Water-repellent Sealer is Newest Product in the Company's Comprehensive DRY-BLOCK Wall Protection System

CAMBRIDGE, Massachusetts -- Grace Construction Products, a world leader in the construction products industry, has introduced INFINISEAL™ DB water repellent sealer. INFINISEAL DB is a unique, specially formulated sealer designed to provide maximum water repellence when applied to new and existing DRY-BLOCK® concrete masonry structures.

This clear and penetrating sealer is the newest product in the company's comprehensive DRY-BLOCK Wall Protection System -- a three-product system approach that provides unsurpassed water repellence. The system consists of DRY-BLOCK Block Admixture, DRY-BLOCK Mortar Admixture and INFINISEAL DB.

"We are very excited about the introduction of INFINISEAL DB," noted Jeremy Gray, general manager of Grace Construction Products' Masonry Unit. "This product complements our existing line of water-protection products and provides our customers with unsurpassed water repellence when used as part of our comprehensive wall protection system. INFINISEAL DB is just one more example of Grace's commitment to innovation and technology."

INFINISEAL DB is a water-based blend of silanes and siloxanes and is VOC (Volatile Organic Compound) compliant. It is recommended for use on structures constructed with DRY-BLOCK concrete masonry units and DRY-BLOCK mortar. INFINISEAL DB helps minimize the risk of efflorescence and lessens the likelihood of mold, mildew and algae in or on the wall by further reducing the amount of water that can penetrate the wall system.

Ready-to-use, this product can be applied with a sprayer, a roller or brush to the outside surface of the structural walls. Cleanup is easy. Simply remove equipment and surface residue with warm, soapy water. INFINISEAL DB will surface dry within one to three hours or longer depending on air and surface temperatures and humidity. Full sealer cure can take up to 28 days and water repellency properties should be visible within one day following application.

INFINISEAL DB is available in five gallon pails and 55 gallon drums. For more information, customers can contact their local Grace Construction Products salesperson or visit the website at
