Extra fast curing levelling screed for levelling floors, filling and patching gaps and making floor slopes before over levelling and/or laying the floor covering, at thicknesses of 1–30 mm. For over levellings we recommend using, e.g., Kiilto 97 DF, TopPlan DF or Tasoflex levelling compounds. Suitable for interior and exterior use. In exterior applications, minimum layer thickness is 5 mm.
The substrate must be clean, solid and firm. Remove cement laitance and paint splashes, and brush or vacuum the floor thoroughly. Rough uneven areas and high ridges must be sanded before levelling.
Concrete subfloors are pre-treated with diluted Kiilto Start Primer (10–20 % Kiilto Start Primer / 80–90 % water) prior to application of the floor screed. Surfaces under reconstruction as well as board surfaces must be primed with undiluted Kiilto Start Primer before levelling. In outdoor applications and with non-absorbent substrates prime the substrate with Kiilto Fix Primer or make a bond bridge with, e.g., Kiilto Saneerauslaasti cementitious adhesive with a notched trowel. In ground supported structures, the capillary rise of moisture must be prevented.
The concrete substrate must comply with national standards (in Finland SisäRYL 2013 and BY 45).

Mix 20 kg levelling screed powder with 4.0–4.5 l of cool water and stir continuously until a smooth, plastic mix is formed. Apply immediately to a clean floor by using a steel trowel. The floor is walkable in about 45 minutes, and the floor covering can be laid after approx. 2 hours.
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.
Also suitable for floors to be painted in secondary, lightly trafficked areas, but not suitable, for example, for garage floors, wet room 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! Using more water than instructed will retard the drying process and weaken the strength of the concrete. It may also cause separation and cracking.
