Key Advantages
S1 Flexibility Performance
The S1 deformability classification enables the adhesive to absorb movement caused by thermal expansion, contraction, and minor substrate deformation.
Superior Bond Strength
Its advanced polymer-modified formulation provides reliable adhesion for heavy and large-format coverings, ensuring long-term installation stability.
Reduced Slip
The non-slip formula improves installation accuracy, especially on vertical surfaces and wall applications.
Extended Open Time
The extended working time allows installers greater flexibility and efficiency during application.
Indoor and Outdoor Suitability
Kalekim 1056 performs reliably in a wide range of environmental conditions, making it suitable for both interior and exterior installations.
Installation Instructions
1. Surface Preparation
Before application, the substrate should be:
-
Clean
-
Dry
-
Structurally sound
-
Free from dust, grease, oil, and loose particles
Proper substrate preparation is essential for optimal adhesion.
2. Mixing
Mix one 25 kg bag of Kalekim 1056 with approximately 6.5–7.5 liters of clean water using a low-speed mixer until a smooth and homogeneous consistency is achieved.
Allow the mixture to rest for approximately 5 minutes, then remix before use.
3. Application
Spread the adhesive evenly using an appropriate notched trowel.
Install tiles within the specified open time and press firmly into position.
For large-format tiles and stone coverings, a double-spread (buttering-floating) application method is recommended to achieve maximum coverage and adhesion.
4. Grouting
Allow the adhesive to cure for at least 24 hours before applying grout.
Use a suitable grout product compatible with the installation requirements.
