Flooring

We are redoing our kitchen and we are at the floor part (we left it for last). we stripped the floor down to the original sub-floor. we were going to put cement boards and then install the tiles on top of that but the subfloor was very week. we installed 1/2 inch boards of wood and we are unsure about the next step. Should we put cement board and then the tile or we saw a product that might be a good option. the Schluter Ditra. does anyone have any experience with this product or opinions on how we should proceed. If we use the cement board the kitchen floor will be higher then the other floor it meets. there are solutions to this but we want to try and keep it simple. thanx

Re: Flooring

the top priority is to make sure that the sub floor is rigid enough to accept the cement board. this is not done by adding 1/2 plywood on top of the sub floor but by strengthening the floor joists below. if there is any bounce at all to the floor, prior to installing the cement board, the grout or tiles will eventually crack. without seeing your space and examining things, i would recommend sistering new joists to the existing ones to give you the rigidity you need for the cement board. after the sub floor is all set, you can install 1/4" cement board, instead of 1/2", to lower the transition between your new tile floor and the surrounding floors.

Re: Flooring

we already strengthened the sub floor but it wasnt enough. it couldnt be strengthened in all the spots cuz of pipes in the way ect.

Re: Flooring

in the spaces where you can't sister another joist, you can use blocking and cross bracing to stiffen up the floor joists.

John bridge Tile Forum has a lot of useful information, including the formula to determine your floor deflection. Knowing this will enable you to choose a course of action, because right now your floor can't take tiles with cement boards.
