About to tile a concrete floor in the basement of a home.
Do i need ditra on concrete floor.
Over concrete or gypsum use unmodified thinset mortar.
If i find myself needing to tile over anything other than new level concrete i ll probably go with ditra again.
Use our ditra heat calculator to find out what products you need to complete your specific installation.
Using ditra normal cracking which occurs in concrete slabs will not adversely affect your tiled floor.
We also have an in floor glycol heating system.
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.
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.
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.
Adding ditra to a tile flooring job will cost about 2 per square foot.
3 000 and i am not sure if we really need it on a concrete slab.
Given concrete is pretty solid and the additional cost for laying ditra matic is substantial is it really necessary.
Installing tile directly on concrete.
Or is priming of the concrete substrate unnecessary.
Plan to use ditra mat which i ve laid several times before.
I think the benefit far outweighs the cost.
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.
Use unmodified thinset mortar learn about modified vs unmodified dryset thinset here fourteen months later everything looks good so far.
My only question is do i need to necessarily prime the concrete before then using thinset into which to embed the ditra mat.
We have just been told that we will need to lay ditra matic under the tiles.
I can see maybe some value as the floor has a join of 2 different materials.
I don t insist on ditra or any other uncoupling membrane when tiling over concrete floors but i do recommend it.

Yet this application does make sense since concrete is heavy solid and is typically thought of as an unbending uncompromising material.
