Do I Need Ditra On Concrete Floor

Plan to use ditra mat which i ve laid several times before.

Do i need ditra on concrete floor.

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. 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. Using ditra normal cracking which occurs in concrete slabs will not adversely affect your tiled floor.

I don t insist on ditra or any other uncoupling membrane when tiling over concrete floors but i do recommend it. Given concrete is pretty solid and the additional cost for laying ditra matic is substantial is it really necessary. Over concrete or gypsum use unmodified thinset mortar. Use unmodified thinset mortar learn about modified vs unmodified dryset thinset here fourteen months later everything looks good so far.

Don bell denver co. Or is priming of the concrete substrate unnecessary. I can see maybe some value as the floor has a join of 2 different materials. The floor is a 4 poured concrete slab on grade with moisture barrier and 2 sm insulation under the concrete.

I think the benefit far outweighs the cost. 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. The ditra will cost approx. For installing tiles on ditra.

3 000 and i am not sure if we really need it on a concrete slab. If i find myself needing to tile over anything other than new level concrete i ll probably go with ditra again. 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.

About to tile a concrete floor in the basement of a home. 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. Use our ditra heat calculator to find out what products you need to complete your specific installation.
