Application

This liquid screed can be used to produce a smooth, flat, and level floor to form the sub-base for subsequent floor coverings for internal floors in, among others:

  • Houses.
  • Apartment schemes.
  • Schools.
  • Hospitals.
  • Offices.


Specially trained screeders pump the screed into place by using specialized equipment. This screed is LKAB Minerals' most popular screed, notably because it offers a cost-effective and environmentally friendly alternative to cement-based screeds.
