A couple of months ago I had a new patio laid of smooth Indian Sandstone. I've recently noticed 'mottled' staining around the perimeter of some of the flags. In some cases, the staining covers the centre of the flags also. I am quite concerned that what I am seeing is 'reflective' staining. The patio flags were laid on a full mortar bed - but the slurry primer wasn't extended to the edge of the flags - I was told this was to reduce risk of staining the upper side of the flags. I have some photos - but not sure how to attach these to the post. Any thoughts?
