…..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’…..😊

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.

Unsure why others have found this solution to be less than 100% effective. I used it as 1 to 5 in water as recommended and it is economical to use with a lance sprayer and works within 24hrs - well the moss have turned yellow and looking very unhappy! Unsure how long this last but follow the instructions and from my experience the moss is hit hard and dead post application.

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.

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.

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!!

Having tried a variety of moss killers, I have finally found one that works for more than a month. Not sure that it will kill moss for a year, as it claims, but as this is the second lot that I have bought, I know that it works for over six months. Point to note, this does not eradicate moss, it only kills it. You still have to scrape or brush it away when it has died.

During the summer I planned a long awaited DIY project to remove moss off a cedar shingle roof. I thought it was going to take 3 weeks but eventually took 10 weeks and a day minus 4 days of rain and minus the two afternoons of the hottest days on UK climate records. Initially I was taken in by sales blurb that moss killer was going to be magic. No it wasn’t. Eventually the following process was arrived at but prior to that have to have multiple tool & broom heads attached to 7m :- Brush the roof with broom with rubber bristles. (this wasn’t the stiffest bristles brush head I found but sufficient to dislodge much of the moss. Scrape and scratch the stubborn patches especially the gaps BETWEEN the shingles. Found it was impractical to use scrapper any wider than 6cm and the scratcher had to be about 2-3mm. This was because wooden shingles are not like tiles, they are not totally flat in the first place such that weathering make then curl up to U shape and shrink over time leaving gaps for moss to hide in. Spray Moss-Go Moss Killer, section by section. Each section to wait a day to dry. Come back to section to scrub with very, very, stiff bristle, e.g. Draper 17190 or if that doesn’t work a Draper 17189 steel wire brush. Ensure all moss and dust brushed off after scrubbing. Spray Everbuild Triple Action Wood Treatment. Wait a day to dry. Spray Roxil Wood Protection Liquid. Roxil recommends two coats but with the project exceeded so many weeks late, I didn’t have time to go around the house again to spray. The design of the house, garage, awning has large roof area and to reach them all requires about 12 to 14 moves to relocate the scaffold tower so each spray coating (of any of the 3 chemicals) required best part of a week, depended on rain and winds. Conclusion = Moss Killer alone not enough, a lot of elbow grease was a pre & post requisite. After application and scrub processes, there was a big difference to how the roof looked but didn’t totally look clean until after the application of wood treatment stage. However, to skip out the moss killer stage could have been possible but Moss-Go cost a fraction of subsequent treatments. I used it at strongest recommendations mixture of 1 part Moss-Go + 5 parts water. (Subsequent treatments had to be used neat, no mixing with water = expensive but did kill off remaining moss remnants and …. still need final scrub & scratch for the very stubborn moss hiding in gaps and corners).
