Properties and use of two -component adhesives for ceramic tiles

Because two-component adhesives are stronger and more durable than traditional adhesives, they have completely changed the way we approach tiling projects. These adhesives are made of two distinct parts that, when combined, form a strong bond that can withstand a variety of pressures and environmental factors. This makes them the perfect option for ceramic tiles, which need a trustworthy adhesive that will hold for a long time.

Two-component adhesives primarily consist of a hardener and a resin. They react chemically when mixed together to create a strong adhesive with outstanding bonding capabilities. Strong, resilient bonds are formed as a result of this reaction, which is resistant to moisture exposure, temperature changes, and heavy foot traffic. Two-component adhesives offer the assurance that your tiles will stay securely affixed over time, making them especially well-suited for both indoor and outdoor tiling projects.

The versatility of two-component adhesives is a major benefit when it comes to ceramic tiles. They are a versatile solution for a range of installation scenarios because they can be applied to a variety of substrates, such as wood, concrete, and already-installed tiles. Furthermore, especially in high-traffic areas like kitchens and bathrooms, their quick curing time guarantees that tiled areas can be put back into use sooner, minimizing downtime and disruption.

Two-component adhesives also have the advantage of having good water and chemical resistance. This makes them the perfect option for damp spaces like kitchens, bathrooms, and swimming pools. Because of the adhesive’s resilience, tiles stay firmly bonded, avoiding problems like tile lifting and water damage that may require expensive repairs.

In conclusion, two-component adhesives provide ceramic tile installations with a dependable, long-lasting, and adaptable solution. Because of their excellent bonding qualities, short curing times, and resistance to environmental influences, they are a popular option for both professional and do-it-yourself tile projects. When working on a large-scale commercial tiling project or a small-scale bathroom renovation, two-component adhesives offer the strength and dependability required to guarantee long-lasting results.

Two -component glue – description

The high-strength composition of tile two-component glue is embodied by the hardener and polyester or epoxy resin. Additionally, binders of synthetic origin must be added to the mixture in order to improve the qualities of an adhesive seam. These consist of minerals, plasticizers, and modifiers that maximize the mass’s plasticity.

The polycondensation reaction, which starts when the two components are connected, causes the solution to solidify. They can still glue ceramics, tiles, boards, mosaics, and both natural and artificial stone. The majority of adhesives can be used with laminate, linoleum, or parquet flooring.

The piece is utilized for both internal and external tasks. A device for waterproofing high-humidity rooms is equally popular. The majority of brands are appropriate for working on deforming and vibrating surfaces in addition to tile facing. Other surfaces that two-component adhesives adhere well to are:

• concrete, brick, aerated concrete;
• cement screed;
• plaster;
• drywall, gypsum fiber, gypsumlite;
• metal;
• OSP, plywood, chipboard;
• Old tiles of walls.

Properties and characteristics

Depending on the basis, adhesive compounds with two components may differ. This is how glue can look:

• polyurethane;
• epoxy;
• epoxy-polyurethane.

Polyurethane compounds are the most elastic; they don’t crumble or crack and can retain their "rubber" qualities under all circumstances. When greater resistance to moisture and chemical action is needed, epoxy compositions should be used. Adhesives made of epoxy polyurethane are the strongest and most efficient.

Polyurethane composition

This material, which is ideal for cladding facades and interiors, is the most widely used for tile installation in both dry and wet areas. The composition contains hydroxyl-containing compounds, polyester resins, PAVA fillers, isocyanates, and composite materials as well as fillers to increase viscosity. Polyurethane, which is created when the other ingredients are mixed, is the primary active ingredient. Waterproof adhesive composition also includes the addition of aminoamides.

The characteristics of two-component polyurethane glue are as follows:

• excellent adhesion to different surfaces;
• lack of shrinkage;
• Tixotropic – the ability to recover;
• heat resistance;
• high strength of the seam;
• frost resistance;
• water resistance;
• Lack of sliding from vertical surfaces.

The mixture can be applied to high-pounding surfaces and used to glue porous products. Ceramic tiles work best with polyurethane material, which is suitable for wooden foundations. Additionally, polyurethane glue works well for heating floors—for instance, when adhering kitchen tiles.

Epoxy adhesive

Tile adhesive made of a reactive composition is called epoxid-based glue. Resistance to other chemical components, such as alkalis, and acidity are distinguishing characteristics. The epoxy is extremely resilient, waterproof, resistant to frost, doesn’t shrink, and doesn’t deteriorate over time.

Due to the high cost of these materials, installing tiles with an epoxy composition comes at a significant cost. As a result, using them at home is inappropriate, but glue is highly needed in factories, elevators, airports, and ships. Tiles on plywood, chipboard, metal, concrete, brick, and other materials can all be fixed with it.

Epoxy-polyurethane glue

Since these funds are a part of both epoxy resin and polyurethane, they have all of these compositions’ characteristics. The adhesives are very strong, elastic, and resistant to moisture, temperature fluctuations, and other environmental elements.

Pros and cons of two -component compositions

There is no denying the two-component adhesives’ high efficiency. Among the benefits are:

• the ability to glue all known materials;
• maximum discovery strength;
• the ability to use in any room regardless of environmental conditions;
• Long service life.

One drawback is that it’s very expensive, though epoxy compounds are exempt from this. The majority of adhesives have properties that deteriorate if the component mixing instructions are not strictly followed.

The difficulty of removing the glue from the tile and other materials after they have completely cured should also be taken into account as a drawback, though this is not surprising for a material with this level of strength.

Adhesive manufacturers

Construction stores carry a wide selection of two-component adhesives, and their costs are noteworthy. The compositions that are most well-known are explained below.

Litoelastic

The adhesive Litoelastic, a reactive tile material consisting of two components, is also known as epoxy-polyurethane compounds. It is most well-known among builders and finisors because it offers the most dependable adhesion with the base. Adhere tiles to every kind of base imaginable using glue. Additionally, it is perfect for waterproofing high-humidity buildings. After the last hardening, lipoelastic does not shrink.

The following are the specifics of using glue:

• You can not add lime and cement to the product;
• The temperature for application should be within +10 … +35 degrees;
• The ratio for mixing is 4.6 parts of component A, 0.4 parts of component B, another proportion will spoil the glue;
• The spots should be immediately removed before solidified with denatured alcohol.

Litokol

In addition to mineral bases (cement), the glue "Litokol," which is based on polyester and polyurethane resins, also includes a variety of chemical additives. It is frequently utilized for decals on plaster, brick, blocks, and underfloor heating systems. When glue comes into contact with air, it hardens quickly and is affected by temperature changes and mechanical loads. The product works well for mosaics and stickers made of any kind of tile.

Mapei

The Mapei Keralastic is a white polyurethane adhesive that is designed to enable expert tile adhesion. Isocyanate hardener and synthetic fillers are both present in the two-component emulsion.

Applying Mapei Keralastic to plaster, asphalt, concrete, wood, metal, gypsum, and asbestone is appropriate. One of the unique qualities of glue is its quick curing time; tiles bonded to the floor can be used after just 12 hours. The material has a very high resistance to sliding, so even heavy, large-format tiles can be fixed on walls with reliability.

Ceresit

One of the most well-known companies that produces construction mixtures is Cerezit. Two-component adhesives are characterized by their resistance to moisture and frost. Funds have the highest resistance due to the polymer and mineral compounds they contain. Tile glue such as Ceresit CU-22 is one example; it can even be used on deformed bases and is best used in environments with humidity levels above 70%.

Kiilto

Russian glue made of polyurethane, Kiilto PL 250, is solvent-free and eco-friendly. All kinds of tiles, including those with unusual compositions, are adhered to with it. Extruded polystyrene, isolation, and the PVC attachment tool are available for use. Glue creates an elastic, robust seam. It can be used in even the coldest temperatures (between +5 and +10).

Ceramic tile two-component adhesives are perfect for both indoor and outdoor applications because of their remarkable bonding power, robustness, and moisture resistance. These adhesives, which are usually made of a resin and a hardener, react chemically when combined to form a strong, long-lasting bond that is resistant to pressure and adverse weather. They work especially well in places like bathrooms, kitchens, and outdoor patios that are subject to moisture and temperature changes. Two-component adhesives are very easy to use and very effective at keeping ceramic tiles firmly in place for years at a time. They offer a dependable and long-lasting finish for any tile project.

Laying tiles on two -component glue

The base must be properly prepared before using the product. It should not crumble and be mechanically robust and dry. Oil, paint, and dirt stains have been entirely removed from the base. You should be able to tolerate the base for at least a week after pouring a concrete screed for every centimeter of layer thickness. Rust must be removed from metal surfaces, either by hand or with sandblasting equipment. Primers need to be applied beforehand to porous bases.

Two-component glue is carefully diluted in accordance with the directions. The liquid component is linked to the pastey or dry composition. Using high-precision scales is crucial in certain areas, like the kitchen. Water should not be added to glue! While a stick mixer can be used for mixing, a construction mixer works best for three minutes. Depending on the brand, 20 to 40 minutes are typically allotted to work with the final composition.

After pressing the tile into the base, use a gear spatula to apply a 2 mm layer of remedy. Make sure to leave seams for division and compensation. They should be 5 mm along the walls. To get rid of air residues, roll the coating with a roller. You can grout the seams after three hours, though it’s advised to wait for a pause at 24 hours for certain compositions.
