To finish strong you need a class-leading durable architectural coating with hydrophobic properties formulated with acrylic polymers with increased durability and film formation. DuraCote HP is made for coating an extensive variety of substrates with class-leading durability and develops hydrophobic properties that bead rainwater, keeping the building cleaner.

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 DuraCote 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 DuraCote HP.
*White Base value, may vary by base.
Aluminum: Wash to remove any oil, grease, or other surface contamination. All corrosion must be removed with sandpaper, steel wool, or other abrading method.
Cement Composition Siding/Panels: Remove all dirt, dust, grease, oil, loose particles, laitance, foreign material, and peeling or defective coatings. Allow the surface to dry thoroughly. If the surface is new, test it for pH, if the pH is higher than 9, prime with Primecoat Primer if not pre-primed.
Masonry, Concrete, Cement, Block: All new surfaces must be cured according to the supplier’s recommendations—usually about 30 days. Remove all form release and curing agents. Rough surfaces can be filled to provide a smooth surface. If painting cannot wait 30 days, allow the surface to cure 7 days and prime the surface with Primecoat Primer. Cracks, voids, and other holes should be repaired with an elastomeric patch or sealant.
Steel: Rust and mill scale must be removed using sandpaper, steel wool, or other abrading method. Bare steel must be primed the same day as cleaned.
Stucco/EIFS/Acrylic Textured Finishes: Remove any loose stucco, efflorescence, or laitance. Allow new stucco to cure at least 15 days before painting. If painting cannot wait 15 days, allow the surface to dry 5-7 days and prime with Primecoat Primer (pH of 13 or less). Repair cracks, voids, and other holes with an elastomeric patch or sealant.
Vinyl: Clean the surface thoroughly by scrubbing with warm, soapy water. Rinse thoroughly.
Wood, Plywood, Composition Board: Sand any exposed wood to a fresh surface. Patch all holes and imperfections with a wood filler or putty and sand smooth. Prime with Primecoat.
Caulking: Gaps between windows, doors, trim, and other through-wall openings can be filled with the appropriate caulk after priming the surface.
SURFACE PREPARATION PRECAUTIONS
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.

Apply two coats of DuraCote 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.
