BritFlex S2 Rapidset Tile Adhesive

Ultimate Flexibility and Strength for Professional Tile Installation

The BritFlex S2 Rapidset Tile Adhesive is a premium, highly flexible, polymer-modified adhesive designed to deliver exceptional bonding strength and durability. Ideal for both wall and floor tiles, this professional-grade adhesive is engineered to perform in even the most demanding environments. With its rapid-setting properties, it allows for grouting within just three hours, helping you achieve outstanding results quickly and efficiently.

Perfect for use with ceramic, porcelain and natural stone tiles, the BritFlex S2 Rapidset offers superior adhesion, flexibility and performance — making it the ultimate choice for high-specification residential and commercial tiling projects.

Advanced Polymer Technology for Maximum Flexibility

The BritFlex S2 Rapidset Tile Adhesive has been developed using advanced polymer technology, giving it exceptional flexibility and strength. Classified as an S2 adhesive, it offers the highest level of deformation performance available, meaning it can absorb significant movement or vibration without cracking or losing adhesion.

This makes it ideal for challenging substrates such as timber, underfloor heating systems, or newly laid screeds where thermal or structural movement is expected. Its polymer-rich formulation ensures a durable, long-lasting bond that provides both strength and resilience under pressure.

Perfect for a Wide Range of Tile Applications

The BritFlex S2 Rapidset is designed to work with all popular tile materials and sizes, from small mosaics to large-format tiles. It can be used to fix:

• Porcelain tiles – offering strong adhesion for dense, low-porosity tiles.
• Ceramic tiles – perfect for bathrooms, kitchens and splashbacks.
• Natural stone tiles – such as marble, granite, limestone and slate.
• Mosaics and decorative tiles – delivering precision and easy handling.

Suitable for both interior and exterior applications, this adhesive provides consistent results across all environments. It’s compatible with substrates such as concrete, cement screeds, plasterboard, tile backer boards and existing tiled surfaces (with proper preparation).

Rapid Setting for Faster Completion

The rapid-setting formula of the BritFlex S2 Rapidset Tile Adhesive makes it perfect for fast-track installations where time is critical. It achieves high bond strength quickly, allowing tiles to be grouted and floors walked on within three to four hours of application. Despite its quick-drying nature, it provides excellent open time and workability, ensuring you have enough flexibility during installation to position tiles precisely.

This makes it an ideal choice for commercial spaces, retail projects and residential renovations where minimal downtime is essential.

Suitable for Underfloor Heating and Movement-Prone Surfaces

Thanks to its high elasticity, the BritFlex S2 Rapidset Tile Adhesive is perfect for use with underfloor heating systems. It accommodates the expansion and contraction caused by changes in temperature, ensuring tiles remain secure and crack-free over time.

The adhesive’s flexibility also makes it suitable for tiling onto plywood overlays, anhydrite screeds and other substrates where minor movement or vibration may occur. This performance advantage makes it one of the most versatile and reliable adhesives in its class.

Water-Resistant and Weatherproof Performance

The BritFlex S2 Rapidset isn’t just strong — it’s built to withstand the elements. The adhesive is both water- and frost-resistant, making it suitable for outdoor tiling projects such as patios, balconies, terraces and external steps. Indoors, it performs equally well in wet environments like bathrooms, showers and utility rooms.

Once cured, it provides a dense, waterproof bond that prevents water penetration and protects both tiles and substrates from moisture damage. Its durability ensures lasting performance even in areas exposed to humidity and temperature changes.

Easy to Mix and Apply

Ease of use is a hallmark of the BritFlex S2 Rapidset Tile Adhesive. Simply mix the powder with clean water to achieve a smooth, lump-free consistency. The adhesive spreads effortlessly with a notched trowel, providing excellent coverage and minimal wastage.

It offers a comfortable working time, allowing for careful alignment and adjustment of tiles, and its low-slip formulation makes it ideal for vertical applications such as walls and splashbacks. Once cured, it forms a solid, flexible bond that’s built to last.

Application and Coverage

Before applying, ensure surfaces are clean, dry and free from grease, dust or loose material. Mix the adhesive according to instructions until smooth, then spread evenly with a suitable notched trowel. Press tiles firmly into place, ensuring full coverage. Allow to set for the specified time before grouting or applying load.

Coverage will depend on tile size, substrate condition and trowel type, but a 20kg bag typically covers several square metres.
