Fields of application

weber.pas 431 is used as overlay render (top coat) for outdoors on weber.dur underlay renders (base coat) and as finish top coat on all weber.therm Etics systems (external thermal insulation composite systems).

Main features

• water-repellent
• resistant to high mechanical loads
• very good adhesion to all substrates
• highly elastic
• weather-resistant
• solvent-free
• decorative floated finish with a grain-to-grain texture
• fulfills all requirements of the norms EN 15824 and DIN 18550, part 1 for organic renders

General notes

• Material dries by evaporation of water. Therefore, damp weather will delay drying. Complete drying may take up to 2 weeks.
• During application and drying, the temperature of air, materials and substrate must always be above +5 °C and the relative humidity rate must be below 80 %.
• Protect fresh render surfaces from direct sunlight, strong winds or moisture.
• For application and design follow the national guidelines/standards; if not issued and if necessary, refer to the norms DIN 18350 VOB/C and DIN18550.
• The consumption figures mentioned in this document refer to the minimum layer thickness of the render. Due to specific substrates and application variations the consumption might vary. Exact consumption must be determined on a job site mock-up (trial area).
• Adjacent building parts must be separated from the built-in render system.

Special notes

• After drying the render colour might vary due to natural deviations of raw materials, render structure as well as application and drying conditions. For the same reasons the render colour might deviate from the Weber dry sample or colour chart. Colour variations cannot be considered as quality loss or as justified claim.
• If possible, order the whole material quantity for the building site in one. If any buckets with different batch numbers, mix them with one another.
• The product is algicidal and fungicidal since it contains biocides for film preservation. Use biocides safely. Always read the label and product information before use.
• We recommend biocide-free products with AquaBalance technology for very high and durable protection against algae and fungal growth.
• Permanent high humidity level and dirt deposits for ex. in cases of application on socket areas of facades, faulty drainage and planting of trees close to buildings can promote the formation of fungi and algae.
