How to choose
Picking the right treatment
Measure the area first
Coverage per litre is listed on every product page. Work out your square metres, then check how far a bottle goes once diluted.
Concentrate or ready-to-use?
Concentrate works out cheaper for patios, drives and large areas. Ready-to-use suits furniture, glass and smaller jobs where you want to spray straight from the bottle.
Match it to the surface
Most treatments cover paving, decking, render and roofs. Artificial grass has its own dedicated cleaner - check the label before you start.
Outdoor cleaning questions
Do I need a pressure washer?
No. These are spray-on treatments that work over time rather than blasting the surface. Apply, leave it, and let the weather wash the dead growth away.
How long does it take to work?
It varies by product, surface and weather. Contact times are printed on each label - check it before you start so you know what to expect.
How much will I need?
Coverage per litre is listed on each product page. Work out the square metres you are treating and check the dilution rate on the label, as it varies by surface.
Is it safe around pets and plants?
Follow the label. Keep pets and children off treated areas until dry, cover nearby planting, and observe any re-entry times stated on the product. Use biocides safely - always read the label and product information before use.
When is the best time to treat?
Late summer through autumn is ideal, before damp weather lets moss and algae take hold. Treating a dry surface on a still day gives the most even coverage.
Can I use it on artificial grass?
Use the dedicated artificial grass cleaner rather than a general patio treatment. It is formulated for synthetic lawns and play surfaces.
