Uses
505HS Mohave Coat is designed to be applied directly over built-up asphalt roof surfaces that have aged a minimum of 90 days, SBS and APP granular modified membranes and smooth surface APP membranes that have weathered a minimum of 30 days as well as metal roofs and SPF foam systems. Also, for use on above grade vertical surfaces such as concrete, concrete block, brick, stucco, metal and wood. May also be used for application over applicable base coats 404 Corrosion Proof Base Coat, 405 Bond-N-Shield, 406 Tru-Grip, and 407 EPDM & SPF Base Coat.

Preparation & Application
SURFACE PREPARATION:
Surfaces to be coated should be dry, clean, free of dirt, dust, grease, oil and loose paint. Recommended application temperature is 40°F to 120°F. Power wash surfaces with 799 Wash-N-Prep 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 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. Newly installed cold-process, hot-applied and torched-applied modified bitumen membranes should age 30 days before coating. Allow fresh masonry to cure a minimum of 30 days before application. 505HS Mohave Coat or subsequent base coats should be dry prior to application of a finish coat of 505HS Mohave Coat.
APPLICATION:
Recommended use is for application over one of KARNAK’s 400 series substrate-specific base coats. Mix lightly prior to application of the coating. 505HS Mohave Coat 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 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 or 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 heavy-duty professional airless spray pump. Equipment manufacturer should be consulted for more complete information. Spray application should be done with a 50% overspray pattern.
COVERAGE RATE:
Apply in a single coat over applicable 400 series base coat at the rate of 1.5 gallons per 100 sq. ft. (24 wet mils) or apply direct to substrate in a two-coat application at the rate of 1.5 gallons per 100 sq. ft. per coat (Total of 3 gallons per 100 sq. ft.). This will achieve a dry mil thickness of 20 to 24 mils. Coverage will vary depending on the surface to be coated.
ARCHITECTURAL COLORS:
Standard colors: White
Standard colors for western states only: Desert tan and adobe brown
Specialty colors: Patina green, forest green, terra cotta red, red, cement gray and khaki tan. All require minimum order of 350 gallons.
Caution / Care of Tools
Do not apply when rain is imminent. Coating must be dried before exposure to water. Store in a heated room and keep container covered when not in use. Do not thin. Keep out of reach of children. Avoid prolonged contact with skin. Dispose of in an environmentally safe manner. Cover air intakes during application and while drying.
COLD-PROCESS SYSTEMS AND COATING, 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 THE DECK 48 HOURS AFTER IT STOPS RAINING.”
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.
