What is the purpose of grout?

Grout is an elastic bond put between ceramic wall or floor tiles. Its main purpose is protection of the elements as well as their decoration. The most important role of grouting is hiding any differences in size between tiles. Without grout the cracks between tiles are more visible, which has a negative impact on the appearance of the surface.

Apart from decoration, the product secures the tiles against damage and harmful external factors. It protects floors and walls from humidity and prevents accumulation of dust and dirt in the gaps. It also hinders growth of fungi and mould. Filling the gaps with grout increases the grip of tiles to the surface.

Grouting is very useful when one tile needs to be replaced. Thanks to this product it is possible to take out the broken tile without damaging the rest of the surface.

Groutless floor tiles - is it possible?

One of the most common questions posed by aesthetes and minimalist design lovers is whether it is possible to lay tiles without grouting. Can it really be done? The answer is: yes! How to do it? You need to use special rectified tiles. Rectified tiles are cut during the production process so that their edges are perfectly even.

Rectified tiles are perfect floor tiles for kitchen and bathroom. Such flooring looks best in spacious rooms, which bring out the elegance of a smooth surface. The tiles are excellent for minimalistic interiors, where furniture and decorations are limited. In such design the tiles are the main decorative element.

A flawlessly smooth surface looks good also in smaller interiors. If the set of tiles is chosen properly, it might make a room look bigger.

Floor tiles with invisible grout

Rectified tiles are the best solution in terms of appearance. They are, however, not very practical, therefore most professionals recommend using so called “invisible grout” when laying the tiles. It is a very thin line, less than 2 mm thick.

Such grouting is very subtle and quite difficult to notice when using the floor - one needs to get a closer look to see it. This method is not very different from laying rectified tiles, although it’s less practical, as the surface is not perfectly smooth. It also impacts the strength of the flooring.



Floor tiles without grout - risks

Laying floor tiles without grouting makes the surface more vulnerable and prone to damage. Tiles without grout lose their grip, so laying them is more complicated. There is also a threat that an element breaks, splits or worse - completely comes off the surface. Groutless floor tiles make it easier for humidity, fungi and bacteria to get inside of the wall.

One of the biggest disadvantage of floor tiles of this type is the fact that it is impossible to remove just one element without breaking the rest of the tiles.

Will all types of floor tiles serve the purpose?

There are many types and designs of floor tiles. Manufacturers of rectified tiles offer a wide variety of patterns. Which type is best for tiling a floor without grouting?

Before starting to tile the floor, you need to know how many of the elements you need. For this purpose, calculate the surface of the floor, multiplying the width and length of the room. If the area is not rectangular, just divide it into smaller rectangles and sum their surfaces. Then measure the area of one tile and divide the area of your room by area of a tile. Round out the result - it’s the approximate amount of tiles you need. You should increase it by 10% to have spare elements for cuts and in case of damage.
