SaffroFlex 2k(PUA-666)

Saffroflex PUA-666 is a high-performance, two-component polyurethane adhesive specially formulated for bonding tiles and stones to a variety of challenging substrates. Its excellent elastic flexibility, strong adhesion, and resistance to thermal shock make it suitable for both interior and exterior applications. It is ideal for cladding on high-rise buildings and deformable surfaces, including heated floors and substrates prone to expansion or vibration.

Application Guide

Ensure the substrate is solid, clean, dry, and free from contaminants such as oil, grease, or dust. For newly installed cement screeds, ensure the moisture content is below 5%. Tiles should be dry and free of any substances that could affect adhesion.
Mix Saffroflex 2K PU-666 by blending part A and part B in a 4:1 ratio using a low-speed (approximately 400 RPM) helical agitator. Mix until a smooth, uniform, and consistently colored paste is achieved.
Prepare only the amount of adhesive that can be used within one hour at +25°C and 50% relative humidity to maintain the adhesive’s workability.
Apply adhesive to the substrate using the flat side of the trowel to press it into the surface. Then, use the notched side of the trowel to spread a uniform layer, ensuring proper bonding.
For areas that can be tiled within 20 minutes, spread only as much adhesive as required. For large-format tiles (greater than 12” x 12”), back buttering is recommended to ensure full bedding and support.
Place tiles gently into the adhesive, using a beating block and rubber mallet to embed them securely and adjust for evenness.
Check adhesive transfer by removing a tile and inspecting its back. If the adhesive has dried or developed a skin, remove it and replace with fresh adhesive to ensure proper adhesion.
For timber floors, ensure adequate rigidity, and provide ventilation beneath the flooring. Strengthen tongue-and-groove or parquet floors with exterior-grade plywood to ensure stability before tiling.
