Whether you're laying floor or wall tiles, you will have to apply tile grout. While the thickness of the grout line can differ depending on the tiles and your own tastes, your tiles must be grouted in order to ensure the surface is strong and waterproof. Read on to find the ideal grout for your tiles!
- Finely sanded tile grout
- Flexible grout
- Epoxy-based grout
Technical features of tile grout
Tile grout always comes in powder form and is designed to be mixed with water, just like tile adhesive. Tile grout is a cement-based product. It's important to add the right amount of water to grout to ensure that it lasts as long as possible. The grout line for non-rectified tiles is generally around 4/5 mm thick. The only case in which you can use a thinner grout line is with rectified tiles which have very straight edges. In this case, the grout line can measure about 1 mm on the wall and 2 mm for floor tiles. The amount of tile grout you need depends, of course, of the thickness of the grout line. Be sure to follow the manufacturer's instructions so as not to mess up your grout mix!
Different types of tile grout
Finely sanded tile grout
Thinner grout lines are generally the most popular option and will work just fine for rooms around the house. You can choose from a wide range of shades, but the most common tones are light greys and whites. That said, it all comes down to the tiles you choose and your preferences in terms of style.
Flexible tile grout
It's best to go for flexible grout for some types of application such as underfloor heating, outer walls, wooden floors and so on. This type of grout is suitable for any surface that might move.
Epoxy-based tile grout
Epoxy-based tile grout is also designed for certain specific applications. This type of grout is essential for public spaces with heavy footfall and in any area that has to withstand chemicals. Epoxy-based grout can also be used around the house in bathrooms (particularly around showers) for both walls and floors as it is absolutely watertight. If using this type of grout, it is essential to use an epoxy-based adhesive as one can't be used without the other!
Mixing grout colours
These days, manufacturers have no shortage of ideas for different products, tile grout included! Even if you want to go for grey or white grout, you'll have some 50 different shades to choose from! Otherwise, from light brown to deep chocolate, green, blue or yellow, there's a world of choice out there! Don't forget that professional tilers can also mix their own grout with colourants to get as close as possible to the tiles you've chosen.
Tiles should be grouted 24 hours after your tiles have been installed. You simply need to fill the spaces between each tile using a grout float and, most importantly, wipe away the excess with a sponge float. It is possible to buy full grouting kits and these prove very handy. After your grout has dried, you must remember to clean the surface thoroughly using specialist cleaning products.

When I was young, I was already working in the family garden. Perhaps that is where my interest in plants and gardening came from. So, it was logical for me to study both plant biology and agronomy. At the request of various publishers I have, over twenty-five years, written many books on the subject of plants and mushrooms (a subject that is close to my heart).They were mostly identification guides at first, but shortly after they were about gardening, thus renewing the first passion of my childhood. I have also regularly collaborated with several magazines specializing in the field of gardening or more generally in nature. There is no gardener without a garden, I have cultivated mine in a small corner of Cambridge for the last thirty years and this is where I put into practice the methods of cultivation that will I advise you in as well.
