SmartSeal Roof Cleaner Xtreme - 2 x 5 Litre

Mine needed two sprays

This is amazing. Scraped off the moss and lichen with a wire brush . Sprayed onto our tiles about 3 hours later I washed it off. They look like new !!!

Not had chance to apply yet but quietly confident. At a max 1:1 dilution it is expensive, with some quoting 25:1. High expectations.

Did a great job on a North facing roof. Delighted with the results.

Doesn’t go far with a 1 to dilution rate so therefore works out expensive and not that effective 7 out of 10 at best. Only suitable for outdoor use due to strong fumes, won’t buy again for a large area

I would reccomend this for moss and dirty roof tiles. Just spray and let it work. Next thing you will see new looking roof tiles.

Kills the moss straight away on contact. Left for a few days before I cleaned off without too much effort.

The product did the job well, if a bit expensive. Got to say the ‘buy two and the second one is half price’ that was advertised did not work. I got charged for two full price packs even after messaging the seller beforehand (and no reply). Good product though. Also used on two low walls with good results. Remember to wear protective gear too.
