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.
Measure Everything. The next step of your ceramic tile flooring installation is the accurate measuring of your floor and your tiles. This is necessary for you to be able to calculate exactly how many tiles you will need. You must measure the length and width of the section of floor you are going to tile and also the length and width of each tile. Then you must calculate. using these numbers. exactly how many tiles you are going to use. which will depend on the orientation of each tile as you have decided to place it on the floor. as well. Then you must find the mid-points of the length and the width of the floor you want to carry out your ceramic tile flooring installation process on; connect these midpoints to form a plus across the floor space. The intersection of the two lines of the plus is the center of your floor space; it is here that you must begin your ceramic tile flooring installation.
For plywood subfloors. be sure that the wood is at least 1 and 1/8 inches thick and is supported by an equally strong underlayment. Otherwise. your ceramic tiles will dislodge easily. or worse. break and need replacing. Concrete floors are the most ideal subfloor surface to work with. But before you can start installing ceramic tile flooring over it. it must be cleaned thoroughly. For dust and other debris. sweep and then mop your concrete subfloor surface. and allow it to dry completely. Smooth concrete surfaces must be rough sanded just like vinyl floors to allow the tiling mortar some grip.
Glazed and Unglazed Tiles. Firstly. there are glazed and unglazed tiles; the glazed tiles can be cleaned very easily and do not stain as often as unglazed tiles. All you need to do is run a mop soaked in warm water with a mild detergent solution across them from time to time. The problem with glazed tiles is that they are very smooth and therefore can be quite slippery. This is dangerous. especially if the kitchen area is prone to water spillage or if there are young children in your home. To avoid this. you could choose unglazed tiles over glazed ones. Unglazed tiles will prevent the floor from being slippery and have an aesthetically pleasing textured surface. Then again. unglazed tiles will not be as durable as glazed ones - they will be relatively more prone to damage because they are not protected by that extra layer of glazing.
