It had been over 3 years from I last cleared it of the green algae, it had a very thick covering and had turned black in places. I know it says to add 4 litres of clean water to 1 litre of it. I tried this concentration and then tried 2 litres plus 3 litres of water, both these weren't strong enough to cut through the algae growth. I ended up using a 50/50 concentration and 1 x 5 litre container was enough to cover the backyard. After 24hrs you could see a big difference and after 48hrs the backyard was completely cleared and cleaned of the 3+ years of the algae growth. That was just over 2 months ago and the yard is still clear of algae with no signs of growth back yet.

Will it take the grey colour from the tiles?** A: we used it on slabs which are grey and it didn't take any colour from them but I cant say about lichen on ur roof why not try a patch and u will see if it does anything but in all truthfulness I cant say as ours was a backcourt not a roof and it removed green mould on the slabs I hope this helps u **Q: Does it damage plants and artificial grass** A: I believe it does kill living grass. Have no idea about artificial grass. I have only used on concrete where it is extremely slow to act, be prepared to wait months! **Q: Can use on slate roof** A: I would say you can. I have used it on Solar Panels, tiled roof, driveways and garden furniture etc. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Definitely worth money Excellent Cleaning of Algae *by F***0 on 24 May 2026* My backyard is around 30m2 and fully concreted.

I sprayed my green covered wooden fence and when dry its back to original colour wood. Has stayed clear of the horrible moldy green for some time too. Noticed a slight improvement on my stone blocks but staining was quite severe because area is always in the shade and stays damp. Might need to use stronger concentration and more often in this area. ## Frequently Bought Together - Jarder 2 x 5 Litre Concentrate Spray & Leave Cleaner - Patio Fencing Decking - Green Mould & Algae Killer - Spear & Jackson 5LPAPS 5 Litre Pump Action Pressure Sprayer - Spear & Jackson 2LPAPS 2L Pump Action Pressure Sprayer, WHITE AND RED --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/49699994-2-x-5-litre-concentrate-spray-and-leave-cleaner-patio](https://www.desertcart.sg/products/49699994-2-x-5-litre-concentrate-spray-and-leave-cleaner-patio) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-29*
