Apartment repair often turns into an endless struggle for people, during which a lot of effort, financial resources and, most importantly, time is spent. Therefore, many prefer to update the look of their apartment with cosmetic repairs. The most demanding room is a bathroom, as even qualitatively made repairs quickly lose their original shine under the influence of moisture. Almost all people try to finish the bathroom with tiles, because this material can withstand the negative effects of moisture for many years. The appearance of even expensive tiles can spoil the grout, which eventually darkens, turns black, it creates chips and cracks. Therefore, the question of replacing the grout is relevant for many owners.
Replacement of the grout is most often necessary for the following reasons:
- does not fill the entire depth of the seams when applied. As a result, air spaces are formed, which destroy the grout;
- use of the wrong type of grouting: for the bathroom, you must choose a moisture-repellent and moisture-resistant grout, because it is due to water ingress and material is destroyed;
- use of aggressive cleaning products: when washing tiles in the bathroom, sometimes, strong chemicals are used, which destroy not only dirt, but also grout, and also erase the outer covering of the tile. Therefore, in order to prevent negative effects on the tiles and seams, you need to more carefully choose cleaning agents. The main thing to remember - expensive - is not always the best.
When should the grout be removed?
After two to three years of fresh repair, grouting, if the work was done poorly, begins to darken, to the point that it takes on a practically black shade. This happens due to the fact that in the grout formed microcracks, and sometimes large cracks, which gets moisture. Under the influence of moisture begins to form a mold that looks like black spots. Do not wait for the appearance of mold, because if you do not take measures to remove it in time, the process of tile destruction will begin. The moment you noticed that the grout between the tiles had lost its integrity, or changed its shade a little: it started to turn black, it's worthwhile to think about replacing the grout so that the negative consequences do not come.
Although it is very easy to remove the grout, there are often problems: if the wrong method is chosen, you can destroy the tile, the replacement of which can cost a round sum. Therefore, use only proven methods for removing grout from tile joints.

Prepare a drill: the drill must be a diameter with a width of the seam, so as not to damage the edges of the tile. In addition, it is necessary to use the tool only at low speeds and firmly pressing the drill to the seam, so that during work it does not fly off and damage the appearance of the tile.
If the farm does not have a drill, then you can use any metal object that you can hook on a part of the grout. There are only two requirements for tool selection: it should be less sharp( thin), and also oblong form. Removal occurs by translational movements up and down.
. Similar work can also be done with the help of a Bulgarian. Naturally, the diameter of the disk, zholzhen match the intertice seam.
