A great tile installation is not possible without a flat floor. Prior to 1 piece of tile going down, we work to make sure that we have a level substrate. Next, if there are any concrete issues (surface cracks or control joints) they are addressed. Layout is the next step. It is imperative in achieving the look you are striving for. As part of this process, we go over base board, tile direction (north-south, east west) and layout type (straight set, staggered, diagonal, third offset or random and grout spacing). Manufacturers specs and physical inspection indicate what is and is not possible. After selecting the proper thinset for the application (LFT, modified, non sag, etc) installation begins.
