Mosaic tile adhesive: selection criteria

If you have opted for mosaic tiles for decorative wall coverings in the bathroom, kitchen apron and other surfaces, then first you need to decide on the choice of glue for this material. Currently, there is a large assortment of different types of solutions for various surfaces..

In order to choose the glue you need, you need to know: on what basis we will fix the products, the composition of the tile itself, the conditions of its operation.

If you choose the right material, then the finish will last a long time without the necessary restoration..

Choosing a mosaic mix by its type

There are three types of tiles:

  • glass;
  • ceramic;
  • stone.

Glass mosaic solution

For this texture, the color of the mixture is important.. For transparent and translucent tiles, white glue is required.. The base to which it is attached is translucent and if you use a gray unsightly solution, then its appearance will be far from perfect.

For opaque mosaics, color is not important. This type of tile is well suited for a white cement mortar, you can use dispersion or reactive epoxy or polyurethane based.

Mix for ceramic mosaic

Mosaic ceramic tiles are the most unpretentious; any cement-based glue with a gray or white color component is suitable for it. In this case, an important criterion for choosing the composition of the solution is the surface on which it will be applied.. The substrate must have excellent absorbency. If everything meets the requirements, then we choose the standard option – cement mortar. With such glue, the base will adhere well.

One of its advantages is its low cost.. But if the surface has poor absorbency, it is necessary to choose an elastic solution with increased adhesion..

These compounds are more expensive in price, but will reliably hold ceramics on a problematic substrate..

Stone Mosaic Adhesive

For such a tile, the choice of color is not important, but the properties of the stone used are taken into account. For some products, it is undesirable to use water-based solutions, it is worth preferring quick-hardening cement or polyurethane – it does not contain liquid. In other cases, the choice of the mixture is made depending on the surface properties, as well as for ceramic mosaics..

The choice of the mixture according to the conditions of its operation

If the mosaic will be used in swimming pools, other rooms with high humidity or direct contact with water, then you will need mixtures with special additives.

Pool solution must have:

  • the ability to absorb moisture;
  • increased elasticity, which ensures reliable fixation of the product with the base.

In such operating conditions, water-resistant types of glue with high adhesion rates are used for glass elements. With adhesion of at least 2.5 MPa, fastening the waterproofing of the object with glass will guarantee the durable use of the finish. Solutions that include plasticizers – liquid latex are considered even more durable. Polyurethane or epoxy compounds can cope well with this task, but at a price they are much higher.

There are other solutions that are used in various atypical situations.. If you urgently need to cover tiles for a warm floor, use fast-hardening glue or special solutions. Always when buying, you need to carefully study the instructions on the packaging or consult with a specialist. It is necessary to know all the features of the use of solutions: for what bases they are intended, types of mosaics, possible operating conditions of the surface.

Work on objects with high humidity should not take place at an air temperature of less than 5 degrees Celsius. Adhesive mixtures in such conditions lose their characteristics..

The choice of glue according to its composition

According to the content of the components, three types of solutions are distinguished: with a cement base, dispersion and reactive mixtures. Each of these compounds has some characteristics and advantages over each other. But the main thing for everyone is quality. Under various conditions of use, even the cheapest material, they can be very reliable..

Cement composition

The composition of the glue is normal, any mosaic can be placed on it, except for transparent glass tiles. The mixture is produced in the form of a white or gray powder and, according to the instructions for use, is diluted with clean water. If, when using the cement composition under the mosaic, it will not be very noticeable, then a dark color can also be used..

Latex should be added to the mixture when increased elasticity of the adhesive is required.. And if such a need does not exist, it is quite appropriate to use it for fixing the mosaic. The cement composition is distinguished by its low price..

Initially, various mortars based on a cement mixture are able to withstand high humidity, vibrations, as well as large temperature fluctuations in the places of lining. The adhesive can be used for work outside the building and inside, for example, for underfloor heating.

Dispersion composition

A very unpretentious one-component solution to use. To use it, you do not need to mix or carry out any work on its preparation. Remaining glue can be stored in a tightly closed container until the next use.. These water-impermeable solutions are good for work in rooms with high levels of humidity..

The consumption of the product is small, which gives it an advantage over the cement mixture, despite the higher price.

Reactive composition

This adhesive has a two-component composition, which consists of a hardener and a base. They mix with each other and, due to a chemical reaction, form a high-quality sticky mass. The mortar is made from epoxy or polyurethane resins. Reactive composition best suited for use in harsh environments with high humidity, high temperature fluctuations and vibration, as it has high plasticity.

For large tiles on a special mesh, glass mosaic and marble, you must choose a waterproof adhesive.
