Screed floor sanding service in Yorkshire, Humberside & North Lincolnshire

When installing an Anhydrite (Calcium Sulfate) flowing screed floor, a layer of laitance will form on the surface. This laitance must be removed by sanding 7 days onwards from installation, this is essential to aid in the drying process. The removal of laitance is also imperative if a bonded floor finish, such as tiles are to be adhered to the screed.
