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

Firstly I do not write reviews, but this product was brilliant. It removed all the build up of algae and moss from inside and old bus shelter which I was renovating. Sprayed it and left for 72 hrs then give it a scrub with a coarse brush, finally used a small portable power washer to clean off.

Seems to work well

Purchased to clear algae & moss on outside wall prior to applying waterproofing cream. Had to spray walll twice - green dulled a bit but didn't disappear. Then scrubbed with wire brush. Sprayed wooden fence & and a very green gate with what I had left - almost instant results. So, excellent on wood/OK on stone

Does exactly what it says on the tin. A pity it is so expensive though.

Works well with great results on walls. Easy to use and gets to work fairly quickly. No strong smell and has good cleaning power

longterm use may work on larger patios

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.

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.

L'ho utilizzato sul muro di cinta con del muschio e dopo averlo lavato con idro pulitrice il risultato è stato molto buono. Bisognerà attendere nel tempo per vederne l'effetto della ricomparsa di tale efflorescenza.

Ho pulito tutte le pareti esterne sporche di verde per muffe e muschio. Sono passati due mesi dalla pulitura e non si sono ripresentate. Al momento sono molto soddisfatta del prodotto

Prodotto veramente efficace sia su muri interni che esterni. Applicato a pennello poi è imbattibile. Basta una passata e anche la muffa più ostinata sparisce. Soddisfatto.
