    are you sure it's not the salts that sometimes come out of bricks? Have a look at efflorescence
  • I am sure, its definitely not that, its the same that also grows on walls, etc. Have taken a wire brush to it and that takes it off but would take me from now until 2022 to do it all as theres so much!!

    Could you post a photo on here?  That would help us identify the problem, perhaps.

    Is it a lichen of some kind?
    A great library has something in it to offend everybody.

    Without a photo it’s hard to be certain, but have a look at lichens and liverworts

    Looking at the photo's I'd say lichen - you have at least two kinds, one of which is white. If so, best learn to love them as removal is more effort than it is worth and only temporary.  Some info. here:
    A trowel in the hand is worth a thousand lost under a bush.
  • Thanks BobTheGardener, that website was helpful, just a shame they are not easy to get rid of as the driveway is starting to look unsightly

    Yes lichen ... and the good news is that it’s indicative of good air quality
