Self-levelling screed is commonly used for levelling of pour substrates to achieve finer tolerance for the installation of tiles, carpets etc. It can also be used as a flooring finish in itself due to its strength and resistance to abrasion. It can be applied over concrete or screed. The installation thickness may vary however, there are solutions that range from 0mm up to 40mm in one application. Most self-levelling screeds are fast drying and depending on the product, the surface can be walked on between 3-24 hours after it has been applied.

Based on the type of self-levelling screed used, you will be able to walk on it after 2-3 hours due to its fast-drying properties. While it’s possible to walk on it after this time, it can a day or more to completely dry out.
It is extremely easy to mix and apply self-levelling screeds as it’s based on a pumpable system. This results in larger areas being completed in much faster times than traditional sand and cement screed.
While cement and sand screed can take up to 3 to 7 days to harden, self-levelling screed due to its rapid early strengthening properties can withstand light vehicular traffic after 48 hours.
Due to its light-weight nature, self-levelling screeds can be used for high performance floating, bonded, and unbonded screeds without overloading existing floor slabs. They are suited for large commercial projects.
