Approved Surfaces³

Stucco/EIFS/Textured Acrylic Finishes¹
Cement Composition Siding/Panels
Aluminum & Aluminum Siding²
Vinyl Siding
Others approved in writing

1. Surfaces with a pH greater than 9 must be primed with a high pH-resistant coating such as Master Wall® Primecoat Primer or other acrylic-finish compatible primer.
2. On large expanses of metal siding, the air, surface, and material temperatures must be 50°F or higher.
3. Standard latex primers cannot be used below 50°F. See specific primer label for that product’s application limitations. Knots and some woods, such as redwood and cedar, contain a high amount of tannin, a colored wood extract. If applied to these bare woods, the first coat of SuperiorCote HP Coating may show some staining, but it will be trapped in the first coat. A second coat will uniform the appearance. If staining persists, spot prime severe areas with 1 coat of Exterior Oil-Based Wood Primer then topcoat with SuperiorCote HP.

*White Base value, may vary by base.

Application Procedure

WARNING! Removal of old paint by sanding, scraping or other means may generate dust or fumes that contain lead. Exposure to lead dust or fumes may cause brain damage or other adverse health effects, especially in children or pregnant women. Controlling exposure to lead or other hazardous substances requires the use of proper protective equipment, such as a properly fitted respirator (NIOSH approved) and proper containment and cleanup. For more information, call the National Lead Information Center at 1-800-424-LEAD (in US) or contact your local health authority.

Remove all surface contamination by washing with an appropriate cleaner, rinse thoroughly and allow to dry. Scrape and sand peeled or checked paint to a sound surface. Sand glossy surfaces dull. Sand hard surfaces, such as metal, to provide better adhesion. Seal stains from water, smoke, ink, pencil, grease, etc. with the appropriate primer/sealer.

Mildew: Remove before painting by washing with a solution of 1 part liquid bleach and 3 parts water. Apply the solution and scrub the mildewed area. Allow the solution to remain on the surface for 10 minutes. Rinse thoroughly with water and allow the surface to dry before painting. Wear protective eyewear, waterproof gloves, and protective clothing. Quickly wash off any of the mixture that comes in contact with your skin. Do not add detergents or ammonia to the bleach/water solution.

When the air temperature is at 38°F, substrates may be colder; prior to painting, check to be sure the air, surface, and material temperature are above 38°F and at least 5°F above the dew point. Avoid using if rain or snow is expected within 2-3 hours.

Do not apply at air or surface temperatures below 38°F or when air or surface temperatures may drop below 38°F within 48 hours. No reduction necessary.

Brush: Use a nylon/polyester brush.
Roller: Use a high quality polyester roller cover, 3/8” to 3/4” nap.
Pressure ………………………….. 2000 psi
Tip ……………………………… .015″-.019″

Apply two coats of SuperiorCote HP for proper performance. Hydrophobic properties will not develop immediately and are UV dependent. It may take up to 30 days before hydrophobic properties are visible.

Clean spills, spatters, hands and tools immediately after use with soap and warm water. After cleaning, flush spray equipment with mineral spirits to prevent rusting of the equipment. Follow manufacturer’s safety recommendations when using mineral spirits.

Mildew Resistant This coating contains agents which inhibit the growth of mildew on the surface of this coating film. Protect from freezing. Non-photochemically reactive.

Use only with adequate ventilation. To avoid overexposure, open windows and doors or use other means to ensure fresh air entry during application and drying. If you experience eye watering, headaches, or dizziness, increase fresh air, or wear respiratory protection (NIOSH approved) or leave the area. Avoid contact with eyes and skin. Wash hands after using. Keep container closed when not in use. Do not transfer contents to other containers for storage. FIRST AID: In case of eye contact, flush thoroughly with large amounts of water. Get medical attention if irritation persists. If swallowed, call Poison Control Center, hospital emergency room, or physician immediately. WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. DO NOT TAKE INTERNALLY. KEEP OUT OF THE REACH OF CHILDREN.
