The right choice of adhesive composition for tiled ceramics of various rooms plays an important role in the process of their finish. An example is a special two-component elastic adhesive for ceramic tile, which is beneficial from traditional sandcate mixes with the addition of PVA.
Such composites should have a high adhesion ability, superior to other types of glue, and the ability to firmly hold on smooth, not absorbing moisture surfaces. Such materials include glass surfaces, glazed side of tiled ceramics, dense stone.
The elasticity of the mixture should be such that it can stretch without cracking, absorbing small deformations of the foundation, including temperature.
Due to the high content of the binding components, the bulk of elastic mixtures is distinguished by water resistance and frost resistance. They can be used instead of conventional adhesive compositions, which is why the quality of facing works is significantly increased. In addition, they greatly facilitate and speed up the work process in comparison with any other types of glue. Working with them, you can get an additional 5-10 minutes to adjust tile masonry.
The use of composites of the type of quartz sand, andesite or graphite, as well as various polymer plasticizers give them a large plasticity in comparison with conventional analogues.
How to choose?
The durable connection of the tile with the surface is the main requirement to all intended for this purpose, adhesive compositions. However, its execution largely depends on the degree of elasticity of the tile glue, because the probable temperature differences can give some mobility to the base on which the tile mounted. It can lead to detachment or cracking of ceramic facing. Therefore, the use of elastic adhesive composites protects the tiled layer of deformation.
When choosing between a cement-based composition and epoxy glue, preference should be given to the last due to its larger plasticity.
A large convenience of one-component pasty compositions are available on sale in fully prepared for use. They are plastic enough to extend the lifetime of the facing coating and secure it. They do not require kneading, you can work with them immediately after purchase.
Such ready glue is most suitable for interior decoration of rooms with a small area. It is used to fasten the tile facing in the bathrooms and kitchen rooms when it is necessary to maximize the amount of dust during operation.
Single-component mastic compositions on a latex basis or on the basis of other petroleum products are distinguished by increased fixing properties, very elastic and waterproof. They are easily applied to the pre-primed base with a thin layer and do not create inconvenience when working with them. Tile presses the adhesive layer, and then it is slightly closed. Excess the composition remove with alcohol, White spirit or acetone.
Cement-based formulations, which sometimes have additives from plasticizers, are cheap, quick-hardening white tile adhesives with a relatively low level of elasticity. They are based on a white cement with additives to increase the viscosity and elastic properties of the composition. Such mixtures are often used to create a mosaic.
If there are no plasticizers in this composition, it works very quickly. If, for example, there is a bucket of such adhesive, it is very likely that it will be possible to use only one fifth part of this volume.
Glue with cement at the heart
Represents the simplest type of binding solution consisting of cement and purified sand. It is mounted massive porcelain tile, natural stone or its artificial analogue and a large-format tile. High-grappling characteristics of such a composition can be significantly strengthened by adding extinguished lime to it. As a result, it will turn out a very highly elastic mixture capable of providing cladding in a horizontal and vertical plane. It can be used both for the interior decoration of rooms and for external work, for example, facade.
Besides, Operational characteristics of such a mixture, in addition to lime, can be attempted to improve the additives in it PVA, liquid glass or latex. However, it can be mistaken with proportion. Therefore, it is better to purchase a ready-made dry composition with improving ingredients already added to it.
Any adhesive composition is worst with a smooth surface. The creation of high-quality adhesion requires the impressability to be processed by glue. For such work, it is advisable to purchase glue in tubes and tubes for construction pistols. These compositions include liquid nails.
Working with these composites does not require a toothed spatulas, nor individual capacities for kneading them. Gele-shaped adhesive polymer on an acrylic basis is applied to the surface of the wall or tiles in the form of strips or droplets. His name “Liquid nails” Composition of this kind got because it creates a point connection tile with the basis. They are easy to use and ensure the gluing of the cladding tightly.
Liquid nails are a separate type of modern binding composites on an neoplative basis with additive from polymers and synthetic rubber. This type of glue refers to toxic substances, is distinguished by an unpleasant odor, and working with it should be carried out using protective equipment. Liquid nails on a water-based applied in dry rooms for small restoration work, as they do not tolerate moisture.
Dispersion adhesive mixes
Dispersion binding mixtures are pasty tiled adhesives. This form of delivery of this product completely eliminates consumer errors that are manifested when trying to independently connect the components of other types of adhesive compositions.
These mixtures consist of organic binders in the form of polymers, bitumens and various trigteral varieties. In their composition there are high-quality modifying additives and mineral fillers of natural origin in the form of quartz and silicate sand, as well as graphite and Andesitis.
For styling tiled ceramics, dispersion mixtures are excellent glue, giving the opportunity to arrange plastic, wooden and metal surfaces with a small spending of the binder composite. With it, you can update the tiled flooring of the floor and walls right along the old tiles.
The disadvantage of dispersion adhesive mixtures is the absence of the possibility of their dilution, thickening or mixing with other ingredients, as well as the long term of their frozen, which can last up to 7 days.
Epoxy binding mixes
For those situations where the tile is attached to the Faneur, CSP or a tree, the use of jet adhesives formed as a result of the reaction of two different components becomes a more rational option. This, first of all, should include the universal epoxy adhesive composite based on the resin, formed after mixing it with a hardener. From the content of the latter depends the time of setting the composition, so Do not increase the concentration of this component. Otherwise they will not even be able to lubricate the tile – he will just freeze.
Epoxy tile glue composition is not only a two-component – it can be a multicomponent binding composition consisting of several varieties of epoxy resins with additives and catalyst-hardener. Epoxy of modern varieties are also enriched with various modifying and plasticizing additives and additives from fillers and solvents.
Forms of supply of epoxy compositions are sets of a paste-like or liquid mixture and a catalyzing hardener, packaged into separate containers and kits in which resin, harvesting and filler.
As the latter, additives in the form of quartz sand, cement, alabastra, aerosyl, a variety of fibers, marble crumbs, sawdust, metal powders, microscopic hollow balls – microspheres can be applied.
The advantages of epoxy glue include its ability to reliably fix the tile coating, mechanical strength and elasticity, resistance to ultraviolet and aggressive chemicals, frost resistance and waterproof, as well as the ability to be used as a grout.
Of the disadvantages of epoxy adhesive composition, it should be noted the need to prepare it manually, high cost, sensitivity to errors in compliance with the proportions of its ingredients and the impossibility of removing this composite from the surface of ceramics after its solidification.
Epoxy adhesive has such significant grip indicators that it allows you to install tiles on a variety of foundations: wood, paneur, concrete, plastic, metal surfaces and glass.
Regarding the specifics of the use of epoxy adhesive composite, it should be noted that it is desirable to use it, given the air temperature. For example, at 25-35 ° C, the rejection of the glued surfaces occupies an average of about 5 minutes, and the rejection time is about 1 hour.
Epoxy adhesives in liquid or pasty form should be applied to the surface of the tile with a brush, spatula or spray with a gun.
The reaction between the epoxy resin and the hardener is irreversible, so the installation work using this type of glue requires some professional skills and the corresponding skill.
Epoxy composite is an ideal adhesive composition for working with glass mosaic, bright types of decorative smalt, elite ceramic coatings, elegant stone and marble types of decor.
It should be noted that whatever composition of the adhesive substance was selected, it is necessary to work with it neatly using the security tools for respiratory tract and hand. Otherwise the consequences may be unpredictable.
