I've just got my garden done up with white Indian sandstone. It all looked fabulous for the first few days until the tiles started appearing wet, even though it hadn't rained for a good few days. Now the patio looks patchy and has wet spots, which refuse to dry off. Is there any specific reason for this and can I mend this at all? The guy who did the job is very sorry about the fact that he didn't use a sealant whilst laying the patio - does this mean that the whole job needs to be redone and the tiles are going to be wet all through out?
This is very concerning as getting this done wasn't cheap.
