In case of eye contact, flush thoroughly with large amount of water. Get medical attention if irritation persists. If swallowed, get medical attention immediately.
TYPE OF PAINT
If purchasing paint, an exterior grade latex acrylic paint is the best type of paint to use on ONDURA. DO NOT USE SOLVENT OR OIL BASED PAINTS OR COATINGS on ONDURA material. For best results apply the same color as the original.
Coating integrity and service life will be reduced because of improperly prepared surfaces. The surface should be free of moisture, dirt, loose paint, etc.
Mold and mildew should be removed by scrubbing with a mixture of one-quart household bleach to three quarts of water. Scrub well with a brush and allow solution to remain on the surface for ten minutes before rinsing with clean water. WEAR PROTECTIVE GLASSES OR GOGGLES AND WATERPROOF GLOVES! All areas must be thoroughly dry prior to painting.
DO NOT USE ABRASIVE OR HIGH PRESSURE WATER BLASTERS to clean ONDURA. Low-pressure water (80 psi or less) may be used.
Apply paint only when air and surface temperatures are above 60° F., at least 5° F. above the dew point and relative humidity is below 85%. Coating must not be applied outdoors when it is raining, snowing, sleeting, etc. or when any form of precipitation is imminent. You must stop painting early enough in the day to allow the paint to dry before the sun goes down. Do not paint on windy days.
The paint must be thoroughly mixed before use. The paint may be thinned by adding small amounts of water and mixing until correct consistency for spraying.
Badly weathered areas (bare spots with no paint) should be hand brushed with a coat of paint prior to spray coating. Failure to take this step can give poor results. After spot priming the bare areas, the entire roof should be painted.
Paint may also be hand brushed or mopped (see below).
Paint can be applied by airless spray. We recommend a .026” or .031” spray tip, 600psi-1200 psi, fluid pressure and a 60-mesh filter.
For best results apply two thin coats of paint instead of one heavy coat.
Clean hands, tools, and equipment with warm soapy water. The paint containers should be rinsed out thoroughly and disposed of in a landfill. Empty containers can be a hazard.
