Product Description

Sherwin Williams Dura-Plate UHS is a rapid return to service, high build, edge retentive tank lining for prepared steel or concrete surfaces, industrial and marine exposures.

Best Uses

Sherwin Williams Dura-Plate UHS is best suited for use over prepared steel or concrete surfaces in industrial and marine exposures such as ballast tank interiors, oil storage tank interiors, refined fuel storage tanks, potable water tanks interiors and pipe (Certified to NSF/ANSI 61), water and waste treatment plants, primary and secondary containment areas where edge protection film build properties are required. Meets MIL-PRF-23236, Type VII, Class 5, 7, 9 and 11, Grade C.

Suitable for use with cathodic protection systems.


For steel prepare to BS EN ISO 8501-1 2007 Sa2½. Temperature (air, surface): 10°C minimum, 43°C maximum. 3°C above dew point. Material should be 21°C to 29°C for optimum application characteristics. Relative humidity: 85% maximum. Note: Recommended application procedure direct to steel: Apply a 125-150 micron coat to the substrate. Allow material to “wet” the surface. Then apply additional material, to bring total film thickness to the recommended range.

Minimum recommended surface preparation: Surface must be clean, dry and in sound condition. Remove all oil, dust, grease, dirt, loose rust and other foreign material to ensure adequate adhesion. Apply using airless spray, or brush and roller for stripe coats and touch up.
