Setup, Compatibility & Care
Preparation
Proper surface preparation is crucial for maximizing the 15-year lifespan of Zinsser Allcoat Exterior Satin. Begin by ensuring the surface is clean, dry, and free from any loose, flaking, or powdery material. *Critically*, if any existing mould or mildew is present, it must be thoroughly removed and the surface treated with an appropriate fungicidal wash before painting. While sanding is often not required for previously painted surfaces (even glossy ones, bitumen, tar, varnish, or creosote), always ensure the existing coating is sound and not peeling. Scrape off any loose paint before cleaning.
Application
Stir the paint thoroughly before and during use to ensure consistent color and finish. Apply in appropriate weather conditions, avoiding extreme heat, cold, or high humidity. Ensure good ventilation where possible. Apply evenly with a brush or roller, taking care not to over-apply. Info needed: Consult the product label for specific recommendations on the number of coats and drying times between applications.
Compatibility
This paint is highly compatible with a wide range of exterior substrates including wood, metal, masonry, uPVC/plastic, cladding, and concrete. It can be applied over most existing solvent or water-based coatings, even problem surfaces like bitumen or creosote, provided they are stable and properly prepared.
Care & Maintenance
Once cured, the painted surface is tough and durable. For best long-term care, regularly clean painted exterior surfaces with a soft cloth or sponge, using a mild detergent and water, to remove dirt, grime, and environmental build-up. Avoid abrasive cleaners or harsh scrubbing that could damage the finish. Store any unused paint in its original container, tightly sealed, in a cool, dry, frost-free environment, away from direct sunlight and extreme temperatures.
