Patio Magic!16491 Concentrate: Ideal for Patios, Paths and Driveways (Kills Algae and Lichens), 2.5 Litres

This is such. Great product- it really works so I now have no need to pressure wash my patio nor the concrete paving path the front of my house. It’s absolutely solved the black spot problem on the sandstone ! Although I’d recommend if you have black spot growth on your patio to at least double the strength of the mixture or even use a stronger mix. I’ve used Patio Magic for over 5 years now and it’s saved so much time and effort. It doesn’t work immediately but after 6 -8 weeks you will really notice the difference. Recommend.

So so with the product. Appears to perform better with a stronger dilution. Could be down to my paving. I sprayed with product then after an hours I power washed. Paving came up like new, but I wouldn't say it was any better than previous years with just a power wash. Will be able to judge over winter months to see if prevents the build up of dirt and algae.

Excellent results. Took only a day for a noticeable transformation and on the second day it looked like a miracle! A patio that never looked so new and clean that previously was covered in green algae and moss. It was so easy to use and required no effort. Very quick results. You dilute it in water as instructed in a watering can with a shower head attachment, walk around pouring it onto the patio after moving any objects out of the way first and for 5 litres is enough for a small patio but for bigger areas you would need more than 5 litres. Just leave and walk away. Make sure you check weather forecast first as best done when no rain for a few days. Keep pets indoors when you apply this. Don't allow pets or wildlife to walk on this product until it has completely dried up. Read instructions.

Excellent product. Have tried others before, but this has been the best. Managed to do our front and rear patio with no trouble. After a couple of days the mould started to go and since it has rained it is even better. The jet washing will be quicker and easier his year. Would highly recommend this product. Great value too.

Used as directed... It says it cleans over weeks / months, it's been a month now and I can't see a lot of difference. Path only 2 years old. Perhaps I'm not as patient as I thought!

I know use this annually instead of getting my Karcher out. Simple to use, sprinkle on and watch the patio get cleaner over the next couple of weeks. Fabulous 👌

Works very well.

This stuff is amazing. It takes a few weeks before the effects are really noticeable. The area stays clean for a long time afterwards. I gave my flagged area acouple of sprays, which was pretty effective. It also got the black marks off, as well as the green algae. Saves messing about with a pressure washer.
