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

It arrived on time, great price and works really well.

Applied with a pump action sprayer, easy job, brilliant results on timber, cleared years of green mould growth just like that. However no effect whatsoever on mould/lichens on paving flagstones. If you do spray, pick a calm day and wear a mask and glasses/goggles, this stuff is so super fine it hangs in the air and floats all around.

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.

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

longterm use may work on larger patios

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

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

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.
