  • 406 Tru-Grip Base Coat
    • Self-priming acrylic base coat with marine green indicator color, provides superior adhesion
    • Blocks plasticizer migration for coating durability, improves blister resistance in ponding areas
    • Coverage: 1.5 gallons per 100 sq. ft.
    • 5-gallon, 55-gallon...

  • DESCRIPTION: 406 Tru-Grip is a 100% acrylic elastomeric co-polymer emulsion, specifically designed as a base coating for adhesion to weathered TPO, Hypalon, and PVC roofing membranes. When applied to a suitably cleaned, weathered TPO or PVC roof and top coated with a durable acrylic elastomeric topcoat such as 535 QS Enviro-Lastic, 505HS Mohave Coat, 501 Elasto-Brite or 529 Renu-White, the basecoat can extend the life of the existing roof membrane. The technology used in 406 Tru-Grip enables the coating to have very good adhesion and resistance to blistering when applied to weathered TPO and PVC.

    USES: Elastomeric Roof Coating Systems that use 406 Tru-Grip as the basecoat are ideal for use over aged TPO, Hypalon and PVC roofing membranes that have been weathered at least four years.

    SURFACE PREPARATIONS: Weathered TPO and PVC surfaces accumulate dirt over time and must be cleaned prior to coating with 406 Tru-Grip. Recommended application temperature is 40°F to 120°F. It is particularly important to effectively clean ponded water areas where greater accumulations of dirt can occur. For optimal adhesion and water resistance, water alone is insufficient to clean weathered TPO and PVC membranes properly. Suitable liquid cleaners such as 507 SPC Primer/Wash  and 799 Wash-N-Prep  Roof  Cleaner solutions with water can be spray applied over the entire surface followed by a thorough power washing. Power wash roof surfaces using a pressure of 2,500 to 3,500 psi with a wide fan tip. All residual cleaning agents must be removed, otherwise they will interfere in the adhesion of 406 Tru-Grip. When using liquid cleaning solutions, please refer to the specific product label and MSDS for safe handling information and proper use instructions. 

    APPLICATION: Mix lightly prior to application of the coating. 406 Tru-Grip may be applied by brush, spray equipment or roller. For applications in higher temperatures (above 90 °F) KARNAK recommends application in multiple thin coats to prevent trapped moisture problems. Commencement of work by the contractor implies his approval of the deck surface.

    ROLLER / BRUSH APPLICATION: Apply with a 3/4" – 1-1/4” nap roller or soft roof brush.

    SPRAY APPLICATION: Utilize a standard paint spray pump or airless spray pump. Equipment manufacturer should be consulted for more complete information. Spray application should be done with a 50% over-spray pattern.

    COVERAGE RATE: Apply 406 Tru-Grip over the surface at the rate of 1.5 gallons per 100 sq. ft. (24 wet mils).  Allow to dry 8-24 hours then apply the selected finish coating. The total dry mil thickness of 406 Tru-Grip and finish coating should be 20 to 24 mils. Coverage will vary depending on the surface to be coated.

    USES: 529 Renu-White is designed for application over built-up roof (BUR) surfaces that have aged a minimum of 90 days, SBS and APP granular and smooth modified membranes that have weathered a minimum of 30 days, aged aluminum coated roofs as well as metal roofs.  Also may be applied to above grade vertical surfaces such as concrete, concrete block, brick, stucco and wood.  529 Renu-White may be used for application over applicable base coats 405 Bond-N-Shield, 406 Tru-Grip, 404 Corrosion Proof Base and 407 EPDM & SPF as a base coat for EPDM.  
    SURFACE PREPARATIONS: All surfaces to be coated should be in sound condition and thoroughly cleaned and free of oil, grease, dust, dirt, debris and loose coating. Recommended application temperature is 40°F to 120°F. Pressure wash with 799 Wash-N-Prep Roof Cleaner and water. Rinse surfaces well to remove all soapy residues and allow to dry completely. Metal surfaces must be wire brushed down to clean and stable surface. Repair all roof surfaces with appropriate materials prior to coatings. Read the MSDS before using.  
    APPLICATION: Recommended use is for application over one of KARNAK’s 400 series substrate specific base coats or directly to the substrate in a two coat application. Mix lightly prior to application of the coating. 529 Renu-White may be applied by brush, spray equipment or roller.  Allow first coat to dry 8 to 12 hours before application of the second coat. Apply each coat in one direction with the second coat applied perpendicular to the first/base coat.  Apply when temperatures are 40ºF and rising but not over 120ºF.  Do not apply when rain is expected during or within 24 hours after application.  For applications in higher temperatures (above 90 °F) KARNAK recommends application in multiple thin coats to prevent trapped moisture problems. Commencement of work by the contractor implies his approval of the deck surface. 
    ROLLER / BRUSH APPLICATION: Apply with a 3/4" – 1-1/4” nap roller or soft roof brush perpendicular to the first coat / base coat for proper protection.  
    SPRAY APPLICATION: Utilize a standard paint spray pump or airless spray pump. Equipment manufacturer should be consulted for more complete information. Spray application should be done with a 50% over-spray pattern.

  • 321 K-NRG Seal VP / Air Barriers
    • Liquid-applied & elastomeric
    • Vapor permeable air & water barrier
    • Passes NFPA 285 Fire Test
    • 5-gallon, 55-gallon...

  • DESCRIPTION: 321 K-NRG Seal™ VP is a liquid applied, elastomeric membrane designed to provide a vapor permeable 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, which resists air leakage. 321 K-NRG Seal VP incorporates antimicrobial technology to produce a mold resistant membrane that passes stringent NFPA 285 Fire Test.  
    USES: 321 K-NRG Seal VP is a liquid applied membrane used to construct high performance building envelope air & water barrier membrane assemblies requiring vapor permeability.  When combined with KARNAK’s sealants and accessories, 321 K-NRG Seal VP forms a complete vapor-permeable wall airbarrier system.  Commonly used on variety of wall substrates and sheathing prior to installation of exterior cladding.  
    FEATURES, BENEFITS AND ADVANTAGES:  Monolithic, vapor permeable, elastomeric membrane for above-grade wall applications  Easily applies by spray application, roller or brush  Integral mold resistant formulation  High water vapor permeance provides “breather” characteristics  Excellent adhesion to most construction surfaces such as exterior gypsum boards, CMU, concrete, stone, wood and metal – can be applied to damp concrete  Passes NFPA 285 Fire Test – Exceeds ASTM E2178 and ASTM E2357 
    SURFACE PREPARATIONS: 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 (except damp concrete).  New concrete should be cured a minimum of 7 days before 321 K-NRG Seal VP 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: 321 K-NRG Seal VP 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. 
    321 K-NRG Seal VP 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. 
    COVERAGE RATE:   Smooth Surfaces such as exterior gypsum sheathing or formed concrete apply 2.5 gallons per 100 square feet to give a wet film thickness of approximately 40 mils (20 mils DFT) depending on texture and porosity of surface.  Rough Surfaces such as CMU apply 3 gallons per 100 square feet to give a wet film thickness of approximately 48 mils (24 mils DFT) depending on texture and porosity of surface.  Apply using airless spray equipment, 1-1/4” nap roller or brush.

  • 97 Fibered Aluminum Roof Coating
    • Fibered aluminum for heavy duty service
    • Extends the life of asphalt and modified bitumen membranes
    • Coverage: 1-1.5 gallon per 100 sq. ft.
    • 1-gallon, 5-gallon...

  • DESCRIPTION: 97 Fibered Aluminum Roof Coating is made of selected asphalts and pigment flakes of pure aluminum blended with refined solvents and reinforcing fibers for heavy duty service. When 97 Fibered Aluminum Roof Coating is applied to the roof, the aluminum flakes leaf to the surface providing a reflective metallic shield over the base of the coating. 
    A. The asphaltic oils in the roof are protected from harmful intense rays of the sun by the reflective properties of the aluminum. Over 50% of the sun’s rays are reflected by this aluminum shield, thereby preventing these oils from being “cooked” out of the roof substrate.  The coating, therefore, retains its resilient characteristics and will not prematurely crack or dry out. 
    B. During the hot summer months, 97 Fibered Aluminum Roof Coating will help reduce indoor building temperatures and improve inside living and working conditions. Be reflecting the sun’s rays and reducing roof surface temperatures.  
    One coat of 97 Fibered Aluminum Roof Coating will extend the life of modified bitumen membrane, not only by limiting fire-spread, (as indicated by the U.L. Class “A” Rating) but its high aluminum content and excellent reflectivity afford solar protection and weather durability. 97 Fibered Aluminum Roof Coating is U.L. Class A rated over specified Modified Bitumen Systems, UL Listing #Rl2l99 (N). 
    USES: 97 Fibered Aluminum Roof Coating helps reduce indoor building temperatures. It’s ideal for use on modified bitumen membranes, metal corrugated roof decks, steep asphalt roofs that have aged for 90 days, or any KARNAK emulsion roof coating that has been allowed to cure for 3-5 days.  
    SURFACE PREPARATIONS: Prepare all surfaces by sweeping clean of dust, dirt, loose rust, oil and loose particles. Recommended application temperature is 50°F to 120°F. Repair all cracks and blisters by spreading KARNAK 19 Ultra Rubberized Flashing Cement over the damaged area, then embed KARNAK Asphalt Cotton, Fiberglass, Poly-Mat or Resat-Mat reinforcement and apply another coat of KARNAK 19 Ultra Rubberized Flashing Cement over the entire patch. New asphalt roof surfaces should weather a minimum of 90 days before being coated over with 97 fibered Aluminum Roof Coating. However, 97 Fibered Aluminum Roof Coating can be coated on roofs 3 to 5 days after KARNAK asphalt emulsion roof coatings have been applied. Badly weathered or alligatored asphalt surfaces should be primed with KARNAK 100 Non-Fibered Emulsion Primer or 220 Fibered Emulsion Roof Coating prior to coating with 97 Fibered Aluminum Roof Coating. Allow emulsion primer/coating to cure a minimum of 3-5 days before application of aluminum roof coating. 
    APPLICATION: 97 Fibered Aluminum Roof Coating should be spread uniformly over the roof surface. Care should be taken not to overwork the coating during application. This could have a damaging effect on the leafing of the aluminum. Pour the correct amount of aluminum roof coating to cover a given area and work it in one direction. Be sure to mechanically mix the aluminum roof coating thoroughly before using. 97 Fibered Aluminum Roof Coating can be applied with a soft roof brush, roller or spray. Discoloration will occur in areas where 19 Ultra Rubberized Flashing Cement is not allowed to dry a minimum of 60 days.  After 60 days, recommended application temperatures are 50˚F and rising. 
    COVERAGE RATE: Apply at 1 to 1.5 gallons per 100 sq. ft. (16-24 wet mils).  DO NOT THIN.    
    CAUTION: Do not use near open flame.  Avoid breathing solvent fumes and prolonged contact with skin. Do not take internally. If swallowed, do not induce vomiting.  Call a physician immediately. Keep out of reach of children.  Store in a heated room and keep container covered when not in use. Do not thin. Dispose of in an environmentally safe manner. Cover air intakes during application and while drying.  Exterior use only.  
    KARNAK recommends coating torch-applied modified bitumen membranes as soon as possible after the membrane is installed. KARNAK’s experience, laboratory and field tests, as well as NRCA, RCMA and ARMA reports, indicate that aluminum roof coating will reduce the combined effects of ultraviolet rays, heat and moisture, which, especially on APP modified bitumen, enhance exudation that can cause discoloring and delamination of any surface coating. After 60 days, recommended application temperatures are 50˚F and rising. Coating must not come in contact with any type of moisture within 2448 hours after application. 
    Cold-process systems and coatings, either emulsion or solvent-based, should only be installed on decks with positive drainage.  Per NRCA (National Roofing Contractors Association), “The criteria for judging proper slope for drainage is that there be no evidence of standing water on a deck 48 hours after it stops raining.” 
    PACKAGING: Available in 5-gallon pails, 1-gallon cans and 55-gallon drums.

  • 169 Non-Fibered Aluminum Roof Coating
    • Non-fibered aluminum for smooth asphalt roof surfaces
    • Extends the life of asphalt and modified bitumen membranes
    • Coverage: 0.5-1 gallon per 100 sq. ft.
    • 1-gallon, 5-gallon...

  • DESCRIPTION: 169 Non-Fibered Aluminum Roof Coating is a formulation of selected asphalts, refined solvents and fine aluminum flakes. When the coating is applied to the roof, the aluminum flakes leaf in overlapping parallel layers, forming a reflective, metallic shield over the base material. 
    The combination of these two protective materials, aluminum and asphalt, by the exclusive KARNAK process results in a self-protecting roof coating with longer-lasting moisture and heat-resistant properties. 169 Non-Fibered Aluminum Roof Coating remains permanently bonded to the roof substrate, thus assuring longer roof life with subsequent savings on roof maintenance. 
    The asphaltic oils in the roof are protected from the intense rays of the sun by the reflective properties of the aluminum. Most of the sun’s rays are reflected by this aluminum shield, thereby preventing these oils from being “cooked” out of the roof substrate. The coating, therefore, retains its resilient characteristics and will not prematurely crack or dry out. During the hot summer months, 169 Non-Fibered Aluminum Roof Coating will help reduce indoor building temperatures and improve inside living and working conditions. 169 Non-Fibered Aluminum Roof Coating prevents the sun’s rays from penetrating the roof coating and passing the heat into the building interior. 
    USES: 169 Non-Fibered Aluminum Roof Coating is ideal for use on modified bitumen membranes, metal corrugated roofs and steep asphalt roofs. New BUR asphalt roofs should weather a minimum of 90 days before being coated with 169 Non-Fibered Aluminum Roof Coating.  However, it can be coated on roofs 3 to 5 days after KARNAK asphalt emulsions roof coating has have been applied.  
    SURFACE PREPARATIONS: All surfaces should be clean, dry and free from oil, grease, dust, dirt, loose rust, loose paint or other foreign matter. Recommended application temperature is 50°F to 120°F. Badly weathered or alligatored asphalt roof surfaces should be primed with KARNAK 100 Non-Fibered Emulsion Primer or 220 Fibered Emulsion Roof Coating prior to coating with 169 Non-Fibered Aluminum Roof Coating. Allow emulsion coating to cure a minimum of 3-5 days before application of aluminum roof coating. 
    APPLICATION: 169 Non-Fibered Aluminum Roof Coating should be spread uniformly over the roof surface. Care should be taken not to overwork the coating while applying. This will have a damaging effect on the leafing action of the aluminum. Be sure to mechanically mix the aluminum roof coating thoroughly before using. 169 Non-Fibered Aluminum Roof Coating can be applied with a soft roof brush, roller or spray. 
    COVERAGE RATE: Apply at 0.5 to 1 gallon per 100 sq. ft.  (8-16 wet mils).  DO NOT THIN.    
    CAUTION: Do not use near open flame.  Avoid breathing solvent fumes and prolonged contact with skin. Do not take internally. If swallowed, do not induce vomiting.  Call a physician immediately. Keep out of reach of children.  Store in a heated room and keep container covered when not in use. Do not thin. Dispose of in an environmentally safe manner.
