How thick is the subfloor and what is it made of? In new construction. ¾ inch plywood or Oriented Strand Board is a standard subfloor over joists that are 16 inches on center apart. We find that is almost never enough to meet the deflection standards in most homes. Other times there is old plank flooring beneath a layer of plywood. This is a wild card. since the engineering tables usually don`t include the value for planks in their calculation. but common sense says it does add some stiffness.
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.
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.
Is there an unfinished ceiling below to look up and measure the distance between joists and the condition of the wood below and how long the unsupported span is? A few minutes in the basement with a flashlight and tape measure can let you know if you have a winner (thick and deep joists. spaced closely together. in good condition. with a narrow span). or a loser (thin and shallow joists. irregularly spaced or spaced far apart. in bad condition. with a long span).
