Sikafloor®-4020 FiberLevel
Our hybrid technology of low tension calcium sulphate combines with fast drying of cementitious systems. This special high polymer formulation and embedded fibres provide reinforcement suitable for wood, timber or CFC type subfloors.
- Fiber reinforced
- High compressive & flexural strength
- Very low VOC
- Fast drying
- Light foot trafic after 2hrs
- Good potlife
- Install moisture sensitive flooring after 6hrs
- Versatile subfloor application
Usage
▪ Recommended underlayment for all Commercial &Domestic floor coverings
▪ Suitable to be applied over semi-flexible substrates such as soundly fixed/adhered timber, chip board, plywood or CFC sheet
▪ Suitable to be applied with underfloor heating systems
▪ Levelling of new or old concrete substrates ▪ Levelling over soundly adhered tiles, stone or vinyl
▪ Interior applications

Layer thickness
3 - 20 mm
Ambient air temperature
+5 ºC min / -35 ºC max.
Substrate temperature
+5 ºC min / ~30 ºC max.
Pot Life
~20 min. at 23 ºC
Waiting time to overcoating

EQUIPMENT
High speed heavy duty electric drill, mixing paddle &
suitable size bucket/vessel - 20L +
MIXING
- Mix the entire 20kg bag of Sikafloor®-4020 Fiberlevel with 4.3 - 4.4 Litres of clean, cool water.
- Slowly add powder to the water while mixing thoroughly at high speed for 2 minutes to a lump free consistency.
- Let product stand for 2 minutes, then re-stir for another 30 seconds before applying mixed product
Note, not mixing for the recommended time, at high speed, letting the product stand or additional water may result in poor product performance and possible failure.
APPLICATION
- Pour or Pump Sikafloor®-4020 FiberLevel, then spread with a long handled stand up trowel as required.
- For touch-ups, use a flat steel hand trowel.
- Areas of application must have fresh airflow to assist with product hydration and drying. Closed off rooms with no fresh air will retard the curing/drying process and possibly lead to product failure.
Note, If a second layer of Sikafloor®-4020 FiberLevel is to be applied, the first layer should be primed with Sikafloor®-01 Primer (AU) or Sikafloor® 08 Primer (AU) diluted 1:1 with clean cool water. The second layer may not exceed the layer thickness of the first.
CLEANING OF EQUIPMENT
Clean tools and equipment with warm water and detergent while the product is still wet.
