Slate tile outdoors
Been asked to repair a black/grey slate, under a covered patio. The slate has a layer of "clay" on the surface, very easy to scrape off with a fingernail. I suspect it was never sealed. It makes "mud" when wet. Is it possible the acid wash maybe, and clean then seal? or is there a better option. The patio is upstairs, on regular deck framing, with a belly in the middle. But thats for another time.
