Palace 20kg Multiflex Rapid Set Adhesive

Palace Multiflex is a high-performance, rapid-setting tile adhesive designed for professional and DIY use alike. Formulated with advanced polymer technology, this cement-based, thin-bed adhesive is ideal for fixing a wide range of ceramic, porcelain, vitrified, mosaic, and natural stone tiles. Whether you're working on a bathroom renovation, a heated kitchen floor, or an exterior patio, Multiflex offers the strength and flexibility you need for a long-lasting finish. This adhesive is suitable for both internal and external applications, and it performs reliably across various surfaces, including tile backer boards, power-floated concrete, and existing tiles. It’s also compatible with underfloor heating systems, making it the go-to solution for modern tiled floors that require excellent thermal conductivity. Multiflex is available in both grey and white options, allowing you to choose the best match for your tile type and colour. For timber or plywood substrates, ensure that the surface is either removed or securely fixed and overlaid with a suitable tile backer board to provide a solid base for tiling. This adhesive meets the BS EN 12004 C2FT-S1 standard, meaning it offers enhanced performance: C2 for improved bond strength, F for fast setting, and S1 for flexibility under slight movement—ideal for substrates subject to expansion or vibration.

Frequently Asked Questions

Can I use Multiflex on heated floors?

Yes, Multiflex is fully compatible with electric and water-based underfloor heating systems. It offers the flexibility and thermal conductivity needed to perform under fluctuating temperatures.

What surfaces can Multiflex be applied to?

Multiflex is highly versatile and can be used on tile backer boards, concrete, existing tiles, screeds, and even over sub-floor heating systems. For timber or plywood floors, the surface should be reinforced with an appropriate tile backer board for stability.

How long does it take to set?

As a rapid-set adhesive, Multiflex begins to set within a few hours, depending on site conditions like temperature and humidity. This means you can grout and walk on the surface the same day, ideal for time-sensitive projects.
