Kiilto Pro Easyrapid
Fast-setting smoothing compound

A very rapid smoothing compound for finishing levellings in indoor areas. Patching up to 10 mm. Walkable approx. 45 min. Ready to receive a floor covering as soon as 1–2 h from levelling. Concrete or levelling compound substrates do not need priming. Low alkali. Cementitious.

Special features

  • light and easy to spread, paste consistency
  • for fast finishing levellings in wet areas or dry indoor areas
  • coverage 1.1 kg/m²/mm
  • long working time, gains strength fast
  • coatable 1–2 h




A fast-setting pastelike smoothing compound for floors at thicknesses between 0–5 mm before laying a floor covering. For smaller areas, e.g. patching and filling, up to 10 mm. For thicker layers we recommend Maxirapid. Pro Easyrapid is not recommended for subfloor smoothing under glued down parquet flooring.

The substrate must be clean, solid and firm. Remove cement laitance, paint splashes and other impurities, and brush or vacuum the floor properly. Rough, uneven areas and high ridges in concrete must be sanded before the levelling. When patching, filling holes or levelling concrete or levelling compound substrate, no priming is needed. Renovation substrates, as well as board substrates, must be primed with undiluted Kiilto Start Primer before smoothing.

Instructions for use

Fill the mixing container with the required amount of clean water. Strew powder while stirring in cool (+10–20 °C), clean water until a smooth, pastelike mass is formed. Apply immediately to a clean surface using a steel trowel.

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.

Not recommended for smoothing of floors to be painted.

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!
