After the liquid screed has been laid a thin layer of laitance is left on the surface, this means that the floor will need to be sanded. (please note this may not always be the case depending on your environment please ask a member of our staff what product has been installed before booking the floor to be sanded.)

The floor sanding process

The floor sanding should be done approximately 7-10 days after application. This will not only help the drying out process but will also provide a stable surface on which to tile onto.

The process of sanding is performed using specialised machines and is best completed by professional service providers. Before starting this process, the floor is cleaned to make it clear of any sort of nails or other sharp materials. These sharp materials can damage the sanding machine.

Using a diamond cutting pad the floor is sanded removing any laitance that may be present. No matter what flooring is applied sanding is recommended to all areas where anything is stuck to the floor. This improves the durability of the floor and avoids further troubles in the process of applying any final floor coverings like tiles, flags, carpet, vinyl, micro cement, and hardwood. Once the floor has been shaded and keyed a calcium sulphate compatible primer should be applied after the floor has been sanded and only after the floor has completely dried to the recommended moisture levels at which point a floor covering can be applied.
