Larger tile, thinner tile from 3-5mm, plank tile, and the end user who wants grout joints 1/8” or less—they all beg the question. How much more difficult can they make it for tile setters? Our company has had to purchase larger tile saws just to accommodate the ever-increasing “large-format tiles.”
So what’s happening with all these larger format tiles? More lippage. Now, you might think if the substrate is flat you shouldn’t have to worry about lippage, right? Not exactly. What we’re also faced with is the tile/stone itself is not perfectly flat. So combine this with the larger tile sizes and small grout joints, and you end up with lippage.
