Substrate to be coated MUST be dry initially. Once applied, the product can handle a light rain after three hours, assuming temps above 55 degrees. If any moisture is present upon application, there will be blistering. If using a power washer to clean roof, we suggest waiting seven days before coating (if you are applying over a rubber roof). If the roof is lightly cleaned with a brush and minimal water, then coat in two to three days assuming those days were dry.
Roof Preparation and Application Process
We suggest performing an inspection of your roof. Look for any separations in seams. Also, around your joints, AC’s and vents, check for any loose caulk or areas where caulk may be needed. Our Rubex caulk has been field tested to be compatible with our RvRoofMagic, so it will not void the warranty. Be sure any silicone caulk currently on the roof is replaced with the Rubex caulk.
A light power wash, if you have one, is great. Otherwise, use a good bristle brush. The roof must be clean, dry and free of any oil, grease, dirt or loosely adhered coating. Surface should be cleaned with Roof Protect to ensure proper adhesion. We suggest our Roof Protect to thoroughly clean your roof. It was field tested to be compatible with RvRoofMagic and provides a very deep cleaning vs standard cleaners. Roof Protect emulsifies contaminates and provides improved surface preparation by effectively removing oil, grease, mildew, dirt, and other soils from your roofing membrane. It also has a built in mildewcide to kill any living mold spores on your roof prior to application of the RvRoofMagic. You can also use Roof Protect annually to further protect your roof, allowing dirt and grease etc. to be removed, further extending your roof service life.
RvRoofMagic is applied at approximately 50 sq. ft per gallon. The easiest way to accomplish this is to chalk off your roof into 5 X 10 areas. Once you are done filling in one of those areas, you should be finished with a gallon of RvRoofMagic. Be sure your roof is perfectly dry before application. Many customers will tape off their roof with blue painter’s tape to avoid any possible running. RvRoofMagic is ready to use; thinning is not required. Mix for approximately five minutes with an electric drill mixer to allow the solvent to be distributed. Application of the product is with a medium nap roller (3/8 inch) (not a foam roller), and chip brush around corners and vertical surfaces. The product has a three-year shelf life as long as you affix the lid properly, so air does not get in. Average dry time: Dry to touch in 3 - 4 hours. Wait a full 24 hours before traveling. Should you choose to apply a second coat, wait 24 hours. Rain should not be in the forecast on the day you apply the product. However, should a very light rain fall within 2-3 hours of application, the roof is already protected. You may see rain dimples on the surface, depending on the strength of the rain. If seams are not properly adhered, it may cause the tape to bubble up or raise as will a rubber roof that has lost adhesion to the wood substrate. Applying the product too thick will cause it to wrinkle.
FOR EPDM ROOFS ONLY
Apply a "flash coat" (a very light coat) NO MORE THAN 0.75 gal per 100 square feet/1.5 gallon per 200 square feet (12 wet mils). Application rates higher will result in the roof membrane wrinkling. A 24-hour cure time is required before proceeding with main coat. Cooler temps or high humidity may retard your cure times. Then apply the main coat at 1.5 gallons per 100 square feet or 3.0 gallons per 200 square feet (24 wet mils). If flash coat is not completely dry the solvents will continue to gas off and may also cause wrinkling if main coat is put down before flash is dry. If wrinkling does occur, be aware that the membrane will lay back down over time. A note on seasonal changes; after September we suggest at least 36 hours between flash coat and main coat due to environmental conditions. Cooler ambient air temperatures and active dew points play a factor in the flash coat as they will also retard cure times.
This product is for outdoor use. If you choose to use it indoors, you will need a Niosh respirator, available at Home Depot or Uline. As the product begins to dry any brush or roller marks will disappear and what is left is a seamless coating. It will be as if someone just installed a custom fit piece of membrane, just for your RV. Apply today and drive away tomorrow! It’s that easy. Clean-up is with Xylene available at any paint store.
