approved by Polycoat technical department.
