The situation is more complicated with a photographic plate or a mosaic tile. In this case, you need to select the basic colors that match the tone to the panel, and select the optimal color gamut by trial and error. In addition, it should be remembered that when dried, the solution may slightly change the tone. For the rest of the cases, you can use the classic solution - the darkest color of the tiles in the bathroom is determined and the grout color is chosen for the lighter tone. But in any case not one tone with him or even darker.

In any case, consult the seller as a consultant. There are many details when choosing a color, as in the bathroom with high humidity, the color of some solutions may change.

Application

How is grouting done? Consider the steps of applying grout on a cement base.

Start the process of trowelling can not be earlier than a day after the completion of the installation of tiles.

Before applying the mixture, preparatory work is required - the joints are carefully cleaned from the remnants of tile adhesive and dust.

Materials and tools:

  • capacity for powder dilution (mixture preparation);
  • the groin itself;
  • rubber spatula;
  • sponge.

Carefully study the instructions for preparing the mixture on the package. After this, in accordance with the instructions dilute the mixture, observing the proportions of water and mixture. Make a short pause, so that the solution has acquired the necessary properties, and all its components are activated.

Then mix thoroughly. Now proceed to the direct application of the solution in the seam. The process itself requires a little skill, but at the same time you should not rush and thickly cover the seams.

Applying a small amount to the rubber spatula and making reciprocating movements, the mixture is pressed into the seams. After application, it takes about an hour to partially solidify the mixture.

Next, rinse the remainder of the solution near the seams of the tile with a wet sponge. It is important to do this in a circular motion, in no case do not rub. If flushing or holes are found during flushing, fill them with a solution of the newly prepared grout with a rubber spatula.

The next day, remove the stains and the remaining stains with a dry cloth. This concludes the work. And now you can admire the beautiful view of the tiles in the bathroom and the neat seams.
