Troubleshooting
Uneven finish or brush/roller marks visible.
Ensure the surface is properly prepared, smooth, and dry. Apply paint evenly, maintaining a 'wet edge' to blend sections. Avoid overworking the paint as it dries.
Paint not adhering well to the surface.
Check that the surface was thoroughly cleaned, dry, and free from loose material, dust, or grease. For very porous or powdery surfaces, a suitable masonry primer or a diluted first coat may be required.
Mould or algae reappearing after painting.
Before painting, ensure all existing mould and algae were completely removed using a fungicidal wash. Address any underlying dampness issues in the wall structure that might be contributing to regrowth.
Coverage is less than expected.
Highly porous or textured surfaces (like some renders or unpainted brick) will absorb more paint. Ensure adequate surface preparation. You may need an additional coat or a primer to achieve stated coverage and finish.
Paint is too thick to apply smoothly.
This water-based paint typically does not require thinning. If application is difficult, ensure the paint is thoroughly stirred. If necessary, a small amount of clean water (no more than 5-10%) can be added for easier application, but this may affect coverage.

Setup, Compatibility & Care Instructions
Surface Preparation (Setup)
Proper preparation is crucial for achieving the best results and ensuring the paint's longevity.
- Clean the Surface: Remove all dirt, loose paint, dust, mould, and grime. Use a stiff brush and appropriate cleaner for mould if present. Rinse thoroughly with water.
- Repair Imperfections: Fill any cracks or holes with a suitable exterior masonry filler. Allow to dry and sand smooth.
- Ensure Dryness: The surface must be completely dry before painting. Allow several days after heavy rain.
- Prime (Optional but Recommended for New/Bare Surfaces): For new or bare, highly porous surfaces, consider applying a suitable masonry primer or a diluted first coat of the paint itself to ensure better adhesion and even absorption.
Compatibility
This paint is specifically designed for exterior masonry surfaces. It is compatible with:
- Brick
- Concrete
- Pebble-dash
- Render
Do not use on wood, metal, plastic, or internal surfaces. Always test a small, inconspicuous area first if unsure about compatibility with an unusual masonry surface.
Application
- Stir Well: Always stir the paint thoroughly before and during use.
- Tools: Apply using a good quality masonry brush for cutting in edges and corners, and a roller for larger flat areas.
- Coats: Apply 2 coats for optimal coverage and durability. In some cases, a third coat may be beneficial on highly textured or previously unpainted surfaces.
- Drying: Allow 4 hours drying time between coats.
Care & Maintenance
- Tool Cleaning: Clean brushes and rollers immediately after use with clean water.
- Storage: Store the paint in a dry, frost-free environment, away from direct sunlight. Ensure the lid is tightly sealed to prevent drying out.
- Surface Cleaning: Once dry, the painted surface is hard-wearing. For routine cleaning, a gentle wash with water and a soft brush can remove superficial dirt. Avoid harsh abrasives or high-pressure washers directly on the painted surface.
