Tarmac Driveway full of moss/weeds - hot to fix?

Absolutely do not power wash tarmac. You will destroy the surface, dig up a lot of chippings and the moss and weds will be worse than ever.

A1, here's a question for you, have more growing in garden along by the kerbs. What to use that's ok for lawn and kerb/tar? Any idea?

If it's weeds in the tarmac along the kerbs I'd use Roundup very carefully on a very still day with the spray head held very close to the ground and maybe a sheet of ply or a plank held upright along the kerb to shield the grass.

Glad it rained before I could get going with the power washer on Saturday

Sorry, moss (damn spell check) growing in the lawn right by the kerb, any idea?

As already said , washing powder or jeyes fluid

stoneill · 30-01-2020 8:52am

Weed burning blow torch for the big weeds, then a bleach or jeyes fluid solution brushed on to kill moss.
Power washing will disintegrate a tarmac driveway.

I use Formil non-bio washing powder from Lidl, diluted with warm water and put it a weed sprayer. Give all the moss a good soak, within a few days it will all turn brown, you can then brush it off with a stiff yard brush, works very well on weeds also.

This literally works on everything, we use it on brickwork, cobble lock paving, wood etc..

Old thread I know, but can anyone tell me what concentration to dilute the washing powder at?
I've read before that it's 1 cup to 10 litres but that seems very weak?

Baoithin66 · 24-09-2020 8:20pm

I just bought the cheapest power in Lidl and shook it out by hand over the moss (like spreading lawn seed)

we have something similar to this and it is really good at moving moss etc from tarmac, can be a lot of debris to clean up after but instant result.

Is that €1600??? You'd but a lot of washing powder for that

Commercial machine, much better than caustic soda and potassium hydroxide (KOH) or caustic potash. These are the most commonly used alkalies in soaps and detergents.

A hoe and a yard brush.

Strimmer with plastic gut.

Varik · 24-09-2020 10:43pm

I bought a cheap metal brush head for my strimmers.

Have one of these as well but the vibration plays havoc with the body.

TheRiverman · 24-09-2020 11:02pm

I use Daz detergent powder for moss on tarmac, just put it in a bucket and shake it on.It will burn it into oblivion.

Fireside Solicitor · 17-10-2020 7:52pm

Bio washing powder and plenty of it.
No power washing will lift the stones if the bitumen is old.
A good hard brushing once the moss dies.
You will need to do this 2 or 3 times between September and April.
Hope it helps

salamiii · 17-10-2020 9:42pm

spray with vinegar

dinneenp · 22-10-2020 11:48am

Hi.
So sprinkle bio washing powder on or dilute it? Which is best?
Thanks,
Pa.

youtheman · 22-10-2020 12:03pm

I normally sprinkle the power when the ground is damp or when some light rain is due. No point in putting it down if monsoon rain is due.

Fireside Solicitor · 22-10-2020 12:19pm

When rain is due put it on

Fireside Solicitor · 22-10-2020 12:20pm

When rain is due put it on. Although I put it down once and didn’t rain for a few days and still did the job

Accepting the moss is not doing you any harm would be the cheapest option.

I find if left untreated it gets onto the car. Washing powder is best.

Fireside Solicitor · 22-10-2020 12:22pm

True. And if it’s windy you get covered in it but at least your clean

Limpy · 22-10-2020 12:23pm

Feck if it was the council's tarmac you could slip,.claim and you'd get money. With an added bonus of them cleaning it pronto.

G1032 · 27-10-2020 9:23am

I spread some Daz on the drive on Friday last
How long does it take to kill the moss?

banoffe2 · 04-04-2021 3:15am

we have a very large gravel area to get rid of moss, was wondering could we use the liquid Formil in the knapsack and spray it on, as we have gone through 4 boxes of washing powder and only a small fraction of the total area covered, I also see somewhere that adding some bleach to the mix helps

A few bags of milling salt will do the job well.
A 25kg bag is ~ 5 euro in a hardware store.
Its much cheaper than washing powder and does the same job.
