Fields of application
weber.floor 4190 is used as height compensation for different substrates in the renovation of floors in residential and commercial constructions. For thin-layer warm water underfloor heating systems (bonded system) with a covering of heating elements by ≥ 10 mm. Also, as topping screed for domestic bathrooms and basement rooms with appropriate waterproofing, but not for wet-duty rooms. In all cases, it forms a load-bearing substrate for all common flooring materials.
For use indoors.
- EMICODE EC 1PLUSs: very low emission of volatile substances
- CE marking: CA - C30 - F6 (EN 18183)
- fits mechanical mixing and application well
- high flow performance
- resistant under chair castors when used under flooring materials
- low shrinkage and low tension during setting
- very suitable for calcium sulphate screeds and mastic asphalt screeds
- cost-effective for large areas
- heatable after only 6 hours
- Assess the levelling requirements beforehand.
- Arrange dummy joints for special structural features and special room geometry, i.e. wall entry points, doorways, wall and recesses. Take over existing movement joints.
- Ensure that application fields do not exceed 60 m2; the optimal ratio between length and width should be 2 : 1.
- For application on floating constructions and heated screeds, all walls and up stands (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.
- The final surface must receive a covering and is not allowed to be left without.
- In case of doubt regarding the application, substrate or special structural features, request technical advice.
- Do not add any foreign substances during mixing and application.
- Limits of use: only use indoors.
- For installation in thick layers, a maximum slump of 230 mm (4.0 - 4.25 liters of water per 25 kg bag) is recommended.
- For installation on thin-layer warm water underfloor heating systems (bonded system), the slump should not be set below 240 mm (4.5 - 4.75 liters of water per 25 kg bag).
