Self-levelling foor levelling compound
A self-levelling universal floor levelling compound. Suitable also for levelling floors that will be be painted. Low alkali.
- general levellings
- coverage 1.6 kg/m²/mm
- walkable: 5 h
- coatable: 10 mm/1 d, 20 mm/3 d
- interior areas
Suitable for levelling floor surfaces at thicknesses of between 3–20 mm before laying the floor covering.
The substrate must be clean, solid and firm. Remove cement laitance and paint splashes, and vacuum the floor thoroughly.
Concrete subfloors are pre-treated with 1:4 diluted Kiilto Start Primer or Primer One (20% Kiilto Primer/80 % water) prior to application of the floor screed. Surfaces under reconstruction as well as board surfaces must be primed with undiluted Kiilto Start Primer or Kiilto PrimerOne before levelling. Non-absorbent substrates, such as ceramic tiles or painted surfaces, can be treated also with Kiilto Fix Primer.
A low alkaline screed layer protects the adhesive and vinyl coating from the damage caused by alkaline moisture in the concrete. The studies have shown that a 5 mm thick screed layer provides the protective effect.
The concrete subfloor must comply with national standards.

Fill the mixing container with the required amount of clean, cool water (+10-25ºC). Strew powder slowly while stirring until a smooth, flexible mass is formed. Let the mix mature for approx. 2 min. and then remix vigorously once before use.
Apply screed evenly by using a steel or notched trowel. Screed can also be applied by using an appropriate floor screed pump.
The drying of the screed must not be accelerated by heat or ventilation, since too quick a drying may cause hair cracks. If the temperature in the levelled room is higher than normal, the relative humidity very low, or if the levelled floor surface is exposed to direct sunlight, we recommend covering the floor with a tarpaulin as soon as it is dry enough to allow walking. The floor should be covered with a flooring relatively soon after it has hardened and dried. This will prevent the surface from over drying, cracking and becoming loose.
Suitable also for floors that are going to be painted in secondary rooms with light traffic, but not, for example, in garages or for bathroom floors, etc.
In areas where waterproofing is used, e.g., bathroom floors, floor levelling should be applied under the waterproofing membrane.
Not suitable for areas permanently under water (e.g., swimming pools).
Note! Avoid excessive use of water, since it will weaken the surface strength and may cause separation or cracking.
