On Exterior Surfaces: Used for adhering rock wool boards to surfaces such as exposed concrete, aerated concrete, brick, pumice, and plaster. It is utilized in thermal insulation systems for attaching insulation boards.
In Interior Spaces: Used for bonding rock wool boards to walls, ceilings, and floors. It is also applied for thermal and acoustic insulation in partition walls and suspended ceilings.
Other Applications:
• Used for bonding XPS boards in roof insulation applications.
• Applied in prefabricated buildings for adhering rock wool boards.
• Utilized in cold storage facilities and other industrial applications for bonding rock wool boards.

The surface preparation before applying rock wool board adhesive is one of the most crucial factors affecting the adhesive’s effectiveness and durability. If the application is carried out without proper surface preparation, the adhesive’s adhesion to the surface weakens, leading to displacement or detachment of the boards.
• Cleaning: The application surface must be clean and free of dust. Dust, dirt, oil, paint residues, and other contaminants can prevent the material from adhering properly. The surface should be cleaned using sweeping, brushing, or vacuuming.
• Removal of Old Coatings and Weak Layers: If the surface has old waterproofing materials, paint, or other coatings, these should be completely removed. The presence of weak or loose layers can hinder the material’s effective adhesion.
• Repair and Filling: If there are cracks, holes, or other irregularities on the surface, appropriate repair materials or fillers should be used to smooth them out.
• Moisture Control: The moisture level of the surface should be checked. The moisture content should be below 5%. If the surface has a high moisture level, it should be left to dry before application.
• Surface Water Absorption: If the application surface is concrete, its water content should be checked. The concrete surface must be adequately dried; otherwise, the adhesion performance of the thermal insulation board may be negatively affected.
• Primer Application (Optional): In some cases, a primer can be applied to the surface. A primer helps improve adhesion, smooth rough surfaces, and regulate the surface’s water absorption capacity.
• Pre-Application Test: After surface preparation is completed, a small test application can be performed before applying the thermal insulation material. This test helps verify the material’s adhesion capability and suitability.

An appropriate amount of water (6-6.5 liters of water per 25 kg bag) is added to the mixing container. The powder material is added and mixed with a low-speed hand mixer. The mixture is allowed to rest for 5 minutes and then mixed again until a homogeneous consistency is achieved. The mortar is spread onto the thermal insulation board with a trowel and combed using an appropriate notched trowel. If the surface is not suitable, a dot-and-dab application method can be used. The boards are pressed onto the surface with suitable pressure. Once the adhesive has sufficiently cured, mechanical doweling is performed. The adhesive is generally applied using a notched trowel or spatula. It is important to distribute the adhesive evenly on the surface. The board or panels should be placed immediately after applying the adhesive while it is still wet.
Pressure and Fixation: A light pressure should be applied to the boards after the adhesive is applied. This ensures the adhesive settles properly and forms an effective bond. If necessary, clamps or weights can be used to keep the boards in place.

• No foreign materials (lime, cement, gypsum, etc.) should be added to the prepared mortar.
• Expired mortar should not be reused by mixing it with water or dry mortar.
• It is recommended to apply the material at temperatures between +5°C and +35°C.
• Protect against rapid drying in windy weather conditions.
• Do not apply on frozen surfaces.
• Avoid direct application under sunlight.
• Do not exceed the specified application area and instructions for use.
• Do not inhale directly. In case of eye contact, rinse immediately with plenty of water and seek medical advice if necessary.
• The full curing process should be completed, as the adhesive may not reach maximum strength before full curing.
