Why Remove Grout from Floor Tiles?

When the time comes to retile a shower or bathroom, you may be faced with an issue. The grout that was used to seal the tiles will probably have hardened quite a bit. 

Grout is meant to be waterproof and as a result, can be very difficult to remove. While this generally means the grout was installed correctly, it can be frustrating. 

Luckily, there are ways that you can remove the old grout and even save the tiles in the process. 

By being very careful during the process, you can successfully remove the old grout. However, it is important that you work carefully and try not to break any tiles by being too forceful. 

Soak the Grout

No matter how you are going to remove the old grout, you should soak it first. 

Mix a solution of one cup of sugar with a gallon of warm water. Then, soak the grout with the solution for several hours. The amount of time you need to leave the solution will depend on how old the grout is. However, you should plan on leaving it for at least two hours. 

Soaking the grout in the sugar and water solution will soften it up. This will make it easier to remove no matter how you are doing it. 

Remove it Manually 

It’s possible to remove grout using a manual tool

Grout removal tools usually look like a screwdriver with a bent blade. These blades are made of carbide and are very hard. 

To remove the grout, slide the tool along the center of the seam. This will start to cut through the dried grout until it can be removed. 

There is another type of grout removal tool as well. These look more like a small saw and are made of the same material. 

To use these, simply saw into the grout manually like you would with anything else. The hardness of the carbide makes it easier to cut through. 

It’s important to note, however, that this method will be more likely to damage the tile. It’s hard to work intricately with manual tools like this. 

Use a Reciprocating Saw 

A reciprocating saw is a great tool for all kinds of applications. 

With a reciprocating saw, the blade moves back and forth just like with a manual saw. However, it is powered and much more effective on harder materials. 

Use a carbide blade to cut through grout with a reciprocating saw. 

Simple cut through the grout like you would with a piece of wood. However, you will want to make sure that you don’t cut down into the subfloor. 

As you make your cuts, check your work to be certain that you’re not making them too deep. 

Use a Dremel

A dremel is perhaps the best tool to use to remove grout. 

With a dremel, you can use a carbide cutting blade to slice the grout through the middle. This will loosen the grout so you can get it out. 

You can also use other bits on the dremel to remove grout from the sides of the tile. This is the best way to get the whole thing completely cleaned and ready for new grout.
