Soluguard Multi Surface Biocide - 5L - High Strength, Ready for Use Against Fungi, Mould, and Algae on Internal and External Walls, Brick, Render, Stone, Driveway, Roof Tiles & Other Surfaces

Great product. Simple and easy to use, and really effective! Fair price as well.

This stuff is fantastic . I had loads of green stuff growing up my fence on my concrete gravel boards and my decking and patio... I sprayed on lightly at midday and by the next day it had all gone, was sprayed on a cold day in January. 100% recommend

I was seriously skeptical about a product like this, I didnt think it would remove algae very effectively, however it did an extremely good job for me and I would recommend this as a first step to a really clean patio.Be careful when laying it down, it does go slippy until it soaks in. So take care with your safety when spraying it, but it took about 2 hours or so to soak in my patio.I have also done my Inlaws with this also, this will be the true test to see if I got lucky, as their patio was a lot worse than mine.

longterm use may work on larger patios

Easily removed the green stains from fence , pvc, painted masonry and slabs - patio looks like I’ve painted everything

Delivery on time, good. The product does what it says. I have some closeboarded fencing and gates that face North and get quite a lot of green algae growing on them as a result. Poured the product into a 2l sprayer and gave it a goood covering. I only scrubbed the worst areas with a thick build up beforehand. 24 hours later - all gone and ready to re-paint with fence paint. It also worked on a bit of wall where there had been a leaking gutter.

I applied this with a sprayer on my k-rend walls in my garden. I used about 4lt to cover 60m2. The photos are from before, and 48hrs afterwards. It seemed to remove pretty much all the green stains but didn’t do much for the black ones. I’ve put some photos on to show the effects. I also tried it on some patio slabs, had the same effect. Seems to be a good product that does what it says.

Fantastic!! I now have a patio and garden path that looks like it just been laid. It also worked a treat on a sandstone Bhuda. Really easy to use JUST FOLLOW THE INSTRUCTIONS.
