Coating Made for Concrete Refill

THURSDAY, DECEMBER 3, 2015


The Sherwin-Williams Company Protective & Marine Coatings division has introduced an epoxy-modified cementitious resurfacer that the company says patches and refills voids and bug holes in concrete and masonry substrates.

Dura-Plate 2300 provides a hard, durable surface with good adhesion, according to the company. The new product also minimizes pin-holing and outgassing problems sometimes associated with coating concrete.

The coating is suitable for resurfacing concrete prior to coating and lining applications for a range of environments, according to the company. Industrial applications include water and wastewater; oil and gas; pharmaceutical; bridge and highway; food and beverage; power generation; mining; sewer collection; atmospheric and immersion service; and secondary containment.

Coating Details

The company says the coating is abrasion-resistant and is part of a three-component kit that contains Portland cement, hydrophobic thixotropes, fiber reinforcement, graded silica sand and other aggregates. The kit consists of Part A Epoxy, Part B Hardener and Part C Mortar in a single package.

Sherwin-Williams says the product can be applied in a range of temperatures. When used at 75 degrees Fahrenheit, the Dura-Plate 2300 can be dry to the touch within 3 to 4 hours. It can be applied at a minimum of 40 degrees Fahrenheit, according to the company.

The coating also has an unlimited recoat window because it can be reagitated to reduce viscosity and improve workability time inside a 70-minute potlife, the company says.

The manufacturer says the Dura-Plate 2300 is available in a flat concrete gray; can be applied by a hand-trowel or spray; has a film build-up of up to ½ inch per lift; and can be top-coated within 8 to 24 hours depending on the top-coating type.
