DensDefy Liquid Barrier is a fluid-applied, air- and water-resistive barrier that creates a seamless, durable membrane on exterior gypsum sheathing, wood sheathing, CMU and concrete walls. It’s a single-component, monolithic, elastomeric, STP-based barrier that helps protect against water intrusion and mitigates the risk of unwanted air movement.
Cures quickly, including in wet conditions, and is vapor-permeable, so it allows damp surfaces to dry. Can be applied in temperatures as low as 25 degrees F. and cures in temperatures as low as 32 degrees F.
