Rating of the best porcelain stoneware adhesives for 2025

Installation of porcelain stoneware is a rather complicated process, which is primarily due to the characteristics of this material. Porcelain stoneware absorbs moisture very little, which forces the user to use special elastic adhesives in order to ensure normal adhesion to the substrate, because. with ordinary cement, this cannot be achieved in any way.

Features of the use of glue for porcelain stoneware for exterior and interior decoration

If it is planned to install tiles of the type in question on the street, then you will have to use special glue for external work. The external environment is quite aggressive, due to constant temperature fluctuations, the possibility of precipitation, exposure to wind and sunlight. It is also worth remembering about various kinds of mechanical influences. Accordingly, porcelain stoneware is perfect for such conditions as a very strong material, but the glue for it must be special, capable of firmly gluing the tile to the surface, while counteracting aggressive external conditions.

It is also worth taking into account the features of the place where the cladding will be carried out. Concrete base, plinth or porch - any of them requires a special approach, and therefore a special composition of the adhesive. For the porch, water-repellent substances will be preferable, for the base - they are the same, but with increased fixation strength. For a concrete base, almost any adhesive composition for external work is suitable. When decorating a veranda, loggia or balcony, special options will also be required, because these objects, although located partially outside, are tightly adjacent to the interior, which means a higher temperature in them.In this case, it would be appropriate to use a substance with high resistance to frost and moisture.

With interior decoration, things are somewhat simpler - it is not burdened by the presence of a large number of difficulties. However, here, too, the choice of adhesive will depend on the installation location of porcelain stoneware elements. For example, in the bathroom you will need to use a moisture-resistant elastic adhesive. Among other things, it will be necessary to supplement the finish by filling the joints with waterproof grouts. For bathrooms, fungicidal compounds that can successfully resist mold and mildew are perfect. For flooring, plasticizers will be the best solution, making the adhesive mass more elastic. For walls, it is necessary to use substances with a high degree of fixation, capable of withstanding high tensile loads, which will create a porcelain stoneware element.

Features of calculating the adhesive layer for porcelain tiles

The golden rule of the master tiler says: reliable fixation is ensured by the following formula - the thickness of the mortar layer should be close to the thickness of the tile. However, for porcelain stoneware material, the width and length of the tile should also be taken into account, because due to these parameters its weight increases. So, for smaller samples, it is quite possible to use even universal adhesives - they will be able to support the tiled element both on the wall and on the floor. But if porcelain stoneware tiles are large, for example, 300x300 millimeters, then in this case the use of special glue will be a 100% necessity. Starting from similar sizes, only a special reinforced adhesive substance should be used.

Technical requirements for porcelain tile adhesive

In terms of its properties, porcelain stoneware can be compared with ceramic tiles or natural stone, and the former may turn out to be the weakest replacement for it. Porcelain stoneware is distinguished by its uniqueness, variety of colors, resistance to various negative influences, strength and low moisture permeability. The main requirements for the adhesive composition for porcelain stoneware material can be called:

1. The level of moisture absorption - it should be minimal, which is explained by the very dense structure of the material in question, i.e. it itself should remain exactly in the volume that was applied, while increasing the degree of general adhesion with the attached substrate.
2. The rigidity of the material - porcelain stoneware is not able to bend at all, however, when exposed to high temperatures, its fragility increases and it becomes weakly resistant to various kinds of loads. Accordingly, the adhesive must also withstand high and low temperatures, be flexible and able to withstand a considerable load that can appear between the tile and the base of the attachment. This factor will be especially important when it comes to the installation of a "warm floor" type system.
3. Resistance to the manifestation of external factors - you should always rely on what conditions the adhesive base will withstand. Usually, for outdoor work, a certain number of exposure cycles is provided for the composition. For example, outdoor porcelain tile adhesive should normally survive at least 50 seasons.

Functional classification

According to their functionality, porcelain stoneware adhesive can be divided into the following types:

• For exterior decoration - frost-resistant compositions are very suitable for such work.Minus temperatures and moisture can cause the adhesive substance to peel off from porcelain stoneware if it does not contain special additives. Such additives should not allow the adhesive layer to deform, should ensure the strength of the applied seam, and also promote accelerated adhesion of all components.
• For interior decoration - such adhesives are somewhat cheap due to the fact that they do not include special amplifiers and they are mostly used for ceramics. For interior decoration, in which the temperature regime often changes and humidity decreases / increases, such compositions are not much preferred. Traditionally, with their help, porcelain stoneware can only be laid on brick or concrete. According to the technical standards adopted in Europe, it is better to use an adhesive base of at least “C1” class for these works.
• Universal - such adhesives are often called a marketing ploy by manufacturers. If you apply them on porcelain stoneware, then first of all you need to pay attention to the class. Often, manufacturers (no hesitation) can simultaneously call ordinary substances of the class “C0” or “C1” “universal”, but these are fundamentally different compositions.
• Moisture resistant - they are used for finishing pools, shower areas, saunas, bathrooms and bathrooms. The composition of such a product contains a special additive, which is able to increase the hydrophobicity of the base (i.e., the ability to repel moisture), which is why the tiles laid on such a composition do not require additional sealing of the joints. It is worth noting that all substances that have a class above “C1” are considered to be such substances. However, it must be remembered that a moisture-resistant adhesive base will never replace waterproofing where it is really needed.
• Reinforced - another marketing technique. A similar designation can also be seen on fundamentally different cement compositions with classes "C0" and "C1". However, although the concept of “reinforcement” is not regulated at the regulatory level, this quality can be achieved in the adhesive by introducing special additives into the substance, which will provide a greater degree of adhesion, and also successfully resist the effect on “stretching”. Usually, such additives are used only in compositions of class "C1" and higher.
• Fast-hardening - these substances are able to very quickly fix the tile to the base. They resist moisture well, can provide instant adhesion, and are poorly susceptible to temperature changes. However, it is always worth remembering that the complexity of the surface to a greater extent determines the quality of grip. From this it is clear that the more complex the surface (glass, metal, plastic or drywall), the higher the adhesive index should be (from 1 Megapascal). For standard surfaces - gas block, brick or concrete - an indicator of 0.5 megapascals will suffice.

Composition classification

Depending on the constituent components, all adhesives for porcelain stoneware are usually divided into four main groups:

1. Cement - they are very affordable in terms of their cost. This is due to the availability of cement as an adhesive base. Also, in such compositions, polymeric additives are often present, which ensure the elasticity of the entire substance, and sand. As a result, many components give out such properties that cement glue is famous for - a high level of adhesion, moisture resistance and elasticity. The process of preparing the solution is very simple - just pour the base, pour water and mix.Nevertheless, such ease of preparation has a significant disadvantage - the glue will have to be applied very quickly, because it hardens almost instantly.
2. Epoxy - they are recommended for use with facing materials on a smooth base. Most often they are a two-component composition, which, in addition to epoxy resin, also includes a catalyst. The method of preparation is standard and fully described in the instructions for use. Characterized by durability and strength, excellent resistance to shrinkage. The disadvantages are the relative high cost and the inability to use at low temperatures.
3. Dispersion - there are no solvents in their composition, they are a paste-like reinforced mass, which makes the adhesion strength of porcelain stoneware to the base quite reliable. Dispersion options are sold immediately ready-made, they do not require additional preparation. Such options are considered the most optimal for both outdoor and indoor work. Their increased tenacity and strength allow excellent support of porcelain tiles. They differ in economical consumption, but their price may seem overpriced.
4. Polyurethane - these substances are the most diverse in terms of the number of substances included in them. The mixture can be either single-component or multi-component. They have a special resistance to elevated temperatures, moisture penetration, chemical attack, which will perfectly protect porcelain stoneware from destruction. They can be used for installation of "warm floor" and in places subject to strong vibration manifestations.

Porcelain stoneware installation tips

Porcelain tiles can be glued from any place, but it is still recommended to lay solid elements rather than trimmed ones.Lines must be drawn to distinguish where they intersect. The surface must be primed before gluing. If preparation has been made in the form of delimiting lines, then gluing must be started from the nearest intersection. If fast drying adhesive is used, then the maximum amount that can be mixed before starting work should cover at least one square meter of tiles. This is done in order to avoid rapid drying of the unused mixture. Also, upon completion of laying, it is desirable to level the resulting seams with a common surface. At the same time, you can cut the tile, removing its excess.

Glue consumption

Most manufacturers indicate approximate consumption rates directly in the instructions for the composition or on the packaging.

IMPORTANT! It is always worth remembering that the indicators indicated by the manufacturer are very average!

Adhesive consumption will depend on a number of essential conditions, such as:

• Type of glue - there are liquid and thick samples, which differ in the degree of consumption. For cement variations, when diluted with water, the consumption can be from one to two kilograms per square meter, which is quite economical.
• The type of tile - porcelain stoneware absorbs the composition the least, glazed tiles can absorb a little more, and the cotto type tile will become the leader in absorbing glue.
• The laying surface - ideally it should be clean and even, then it does not require a lot of glue. However, the more the surface will have pores, the more adhesive substance will be needed for it, because the degree of absorption of the base will increase.
• Weather conditions - the optimal working temperature for laying is considered to be in the region from +18 to +25 degrees Celsius.If the temperature exceeds this indicator, then you will have to make a little more mixture, since moisture will evaporate faster (for aqueous solutions). Temperatures below zero degrees should not be considered at all - at them the adhesive loses its adhesive properties.
• The skill of the installer - experience is more important here, the laying technology used, the spatula used, the thickness of the applied layer. All these parameters have a strong influence on consumption.

Difficulties of choice

Before buying glue for porcelain stoneware, you need to pay attention to the following important points:

• Classic “C0” class tile adhesive is absolutely not suitable for this material;
• The larger the format of the tile, the greater the adhesion index the solution should have;
• If it is planned to lay and operate porcelain stoneware in difficult weather conditions, then the solution must be of class "C1" or higher;
• Universal adhesive is not a universal solution for porcelain stoneware;
• Fast curing compounds must also be applied quickly.

Instead of an epilogue

A review of the market of the materials under consideration found that, for the most part, it is dominated by brands from a foreign manufacturer, or products manufactured in the Russian Federation under a foreign license. The Russian manufacturer is poorly represented, but its products are the most adequate in terms of price-quality ratio. Professionals recommend purchasing adhesives only in trusted online stores, and preferably in retail chains, in order to be able to quickly contact the seller in case of claims regarding the quality of the goods.
