Often times your roof gets neglected, as it is unseen. Unless you physically up onto the roof, you won’t know if there is damage, cracks, splits or blocked drainage unless it begins leaking inside the building. If you wait until this happens, it’s often too late and you are left rushing to choose the fastest roofing option to solve the leaking water as quickly as possible. We want to encourage you to be proactive so you can save yourself the extra cost, time, and stress. Summer is a perfect time to find a roof coating that fits your roofs particular needs. You may need a knowledgeable experienced roofing contractor for advice if a coating is really needed? National Roofing LEAK REPAIR are the ones to call (713) 789-6400

USES
501 Elasto-Brite is designed to be applied directly over built-up 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. 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 405 Bond-N-Shield, 406 Tru-Grip, 404 Corrosion Proof Base and 535 QS Enviro-Lastic as a base coat for EPDM.Meets ASTM D-6083.
SURFACE PREPARATION
Surfaces to be coated should be dry, clean, free of dirt, dust, grease, oil and loose paint. Power wash surfaces with 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 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. 501 Elasto-Brite or subsequent base coats should be dry prior to application of 501 Elasto-Brite.
APPLICATIONMix lightly prior to application of the coating. 501 Elasto-Brite may be applied by brush, spray equipment or roller.
SPRAY APPLICATIONUtilize 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 APPLICATIONBrush / roller application should be done perpendicular to the first coat/base coat for proper protection.
ARCHITECTURAL COLORSWhite and gray are standard colors. Tan, Patina Green and Terra Cotta Red are available in quantities of 210 gallons minimum.
Karnak #502 RC-W Elasto-Kote is a highly elastic solvent based thermoplastic exterior waterproof coating. The coating has excellent color stability, weatherability and flexibility. Karnak #502 RC-W Elasto Kote has outstanding surface appearance and durability against salt spray, acid rain and ultra-violet sunlight.
Elastomeric roof coating systems offer multiple advantages over traditional roofing options as they require less time for installation and application, reduced costs, lengthened roof life, and these roof coating systems are sustainable - allowing you to re coat your roof every 10-15 years to avoid a roof tear-off forever. Dry, warm weather is the most ideal weather condition for application of a roof coating system, making the summer an excellent time to restore your roof.Traditional roofing requires a roof tear-off after two roofs have been installed on a building. This is a building code law that is enforced and must be abided by; however, installing a roof coating system allows you to avoid a roof tear-off (indefinitely, might I add) as these systems do not bare the weight of a traditional roof, allowing roof coating systems to be exempt from this code. When you restore your roof with one of our roofing systems you save yourself time - no business closures, no tear-off stages, and an easy application process. You also save yourself money - there are no landfill fees and shorter construction time because the roof coating system is spray applied directly over your existing roof membrane. Business is conducted as usual so you don't lose production or sales efforts. Another advantage to roof coating systems is they are seamless. When applied, these systems are sprayed onto your rooftop allowing the coating to spread and bond together; filling gaps, seams, joints and cracks, covering necessary areas around pipes, drains and equipment creating a durable, monolithic, custom installed, watertight roofing system particularly created for your individual roof.
DESCRIPTION:
Karnak #502 RC-W Elasto-Kote is a highly elastic, thermoplastic rubber based,
single component exterior waterproofing coating.
USES:
Karnak #502 RC-W Elasto-Kote is intended for use on metal roofs, spray
polyurethane foam roofs, EPDM, TPO, and most PVC roof membrane. Also good
over previously coated surfaces as well as for coating concrete, concrete block,
brick, cinder block, stucco and wood. Do not apply over asphaltic surfaces.
PVC and TPO roofs should be at least 4 years old before coating.
SURFACE PREPARATION:
All roof surfaces to be coated should be clean and free of dirt, dust flaking and
pitting rust, grease, oil, and loose paint. New masonry surfaces should be allowed
to cure 30 days before application of coating. EPDM roof surfaces should be
cleaned with #507 SPC Primer/Wash. Other single ply membranes should be
cleaned with #799 Wash-N-Prep Roof Cleaner and water. Patch and repair all
seams, flashings with Karna-Flex and Resat-Mat or 550 Patch-N-Go or appropriate
sealants and caulking materials. Contact Karnak Technical Services at 800-526-
4236 for questions regarding surface preparation.
APPLICATION:
Karnak #502 RC-W Elasto-Kote Base and Finish may be applied by brush, roller or
spray equipment.
ARCHITECTURAL COLORS:
Standard colors are White and Gray. Tan, Terra Cotta Red and Patina Green
available in quantities of 210 gallons minimum.
COVERAGE RATE:
Apply Karnak #502 RC-W Elasto-Kote Base at the rate of 1.25-1.5 gallons per 100
sq. ft. Allow base to dry 24 hours before applying #502 RC-W Elasto-Kote Finish at
the rate of 1.25-1.5 gallons per 100 sq. ft. Coverage rate will vary due to texture
and porosity of the surface. Film thickness should be approximately 20-24 mils dry.
Karnak #502 RC-W Elasto-Kote Finish will take approximately 24 hours to cure.
EPDM roofs should first be coated with 502 RC-W Base at the rate of 0.5 gallons per
100sq. ft. followed by two coats of 502- RC-W Elasto-Kote Finish at 1-1.5 gallons
per 100sq. ft. per coat.
CARE OF TOOLS:
Tools may be cleaned with xylol, mineral spirits, lacquer solvents or Karna-Klean.
Take necessary safety precautions when handling flammable materials.
