Recommended Unit Preparation:
EPDM CLEANER/ACTIVATOR is designed for use on rubber roofing surface only and may damage other exterior parts of RV. It is highly recommended that you secure plastic sheeting over entire sidewalls as well as front and rear endcaps to protect them from possible damage. If EPDM CLEANER/ACTIVATOR contacts any surface other than the roof, it should be rinsed immediately.
Surface Preparation:
Remove heavy deposits of dirt, leaves, pine needles and other debris using a broom or air blower. Any rocks, branches, or other large objects should also be removed. EPDM CLEANER/ACTIVATOR can be applied directly over EPDM surfaces containing residual amounts of dirt, dust and other contamination.
Application:EPDM CLEANER/ACTIVATOR is a ready-to-use material. It can be applied using a Hudson-type agricultural sprayer. Safety glasses with side shields and latex gloves are recommended when transferring EPDM CLEANER/ ACTIVATOR from the shipping container to the sprayer. Spray a fine mist that leaves roof damp. Adjust spray for weather conditions if necessary. If EPDM CLEANER/ACTIVATOR is running off the roof, you have used too much. If using a Hudson sprayer, adjust the spray nozzle to achieve a uniform spray pattern with a 3 to a 4-foot arc. Application rate is 125 sq. ft. per quart over new or existing surfaces. Do not apply below 40°F (4°C).
Allow EPDM CLEANER/ACTIVATOR to stand a minimum of 15 minutes to wet out and react with the EPDM surface. RINSE WITH CLEAN WATER. For best results, use a minimum 2,000 psi pressure washer. Using a 15” spray pattern, begin the power rinse at the lowest point on the roof and work upwards, keeping the pressure washer tip within 12″ of the EPDM surface. Once the highest point on the roof is reached, work down again with a final rinse to remove any excess dirt or debris from the roof. If a power washer is unavailable, use a medium bristle brush, working smaller area at a time, rinsing thoroughly to be sure all cleaner/activator has been removed.
After cleaning, the roof should be “white” in color, which is an indication that the surface has been chemically altered.
NOTE: Entire project must be completed in one day; including cleaner/activator application, rinsing and 2 coats of acrylic coating, each dry to the touch.
Clean equipment with water and biodegradable detergent. Purge the water from the pump.
DANGER: CAUSES SEVERE IRRITATION OF THE EYES, CAUSES GASTROINTESTINAL IRRITATION, NAUSEA, VOMITING AND DIARRHEA, BURNS MOST SKIN. Prolonged or repeated breathing of vapor or spray mist may be harmful. Use a respirator for protection from vapor or spray mist. Wear chemical resistant gloves, splash-proof goggles, and rubber overshoes. Avoid eye and skin contact. Do not take internally. Wash thoroughly after handling and before eating or smoking. Keep container closed when not in use.
FIRST AID: If swallowed, do not induce vomiting. Call a physician immediately. Never give anything by mouth to an unconscious person. In case of contact, flush eyes and skin with plenty of water for 15 minutes while removing contaminated clothing and shoes. For eye contact, consult a physician. If skin irritation persists, get medical attention. Wash clothing before reuse. Clean contaminated shoes. If inhaled, move to fresh air. Give oxygen or artificial respiration as needed. Call a physician immediately.
