Fields of application

weber.floor 4491 turbo is used as fast-drying screed on separating membrane, on insulation boards, on underfloor heating and on hollow space floors/raised floors in residential and commercial constructions and in office areas.

Main features

• EMICODE EC 1 PLUS: very low emission of volatile substances
• CE marking: CA - C30 - F5 (EN 13813)
• with flow performance
• low tension and low shrinkage during setting
• allows large working sections up to 200 m²
• ready for overlay with flooring materials after 7 days
• reduces building moisture
• suitable on underfloor heating
• open to light pedestrian traffic in very short delay

General notes

• Follow the national guidelines/standards; if not issued and if necessary, refer to the norm DIN 18560 (relating to the load-dependent thicknesses for calcium sulphate flow screeds).
• Arrange dummy joints for special structural features and special room geometry, i.e. wall entry points, doorways, wall recesses. Take over movement joints.
• Seamless surfaces of up to 200 m² can be installed; the optimal ratio between length and width should be 2 : 1.
• Pay attention to separated heating circuits; expansion joints must be installed between separately geared heating circuits and cold-hot zones.
• For application on floating constructions, walls and any upstands (pillars, columns, etc.) within the floor should be separated with a thick insulation foam strip ≥ 10 mm; it must reach downwards from the substrate up to the upper edge of the final floor covering.
• For side lengths > 8 meters, a double edge insulation foam strip must be installed.
• In case of doubt regarding application, substrate or special structural features, request technical advice.

Special notes

• The product develops heat during the setting process.
• The use of pouring trestles is not permitted.
• In case of use of large-format strip parquet (> 30 cm) or solid parquet with a high risk of dimensional change is to be laid and if no MS adhesive (weber.floor 4830) or if no 2-comp. PU adhesive (e.g. weber.floor 4838) is used, the 2-comp. epoxy primer weber.floor 4712 (EC 1) must be applied as an intermediate coat.
• In case of rising damp, apply 2 coats of epoxy resin as vapour-barrier, e.g. weber. floor 4712 (EC 1) directly onto the concrete substrate with silica sand spreading over the fresh second coat.
• Do not add any foreign substances during mixing, pumping and application.
