Patio Guard Patio cleaner, block paving cleaner, driveway cleaner, decking cleaner, Trade Strength-5L

After having the front of the house tarmacked several years ago I was aware that moss was one of the causes of the surface breaking up. I tried other products but this has been the most effective treatment. Using a commercial-grade hand pump sprayer this is easy to apply and safe for pets to walk over once dry. Using it as directed on dry days allows you to see where you have sprayed and get good coverage. After the moss is dead, and after several weeks I just jet wash the loose dead material away, leaving the surface clear for a year. A very effective product.

Bought this to spray house roof after cleaning, diluted 7ltrs water to 1 ltr liquid the entire roof given a good one coat soaking, as instructed this done on a dull day without rainfall forecast within five hours of spraying, in actual fact no rain forecast for days so just dried naturally. Now some two months later the roof still clear of Moss but the Lichen still showing as white marks on the roof tiles, my neighbour said his had disappeared after using an alternative product so not to sure if this product has disposed of the Lichen or not. Easy to use product, no moss reappeared but Lichen regrowth unknown.

As you can see from the before and after pics this product removed the green algae from our white exterior wall quickly and affectively. Takes a few hours / overnight for the full effect to take place. Good value for money. I diluted it 250ml in a total volume of 1250ml which is slightly more concentrated than recommended because I found it worked best at this strength. I was using it on the front of the house in preparation for painting but it did such a good job I don’t need to paint now so it has also saved me money. Very pleased!

Good points - arrived on time and well packaged. Did work, but took a few days to really take effect. (Applied on a warm sunny day and the following days were just as good) It has been over 3 weeks since I used the Moss Killer and there are no signs of it coming back. Recommendations - following the instructions, I used a watering can and I honestly wasted so much solution, that i had to then purchase a second container of the moss killer, so please use a pump spray (bought a 5ltr pump cheap from amazon) The spray went directly on the moss, rather than absolutely everywhere and I used so much less! Not so good points- It did kill the moss over a few days, however it really did not remove much of the algae from the slabs. This was an expensive lesson.

Firstly this stuff kills moss, I've seen some reviews saying that it doesn't work. It does work I've used it on my roof and it killed the moss. What it doesn't do is remove moss that is still down to you and a brush but it's 90% easy to remove than not using it. I done it both ways and with is way better. Make sure you have a good few days of sun and no rain coming and leave it for 4 or 5 days after you've sprayed it. Brilliant!

Having been watching the dastardly moss growing on my roof for a couple of years and received a quote for 500 to remove I hatched a cunning plan. I couldn't find any reference to using this in a snowfoam pressure washer adapter but gave it a whirl. What could go wrong. Heath Robinson would be proud. The final setup consisted of me at top of ladder and the k2 perched atop a 2nd ladder next to me to allow sufficient height to peep over the roof line and squirt a thick wadd of said chemical over the roof. This stuff chuffs up better than my actual snow foam and soon the problematic roof was covered in a thick layer of you know what. Unfortunately the Mrs who had been asked nicely to stop the k2 falling of the top of my 2nd ladders was also smeared and now possessed with a face like thunder as she had just had her hair done. Still I was basking in a sense of glory at how well this plan had come together and this far outweighed any worry about getting this in the wife's eyes or the mini ecological disaster I had likely set in motion. No idea of the final concentration achieved but a full container of solution was put through the snow foam lance I can't wait to see what happens in a few days!!

…..but be prepared for a bit, no, wrong word there, PLENTY of elbow grease! It was finally sprayed on to pavers on 8th December last year by my gardener. The frost that day was still on the ground at 4.30pm - I really didn’t think it would work. But, after a few months, lo and behold, the moss was def dying off. It could have been removed with the back of the broom but such a vast space to do, nobody here was up to the job….bad backs being the reason. It has since resurfaced greener than ever! Just ordering another for gardener to put down and hopefully talking him into getting his back sorted well before the dying off period! I can honestly recommend this product but be prepared to shift it when it dies, it won’t just disappear from view….you’ll need to put your back into it for that. Bought again September last year but sadly, this time around just did not work. In fact it seemed to flourish rather than die. Recently gardener put down salt and sprayed with chlorine…..a few weeks later still waiting for the ‘brown look’…if anything at all is happening, it is very very slow. Will most probably have to get it jetted but large area to do. March/April 6/7 months later, moss is finally dying off but will need somebody with a good strong back to ‘finish off’…..😊

Would not buy it again 10l I'm still have patios full of moss year before i buy deferent make 5l moss gone for all year round not happy at all.
