Do i need ditra on concrete floor.

The ditra will cost approx. Over concrete or gypsum use unmodified thinset mortar. I think the benefit far outweighs the cost. About to tile a concrete floor in the basement of a home.

Plan to use ditra mat which i ve laid several times before. Yet this application does make sense since concrete is heavy solid and is typically thought of as an unbending uncompromising material. Using ditra normal cracking which occurs in concrete slabs will not adversely affect your tiled floor. The floor is a 4 poured concrete slab on grade with moisture barrier and 2 sm insulation under the concrete.

For installing tiles on ditra. Or is priming of the concrete substrate unnecessary. If i find myself needing to tile over anything other than new level concrete i ll probably go with ditra again. Don bell denver co.

Use our ditra heat calculator to find out what products you need to complete your specific installation. We also have an in floor glycol heating system. I can see maybe some value as the floor has a join of 2 different materials. Adding ditra to a tile flooring job will cost about 2 per square foot.

The timber floor is being newly laid so should be solid we are then self levelling the concrete to fill gaps and bring up to timber level layout wet underfloor overlay boards and finally tiling using flexible adhesive. 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. My only question is do i need to necessarily prime the concrete before then using thinset into which to embed the ditra mat. 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. We have just been told that we will need to lay ditra matic under the tiles. Given concrete is pretty solid and the additional cost for laying ditra matic is substantial is it really necessary. 3 000 and i am not sure if we really need it on a concrete slab.
