The last 7 years I've been working on a tile exterior deck saying the same thing to my boss .... Start over stop the cancer a 1 mill house that never ends at first I thought it was the owner then today I find its poor construction like I said fix this mess right !!! Tomorrow is the last straw I'm going to demo the deck!!! 5 k in Italian tile and 4 inches of mortar fook me with the saving of the tile!! But I have too.
