Components:
- Primer/ Bonding coat (weberfloor 4716 primer):
- Mesh reinforcement (weberfloor 4945 - not for use with underfloor heating):
- Base screed (weberfloor fibre rapid 4320 - for use where required):
- Damp proofing membrane (weberfloor DPM - for use where required):
- Sound insulation (weberfloor 4955 dB - for use where required):
- Top layer topping screed (weberfloor smooth rapid 4160):
Weber will only guarantee the products which form the system. Where membranes/ DPM by others are used, these will require a guarantee by the membrane/ DPM manufacturer.
Please ensure movement joints coincide with the building and can be used to assist with sequencing of application.
Preparation/ Recommendations:
Please note that weberfloor fibre 4320 and 4160 should not be painted or used without a floor finish.
Consult manufacturer's literature for specific mixing instructions.

Primer/ Bonding coatThe substrate should be vacuum cleaned, prepared and primed with weberfloor 4716 primer, according to the manufacturer's instructions (e.g. mixing recommendations). Priming improves the screed’s adhesion to the substrate and prevents the formation of air bubbles and dewatering of the screed. Dry and very porous substrates (cast-in-situ concrete floors) may need to be treated twice. If the screed is applied in more than one layer, each layer must be primed. | weberfloor 4716 primer. Minimum of two coats. Coverage:
|
Base screed | weberfloor fibre rapid 4320.
|
Damp-proofing membrane (DPM) | weberfloor DPM. For a fully bonded construction.
|
Sound insulation | weberfloor 4955 dB. Edged must be fully sealed, otherwise joint adhesive tape weberfloor 4970 may be required.
|
Top layerDomestic and commercial thin coat topping screed, to be applied to a maximum thickness of 30 mm. Consult manufacturer for further details. | weberfloor smooth rapid 4160. For use prior to the overlay of flexible floor coverings such as vinyl or linoleum.
