How to Prep for a Ceramic or Porcelain Tile Floor


Porcelain and ceramic tile flooring is beautiful, durable and easy to clean—especially in the high traffic areas in your house.

The following instructions will show you how to lay the cement backerboard underlayment for a strong foundation under your tile flooring.

    at the 1:00 minute mark in this video, it shows someone trowelling white mortar on what seems to be vinyl or canvas flooring. This should never be done,the floor would never last. as for cemeting sheet rock to the floor, its much cheaper and easier to use SCHLUTER DITRA. search it up, you’ll ind it on youtube.

    @ Like YA Would…It’s a vinyl floor and the methods are correct for a cement board application.

    what ever you are or think you are …it’s not a flooring expert, for sure…

    @LikeYaWould see 3:34 they used screws to hold the backer board down.

    Only thing I disagree with is undercutting the door trim (jamb). it gives a better look to take off the whole trim and cut off the bottom to size when the tile job is complete. Plus it’s a little easier to lay down those edge tiles without having the trim in the way.

    @juxtapos99 I think it’s easier to cut the door jambs and just slide the tile under it.

    Union tile finisher for over 10 years and installed miles of cement board. It is not correct to install any underlayment over vinyl flooring thin set and screw or not. Take the hour and rip it up, this is just lazy and cutting corners. Why risk all your hard work for possible failure. One other point, learn how to square your room and not have so many cuts. Try to have a full tile at your tub and doorway. No need for cuts on every wall.
