Restore the beauty of your driveways, patios, and garden paths with our powerful patio black spot removal for block paving.
Specially formulated for block and brick paving, this advanced cleaner is designed to tackle the stubborn black lichen spots, white fungi, and green algae that build up over time and are almost impossible to remove with water or pressure washing alone.
Available in two convenient sizes:
2 Litres – treats up to 10m²
4 Litres – treats up to 20m²
Unlike general-purpose patio cleaners, our solution is developed specifically for patio black spot removal for block paving, penetrating deep into the surface to lift dirt and biological growth from within.
This not only revives the original colour and texture of your paving but also makes rinsing easier and safer, without the damage often caused by aggressive jet washing. By reducing reliance on pressure, it helps protect the sand and structure of your block paving, ensuring a longer-lasting finish.
For year-round protection, we recommend following up with our Patio Black Spot Preventer. Applied annually, it removes algae within 3-5 days, stops spores from germinating and prevents black spots returning, keeping your paving clean and fresh, helping reduce power washing.
Safe for your garden, the formula is biodegradable and acid-free, so it can be rinsed onto lawns and flower beds without harming plants or soil.
Patio Black Spot Remover is safe is safe to use around pets. As a precaution, we recommend keeping pets off the area whilst applying the product. Once the Remover has been washed off the surface, it’s instantly safe for pets to walk on the area.
Coverage Guidance: The stated coverage is based on paving around three years old. Older or heavily marked areas may require repeat applications. Always test on a small, inconspicuous area first to determine how much product you’ll need for your paving.
1. Use neat – DO NOT DILUTE – Pour our solution into a pneumatic garden sprayer. (A ‘Hozelock’ 5L or 7L sprayer is recommended. Do not use a hand sprayer.) Pressurise the sprayer.
2. Apply the product to a dry surface, as a fine mist and saturate the surface.
3. If you have not used the product before. Treat just one slab first. The older the stone, the more treatments it will require. The product will remove every single last spot. By completing one slab first, this will give you an indication of how many treatments your stone will require. Only when you have removed all the black spots from the first slab, continue with the rest of the area.
4. DO NOT EXCEED THE MAXIMUM RECOMMENDED COVERAGE OF 5 SQM PER EACH 1L OF PRODUCT.
5. Once applied, allow to cure for a period of 2 hours.
6. Remove using a pressure washer, ideally with a minimum flow of 7 litres per minute. Use the fan jet attachment to sweep the dirt away. Other attachments such as circular spinning attachments will not give you the best results.
7. Any black spots that remain, simply retreat (when the surface is dry) allow to cure for 1 hour then wash off.
8. Repeat this process until no black spots remain.
9. Apply the Patio Black Spot Preventer 12 months later. Do not seal the patio.
Exceeding the recommended coverage rate will reduce the performance of this product. Coverage will vary depending on surface porosity and profile, e.g when treating sloping areas or riven surface, beware of surface run off and retreat as necessary to ensure correct coverage.
The Patio Black Spot Remover is quickly and readily biodegradable. The effluent if washed into soil, flower beds or lawn will breakdown rapidly. This product will not affect surrounding lawns or foliage in diluted state. Keep animals and unprotected persons off the treated area until dry.
Ensure product doesn’t come into contact with skin, eyes or respiratory tract. In the event product does comes into direct contact with the body, immediately rinse with water. Ensure this product does not come into contact with fabrics or furnishings.
