Sherwin-Williams Protective & Marine Coatings announced the launch of Dura-Plate 2300, an epoxy-modified cementitious resurfacer for patching and filling voids and bugholes in concrete and masonry structures. Dura-Plate 2300 provides a hard, durable surface with excellent adhesion that minimizes the potential for pin-holing and outgassing problems typically associated with coating concrete.

The abrasion-resistant coating is part of a complete three-component kit from Sherwin-Williams that contains Portland cement, hydrophobic thixotropes, fiber reinforcement, graded silica sand and other aggregates. It contains the Part A Epoxy, Part B Hardener, and Part C Mortar in a single packaged solution that makes ordering simple, while saving time with processing and application on the job.

“Dura-Plate 2300 is the perfect alternative to the high cost of epoxy resin fillers and the curing restrictions associated with cementitious resurfacers,” said Kevin Morris, Water and Wastewater Market Director, Sherwin-Williams Protective & Marine Coatings.

With a wide range of application temperatures, the product allows for a longer season for application. Its unlimited recoat window accommodates any project demands, as it can be reagitated to reduce viscosity and improve workability time inside of its lengthy 70-minute pot life.

Dura-Plate 2300 can be dry to touch in three to four hours and cures for immersion in 12 hours at 75° F. The product can be applied at a minimum of 40° F. Without the need for heated cure in colder temperatures and moist curing in hot environments, Dura-Plate 2300 prevents the application and curing restrictions associated with cementitious repair mortars.

Available in flat concrete gray, Dura-Plate 2300 can be applied via hand trowel or spray at package consistency and it releases easily from the trowel to reduce worker fatigue. The addition of potable water can aid in spray application characteristics.
“With concrete being the most commonly used construction material in the world and knowing that concrete commonly experiences placement defects, Dura-Plate 2300 provides an easy and economical solution for resurfacing,” Morris said.

The Sherwin-Williams Dura-Plate 2300 resurfacer has an excellent film build up to ½” thickness per lift and it can be top-coated in eight hours with nonflake-filled coatings and 24 hours with flake-filled coatings.

Dura-Plate 2300 is suited for resurfacing concrete prior to coating and lining applications for a wide range of environments, including water and wastewater facilities, the oil and gas industry, pharmaceutical facilities, bridge and highway, food and beverage sites, power generation facilities, mining, sewer collection, atmospheric and immersion service, and secondary containment.
