Perfect grouts - how do you choose them, and how do you apply them?

Perfect grouts - how do you choose them, and how do you apply them?

When arranging a bathroom, elements such as the grouting are often treated with less attention than the tiles or ceramics. It is a pity, because it is these seemingly minor things that make the interior a coherent whole. But how do you choose the perfect grout? And how do you apply it later? These questions are answered by a Cersanit expert.

 Once you know exactly what the bathroom of your dreams should look like - you have chosen the colours, materials, textures and forms - it is time for details, including choosing the grouts. Contrary to appearances, their selection is not as difficult as it might seem. There are three aspects to consider.


The main issue when searching for the perfect grout is its colour. And here there are two alternative options to choose from.

You can choose a shade that perfectly matches the tiles (in the case of multi-coloured collections, the dominant colour) to obtain the effect of uniform wall and floor surfaces. With this, the bathroom will acquire a subdued, calm and harmonious look. Just perfect for resting.

Alternatively, you can also choose a contrasting look by combining black with white, grey with yellow, etc. In this case each tile will be clearly marked, and the whole composition will gain a dynamic, modern character. In such a bathroom, it will not be difficult to gain energy for the whole day.


What about the joint width? Here, you have to answer the question - do you want to emphasise the grout or blend it into the background? If you want a subdued interior - let the joint be narrow - the minimum recommended width is 3 mm. If you want the grout to play a decorative function - make the joint wider - about 7 mm.

Wider joints are also suitable for tiles or facings with irregular edges. In addition, they are recommended in places where they are exposed to considerable temperature differences, e.g. on terraces or balconies.


The last, but certainly not the least, important issue is the joint quality. There is no room for compromise here, because nothing disturbs the interior like grout that is crumbling or difficult to clean.

Check whether the grout can be used in places exposed to moisture and water. Not all products available on the market will work in shower cabins.

Stronger joints should also be used in heavily used interiors, e.g. hallways and corridors. In such places, it will be exposed to rapid soiling, so use a grey colour instead of white.

The 3 rules

When choosing the grout colour, remember the universal principle - mosaics look best with neutrally coloured grouts - preferably in shades of broken white. They will highlight the beauty of small tiles. In turn, with large-size collections, especially those inspired by stone or industrial materials, try to make the grout colour as close as possible to the colour of the tiles. This will guarantee a great homogeneous effect.

Do not be afraid to use different shades of grout. If you choose a collection of tiles with vivid colours, e.g. GRAVITY, which combines the power of fashionable pomegranate and the delicacy of classic white, you can use two appropriately matched grouts. This will allow the designation of separate spaces in the bathroom, e.g. bathing and toilet areas.

If you are not sure what the entire bathroom will look like - apply the grout on a small area and let it dry. You will be able to see its final colour and evaluate the effect. If you are not satisfied - just remove the grout and apply a new one.

How do you apply grout?

How do you apply grout?

Although it is most convenient to leave the grouting to specialists, it is worthwhile trying to apply it yourself. To make proper joints, all you need is some knowledge and practice. You will need a spatula, a rubber float (metal can scratch the tiles), a special sponge and a bucket to mix the grout. Apply the grout at least one day after laying the tiles so that the mortar is dry. Before you start, remove the remaining spacers and clean the surface thoroughly. Mix powdered grout with cold water to obtain a smooth and quite thick texture. Note the proportions indicated on the packaging - too thin or too thick and it will not fill the joints properly. Apply the grout using circular movements - so that each gap between the tiles is filled from different directions and at various angles. By doing this, you will avoid unsightly cavities. You should take care not to leave excess amounts of material on the tiles - this will make cleaning easier. After about 20-30 minutes (no longer, because solidified grout is hard to wash off) wash the tiles with a wet sponge. In this way, you will not only clean them, but also smooth out the joints. The last step is to secure the joints with a special impregnating preparation that will increase their strength and resistance to moisture.
