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
