I have a Pacific Energy Super 27 wood burning stove (2010 model). I'd like to put down a black porcelain hex tile (this product: https://www.homedepot.ca/product/an...ch-x-8-inch-hexagon-porcelain-tile/1001387710) as the hearth. I have a new build (concrete slab), and wondering if I can use ditra underlayment (this: https://www.homedepot.ca/product/sc...uncoupling-membrane-54-sq-ft-roll-/1000408405) under the tile and nothing else? It's 2 month old concrete so I want to use the underlayment to let the concrete dry through air circulation and to prevent tile from cracking.
