Got mentioned to me awhile ago moll, they come out and use an acid to burn the top surface of the brickwork off on your your drive for instance, a block paved drive then they coat it in a clear laquer, reason the bloke mentioned it to me, was his neighbours had it done and he said it was well smart, but when they went to park their car on it slid of into the lawn and they had to get him to pull them out the mud.... :11:
