Kiilto 97 DF Lattiatasoite 1-7 mm
Dust reduced smoothing compound for floors before laying the floor covering. Good levelling properties. Low alkali.
Special features
- for smoothing floors
- good filling properties
- walkable after 4 h
- pumpable
- good self-levelling properties
- coatable after 24 h
Application
Suitable for levelling floor surfaces at thicknesses 1-7 mm before laying the floor covering.
The substrate must be clean, solid and firm. Remove cement laitance, paint splashes, adhesive residue and other impurities and vacuum the floor properly.
Concrete subfloors are pre-treated with 1:4 diluted Kiilto Start or PrimerOne primer (20% Kiilto Primer / 80 % water) prior to floor screed. Surfaces under reconstruction as well as board surfaces must be primed with undiluted Kiilto Start Primer or PrimerOne before levelling. Non-absorbent substrates, such as ceramic tiles or painted surfaces, can also be treated 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 substrate must comply with national standards.
Coverage
1 mm layer/m² solid matter weighs approx. 1.6 kg (approx. 12 litres of screed/bag).

Instructions for use
Fill the mixing container with the required amount of clean water. Strew Kiilto 97 DF -powder slowly while stirring in cool (+10–25 °C), clean water until a smooth, flexible mass is formed. Let the mix mature for approx. 2 min and then remix once before use.
Apply the smoothing compound evenly by using a steel or notched trowel. It can be applied also by an appropriate floor screed pump. The layer must be dry before applying a new one.
The drying of the smoothing compound must not be accelerated e.g. by heat or ventilation, since too fast drying may cause hair cracks. If the temperature in the levelled room is higher than normally, 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 loosening.
Suitable also for floors to be painted in secondary rooms with light traffic, but not for example for garages or bathrooms floors etc.
In areas where waterproofing is used, for example 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 and cracking.
Environment and safety
