Ceramic Tile Flooring - Do I need a Backboard?

Installing ceramic tile is not as difficult as you may think. The most important step is to prepare your floor for the tile. You do not need to tear out old linoleum unless is it cushioned or has large areas missing or torn. Old tile must, of course, be removed. It is important to have a good base , or your tile may crack with use. If you are laying tile over any concrete floor, you do not need any additional support. However, any other floor probably needs a concrete backer board so the total floor thickness is enough to support your tile. The total floor thickness beneath your tile must be between 1 1/8 and 1 , depending on how far apart your joists are spaces.

The thickness of the backer board depends on the spacing between your floor joists and the thickness of your floor. You will have to go into your basement or crawl space to determine the joist spaces. If your floor joists are 16 apart, you will need at least 1 1/8 of total floor thickness. Joist spaces 24 apart require 1 of flooring. You can measure the thickness of your floor by removing a floor register. You can also just drill a 1 hole in your floor and measure the thickness of the hole. Backer board usually comes in and thick 4x8 foot sections.
