Just the job.
Used it on my tarmac drive. 12 months ago. No sign of any moss returning. Good value.

Works... eventually
I applied this to a very mossy garage roof last September, having bought it a few weeks before. I followed the instructions and waited until the temperature was below (i think I recall correctly, but read the instructions yourself) 20 degrees celsius. We bought the house 3 years ago and I suspect there was 20+ years of moss and lichen on the garage roof. It is now the following April and until about three weeks ago, I thought that the product had been useless: no loss of moss/lichen and the roof looked just as awful. However, my ex-farmer friend visited and when I told him SmartSeal had not worked, he said "yes it has!". He pointed out that it was dry and dead, but still affixed to the roof. All it needed was a scrape with a stiff brush, or, I'm hoping, the drying effects of the sun plus some wind might remove it entirely (it has been an exceptionally wet winter in the UK).
