Fields of application

weber.floor 4310 is used as self-levelling mortar and thin-layer screed for a wide range of floor substrates via manual or mechanical application. For use as heated or non-heated thin-layer screed. As bonded system on many substrates (e.g. concrete, screeds, ceramic tiles, timber substrates) and on underfloor heating elements (warm water tubes, electric and capillary tubes). Also, as unbonded system on separating membrane (natron kraft paper or PE-foil) and on underfloor heating elements (heat conducting metal plates)
Furthermore, as floating system on insulation boards and on acoustic membranes.
Ideal for levelling works of large surfaces as well as for quick refurbishment and renovation of old floors (concrete, screeds, ceramic tiles, timber substrates), It forms a sound, even, smooth and load-bearing substrate for all common flooring materials. For indoors.

Main features

• EMICODE EC 1PLUS: very low emission of volatile substances
• CE marking: CT – C20 - F7 (EN 13813)
• multi-use on most substrates
• suitable for all types of constructions: as bonded, unbonded and floating system, in different layer thickness
• very good flow performance
• normal-drying
• resistant under chair castors (in accordance with EN 12529), when used in a layer thickness ≥ 2 mm under flooring materials
• fiber-reinforced
• suited for machine application and pumping
• low (reduced) tension when hardening

General notes

• Assess the levelling requirements beforehand.
• For application on floating constructions and heated screeds, all walls and upstands (pillars, columns, etc.) within the floor should be separated with an 8-mm thick insulation foam strip; it must reach downwards from the substrate up to the upper edge of the final covering.
• Plan movement joints for surfaces > 40 m2; in case of side lengths > 6 m, the optimal ratio between length and width should be 2 : 1.
• Arrange dummy joints for special structural features, heating circuits and special room geometry, i.e. wall entry points, doorways, wall recesses. Take over existing movement joints.
• The final surface must receive a covering and cannot be left without.
• If used as a heating screed, request technical advice for tailored-made (special) solutions.
• Do not add any foreign substances during mixing and application.

Special notes

• Limits of use: only use indoors.
• In the case of floating constructions, the compressibility of the insulation boards must not exceed 3 mm.
