Patio Black Spot Preventer

Keep Your Patio Looking Better for Longer

Once you have restored your paving with Patio Black Spot Remover, regular maintenance is essential to help prevent black spots from returning. Our Patio Black Spot Preventer is specially formulated to provide long-lasting protection, helping to keep your stonework cleaner and looking its best throughout the year.

Patio Black Spot Preventer is specially formulated to help protect your stonework from black spots and organic staining, providing long-lasting protection without the need for constant cleaning or pressure washing. Applied annually, it helps maintain the natural appearance of your paving and keeps your outdoor surfaces looking their best for longer.

Why Does Black Spot Grow on My Patio?

Black spot is a form of organic growth that develops on outdoor stone surfaces over time. Moisture, shade and organic debris can create favourable conditions for black spot lichen and other organic growth to establish.

Black lichen grows on trees and lands on your paving. If left untreated, it begins a two-year germination period where it starts feeding off the minerals within the stone. You typically see black spots appearing on stonework after three years of being laid. Once established, black spots can become difficult to remove with ordinary patio cleaners or pressure washing alone.

This is why prevention is an important part of patio maintenance.

When should I apply the Preventer?

It’s recommended to be applied 11-12 months after using the Patio Black Spot Remover. Using in spring each year is the best period to apply because it removes algae that grows over the winter period without the need to pressure wash.

How do I apply?

-Apply using a 5-7 litre pump-up sprayer
-Dilute the product 3/1 with water. 3 parts water, 1 part product.
-Spray all areas
-Leave to dry
-No need to wash off

Patio Black Spot Preventer is not a cleaner of dirt. It will prevent black spots from reappearing on your patio and remove algae within 3-5 days.

Should I Seal My Patio After Cleaning?

Patio Black Spot Preventer is designed to be used as part of your ongoing patio maintenance routine and does not require the patio to be sealed.

If you have used Patio Black Spot Remover, it's recommended to follow up the following year with the Patio Black Spot Preventer rather than sealing the patio.

If you are considering using a separate patio sealer, always check that it is suitable for your particular stone type and intended use, although we do not recommend the use of sealers as this will not prevent organic growth and staining.

Why Choose Patio Black Spot Preventer?

Patio Black Spot Preventer takes a proactive approach to patio maintenance. Rather than waiting for black staining to become established before treating it, the Preventer helps protect your paving against future organic growth.

When used annually, it helps:

• Prevent black spot from returning
• Target black lichen spores before they develop
• Clear green and red algae staining within 3–5 days
• Maintain the natural colour and appearance of your stonework
• Reduce the need for frequent cleaning and pressure washing

Help keep slippery organic build-up under control
