The concept of grout
What is a grout to fill the space between the tiles? This is a special substance that serves to fill the seams and joints between the elements of the tile. This substance in a dry form is a powder, which turns into a paste when contacting water. Grout serves as an element of decoration and jewelry. Moreover, the grout avoids any problems with water or any other fluid under the tile, which can cause its further deformation and falling off.The grout itself is an ordinary mixture of cement with a number of additives to ensure moisture resistance. Also, the grout usually dries slower, but at the same time, plastic, sometimes resembles a chewing gum in consistency. Dilute the grout either with water or liquid latex. A seam grout layer is at least five millimeters. The grouts themselves can be classified into two large groups: grouts based on cementing materials and on the basis of tarry substances. At the same time, cement grouts can, in turn, can be divided into simply cement and cement with elements of cement sand.
Cement -based grouts
Sand grout is a grout that includes sand elements. Typically, such a grout is much stronger than an ordinary analogue, it is used where the ground seam is too large. In this case, depending on the size of the sand, the seam thickness may vary. Such grouts are usually either white or gray, besides, they do not look very good on glossy surfaces.Epoxy grout is a mixture that consists of an appropriate resin, made of pigments of a dyeing property, from a hardener, which makes the grout denser, and also does not allow it to be afraid of moisture, pollution or mechanical exposure. However, such grouts are expensive, so they are used infrequently. If they are used, then, as a rule, in retail premises, in banks. This type of grout is knitted, quite naughty in work and poorly clean it from the applied surface.Moreover, if your tiles have very small dimensions, then a situation can be created when a grout due to narrow seams simply cannot penetrate deep into a crack. Epoxy grout has an option — a grout with Portland cement. Such a grout is more like a cement analogue rather than a resinous grout. At the same time, such a grout practically does not fade, and its margin of safety is much higher. In order to make sure that you need an epoxy grout, first test it for compatibility with chemical reagents from which you plan to protect the ground surfaces. At the same time, it is extremely desirable to use the respirator in such works.
Resin -based grouts
Furannova grinding is the most durable of all types of grouts. The fact is that this resin does not contain a drop of water, which provides unsurpassed strength of the grouting even when it is processed with chemical reagents. Attention: all the tiles must first be covered with wax, and the remnants of the grout are ruthlessly removed using a jet of hot steam. Such grouts are made in black or dark colors. True, sometimes, such super -resistant grouts easily enter into a violent reaction with those acids to which the reaction of epoxy counterparts is more than moderate. Therefore, carefully test the grout before you start using it. And, finally, in addition to all the above grouts, it should be remembered that there are a lot of various modifications that will allow grouting where and anytime.
