This wide applicability ensures that it can handle almost any tiling challenge.

The adhesive is suitable for multiple materials such as porcelain tiles, low thickness slabs, ceramic tiles, large size tiles, natural stone, recomposed materials, glass mosaics, thermal and acoustic insulation, terracotta, and klinker.

Kerakoll Setaflex Rapid S1 is designed for both internal and external use, making it suitable for overlaying, terraces, balconies, swimming pools, saunas, spas, and even street furniture.

Preparation and application are straightforward. The substrate must comply with BS 5385 parts 1-5, ensuring it is level, cured, undamaged, compact, rigid, dry, and free from any debonding agents. For highly absorbent concrete substrates, it is recommended to dampen them or apply a coat of Primer A Eco. The adhesive should be mixed with water as per the guidelines to achieve the desired consistency for application.

Kerakoll Setaflex Rapid S1 guarantees superior adhesion, even in challenging conditions such as heat ageing, water immersion, and freeze-thaw cycles. It performs reliably with a shear adhesion of ? 2.5 N/mm² for porcelain tiles after 28 days and a tensile adhesion of ? 2.5 N/mm² for concrete and porcelain tiles. The adhesive’s working temperature range is from -40 °C to +90 °C, ensuring versatility in various climates and conditions.

Overall, Kerakoll Setaflex Rapid S1 Tile Adhesive White 20kg is a comprehensive, high-performance solution for all your tiling needs, providing durability, flexibility, and eco-friendliness.
