Features laying mosaic with mirror surfaces.
Quite a lot of modern mosaic comes with the inclusion of mirror chips, which can be either pure pieces of a classical mirror, or stylized for various textures such as "wrinkled foil", "sparkles", "crystals", etc.
To create a beautiful mirror effect of the matrix and a different tint of mosaic, manufacturers use a fairly wide range of technologies and chemical additives to the compositions of mirror amalgam. In this regard, the question arises of preserving the original appearance of the mosaic in the process of pasting and its subsequent operation. Since manufacturers keep the exact composition of the mirror inserts in the strictest secrecy, and at the same time the manufacturers of adhesives and groutings are also not in a hurry to reveal their secrets, it is naturally quite difficult to predict how this mosaic may change in the course of work.

Some advice on the use of mosaic with mirror surfaces in everyday life.
  1. Eliminate the use of mirror mosaic in the bowls of the pools and interiors of wet rooms (baths, saunas, pools, fountains). In general, those rooms where a stream of water can pour on the surface of the mosaic.
  2. Be careful about adhering to the technology of glue and grouting with water. Excessive water content in the solution leads to the penetration of moisture into the amalgam composition and the beginning of a chemical reaction with it, which can impair the appearance of the mosaic (mainly the blackening of the chip).
  3. Before carrying out the work it is desirable to conduct a test for chemical compatibility. You can take a small piece of mirror mosaic and apply the prepared glue and grout on its back side. If the reaction is manifested, then you will spoil everything, only a small piece of the matrix, and not the entire volume of the material.
  4. Use anhydrous compounds as adhesives. A number of manufacturers have glue and epoxy based grout. With almost 100% certainty, these adhesives will not cause an undesirable chemical reaction in the structure of amalgam mosaic, and, moreover, will reliably isolate it and attach it to the surface from practically any material. Based on our experience, I can advise you to use the colorless grout MAPEI Kerapoxy Desing at number 700 as an adhesive. Of course, there are also disadvantages of these adhesives - this is their price, strict adherence to technology and proportions in the production of works, and some experience with such compositions, but the properties of these grout are so high that they more than cover these disadvantages.
