Three More Prosoco Coatings are Qualified for LEED V4

Leed v4Three Prosoco products – Interior Masonry Dustproofer, Siloxane WB Concentrate, and BMC II, now contribute to LEED v4 low-emitting materials credits after independent testing by Berkeley Analytical.

This development is Prosoco’s response to demand within the LEED commercial and interior design community, according to Dwayne Fuhlhage, Sustainability Director for Prosoco.

Designers have been asking for LEED v4-ready products that protect and maintain CMU and precast concrete. They also want it for refinishing interior, exposed brick and concrete — a popular trend in retrofits, he said.

“Design professionals are looking for products that help them achieve the IEQ Low Emitting Materials credit,” Fuhlhage said. “Siloxane WB Concentrate solves a problem by protecting interior parking decks from water and salt. Existing building retrofits created demand for a product like Interior Masonry Dustproofer to stabilize chalky, exposed brick interiors.”


Likewise, BMC II has been a specified solution for decades on projects needing tough protection from a coating, such as the U.S. Capitol and countless other buildings with exposed CMU, masonry and concrete.

The qualification of BMC II products for LEED v4 low-emitting materials credits is another example of Prosoco’s ability to both purposefully and nimbly direct research and product development resources to timely demands in the industry, Fuhlhage said.

“Testing VOC emissions for interior applications demonstrated a need to do an informed substitution for one of our co-solvents,” he said. “Our R&D team came up with a solution that doesn’t impact performance.”

Through independent testing with Berkeley Analytical, these products conform with the California Department of Public Health (CDPH) Standard Method V1.2. They also qualify for project teams using WELL, Collaborative for High Performance Schools (CHPS), and green building codes such as CALGreen, ASHRAE Standard 189.1, and the International Green Construction Code (IgCC).

Since 2008, Prosoco has partnered with Scientific Certification Systems (SCS) for verified third-party certification. With these additional products becoming certified, Prosoco now offers 21 LEED v4-ready products with the SCS Indoor Advantage Gold certification.

More about the products:
  • Interior Masonry Dustproofer – Waterborne treatment that protects and prevents further dusting of brick, mortar, natural stone and other porous masonry.
  • Siloxane WB Concentrate – Water-based, high-performance water repellent that protects surfaces from staining and deterioration.
  • BMC II (all tint bases) – Breathable coating for interior or exterior masonry surfaces. This protects them from water intrusion while also allowing vapor to escape.

Prosoco will be showcasing these products and others that provide design professionals with solutions for their LEED v4 projects at Greenbuild, Nov. 19-22, 2019. To learn more, find them  in the mindful Materials Pavilion on the Greenbuild expo floor. You can also visit the mindful Materials database or visit us at
