Hi, I wonder if anyone can help. In February I had 30msq of black limestone laid at the front of my house. Since then the chap who laid it has tried to sort out the dreadful staining that appears. He has used Colour Enhancer and then Stain Stop but I've just hosed the area down again and now that its dry there are still patchy water markings all over it. It looks awful. I'm sure I read that these slabs should have been sealed before laying is this correct? I wonder if anyone near to me in Dulwich could have a look at it.
