The masonry of ceramic tiles can be different, so the seams can be either relatively wide or narrow. To properly do the job of grouting seams on the joints of tiles, you need to understand why and how to seam the seams and how it can be done.
Why is grouting
First, to ensure the waterproofness of the entire surface. After all, the tiles are laid out the surface in rooms where the constant high humidity or often consumes water. Therefore, splashes, evaporation, etc. And if the floor tile, the floors because they regularly wash. Consequently, under the tile coating will penetrate the water.
Secondly, there are no tiles ideally square or rectangular, hence - the slits at the joints will in any case.
Thirdly, the tiles can not be laid "back to back" to each other. There is such a thing - temperature expansion. Dense packing can lead to deformation of the surface and, as a result, "swelling" of the entire "masonry".
Which "grout" to use
First of all, it is necessary to understand the difference between trowel and sealant( sealant).For seams, the grout is used. There are two types, and the difference in the basis: it is either cement( with additives), or epoxy. In everyday life it is better to use grout on a cement basis. They are easier to work with, and they are cheaper.
As grout to prepare
The manufacturer's recommendation should be studied without fail. Different composition requires its own methodology. It is better to buy the formulation in dry form, it is much cheaper. It is necessary to find out what to breed: water or latex( liquid).Dry polymer compounds are mixed only with water!
Stages of work:
- Preparation of grouting. In addition to the already mentioned, it should be borne in mind that the kneading should be done carefully, not allowing air bubbles to enter into the air bubbles. It will only weaken the action of the solution;
- Laying out the solution. Using a grater, the solution is literally pressed into the seam, evenly distributed along the entire length. The hand makes diagonal movements. The task is to fill the voids as much as possible. It is more convenient to work in a small area, and not immediately along the entire wall;
- Wet surface cleaning. It is produced after sufficient solidification of the mixture;
- Align and smooth joints. It is made by specially made screed.
If you want to get an imitation of the old masonry, additional measures are taken.
