If a subfloor displays excessive deflection. it can usually be remedied by installing more plywood on top of it before tile is laid. and by reinforcing the joists from below. While it may make the floor higher than before. think of it as a sort of `insurance policy` against flooring failure.
There are formulas used in the industry to determine if the subfloor has excessive `deflection` [bounciness. lack of rigidity]. The most cited one is the Tile Council of North America standard for deflection. which is stated as L/360 as a minimum. before tile underlayment is installed. L/360 means that the floor should not bend under weight more than the length (expressed in inches) of the unsupported span divided by 360. For example. if the span between supports runs for 20 feet then the deflection should not be more than 2/3" between the center and the end. L=20 x 12" = 240". L/360 = 240"/360 or 2/3". So 2/3" is the maximum amount of movement the center of the span should be allowed to move.
Install the Ceramic Tiles. Start with the center and move outwards with each ceramic tile. Use thin set mortar or tile adhesive to set the tiles. make sure that the bond between the tile and the sub-floor sets by applying pressure on each tile. After the tiles have set. complete the process by applying the grout. Remember that the grout must be of the same color as the tiles you have chosen. Remember that each step requires twenty-four hours to set and dry before allowing yourself to proceed to the next step of your ceramic tile flooring installation.
In residential settings. the most common substrates [surfaces to be tiled] for flooring are wood and cement. In this article we`ll deal with deal with wood subfloors. In new construction. it`s often possible to see the structure of the subfloor and joists and usually communicate with the carpenters who built them or the contractor in charge of the project if there are any questions. In remodeling. however. sometimes one can only guess who installed the floor and how strong it is. Maybe it`s as strong as a battleship. or maybe it`s about to fall through to the basement. If a property owner is trying to install the floor himself. he or she may wonder how to know if the subfloor is strong enough. Let`s start with the technical and then translate it to the everyday way to tell.
