weberfloor Flex Levelling Compound 25kg

Description

weberfloor Flex Levelling Compound is a high-performance, fibre-modified, cement-based, self-smoothing, rapid-setting floor screed with low dust technology and formulated from special cements, aggregates and chemical admixtures. Supplied in 25kg bags.

It is designed for use in residential and commercial areas, correcting surface irregularities on difficult surfaces, including wood, in interior situations, ideal for rapid completion of tiling projects.

weberfloor Flex Levelling Compound features Weber Low Dust Technology, which improves the comfort of applicators by reducing the amount of dust released into the local atmosphere when the product is mixed. It also has excellent levelling properties and can be built up to 50mm in depth.

weberfloor Flex Levelling Compound is rapid setting – tiles can be laid after 1 – 2 hours. It bonds well to difficult substrates and as it is fibre-modified it has the flexibility and resilience to absorb limited movement, such as on substrates with under-floor heating and wooden substrates.

weberfloor Flex Levelling Compound can be used for levelling:

• Cement screeds, concrete slabs and pre-cast elements
• Floors with under-floor heating or under tile warming
• Wooden flooring (plywood and particle board panels)
• Existing ceramic and rigid plastic tiles
• Floating floors

It is suitable for covering with:

• Tiles
• Flexible floor coverings
• Parquet flooring

Please Note: weberfloor Flex Levelling Compound is NOT suitable for:

• Exterior use
• Floors with rising damp
• Industrial areas
• As a wearing surface

Priming the substrate prior to application with weber PR360 Tiling Primer is recommended to improve adhesion, reduce air bubbles, improve the flow of the screed and prevent de-watering. In situations that will be very humid, such as bathrooms, the webersys Protect Waterproof Tanking System may be applied over weberfloor Flex.

A thin layer of the weberfloor Level Floor Levelling Compound can be used on top of weberfloor Flex prior to the application of flexible floor coverings.
