Application

For levelling solid bonded substrates:

• Concrete

• Sand/ cement screeds

• Anhydrite screeds

• Can also be used as a levelling compound for any of our weberfloor base or renovation screeds

• Vinyl / Linoleum

• Carpet

• Laminate flooring

• Parquet flooring*

• Tiles

* May require extended time before covering

Description

weberfloor smooth 4150 is designed for use in residential and commercial areas allowing a much earlier overlay compared to traditional sand / cement, concrete or anhydrite screeds. It provides a smooth and strong finish ideal for receiving a range of final floor coverings.


Features and benefits:

  • For application depths between 2-30 mm.
  • Weber Low Dust TechnologyTM improves comfort of applicators.
  • Pump or hand applied.
  • Foot traffic after 2-4 hours.
  • Final floor covering installed in as little as 3 days.
  • Excellent spreading and smoothing characteristics
  • Low alkalinity.
  • Casein-free.
  • Low emissions.


Constraints:

• Not to be left without a suitable floor covering.

• Not to be used where some movement is expected (e.g. underfloor heating).


For these substrates the floor should be levelled with weberfloor fibre 4310 or weberfloor fibre rapid 4320. Please see relevant datasheets for more details.
