When your commercial or residential project demands speed and heavy-duty structural reliability, Larsen Trade Fast Set Flex – Grey – 20kg stands out as the ultimate choice. This professional-grade adhesive is formulated with advanced flexible polymers, allowing it to withstand thermal expansion from underfloor heating systems and minor structural movement without cracking. Its quick-setting properties ensure that your newly tiled surfaces are secure and ready for grout in just a fraction of the time required by standard adhesives.
This robust grey adhesive mix is highly versatile, making it perfect for bedding ceramic, porcelain, slate, quarry, and natural stone tiles. It performs exceptionally well on a wide range of substrates, including solid concrete, sand/cement screeds, plasterboard, and properly primed timber panels. Because it hardens rapidly even in challenging conditions, it is highly recommended for busy walkthrough entries, kitchen floor layouts, wet rooms, and external pathways where downtime must be kept to an absolute minimum.

Fitting
To secure an immaculate, structural result with your Larsen Trade Fast Set Flex – Grey – 20kg, ensure the background substrate is structurally sound, clean, flat, completely dry, and free of loose dust or oil. Highly porous plaster or old concrete walls should be primed before applying the mixture. Pour the powder slowly into a bucket of clean water and mix with a mechanical paddle drill until a smooth, lump-free paste is achieved. Apply the adhesive with an appropriate notched trowel, press your tiles firmly into the wet ribbed bed with a slight twisting motion to ensure full transfer, and complete your installation quickly as the mix has a limited pot life once prepared.
