I want to nonetheless utilise tile but I wanted to know whether you lot lay ceramic tiles over existing ceramic tiles. I asked some tilers and here's what they said.
It's perfectly fine to lay ceramic tile over ceramic tile. But, if the tiles are particularly damaged, or you identify air pockets in the tiles, then it'due south best to remove them. Air pockets betoken the tiles were installed incorrectly and will need replacing very soon.
There are a range of subfloors that can be used for ceramic tiles. The most common are plywood, and concrete. Simply, it'southward also possible to tile hardwood floors.

Since information technology's perfectly fine to lay ceramic tiles over ceramic tiles, I was curious about how ceramic tiles compare to the other types of subfloor, and whether it'southward a good thought. Co-ordinate to builders and tilers here's whether you should or non.
Mostly, it'southward a good idea to lay ceramic tiles over ceramic tiles. The main concern with laying ceramic tiles is the subfloor is stable, level, and flat. Ceramic tiles demand to be inspected before laying ceramic tiles on top to ensure they are level, and installed correctly.
Testing tiles to run across if they are installed correctly is done by borer the top lightly. Use your finger or a light coin like a quarter to tap on the surface of the tile. Where there are air pockets you will hear a hollow sound.
Air pockets are created when the glue wasn't applied using the best technique, or non plenty glue was used.
Tiles with air pockets neglect much faster than tiles that are installed correctly. Then, if y'all discover the tiles were installed incorrectly you may decide to remove them and start fresh.
It should be treated every bit a instance by case ground depending on how much of the tile floor has air pockets, every bit well every bit, the overall weather of the tiles.
Generally, laying ceramic tiles over tiles saves labor cost/time which means the task will be cheaper and take far less time than removing the existing tiles.
But, some people prefer to remove the existing tiles for their ain piece of mind in cases where they don't know who installed them, and what's underneath.
How to Install Ceramic Tile Over Ceramic Tiles
As an avid DIY'er I've installed tiles before. Only, I was curious if in that location are any considerations when it comes to installing ceramic tiles over ceramic tiles, equally well as, what the general process is. Here'south what I plant.
The steps involved in installing ceramic tile over ceramic tiles are:
- Ensure the existing ceramic tiles are flat, and level
- Lay out the tiles on the floor to see how they will fit
- Apply tile mortar to the existing ceramic tiles
- Lay the tiles
- Grout the joins
There's some tools which you lot'll need they are:

1. Ensure the existing ceramic tiles are flat, and level
The surface that yous install tiles onto needs to be level otherwise the resulting tile flooring won't be level. Apply your carpenters level to check the existing ceramic tiles to encounter if they are level.
A piffling bit off here and at that place is OK. Only, anything that you can visibly see or obvious high and low points in the floor should exist addressed using a cocky leveling chemical compound. Self leveling compound is fabricated past mixing the self levelling compound powder with water and pouring it onto the flooring. Every bit information technology dries it will level itself out.
Y'all can also build upwardly areas, and make full in imperfections using filler. There are many dissimilar kinds and brands available from your local hardware store. A generic builders/tilers putty or filler works well.
iii. Lay out the tiles on the floor to see how they will fit
Once the floor is apartment and level you should lay out the tiles to come across what configuration will fit the best. The full general thing you want to avoid is having a thin slice of tile at the edges where the floor meets the wall.
An piece of cake way to lay them out is to kickoff with one row of tiles downwards the middle. Then lay out the residual of the tiles. Adjust where the middle row is so that the finish tiles are the biggest size possible.
For example you may find that you need to start with half a tile on one wall to get one-half a tile on the contrary wall. Or, that if you start with a full tile on ane wall, the opposite wall volition finish upwardly being a half tile.
4. Apply tile mortar and lay the tiles
Now that you know how you're going to lay the tiles, you tin now begin applying mortar. Mortar acts like mucilage and sticks the tiles to the subfloor.
The USA National Tilers Clan has put out a video explaining how tiles are affected when mortar is applied using the different trowel patterns. Also every bit, the best method for applying mortar for tiles.
Here'due south the video:
I know a few tilers here locally and they accept said that they come up across projects from fourth dimension to time that have been tiled incorrectly, and as a issue they had to exist repaired at an extra expense.
Only follow the instructions in the video above to run across exactly how you should apply the mortar and identify the tiles on the mortar.
half dozen. Grout the joins
When you lot lay your tiles, yous will utilize spacers to go along the altitude between each tile even. But, there will still be a space in between the tiles that needs to be filled with grout. After 24 to 28 hours the mortar underneath the tiles will accept stale and y'all tin remove the spacers. Now, y'all need to apply grout to the spaces in between each tile.
Grout is moist and soft and is similar to working with clay used in pottery. Yous can apply it to the spaces in betwixt the tiles using a trowel, and use a wet sponge to fifty-fifty it out.
Make the surface of the grout smooth and even by wiping the top of the tiles and the grout lightly with a wet sponge. There tin be some grout residue that will only get visible in one case it dries a piffling scrap. Y'all volition see a fine grit finish on the acme of the tiles.
Take a clean moisture sponges and wipe the surface of the tiles once again to remove information technology. As you exercise then, endeavor not to bear on the grout in the joins as it will nonetheless be soft and moisture. Grout takes 1 to three days to completely dry depending on the temperature and humidity.
