Mixing

Refer to the package for how much water the levelling compound requires. Add the dry material to the water and mix with a drill paddle for around one to two minutes. Let the levelling compound stand for at least fifteen minutes and mix it again for a short while. The finished levelling compound remains workable for one day. The adhesion and wear resistance of the levelling compound can be improved by replacing 10% of the water with Fescon Primer.

Work instructions

The base should be solid, clean and free from any dust or other materials that could compromise adhesion. Before starting work, all structural components at risk of being damaged during levelling must be protected. Apply the levelling plaster on the surface (surface moisture must be below 90%) using either a plaster sprayer or steel trowel. You can recover and reuse any extra compound. When applying several layers of the levelling compound, allow the previous layer to harden completely before applying the next layer. Depending on the conditions, the hardening will take one to two days. If necessary, the dried surface is ground after the application of each layer of levelling compound. The levelled surface can be papered or painted.

Service instructions

A levelled surface that has gotten dirty can be vacuumed, re-levelled, painted or papered in accordance with the instructions of the paint or wallpaper manufacturer.

Other considerations

Do not leave the levelling compound in the pumps and hoses for longer than a day. Excess moisture of the structure may cause yellowing of the levelling compound.
