Black limestone problem after sealing new patio
Posted: Sun Jul 05, 2015 8:13 pm
Hi. I have had my patio laid and i was to clean it and seal it, after two coats of wickes patio and block paving sealant it has started to look grubby and dusty but after spraying it downs with water it looks clean and refreshed, have I sealed it wrong? It was done on a dry sunny day. Also there is a lot of what Iv been told salt coming out of the black pointing, is this something that will pass with cleaning. The patio has been down for 4 weeks thanks
