Where's the orange rubber Ditra underlay for her tiles to float on as the building expands and contracts and shifts?? Her fucking tiles are gonna crack. What a dumb propaganda shot. These people are so fucking stupid.

What is Ditra you ask?

>>Schluter-DITRA is a polyethylene uncoupling membrane used under tile to provide uncoupling, waterproofing, load distribution, and vapor management, preventing cracked tile and grout by separating the tile from substrate movement. It is a thin, lightweight, and quick-to-install alternative to cement board or plywood underlayments for ceramic and stone tile installations over various subfloors.

The ancient Romans did this with a sand layer so that the marble floor surface would float above the brick or concrete flooring.
