Ditra Over Hardwood Flooring

However we have a number of other products that can be used under lvt.

Ditra over hardwood flooring.

The 3 4 hardwood is on top of 7 8 tungue and groove plank flooring. In spots the last install used leveling compound some of this broke and pulled up with the tiles. The combination of tiles and grout would break up over time with a flexible underlay. I plan to use the thinner ditra uncoupling membrane.

Floor joists are 1 75 x 9 16 oc longest support span is about 12 feet. 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. They are both structurally in good shape. I have not contacted schluter yet.

The subfloor is 3 4 x 7 tongue and groove plank with some knots set on the diagonal. 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. We recommend removal of the finished hardwood flooring and then following the applicable ditra handbook detail. Now someone told me i can t put ditra over hardwood.

I m ready to start tiling in an old house 3 4 subloor with 1 1 2 x 3 4 oak flooring. Everything thing is solid screwed thru the floor to the joists and sanded clean. Unlike hardwood floors where a bit of flexibility is desired tile surfaces need rigidity. The floor slopes down to one corner by 3 4 over 3 feet you can see this in the shower picture.

The ditra heat floor heating system is designed for use under tile and stone flooring only. The floor was a cheap glue down laminate tile that i pulled up. Please give us a call so we can discuss your options and get you the best system for your application. 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.

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. Underneath is a 3 4 maybe 1 plywood subfloor over the top of the original subfloor.
