Key Advantages
High S1 Flexibility
The S1-class flexible structure allows the adhesive to adapt to substrate movement, thermal expansion, and contraction, reducing the risk of cracking and tile detachment.
Strong Bonding Performance
Its high adhesion strength ensures reliable fixation of heavy and large-format coverings, including porcelain, granite, and natural stone.
Reduced Slip Performance
The anti-slip formulation prevents tile movement during installation, allowing easier and more precise application on vertical surfaces.
Extended Working Time
The long open time provides installers with additional flexibility and improves application efficiency.
Interior and Exterior Use
Kalekim 1059 Ultratech offers reliable performance in various environments, from indoor wet areas to demanding exterior applications.
Installation Instructions
1. Surface Preparation
The application surface must be:
-
Clean
-
Dry
-
Strong and stable
-
Free from dust, oil, grease, and loose particles
Surface repairs should be completed before installation if required.
2. Mixing
Mix one 25 kg bag of Kalekim 1059 Ultratech 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 application.
3. Application
Apply the adhesive using a suitable notched trowel.
Install ceramic tiles, porcelain, or stone coverings within the open time and press firmly to ensure proper contact.
For large-format tiles, a combined application method (back-buttering + substrate application) is recommended for maximum coverage.
4. Grouting
Wait at least 24 hours after installation before applying grout.
Use a suitable grout product according to the project requirements.
