Has anyone got a good solution for killing moss on a tarmac drive? A big chunk of the drive is very shady (trees have TPOs so we can't do much) and moss grows like mad. I've tried a couple of commercial products, a burner, bleach and salt and nothing seems to kill it off. Any ideas?

Yes "Wet and Forget" will get rid of it it needs two days dry to work then you will see it going brown when dead power wash off then next year it needs another coat to keep clean.

Ha! When did you last have two dry days ?
White vinegar, you can use malt but that does smell and it is cheap in Aldi .

HTH or pool acid.
Ah, I did try that as well with little success. Think I must have a mutant moss!

Don't hold your hopes up. I've got half a container of Wet and Forget, that you're welcome to, as our moss just sniggered at it and treated it as fertiliser.
Pool acid is Hydrochloric or Sulphuric acid and are used to bring the PH of a pool down to an acceptable 7.4 PH, but both will react with the silicon content of paving, good idea for cement stains, but not for moss IMO.

Ha Ha you missed the 2 dry days out.
I use my pressure washer to blast the moss off my driveway.I'll wait for the weather to improve maybe?
Tried that, took ages and it was back in a couple of weeks.

What am I doing here?
Look out for product containing DDAC, although not listed as mosskiller it does kill moss as well as algae and lichen. I use it twice a year at work on tarmac and hard paving. You might have to sweep off the dead moss the first time if it's bad, but from then on it'll just weather away
Sapphire is a good one if you can get it

Best used only on asphalt or concrete. Tarmac doesn't like pressure washers.

Neither does the grouting between the large tiles. DAMHIKT

The most wasted of days is one without woodwork
Had same problem on a porch roof.
Scraped worse off, used Black and Decker Spray and leave. Not had any sign of growth, and it's been about 8 months.
Only tip, is look to buy the concentrate, dilute as instruction and use a pump spray weed type sprayer to spray it.
The pre diluted one that you see in the likes of the range, home bargain etc for about £4, which ive tried before, never did a decent job.
I was given a concentrate one to try and it worked a treat.
