Ditra over hardwood flooring.

I have not contacted schluter yet. Please give us a call so we can discuss your options and get you the best system for your application. Unlike hardwood floors where a bit of flexibility is desired tile surfaces need rigidity. 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.

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. The 3 4 hardwood is on top of 7 8 tungue and groove plank flooring. 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.

I m ready to start tiling in an old house 3 4 subloor with 1 1 2 x 3 4 oak flooring. 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. However we have a number of other products that can be used under lvt. Floor joists are 1 75 x 9 16 oc longest support span is about 12 feet.

The floor slopes down to one corner by 3 4 over 3 feet you can see this in the shower picture. The subfloor is 3 4 x 7 tongue and groove plank with some knots set on the diagonal. The combination of tiles and grout would break up over time with a flexible underlay. I plan to use the thinner ditra uncoupling membrane.

In spots the last install used leveling compound some of this broke and pulled up with the tiles. Underneath is a 3 4 maybe 1 plywood subfloor over the top of the original subfloor. Minimizes total thickness of the installed floor and this reduces the transition to flooring that is lower such as vinyl carpet or engineered wood. First time floor diy i would like to install porcelain stone or thin brick on my 1955 kitchen and hall floor.

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. 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.
