Intelligent reinforced levelling compound

8 02 2016

The high performance, fibre-modified weberfloor 4310 fibre flow floor levelling compound by Saint-Gobain Weber is proving to be the perfect answer for the fast and efficient renovation of existing floors, and floating floor construction, in domestic and commercial applications.

weberfloor 4310 fibre flow is a pump-applied screed formulated from special cements, aggregates, binders and chemical admixtures that can be applied at depths between 5 – 50mm.  It is supplied as a casein-free pre-blended dry powder and is suitable for levelling concrete, lightweight concrete, wooden boards, existing tiles and under-floor heating systems.

“This technical product has been used extensively in the refurbishment of our own commercial accommodation here in Bedfordshire,” says Tracey Dempster, marketing manager, Saint-Gobain Weber, “in the preparation of the conference room and boardroom. Speed of application has been critical as these facilities are used extensively by senior staff and overseas visitors so down-time must be minimal.  In addition to efficient pump application weberfloor 4310 fibre flow can receive foot traffic after just 2 – 4 hours which is a huge benefit.”

With excellent spreading and smoothing characteristics weberfloor 4310 fibre flow can be covered after 1 – 3 weeks following installation, depending on layer thickness and drying conditions, with ceramic and terrazzo tiles, carpet, flexible floor coverings and parquet, and is suitable for heated and wooden floors.  The fibre-modified formulation improves durability and robustness.

After thorough cleaning, the substrate should be prepared with weberfloor 4716 primer to improve adhesion and prevent the formation of air bubbles.  For floating floors weberfloor 4945 fibre mesh is recommended.  Supplied in 25kg polythene-lined paper sacks the screed has a pot life of 20 minutes after adding water.  This high performance screed has low alkalinity and low emissions.
