Keraquick Easy S1 Flexible Rapid-Set Tile Adhesive
Keraquick Easy S1 is a high-performance, rapid-setting, deformable cementitious tile adhesive designed for fast-track tiling projects. Developed for professional reliability and easy application, it delivers excellent bond strength and flexibility, making it ideal for use over electrical and wet underfloor heating systems. Suitable for walls and floors, it supports efficient installations without compromising on performance.
Key Features and Benefits
- Rapid-setting formula - ideal for time-critical projects
- S1 deformable classification - accommodates slight substrate movement
- High bond strength for secure fixing of ceramic, porcelain and natural stone tiles
- Extended open time for easier tile positioning
- Smooth, easy-spread consistency for faster application
- Suitable for internal and external use
- Low shrinkage with excellent resistance to stress
Suitable Applications and Compatibility
Keraquick Easy S1 is suitable for fixing a wide range of tile types including porcelain, ceramic, vitrified tiles and moisture-stable natural stone. It can be applied to:
- Heated screeds incorporating wet underfloor heating
- Electrical underfloor heating mats and cables embedded in levelling compounds
- Cement-based screeds and concrete substrates
- Tile backer boards and suitable insulation boards
- Existing tiled surfaces (subject to preparation)
- Internal floors and walls, including kitchens, bathrooms and high-traffic areas
Its deformable properties make it particularly suitable where thermal movement is expected, such as heated floor constructions.
Role in Underfloor Heating
When installing tiles over underfloor heating systems, flexibility and bond strength are critical. Temperature fluctuations cause expansion and contraction within the floor build-up. As an S1 flexible tile adhesive, Keraquick Easy S1 absorbs these stresses, reducing the risk of cracking or tile debonding.
The rapid-setting formulation also supports efficient project turnaround, allowing earlier grouting and commissioning compared to standard-setting adhesives. This makes it an excellent choice for both professional installers and experienced DIY customers working on heating upgrades or new floor installations.
Guidance
Ensure heating systems are fully commissioned and brought to operating temperature before installation, then switched off prior to applying adhesive. Substrates must be sound, clean and properly prepared. Always follow current tiling standards and underfloor heating commissioning guidance before gradually bringing the system back up to temperature after installation.
