Georgia-Pacific’s DensDefy Liquid Barrier, a fluid-applied air- and water-resistive barrier, produces a seamless, vapor-permeable membrane on exterior gypsum sheathing, wood sheathing, CMU, or concrete walls. Applied via roller or spray, the single-component, elastomeric product bonds to most materials without priming. The manufacturer says it can be installed in temperatures as low as 25°F, in wet weather, and on damp substrates, and that it cures in temperatures as low as 32°F and tolerates rain immediately after application.
