Step 1 of 6: Checking & Cleaning The Floor

Check how much unevenness is on the floor. Lay a metal bar horizontally to measure the unevenness. However, before you do this make sure you’re wearing protective gear. Otherwise, you might hurt yourself in the process

Before we start with leveling the floor, get rid of any dirt or debris. This is because it might get in the way of the process. 

So take a broom and clean the area thoroughly. Then use a vacuum to collect the dirt and debris. After that, you can take your hammer and strike off any nooks and crannies. You can also use a chisel to break off the stubborn ones. 

After that, take your decking tool and clear off the rest. If there are any leftover paints, use paint remover to clean them. Then use the vacuum to clean off all the dust. Your floor is now ready for primer.

After you’ve cleaned the floor, it’s time to prime it. It’s important to use a good one for this process. Because a cheap one might not work well with the self-leveling compound. 

Thus we’ve suggested some of the best ones you can use for this:

Product 1
Product 2

You can use any of this in the priming process. Moreover, you can rest assured that this product can support the pressure of the floor. 

Now, mix in the primer. You should always use the instructions given in the box to mix it. Otherwise, your primer might not hold the floor. Plus it can cause structural problems later on. Hence follow the proportion carefully. 

After that, pour the mixture onto a rectangular tray. Use a rolling brush to apply it all over the tiles. 

Step 3 of 6: Mixing The Self-leveling Compound

After applying the primer, it’s time to use a self-leveling compound to correct the unevenness. You can use a self-leveling mix to do this process. Read the instructions on the manual to combine the compound. 

You have to pour in the mixture starting from the lower part of the room. Then use a trowel to spread it out evenly. Make sure it fills in all the nooks and crannies. Check if you’ve missed a spot between your foundation wall and slab.

Moreover, you can also add an extra litre of water to help spread the mixture faster!

Step 4 of 6: Checking If The Floor is Even

After the waiting period you have to make sure if the floor is even. Check for gaps and unevenness. If there’s any, add a light layer of the compound mix. Don’t worry if the floor is wet, because you can still pour it in. 

Again wait for it to dry, after that you can proceed with mapping the 

Step 5 of 6: Mapping The Floor

It’s finally time to start mapping the area to tile it. This will help you know how many tiles to place there.

You can use a marker or chalk to mark straight lines. In this way you can make sure the tiles are aligned. 

Step 7 of 7: Tiling, Grouting & Sealing

Now, it’s time to lay the tiles. You can use the type of adhesive you prefer. However, make sure to mix it well following the instructions. Then apply the mixture using a rubber mallet and place the tile. 

Follow this method to complete the entire room. After that wait for at least a day or two for the tile to dry. Then you need to start grouting.

There you go, this is how you can renovate an old room by tiling an uneven floor. 


Question: How do you level tile when installing?

Answer: To do that, make sure that the surface is as flat as possible. But if you want to take it a step further, use a suction pump. This will keep the tile flat. Plus it will add even pressure to the tile keeping it extra flat and still. 

Question: Should you wet tiles before laying?

Answer: If you are thinking of soaking the tile before placing it, then it’s not necessary. You can just splash it with some water and it’s good to go. You can use rags or sponges to wet the surface of the tile as well.

Question: How thick should floor tile adhesive be?

Answer: Most of the adhesives are cement-based and sit around 3mm to 12mm. This is a standard measure. If you have bigger tiles with a larger area, you should go with the highest thickness. For the smaller one you can go with the thin one.
