Applied annually, it will prevent staining and discolouration and remove green algae within days without the need for power washing. The Preventer should be applied 12 months after the initial removal process.

Coverage Tip: The coverage rate is based on a patio around 3 years old. Older or heavily stained stone may require additional treatments. Always test on a trial slab first to gauge results for your surface.
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.
