SmartSeal Green Clear Pro - 5 Litres - Biocide (Health & Safety Executive Approval Number 11004) Powerful Green Algae Remover - Best Lichen & Black Mould Remover - Perfect Roof & Driveway Cleaner

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

Have used it twice on small areas of moss covered paving and it seems to work. Moss was reasonably easy to scrape off after leaving for 4Days.

Good product - excellent customer support

After two coats, black spots remained. Product too weak.

Great stuff really helps when cleaning roof, superb

Kills the moss quite quickly but requires a second application a few weeks later. I now use vinegar bought in 5L containers. Also needs 2 applications at a fraction of the price,

Brilliant product, actually works! No hesitation in using again

The poor weather hasn't helped regarding the application on my driveways. However the small window of opportunity allowed me to apply the moss killer and after a few days it has changed colour. A little too early to say if it is long lasting and permanent. Will order again though.
