Preparation:

• All surfaces must be dry and free of dust, dirt, oil, loose granules, gravel or peeling paint and all other foreign matter. Rusty metal must be cleaned with a wire brush and primed with a suitable primer before application of this product. Washing entire surface is recommended for best results. Surfaces with mildew growth or stains must be cleaned with a bleach solution (2 parts water to one part bleach) prior to applying this product. Be certain all surfaces are thoroughly rinsed and dry prior to applying patching material.

Application:

• For best results, apply in early morning hours on clear sunny day. Surface and air temperatures must be a minimum of 65°F and rising. Do not apply if heavy dew or rain is expected within 24-48 hours. Apply with a stiff bristled paint brush. Coat entire damaged area and extend 2” beyond damaged area. Embed Universal Patching Fabric into the repair while wet. Apply second layer of patch, brushing over and into embedded fabric. Allow to cure 24-48 hours and coat entire roof with a Sta-Kool® reflective roof coating. Do not thin. If roof becomes hot (over 100° F) during application, lightly mist roof surface with water spray to prevent coating from drying too fast. Remove any excess or puddling water prior to coating. If roof surfaces become soiled with age, due to the elements, Sta-Kool® 390 can be cleaned with a mild solution of bleach and water. Excess scrubbing should be avoided. If coloring is desired, a typical addition of 3-4 ounces per gallon of Universal colorant can be added, which will result in light pastel colors. Note: Color tinting will disclaim warranty.

Coverage rate:

• Approximately 25 sq. ft. per gal.

Clean-up:

• Clean tools with soap and water.
