Grean Boss 4 Litre

Protect your home and outdoor spaces with Grean Boss, the trusted product designed to protect roof tiles from surface degradation. Surface deposits not only spoil the appearance of your roof tiles, but can be the leading cause of deterioration, holding moisture, lifting tiles, blocking gutters and downpipes. If left untreated, the lifespan of your roof can be significantly reduced. Our advanced formula is safe to use on clay, concrete, and slate roof tiles, including flat roofs. It penetrates deeply to break down surface deposits and green deposits on all hard surfaces, allowing the rain to wash away over time. Versatile and easy to use, Grean Boss can also be applied to patios, garden paths, tarmac, and resin driveways for year-round protection. Ensuring surfaces around your property are safe to walk on. Coverage · 4 Litres (diluted up to 5:1) – treats up to 100m² · For heavy application: dilute 1:2 with water to treat up to 60m² · For light application: dilute 1:3 with water to treat up to 80m² Application Instructions 1. Choose a dry day with no rain forecast for at least 48 hours. 2. Fill a 3–7 litre pump-up garden sprayer with 2 litres of clean water, then add 1 litre of Grean Boss (to avoid bubbling, always add the product after the water). 3. Apply generously to an area no larger than 15m² at a time, ensuring the green stains are completely saturated. 4. Repeat the process for larger areas. 5. Leave the treatment to work over the next 3-5 days — green stains will gradually break down and disappear as natural weathering takes effect. 6. For shaded or north-facing areas where green stains may return, simply re-treat locally as needed. Safe, biodegradable, and acid-free, Grean Boss is tough on green stains but gentle on your stone, roof tiles, and surrounding garden.
