Does what it says if you mix right I mixed it up 4 to 1 and excellent results

I have a south facing patio (smooth sandstone) which in the first year of laying grew extremely slippery moss (like black ice when wet). This stuff wasn’t some kind of miracle remover, ended up doing that with my pressure washer, BUT over a year later and no moss regrowth on the patio or the fence or wall where I treated it following the pressure wash. Will buy more to treat again.

We have a patio made of Indian sandstone slabs which looked fantastic when first laid, but got really dirty and green in places quite quickly. Power washing sorts it out for a short while but the muck and green areas come back fairly quickly. We were thinking of having it all ripped up and spending a lot of money on porcelain paving.However I wanted to see if our patio could be saved first. We tried this stuff out and I honestly couldn't believe my eyes. In 3 days it had got rid of all the mucky looking and green areas on the patio. I was so pleased. However it's now 2 weeks later and somehow it's still getting cleaner and brighter. We are even more pleased. The lovely natural colours of the slabs are back. It looks nearly new again.I highly recommend this product. Much better than spending ages jet washing it and getting soaked and cold. Just follow the instructions, 10 mins later all done, you can't go wrong!

This product does not do as said tried it twice on the same part of my slates did no make any difference to the slates, still dirty so I'll now need to power wash it.

it works well easy to use

Good paint. Arrived promptly. Goes on easily and gives decent coverage

Not tried the product yet so unable to comment on whether it works. However, I’m very disappointed at how it is quite clearly not full to the top and makes me question if it really is 5ltrs. The image attached with my fingers shows where the liquid inside comes too.On this basis I will not be buying it again or would recommend it.

Not very good. Followed the instructions to the letter but although two applications at the recommended strength killed off the moss on my patio and drive they did not touch the green algae. Have had to resort to brushing it on at full strength with a soft broom to see if that works.
