Product catalog summary
Description: Karnak 405 Bond-N-Shield is a 100% elastomeric acrylic co-polymer emulsion designed as a base coat for asphalt surfaces. It offers excellent adhesion and includes stain blockers to prevent asphalt bleed-through, resulting in a brighter white finish. It also has improved resistance to water blistering in temporary ponding areas compared to traditional acrylic coatings.
Uses: This product is used as a base coat before applying topcoats like 501 Elasto-Brite, 529 Renu-White, and 535QS Enviro-Lastic on built-up roofs aged at least 90 days and SBS and APP modified membranes weathered for 30 days.
Surface Preparation: Surfaces must be dry, clean, and free of contaminants. Power wash with 799 Wash-N-Prep Roof Cleaner or a TSP substitute. Repair any cracks or holes and replace wet insulation. New BUR surfaces must age 90 days, and SBS/APP membranes should weather 30 days before coating.
Application: Mix lightly before application. Apply using a brush, spray, or roller. For temperatures above 90°F, apply in multiple thin coats. Spray applications should use a 50% over-spray pattern, while brush/roller applications should maintain a consistent direction.
Coverage Rate: Apply at 1.5 gallons per 100 sq. ft. Allow 6-24 hours to dry before applying the finish coat. The total dry mil thickness should be 20 to 24 mils.
Care of Tools: Clean tools with water while wet or with Karna-Klean or xylene when dry, following safety precautions.
Physical Properties: Weight per Gallon: 11.4 lbs; Solids by Weight: 63%; Solids by Volume: 49%; Color: Light Blue; Hardness Shore A: 60; Elongation: 800%; Tensile Strength: 100 PSI; Weathering: Excellent; Permeability: 3.0 Perms; VOC Content: 47 gm/L.
Caution: Do not apply if rain is imminent. Ensure coating is dry before water exposure. Store in a heated room and keep covered. Do not thin. Avoid prolonged skin contact and dispose of safely. Ensure positive drainage as per NRCA guidelines.

405 Bond-N-Shield Base Coat-1

(Asphalt Surface Base Coat) DESCRIPTION: Karnak 405 Bond-N-Shield is a 100% elastomeric acrylic, co-polymer emulsion, specifically designed as a base coating that will provide excellent adhesion to asphalt surfaces. The coating contains stain blockers that prevent asphalt bleed thru thus producing a brighter white coating over these surfaces. Technological advances in the Karnak laboratory also give this acrylic coating improved water blistering resistance in temporary ponding areas versus traditional acrylic coatings. USES: 405 Bond-N-Shield is intended for use as a base coat prior to the application of, 501 Elasto-Brite, 529 RenuWhite and 535QS Enviro-Lastic, topcoats on built-up roof surfaces that have aged a minimum of 90 days and SBS and APP smooth and granular modified membranes that have weathered 30 days. SURFACE PREPARATION: Surfaces to be coated should be dry, clean, and free of dirt, dust, grease, oil and loose paint. Power wash surfaces with 799 Wash-N-Prep Roof Cleaner or TSP substitute and water. Wash roof surfaces with a minimum of 2000 psi. Taking all necessary precautions to avoid damage to the roof system. Patch and repair cracks or holes with Karna-Flex WB and Resat-Mat or Poly-Mat or appropriate sealants or caulking materials. All wet insulation should be removed and replaced with like materials. New BUR roof surfaces must age a minimum of 90 days before coating. SBS and APP modified bitumen membranes should weather 30 days before coating. APPLICATION: Mix lightly prior to application of the coating. 405 Bond-N-Shield 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. 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. BRUSH / ROLLER APPLICATION: Brush / roller application should be done applying the coating in the same direction. Apply the finish coat perpendicular to 405 Bond-N-Shield. COVERAGE RATE: Apply 405 Bond-N-Shield over the surface at the rate of 1.5 gallons per 100 sq. ft. Allow dry 6-24 hours then apply the selected finish coating. The total dry mil thickness of 405 Bond-N-Shield and finish coating should be 20 to 24 mils. Coverage will vary depending on the surface to be coated. CARE OF TOOLS: While material is still wet, tools may be cleaned with water. Dry coating can be cleaned with Karna-Klean or xylene or similar solvent, taking the necessary precautions when handling flammable materials. 330 CENTRAL AVENUE, CLARK, NJ 07066 732-388-0300 • 800-526-4236 • FAX: 732-388-9422 WEB: http://www.karnakcorp.com
