What Can Cause Uneven Tiles?

There is a multitude of reasons why a tile can become uneven. It can be either because of your own carelessness or due to uneven surfaces. But the most common is usually the latter one. In the former situation, you might have squeezed in the tile too much. Or you might have put in an uneven layer of mortar or Thinset. But these problems can be solved if you reinstall the tile. Of course, reinstalling a tile is too much work.

Instead of reinstalling the tile, you can just apply the grout to the tile in a way that does not cause impediments. In the latter situation where the ground is uneven, you can always even out the ground by filling it with plaster ahead of time. But when you are doing it yourself, mistakes are bound to happen. You might miss a spot or two and the tiles become uneven there.

Instead of doing it all over again which is a lot of work in all honesty, you can just grout the uneven tiles. When you do so, the tile will feel much more normal in all honesty. You will end up saving time, which you would have wasted to remove the tile and the Thinset and lay them again. And you will save the money that you would be wasting as well.

How to Grout Uneven Tile Using Technique

For this you just need a few things, you will need clean water, a large bowl full of it. A sponge that you will use to apply the water with. Grout, which is a mixture of cement and sand. It can also be premade or you can mix it yourself. Additionally, you will need a concrete float as well to spread out the grout the way you want to.

Step 1 – Preparing the Grout

First of all, you need to prepare your grout. It will be in powder form, you can mix the ingredients yourself or get it premade. Either way, you have to mix water in the grout and create a consistency where it is more like a thick dry paste. Don’t end up putting in too much water or you will make it too thin. And thing grout is useless, it does not stick properly.

Step 2 – Wet the Area Around the Uneven Tile

Use the sponge and wet it, don’t wet it too much though. Just wet it enough that it can make the tiles wet a bit.

Step 3 – Placing the Grout

Now, you need to take your float tool, put the grout on it, slowly layer it between the uneven tile and the even one. Once you layer it there, you need to tilt it at a 45-degree angle facing away from the uneven tile. Now slowly move the concrete float tool from the even tile to the uneven one slowly. This will fill in the unevenness from the tile.

Step 4 – Removing Excess

Now slowly take your sponge, wet it again in the same way, not too wet just enough. Take your sponge and slowly move it in the same position and angle as you did with the floating tool over the grout. This will make it even more even and remove any excess grout. Do it slowly and steadily, if your sponge is firm enough, let it do the work. Spread out the grout evenly and slowly hydrate it so you can manipulate it further if needed.

Step 5 – Clean off the Sides

Now take the same sponge and clean off the sides which do not require the grout. Use the same amount of water and clean off that grout properly so that it does not dry off before you can clean it off. You can additionally use rags and ensure that the grout is cleaned off properly.

Once the grout has dried off you can check if it is leveled or not yourself. Although we are pretty certain it will be leveled because you filled the uneven gap between the tile with the grout itself. It might give off an unfinished look, like an area that has more grout than the other.

But let’s say these are bathroom shower tiles, then putting the grout in that position will save your shower from leaking in the future. Besides, it will be almost unnoticeable. A fair bit of warning though, if the ground is uneven and you are tiling it regardless, make sure that there is enough mortar under it to adhere it to the ground properly. If there isn’t enough mortar, the tile can break under pressure.


An uneven tile should not be a problem for anyone. Mistakes are bound to happen and fixing them is what the DIY spirit is about. Doing it yourself and fixing such mistakes is part of the whole process. You should not redo the thing but instead just fix it when it is done. Grouting an uneven tile is just about that, instead of taking out the uneven tile and fix that issue, you can just grout it in a way that does not feel out of place.

As we mentioned above, there are countless reasons why a tile can be uneven, specifically if it is an old house there are bound to be a few uneven tiles. So instead of fixing the whole floor, which is time-consuming not to mention it will also take a lot of resources and money, just fix the uneven tile. If it is just one tile, all the more reason to ignore it and just grout it in a way it does not impede movement.
