Description
Sika’s Sikafloor-4020 FiberLevel is a fibre-reinforced, fast-drying self-levelling and smoothing compound for internal floors. The fibres in the mix help it bridge minor substrate movement and hold together at the thicker end of its 3 to 20mm application range, which is useful when levelling an uneven concrete slab or timber floor ahead of tiles.
It is a preparation layer, not a finished floor. Once dry it becomes the substrate for tiling or other coverings, and it is not intended to be left exposed as a trafficable surface. The fast-drying formulation means a tiler can move from levelling to tiling in the same working day rather than losing a day to a slower-curing compound, which matters on programme-driven commercial jobs as much as it does for a homeowner wanting the job finished quickly.

Where to Use
- Levelling and smoothing concrete floors ahead of tiles or floor coverings
- Timber, CFC sheeting and Scyon substrates that are firmly fixed and dimensionally stable
- Fast-track jobs needing a quick-drying preparation layer
- Not recommended as a trafficable wearing surface on its own
Coverage
| Thickness | Coverage per 12L mixed |
|---|---|
| 3mm | Approx. 4 m² |
How to Apply
- Check the substrate — it must be permanently dry, structurally sound, clean, and show no signs of delamination or movement; timber substrates need to be firmly fixed and dimensionally stable.
- Mix — combine 4.3 to 4.4 litres of clean water with the 20kg bag to a smooth, lump-free consistency.
- Pour and level — place within the roughly 20 minute pot life and allow it to self-level at the required thickness, 3 to 20mm.
- Allow to dry — light traffic after around 2 hours; allow a further minimum 2 hours’ drying before tiling.
Important Notes
- All relevant AU/NZ standards for the substrate type must be followed alongside this datasheet.
- Timber, CFC sheeting and Scyon substrates must be firmly fixed, permanently dry and dimensionally stable before application.
- Not recommended as a final trafficable wearing surface.
