What condition does the wood appear to be in? Even if the amount of wood support seems adequate according to the tables. if it appears to have been water damaged. if sections of it look moldy or corroded due to rot or decay. it`s not doing its job. Options include replacing or reinforcing it. but not just ignoring it. Also. has it been cut into in various spots. such as a plumber cutting sections of the joists for positioning pipes? All of these problems can make the wood less effective.
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.
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.
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.
