Garden Xpert Algae, Lichen & Mould Concentrate Cleaner | 5 litre | Suitable for Patios, Roofs, Paving Slabs, Paths | Lasting Protection | Huge 250m2 Coverage | Pet Friendly Once Dry

I removed the bulk of moss from my roof with a scraper and brush. I then prayed my roof to remove the remaining bits of moss and prevent regrowth. The roof is made up of Marley tiles approx’ 60 years old. The Garden Xpert Moss & Algae Concentrate Remover is supposed to cover up to 250sq mtrs. I managed to cover 55sq mtrs. I think all the suppliers overestimate the coverage, and the key words are 'up to'. So, prepare to purchase two packs.I will report back if the product works as, it should. Other than this, it actually says it will kill moss. Others costing the same or more only tackle algae and mould.

Cannot believe how good this stuff is !! Sprayed it on various walls with what I thought was ingrained algie - at first disappointed it wasn’t working - I didn't need to worry - This morning virtually all gone - never had anything so good

Early days but it appears to be working so far

I tried to contact the manufacturer of this fluid to check it was OK to use on uPVC. I never got an answer, but I use it anyway. My conservatory gets pretty green through winter and this helps loosen that. I use it pretty dilute just in case there's an issue, but it doesn't appear to do any damage and helps lift algae in hard to reach places.

Good value and easy to spply

It did the job effectively.

Easy to apply - but still no positive results on drive after 10+days

Kills miss fast. It doesn’t prevent for more than about 6 weeks so you will have to apply about that much in winter for a north facing courtyard
