Palace Fast Flex is a high-performance, fast-setting floor levelling compound designed to prepare a wide variety of floor types quickly and efficiently. Whether you're working on tamped concrete, sand/cement screeds, mastic asphalt, plywood, or even power-floated concrete, Fast Flex provides a reliable solution for achieving a perfectly smooth and level surface.
One of the key benefits of Fast Flex is its compatibility with underfloor heating systems. It’s particularly well-suited for use with wire-based sub-tile heating, thanks to its flexible and accommodating nature. This makes it a top choice for modern residential or commercial flooring installations where warmth and efficiency are essential.
Fast Flex delivers excellent flow and levelling, producing a clean, flat surface that’s ready for tiling in as little as 4 hours. It can be applied in depths ranging from 2mm up to 30mm, allowing for versatility in different project scenarios, including both minor corrections and more substantial smoothing jobs.
Its single-part, protein-free formulation makes it suitable for pump application, and it’s safe for use in sensitive environments, including those requiring hygienic standards. After application, the floor is typically ready for foot traffic in just 3 hours and can accept floor coverings within 24 hours.
