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.
How tough is the tile to be installed? Fairly thick quarry tiles. for example. may be rated for heavy duty industrial applications. although they are often installed in homes. Because they are thicker than normal tiles and able to withstand heavy traffic. they may be less prone to cracking than a sensitive. thinner tile. For that matter. natural stone such as marble and granite are on the other end of the spectrum - they crack even easier than ceramic tile and should not be used in settings where any excess deflection is possible. Intuition may tell you they are stronger than ceramic. but in fact they are more brittle and prone to cracking. They need twice as rigid a floor as ceramic.
Knowing the kind of subfloor you`ll be installing ceramic tile flooring over is important. There are three main types of subfloors you might encounter: Vinyl. plywood. and concrete floors. Installing ceramic tile flooring directly to your vinyl or linoleum subfloor surfaces is greatly discouraged. One. it may contain asbestos fibers; and two. vinyl flooring is not a solid as good ol` concrete flooring. When installing ceramic tile on vinyl. experts would recommend rough-sanding. or scarifying. the vinyl floor surface first so your tiling mortar has good grip to set on.
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.
