Injection adhesive for tile setters - professional repair of loose tiles

The professional method - Injection adhesive for tile layers and craftsmen

Loose tiles and hollow clinkers are a problem most tile layers and craftsmen encounter in their daily work. A cavity under tiles and clinkers arises over time - due to settling in the substrate, moisture exposure, or defects in the original laying. The traditional solution is to break up and re-lay. This is time-consuming, noisy, and creates unnecessary disturbance for the client. ADIN is a patented injection adhesive for tile layers and professional craftsmen that restores the adhesive bond under loose tiles and hollow clinkers without replacement.

What are loose tiles and hollow clinkers?

A loose tile or hollow clinker has lost contact with the substrate. An air pocket has formed between the back of the tile and the tile adhesive - a cavity without load-bearing capacity. If you tap the tile with a hammer handle or a coin, it will emit a hollow, resonant sound. This is the surest sign. In more advanced cases, the tile moves under light pressure, and the grout lines begin to crack along the edges.

The problem occurs in both newer and older buildings and on all types of tiles and clinkers - ceramics, natural stone, and clinkers on floors and walls. In wet rooms, the consequential damages are serious: if water penetrates behind the cladding, moisture damage and the risk of mold growth occur. In dry rooms, the tile is subjected to stress without full support and can break with daily use.

The causes are typically threefold: inadequate adhesive bond during the original laying, settling in the substrate over time, or moisture exposure that breaks down the tile adhesive. In all three cases, the result is the same - a cavity that will not disappear on its own.

The injection method - principle and professional background

The injection method is based on a simple principle: instead of removing the tile and re-laying it, adhesive is introduced under the tile via drill holes in the grout lines. The adhesive fills the air pocket and re-bonds the tile to the substrate - from the inside.

The method places demands on the product. The adhesive must be thin enough to distribute evenly in the cavity. It must cure to a bond that can withstand daily stress. And it must accommodate the movements that naturally occur in a substrate over time - without the break reoccurring.

Adin Glues' two patented technologies

ADIN Glue is based on two patented solutions that differentiate the product from other injection adhesives on the Danish market.

The first is the injection mechanism. It ensures a controlled and even distribution of the adhesive in the cavity - even in irregular cavities. Standard adhesives typically accumulate close to the drill hole and do not cover the cavity to its full extent. ADIN Glue's mechanism actively distributes the adhesive, so the tile is bonded to the substrate over the entire contact surface - not just at points.

The second is the adhesive formula. ADIN is highly elastic, which means that the adhesive can withstand the movements and settling that occur in a substrate over time. Stiff adhesives crack during settling - and the cavity reappears. Highly elastic adhesive follows the movement and maintains the adhesive bond. This is the difference between a repair that lasts for many years and one that needs to be redone.

The two technologies complement each other: precise distribution and durable bonding.

Step-by-step work process

The procedure with ADIN Glue is straightforward and does not require special equipment beyond what a tile layer already has on site.

Systematically tap the affected area with a hammer handle and mark all loose tiles and hollow clinkers with chalk or painter's tape. Map the extent before you begin. Then drill 2-3 mm holes in the adjacent grout lines. Narrower holes provide a cleaner intervention with fewer visible traces.

Thoroughly vacuum the holes for drilling dust and loose particles. Inject ADIN Glue via injection needles until the adhesive meets resistance - this is a sign that the cavity is filled. Work methodically from hole to hole. Close the holes with grout in a matching color. The tile can be walked on shortly after injection, and the work leaves no visible traces.

When ADIN Glue is the right choice

ADIN Glue is used for repairing loose tiles and hollow clinkers in ceramics, natural stone, and clinkers - on floors and walls. It is a professional product that does not require special training. Tile layers, masons, building craftsmen, and others who work professionally with tiles and clinkers.

The product requires that the tile is intact, that the grout is accessible for drilling, and that the substrate's load-bearing capacity is intact. Injection adhesive restores the adhesive bond and can be advantageous to use for foundations that move slightly, such as light, yet solid floor constructions. The product does not replace a foundation that continues to move.

Advantages in daily work

Time saving is the most tangible advantage. A repair with ADIN Glue is completed in a fraction of the time that breaking up and re-laying requires. This means fewer days on site, lower material consumption, and a job that is completed cleanly and invisibly.

The method generates minimal dust and does not require heavy equipment. It is suitable for jobs in occupied homes, hotels, shops, and public institutions - places where the work must be carried out with minimal disturbance.

Breaking up always carries the risk of damage to adjacent tiles, constructions, or the wet room membrane, but injection adhesive for loose tiles and clinkers can eliminate this risk. The tiles remain intact, the grout lines are preserved, and the result is without visible traces.

For the craftsman who offers repair of loose tiles and hollow clinkers as part of his work, ADIN is a method that is easy to explain to the client.

ADIN Glue compared to other products on the market

The Danish market contains very few injection adhesive products aimed at professionals. The injection adhesive is developed in Denmark and patented by ADIN ApS, based in Vejle. The product is designed to solve a well-known problem in the trade - precisely, quickly, and durably.

Where ADIN Glue differs from other products on the market is particularly in user-friendliness and strength. The adhesive's properties and composition are optimized to penetrate effectively under tiles and clinkers, so cavities are eliminated, and the tiles achieve a strong, durable adhesion to the substrate.
