Patio Black Spot Preventer

Keep your patios, paths, and decorative stonework looking their best all year round with our powerful Patio Black Spot Preventer. 

Specially developed to help maintain the spotless finish, this long-lasting treatment prevents staining and discolouration on patios and paths. Suitable for all stone types, it’s the ultimate black spot preventer for homeowners who want lasting protection without constant scrubbing or pressure washing.
 

Each 2.5 Litre container treats up to 50m² once diluted and is designed for use within 11–12 months of using Patio Black Spot Remover. When applied annually, it prevents black staining from returning, while also clearing away stains caused by green and red algae within 3–5 days of treatment. The result is cleaner, safer patios and pathways with minimal effort. 
 

Unlike standard cleaners, our Patio Black Spot Preventer works proactively to protect your surfaces from future damage, maintaining the natural colour and appearance of your stonework. It’s a safe, effective way to stop stubborn staining and keeps slippery areas under control.
 

Patio Black Spot Preventer is pet-friendly. We recommend you keep pets off the area whilst applying the product. Once dry, it’s instantly safe for pets to walk on the area.
