Cracks  in  the  screed  must always be repaired. For this purpose, special reaction  resins  can  be  used  that  feature a low viscosity (very liquid consistency) and rapid hardening.

Undercoats  and  primers  form the bonding bridge between the substrate and the  levelling  compound  or  the  adhesive  applied  on  top. Their use is prescribed  by DIN 18365 "Flooring Works". It is always necessary to follow the manufacturer's instructions for use.

These  mortars  of  non-slump,  stiff consistency are among others used for repairing  cracks  and holes in concrete/screeds, for levelling out extreme differences  in height, for providing a transition between different layers and for producing slopes.

Different  types  of  levelling  compounds  can  be  used to ensure an even surface of uniform absorbency prior to bonding the floor covering.

Screeds  form  the  load distribution layer. They are normally installed on top  of  concrete  floors.  When produced as in-situ screeds, they are made from  aggregates (gravel, sand etc.) and suitable binders. A fine aggregate is used for screed production in order to ensure layers with a smoother and more even surface.

Our high-quality Ceresit additives help you to enhance special properties of the used cement screeds. For reinforced and plain screeds.
