Ditra Over Hardwood Flooring

Now someone told me i can t put ditra over hardwood.

Ditra over hardwood flooring.

My main concern was whether is was okay to put thinset directly on an old hardwood floor and if i should use an unmodified thinset between the hardwood and the ditra followed by modified between the ditra and tile. I plan to use the thinner ditra uncoupling membrane. Everything thing is solid screwed thru the floor to the joists and sanded clean. Minimizes total thickness of the installed floor and this reduces the transition to flooring that is lower such as vinyl carpet or engineered wood.

I have not contacted schluter yet. 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. The subfloor is 3 4 x 7 tongue and groove plank with some knots set on the diagonal. The 3 4 hardwood is on top of 7 8 tungue and groove plank flooring.

We recommend removal of the finished hardwood flooring and then following the applicable ditra handbook detail. 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. The ditra heat floor heating system is designed for use under tile and stone flooring only. 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.

Underneath is a 3 4 maybe 1 plywood subfloor over the top of the original subfloor. 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. I m ready to start tiling in an old house 3 4 subloor with 1 1 2 x 3 4 oak flooring. First time floor diy i would like to install porcelain stone or thin brick on my 1955 kitchen and hall floor.

In spots the last install used leveling compound some of this broke and pulled up with the tiles. However we have a number of other products that can be used under lvt.
