DensDefy® Liquid Barrier
- Provides a durable, seamless water-resistive, air-barrier membrane.
- Easily applied to a variety of different substrates via roller or spray.
- Pair the DensDefy® Liquid Barrier System with the DensElement® Barrier System ensures coverage by a single, comprehensive warranty from Georgia-Pacific.
- Can be applied in temperatures as low as 25°F, cures at 32°F, and is resilient enough for wet weather conditions, as it can be applied on damp substrates and tolerates rain immediately after application.
- Vapor permeable – allows damp surfaces to dry.
- Can be exposed to normal weathering conditions for up to 12 months.
Product Details
Engineered for performance and durability, the DensDefy® Liquid Barrier is the ultimate solution for water-resistive and air barrier systems. Designed for application with a roller or spray equipment, this advanced Silyl Terminated Polymer (STP) technology forms a robust, elastomeric membrane, providing unmatched adhesion to common construction surfaces such as CMU, concrete, glass mat gypsum sheathing, OSB, and plywood. Combined with DensDefy® accessory materials, this product ensures a seamless protective barrier for any build.
