Generally applied between 0mm and 50mm thickness.
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 3-24hours after it has been applied.
Self-levelling screed properties:
Comercial self-levelling screed is used for smoothing out new or existing concrete and the screed substrates can vary in thickness from 5-40mm. All the different commercial toppings have slightly different specifications. If you would like to read more about the different commercial toppings that are used by Screedfast, follow the linkes to Tekfloor 025 Industrial, Ardex K80 and Mapei Ultratop Industrial.
Weberfloor flex is a high-performance, fibre-modified, cement-based, self-smoothing, self-levelling and rapid setting setting floor screed with low dust technology. For more information about Weber flex fibre screed, please go to our technical page.
Fibre self-levellling screed can be applied up to 50mm in thickness. It is rapid setting resulting in light foot traffic being possible after 1-2 hours. It has a better bond to difficult substrates, is flexible allowing to absorb the limited movement that is caused by for example the underfloor heating and it is also fibre-modified for increased resilience.For levelling:
