Product Description
Barritech NP is a fluid-applied membrane made of fire-retardent, synthetic polymer composition. Barritech NP is applied to exterior wall assemblies where it functions as an air barrier, vapor barrier and a water-resistive barrier. Barritech NP can be applied over concrete block, concrete, exterior gypsum sheathing, plywood, OSB and many other common building materials. The product is fully adhered to the substrate, flexible and rubber-like. Barritech NP is a single-component, air-drying product applied by spray or roller at nominal 0.040" (40 mils) dry film thickness. The high film thickness and flexible, elastic properties enable Barritech NP to bridge cracks and seal around penetrations, which creates a truly continuous, monolithic air, vapor and water barrier.
This is a stock item available in 50 gallon drums and 5 gallon pails.
