Do i need ditra on concrete floor.

Installing tile directly on concrete. About to tile a concrete floor in the basement of a home. My only question is do i need to necessarily prime the concrete before then using thinset into which to embed the ditra mat. Should i lay ditra on the wfh overlay boards.

The floor is a 4 poured concrete slab on grade with moisture barrier and 2 sm insulation under the concrete. With ditra heat your floors can combine the beauty of tile with the proven crack free technology of uncoupling and the comfort of an electric floor warming system. Or is priming of the concrete substrate unnecessary. We are in the middle of a refurb and have a concrete kitchen floor with under floor heating which we are planning to lay porcelain tiles onto.

I don t insist on ditra or any other uncoupling membrane when tiling over concrete floors but i do recommend it. Ceramic and porcelain tile are so frequently installed at or above grade level on a cement board underlayment or directly on plywood that it almost seems novel to install tile directly on concrete. I think the benefit far outweighs the cost. We have just been told that we will need to lay ditra matic under the tiles.

Adding ditra to a tile flooring job will cost about 2 per square foot. Over concrete or gypsum use unmodified thinset mortar. Given concrete is pretty solid and the additional cost for laying ditra matic is substantial is it really necessary. If i find myself needing to tile over anything other than new level concrete i ll probably go with ditra again.

Yet this application does make sense since concrete is heavy solid and is typically thought of as an unbending uncompromising material. 3 000 and i am not sure if we really need it on a concrete slab. I can see maybe some value as the floor has a join of 2 different materials. Plan to use ditra mat which i ve laid several times before.

The ditra will cost approx. Using ditra normal cracking which occurs in concrete slabs will not adversely affect your tiled floor. For installing tiles on ditra. We also have an in floor glycol heating system.
