Tile glue for warm floors – how to choose, rating in February 2025

Have you had enough of the chilly winter months and cold floors? To keep your toes nice and toasty, have you thought about adding underfloor heating to your house? If so, you’ve undoubtedly heard how important it is to select the proper tile adhesive for your heated floors. We’ll walk you through every step of choosing the ideal tile adhesive for your underfloor heating system in this post, which also includes a ranking of the best choices as of February 2024.

Your home’s warmth and comfort can be completely transformed with underfloor heating, but it’s crucial to get all the details right from the beginning. The kind of adhesive you use to hold your tiles in place is one important consideration. In addition to guaranteeing a solid bond between your tiles and the subfloor, the appropriate tile glue is essential to the performance and efficiency of your underfloor heating system.

It can be confusing to choose the best tile adhesive for heated floors because there are so many options on the market. There are a number of factors to consider, including compatibility with your heating system, application ease, drying time, and long-term durability. But do not worry! Our goal is to streamline the procedure and support you in coming to a well-informed choice.

Knowing the various tile adhesives and whether they are appropriate for underfloor heating is essential, regardless of whether you are an experienced do-it-yourselfer or are hiring a professional installer. Every product has advantages and disadvantages, ranging from conventional cement-based adhesives to sophisticated flexible polymer formulations. Finding the best fit for your unique requirements and preferences can be achieved by analyzing the benefits and drawbacks of each choice.

Let"s get acquainted with the types of glue

Choosing the appropriate glue can be a challenging task for the buyer in most situations, particularly if they lack experience repairing warm floors. The primary active component of the compositions is typically used to categorize them. They fall into the following categories:

• Polymer synthetic view with one main component – resin. Glue has the shape of a pasta that is sold in a plastic bucket. It is most suitable if the master conducting the procedure does not have the appropriate previous experience, t.To. hardening occurs within 20-25 minutes after application. This time allows you to eliminate the minimum errors and get rid of the irregularities of the surface;
• Polymer – with two different resins. A similar two -component product hards very quickly, so it must be used immediately after cooking, when all preparatory stages have already been carried out. An important advantage is increased plasticity and adhesiveness, which leads to resistance to a sharp change in temperature and operation of operation even when laying the material on a complex base;
• cement mortar consisting of fine particles. Despite the large selection of polymer funds, this option remains the most popular. Due to the presence of additional modifying substances, adhesion of the product increases. The key advantage is the possibility of calculating the exact dosage of the product so that it is enough for exactly one application, this will allow the use of 1 package several times.

The primary component providing heat resistance is an additive plasticizer. These materials preserve the adhesive qualities of the glue even when the temperature changes, allowing it to shrink and widen.

Selecting the ideal glue for different sexes can be challenging because each of the aforementioned species has unique traits, benefits, and drawbacks.

It’s critical to understand! It is important to remember that, unlike choosing glue for walls, the degree of facing material is not a determining factor when choosing tile glue for heated floors. There are a few more traits that you should be aware of.

What parameters do we pay attention to when choosing

Owing to the challenging operating conditions, specific requirements are placed on the adhesive composition for the porcelain border on the heated floor. Prior to purchasing, you should educate yourself on the following crucial factors:

• Temperature drops. As a rule, glue for warm floors and directly porcelain tiles have various expansion coefficients. This parameter suggests that with a decrease or increase in temperature, the adhesive mass will narrow and expand. With low stability on the adhesive surface, microcracks will form, which will ultimately lead to separation and damage to the tile cladding. It is important to choose a mixture with high elasticity, but even at the same time it will be necessary to additionally provide a strong connection in the areas of damper seams.
• The degree of adhesion of glue with the surface. In most cases, cement species cannot provide sufficient adhesion with tiles, so it is advisable to choose polymer species or cement, but with the addition of a large number of plasticizers. They allow you to increase adhesion with smooth artificial stone.

• Strength. As noted earlier, the severity of the tile is not of such important value as when laying tiles on the walls (due to the power of attraction), but it should still be considered, especially if glue is chosen for porcelain tiles. Make sure before buying that the glue composition is able to withstand an increased and multidirectional load. Otherwise, it will fall apart in the first year of operation.
• Time until completely solidified. It is necessary to select an option, the adjustment time of which is up to 2 hours, and a possible period of position correction is at least 15 minutes. This will avoid ineffective waste of expensive material, especially if work is carried out with such a complex coating as porcelain stoneware. This will also ensure the correct arrangement of tile cladding, which will improve the quality of repair work.

Which tile adhesive works best on heated floors? the one for which each of the aforementioned parameters has the highest values.

Producer rating

There are currently numerous producers of floor tile adhesive available on the market, including Ceresit (Ceresit), Bergauf, and T.D. Their differences extend beyond composition and application style to include domain of operation.

While some types are widely used, others are only appropriate for specific warm floors and tiles.

Ceresit

The most common imported choice for a warm floor is cerezsite glue. Although it was produced in Germany, Russian consumers gave it widespread recognition. Because of its enhanced elasticity, it can be applied to a variety of warm flooring types and finishing materials.

Cerezit works best with ceramic tiles, such as porcelain tiles (select models SM No. 14, 16, 17 or 117). Marble tile glue is also widely used (see 115).

The benefit of ceresitis is the warm floor in the best German quality, ensuring that it can continue to function in the future.

Its production using only safe and environmentally friendly materials is another benefit. Even with a significant rise in temperature, the generated tile mixture does not release any dangerous substances or endanger the environment or human health.

But it’s crucial to pay close attention to the labels on the packaging and in the instructions that are attached. If the mixture is labeled as being only appropriate for concrete, it cannot be applied to other surfaces, such as wood, plastic, or metal.

What you should know about the 14 Extra’s floor tile:

• survivability – 2 hours (time before hardening);
• The master can adjust the placement of tiles for 15 minutes. after the initial application;
• In the implementation of repair work, the air temperature should be 5-30 degrees of heat by Celsius;
• It is allowed to wipe the seams no earlier than a day after installation;
• The degree of adhesiveness is 0.8 MPa;
• The created coating with Ceresit glue for a warm floor can be operated at a temperature of -30 to +70 degrees.

Bergauf

This German-Rosia company produces Keramik Express glue. Its unique benefit is the mixture dries quickly; 4 hours after they are finished laying, you can already walk on the tile.

This shortens the amount of time needed to wait for the seams to grout as well as the amount of time that the material’s position may be corrected. For masters who have prior experience in related fields, it is advised.

Things to be aware of regarding this tile adhesive for heated floors:

• The survivability of the diluted mixture – 45 minutes.;
• The one -time coating should be no more than 0.6-0.8 m 2;
• It is allowed to change the position of the material only for 10 minutes;
• It is allowed to grout the damper seams after 4 hours;
• The temperature during operation should be from -10 to +70 degrees.

The ideal tile mixture is one that won’t deteriorate when installed on a sturdy substrate, like concrete.

Knauf

This brand offers a large selection of floor adhesives, but a specific mixture called Knauf flex is required for warm floors. For styling on a complicated base (gypsum accommodation or old tile), this tile glue works wonderfully.

Top-notch characteristics include superior waterproofing and high elasticity and adhesion capacity indicators (1 MPa).

The prepared solution has a three-hour use window and requires ten minutes for correction. Temperatures between -30 and +80 degrees are acceptable for operation and between 5 and 25 degrees for installation. After styling work, the resulting seams may only be rubbed for three days.

What’s crucial to understand is:

1. Prior to laying tiles, the warm floor should warm up at least once 1 time, and then cool down for a day;
2. If the air temperature in the room when installing tiles on a warm floor below 10 degrees, you need to turn on heating to 15 degrees;
3. Prior to the placement of electric heating mats, it is necessary to primer the base with a special mixture of the same brand;
4. With increased moisture content, the surface must be covered with Knauf Flachendicht.

Litokol

This manufacturer (model K80) produces a cement mixture for heating floors that is used in homes. Work begins with the preparation of the dry mixture. The qualities of tile glue for a heated floor are as follows:

1. Survivability – 20 minutes;
2. The adjustment period is 1 hour, which is one of the highest values compared to analogues;
3. The temperature of the room when laying 5-40 degrees;
4. Operation is allowed at a temperature range of -30 to +90 degrees;
5. Walling seams is possible in a day.

This manufacturer provides a Litoelastic gluing mixture in the event that polymer tile glue was chosen for the flooring. After kneading, it must be used within 45 minutes, and an additional 45 minutes are allotted for potential situational adjustments.

Unis

Glue for the "Unis" tiles made in the country, though not less excellent than European cerezitis. The majority of items on the market are versatile and fit for any type of coating.

The benefit of using this mixture for tiles is that it is completely safe for the environment, so you can even use it to finish the warm floor in the kids’ room. Increased adhesion (1.2 MPa) is an additional benefit.

Qualities of the warm floor adhesive unit:

• The viability of the finished adhesive solution is 180 minutes.;
• the period until the applied composition to the tiles is dried – 20 minutes.;
• The period of possible correction is 10 minutes.;
• grout of damper seams – in a day;
• Operation at a temperature of -50 to +70 degrees is possible.

Such glue is not necessary for a deformed base.

Prospectors

The adhesive for tiles called "Prospectors Plus" is made in Russia and is intended for floor installation. Its application is limited to surfaces that are not prone to deformation.

After the solution, the manufactured composition can be used for four hours, and only fifteen minutes are allowed to adjust the tile positions. For the majority of tile coating types, the adhesion value of 0.5 MPa is sufficient.

Emple

The Russian brand, "Maximiplik T-16," is designed especially for warm sexes. It can be identified by a longer dating time (4 hours). Editing time: fifteen minutes. Ideal for straightforward coatings (like cement screed).

Choose the best glue for tiles

The features of the room (the capacity to maintain the required temperature during installation and operation), the complexity of the flooring (concrete screed is the most basic, and old tile or gypsum glue is the most time-consuming), and the type of warm floor system must all be considered when selecting the appropriate tile glue for porcelain tiles on a heated floor.

Ceresitis works great for the water floor and is suitable even for inexperienced coating installers. It is recommended to use either Bergauf (if you intend to create a screed) or Knauf (if an additional screed is not created) for an electric design.

If you have to go with a less expensive option, research Russian brands. For instance, the glue "prospectors" is more elastic and reasonably priced at the same time.

Laying instructions

You must get ready the following tools for work:

1. Construction spatula with teeth;
2. Glue (suitable for the system of warm floors);
3. Bucket, trowel, brush;
4. A means for deep priming (it should be compatible with the selected tile glue for a warm floor);
5. Mixer;
6. Suitable volume container for the preparation of glue for tiles;
7. Level;
8. Tile cutter;
9. Facing material;
10. Rubber hammer.

Steps involved in applying glue (such as concrete screed without deformation) to lay tiles on a warm water floor:

1. Elimination of dust and other garbage from the screed (it is best to vacuum).
2. Surface primer to improve adhesion. The mixture should be applied exclusively on a dry screed. To check this, you need to cover a certain area with a film at night, if drops appear on it in the morning, it is necessary to add the floor additionally. The primer should completely cover the surface without the slightest pass.
3. Preparation of adhesive solution. It should be made strictly according to the instructions. Mix all the ingredients with a mixer, add water at the end.
4. Preparation of tiles. To increase adhesion, a primer of the inside of the future coating is allowed.
5. Apply glue for a warm floor on a screed, to align the layer, you must use a spatula. It is not required to cover a large section at once, it is better to lay out the mixture gradually.
6. Apply the mixture to the tile (the thickness should be minimal – up to 0.5 cm).
7. Put the tiles, preserving equal gaps between them, using plastic crosses (they can be removed after 2 hours).
8. Когда плиточный клей для теплого пола полностью высох, провести затирку швов.
