In spots the last install used leveling compound some of this broke and pulled up with the tiles.

Ditra over hardwood flooring.

I plan to use the thinner ditra uncoupling membrane. I have not contacted schluter yet. The ditra heat floor heating system is designed for use under tile and stone flooring only. We recommend removal of the finished hardwood flooring and then following the applicable ditra handbook detail.

Underneath is a 3 4 maybe 1 plywood subfloor over the top of the original subfloor. Allows you to install ceramic tile over a single layer of plywood or osb subfloors on joists with wider spacing such as 24 inches on center. We don t recommend or warranty ditra or ditra xl installation over existing hardwood flooring as it is very unstable and difficult to bond to making it a poor substrate for tile. First time floor diy i would like to install porcelain stone or thin brick on my 1955 kitchen and hall floor.

The 3 4 hardwood is on top of 7 8 tungue and groove plank flooring. The combination of tiles and grout would break up over time with a flexible underlay. Ditra xl is 5 16 7 mm thick to create an even transition between typical 5 16 7 mm thick tile and 3 4 19 mm thick hardwood flooring ditra xl allows for ceramic tile application over single layer plywood osb subfloors on joists spaced at 24 610 mm o c. Floor joists are 1 75 x 9 16 oc longest support span is about 12 feet.

I m ready to start tiling in an old house 3 4 subloor with 1 1 2 x 3 4 oak flooring. However we have a number of other products that can be used under lvt. Therefore denser more solid materials like schluter ditra xl s rubber underlay are the best choice for providing a solid foundation to keep the floor protected. Unlike hardwood floors where a bit of flexibility is desired tile surfaces need rigidity.

Now someone told me i can t put ditra over hardwood. The subfloor is 3 4 x 7 tongue and groove plank with some knots set on the diagonal. The floor was a cheap glue down laminate tile that i pulled up. Everything thing is solid screwed thru the floor to the joists and sanded clean.

They are both structurally in good shape. Minimizes total thickness of the installed floor and this reduces the transition to flooring that is lower such as vinyl carpet or engineered wood.
