I need to secure a range hood on my new subway tile backsplash. Behind the tile is the thinset, drywall, then concrete block. I don't think my furring strips are ideally located for mounting purposes.
My plan is to use 1/4" Tapcons which require a 3/16" pilot hole. That's fine, but should I first drill the full 1/4" through the tile, thinset, and drywall until I reach the block? My concern is that driving the Tapcons through the tile and thinset at 3/16" could potentially crack the tile or affect the integrity of the thinset.
