lichen on block paving on driveway

United Kingdom Gb

how do i remove white coloured lichen on a block paved drive please tried algon to no avail.



Is the 'lichen' actually within the block paviours rather than sitting on top of them? When you used the Algon, did it have any effect at all, even temporarily?

you could try a fungicide as a lichen is an organism that is made up of a fungus and alga living in harmony.

An application of a strong bleach solution. Work it in with a stiff brush, leave it for about an hour, give it a good scrub again and hose it down. Failing that use a pressure washer.

if theres know plants salt works well or as Myron sais bleech but I would scrub it in and leave nature to clean it . don't use jays fluid as it actually promotes alga once its washed off .

Hi thanks for all replys... the lichen is mainly laid on top of the bricks with a few between the joints, cannot use bleach as near to lots of plants. We have tried algon twice using 3 to 1 solution put it as only removed it a tiny bit.Thanks

Why do you want to remove it? Lichens are beautiful and people try all kinds of tricks to get it to grow to give that established appearance.

We were advised not to use a pressure washer on our block paving - anybody got any experience of this?

Hi did you mean neat salt....... or to put salt in water.thanks for help.

I wouldn't recommend the use of salt at all - the salt can mark or stain the block paving indelibly. Check with the manufacturer of the paving to find out what you can and can't use without damaging it.
