Surface Compatibility: This paint is specifically formulated for exterior use on common masonry surfaces such as brick, concrete, pebble-dash, and render. It creates a perfectly matt surface that looks new for an extended period.
Coverage: A 5L can of this paint typically covers up to 15 square meters on average, making it efficient for refreshing significant areas of your home's exterior.
Application: For the best results, apply the paint using either a brush or a roller. Ensure even application for a consistent finish. Two coats are recommended to achieve full coverage, optimal colour depth, and maximum protective benefits. Allow a minimum of 4 hours drying time between coats to ensure proper adhesion and film formation. The paint's quick-drying nature means it forms a protective barrier against rainwater in just 30 minutes, helping to protect your freshly painted surfaces from unexpected showers.
Long-Term Protection: Its advanced acrylic resin ensures total protection against weathering, including rain, UV radiation, and temperature fluctuations. The flexible film helps prevent the paint from cracking or flaking, even over minor hairline cracks. The integrated algicide and fungicide actively protect the paint film from unsightly mould and algal staining, maintaining the pristine white finish. The Stay Clean technology also works to resist dirt accumulation, keeping your walls looking cleaner for longer.
Setup & Surface Preparation:
Clean the Surface: Thoroughly clean all surfaces to be painted. Remove any loose dirt, dust, grime, flaky paint, mould, or algae using a stiff brush, scraper, and appropriate cleaning agents if necessary. Allow the surface to dry completely.
Repair Imperfections: Fill any large cracks or defects with a suitable exterior filler. Allow to dry and sand smooth.
Priming (If Needed): For very porous or powdery surfaces, a stabilising primer or a thinned first coat of masonry paint (as per manufacturer's instructions) may be beneficial. Info needed: [Consult product label for specific priming recommendations].
Tools: Have a good quality masonry brush or a medium-pile roller ready. Stir the paint thoroughly before use.
Compatibility:
This paint is specifically designed for exterior masonry surfaces including brick, concrete, pebble-dash, and render. Ensure the surface is sound and dry before application. It is not recommended for smooth, non-porous surfaces like glazed tiles or metal without specific priming.
Care & Maintenance:
Routine Cleaning: While the paint contains Stay Clean technology and is mould/algae resistant, periodic gentle cleaning of your exterior walls with water and a soft brush can help maintain their fresh appearance, especially in areas prone to heavier dirt accumulation.
Inspection: Regularly inspect your painted surfaces for any signs of damage or wear, particularly after severe weather. Address minor issues promptly to prevent larger problems.
Storage: Store any leftover paint in a cool, dry place, away from direct sunlight and frost, in its original, tightly sealed container. Do not allow to freeze.
