322 K-NRG Seal VI is a liquid-applied- elastomeric membrane designed to provide a vapor impermeable air & water barrier when applied to above-grade wall assemblies. This product is a single-component, water-based acrylic coating that cures to a tough, monolithic rubber-like membrane with expansion and contraction properties that also resists air leakage. 322 K-NRG Seal VI incorporates antimicrobial technology to product a mold-resistant membrane.

322 K-NRG Seal VI is a liquid applied membrane used to construct high performance building envelope air & water barrier membrane assemblies requiring vapor impermeability. When combined with KARNAK’s sealants and accessories, 322 K-NRG Seal VI forms a complete vapor-impermeable wall air-barrier system. Used on sheathing and a variety of wall substrates prior to installation of exterior cladding.
Surface Preparation
Surfaces should be clean and free of frost, oil, grease, dirt, excess mortar or other contaminants. Recommended application temperature is 40°F to 120°F. All surfaces must be sound and dry. New concrete should be cured a minimum of 7 days before 322 K-NRG Seal VI is applied. Concrete surfaces should be sound and free of large voids and spalled areas. CMU wall mortar joints should be flush with wall without excess mortar. Joints between panels of exterior grade gypsum, plywood and rigid insulation up to 1/4” wide should be filled with a trowel application of 323 K-NRG Gap Seal™ prior to application of liquid membrane. Joints between 1/4” – 1/2” wide should be three-coursed with 323 K-NRG Gap Seal and reinforcement fabric. Reinforcing fabric should extend 3” beyond each side of the joint and be completely covered with another layer of 323 K-NRG Gap Seal. Joints wider than 1/2” are not permitted. Steps should be taken to use an appropriate backer material to fill the joint first before three-coursing with 323 K-NRG Gap Seal and reinforcement fabric. Transition joints between two dissimilar materials such as at beams, columns, window and door frames, etc., should be three-coursed with 323 K-NRG Gap Seal and reinforcement fabric. Center fabric reinforcement so that it extends a minimum of 3” onto both substrates. Refer to local code for flashing requirements on the exterior wall assembly.
Application
322 K-NRG Seal VI is easily applied by brush, roller or spray. Application by airless spray equipment in a single or two-coat application is the preferred method. Work to apply in a continuous, monolithic application. Liquid-applied film should be free of sags or runs. Application should be free of voids when transitioning onto applied flashing membrane to create a uniform air-barrier. Check wet mil thickness regularly with wet-mil gauge to assure uniform coverage meeting required application rate. For best application practices, apply liquid membrane first in even horizontal spray strokes followed by vertical strokes to ensure a uniform and consistent application. Upon completion of work, check for voids. In areas where voids are present simply spray a light coat to cover. Do not spray in excess to cause sagging or running of the material. Apply when ambient air, substrate and material temperatures are all 40°F and rising. Do not apply if ambient air or surface temperatures exceed 120°F.
322 K-NRG Seal VI is not designed for permanent exposure. Product is designed to withstand job site exposure for up to 9 months, however, good construction practice calls for covering as soon as possible. Wherever possible, begin covering membrane on south exposures, followed by remainder of surface. Do not apply if rain is expected within 24 hours after application.
