If you are in a situation where you have a ceramic tile floor that needs replacing, you have a few options at your disposal. First of all, you can decide to take up all of the old tiling and replace it with a completely different type of flooring. However, if you already know that you would still like to use tiles but with a more modern look and design, you could save yourself a lot of time and effort by installing new ceramic tiles over the old ceramic tiles.
If you are going to install new tiles over old ceramic tiles, there is a little bit of preparation work that you will need to do. This preparation and planning will make the overall job much easier for you to do and it will give you more of a chance of success.
Define your Project
The first thing that you must establish is the size of the area that you will be tiling. Measure the area as accurately as possible and when you go to the store, be sure to purchase more tiles than you will actually need for the job. Extra tiles can be used to correct mistakes and they can also be stored once the job has been completed for use at a later date should a tile crack or pop out of place.
Do a bit of shopping around to find out what your latest options are in ceramic tiles. Find a design that you not only like but that will fit well with the current decor of the room that you will be re-tiling. Purchase your new tiles and have them ready and at your disposal before you begin work.
The first thing that you will need to do in the process of installing your new ceramic tiles is to sand down the tiles that are already on the floor. Be sure to sand the floor well using 80-grit sandpaper. You need to roughen the surface of the existing tiles so as to give the new tiles something to grip on to.
As prepare to line up the new tiling, you will want to ensure that the seams of the new layer of tiles are not lined up with the seams of the previous tile floor. Therefore, before you do anything else, lay your new tiles across the room in the shape of a cross. This will tell you how many tiles are needed for the length of the room and how many are needed for the width of the room. It will also show you how the new layer of tiles should be placed.
Before starting the work of laying down your tiles, use putty to fill in any obvious dents and holes that exist in the current floor. Then vacuum up any loose pieces that may still be on the floor from the sanding that you did.
Next mix your mortar. You should only make only enough mortar for one hour of work. This will ensure that the mortar does not begin to set before you have had a chance to use it. Also, be sure to make grooves throughout the mortar so that tiles will lay evenly across the floor once placed on it.
You will lay down your ceramic tiles in sets being careful to keep things lined up properly. Be patient as laying tiles is not an easy job and it is not a job that can be rushed. Once all of your tiling has been laid, you will need to leave it to set. Be sure to check your packaging to find out the standard setting time for the mortar that you buy. Once the mortar has fully set, you will be free to grout the tiles as usual.
