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 around 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.  Any excess plaster may be recovered and reused. If you apply several layers of plaster, allow the previous layer to fully harden before applying the next layer. Depending on the conditions, hardening takes one to two days. If necessary, the dried surface is sanded after each plaster application. The levelled surface can be treated with LRF or wallpapered or painted.

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 putty. Surfaces must be levelled in accordance with the general quality standards for indoor renovations (SisäRYL 2013).
