Liquid Barrier

Georgia-Pacific announces the launch of DensDefy™ Liquid Barrier, a fluid-applied, air- and water-resistive barrier. Once applied, DensDefy™ Liquid Barrier produces a seamless, durable membrane on exterior gypsum sheathing, wood sheathing, CMU and concrete walls.


A new product within the DensDefy™ Products line, DensDefy™ Liquid Barrier works side-by-side with the DensElement® Barrier System and ForceField® Weather Barrier to provide a high-performance, highly durable WRB-AB system across multiple substrates, including DensGlass® Gold Sheathing.


The perfect companion for the DensElement® Barrier System, the new DensDefy™ Liquid Barrier is a single-component, monolithic, elastomeric, STP-based water-resistive barrier and air barrier. Developed to help protect against water intrusion and mitigate the risk of unwanted air movement, the product cures quickly (and in wet conditions), is exceptionally durable, and is vapor permeable, meaning it allows damp surfaces to dry.


DensDefy™ Liquid Barrier can be applied in temps as low as 25°F and cures in temps as low as 32°F. It also can be exposed to normal weather conditions for up to 12 months.


Use of DensDefy™ Liquid Barrier is easy to apply via roller or spray. Additionally, this product allows for continuity of the WRB-AB regardless of change in substrates; can be applied to produce a seamless, durable membrane on exterior gypsum or wood sheathing; and bonds to most common materials without priming. DensDefy™ Liquid Barrier is also compatible with many sealants and waterproofing accessories.
