Professional SLC 1550 FLEX is a one part, quick drying, flexible, universal reparation screed which utilises microfibre technology.

Made from a curated blend of cements, special sands, and synthetic polymers, this high quality compound is both smoothing and self-leveling. Ideal for use in either domestic or commercial situations, where leveling of up to 50mm is required, this product is applied in one application and has a quick turnaround time.

It can also be used over underfloor heating and on more difficult substrates, such as timber. The finish is not designed to be wearing - but provides an optimum surface to receive a variety of floor finishes including: tiles, natural stone, ceramic tiles, resin coatings, vinyl etc. It's perfect for buildings such as offices, houses, schools, airports, and hospitals.
