Fields of application

weber.star 221 AquaBalance is used as overlay render (top coat) for indoors and outdoors on weber.dur underlay renders (base coat).
Also, as finish top coat on the insulating render weber.therm and on weber.therm Etics (external thermal insulation composite systems).
For use indoors and outdoors.

Main features

• without biocidal film preservation
• without preservatives
• hydrophilic surface with a balanced moisture management
• excellent and durable protection against the formation of algae and fungi
• high protection against driving rain (exposure class III with rainfall over 800 mm according to DIN 4108)
• weathering-resistant
• creates a healthy living climate thanks to its optimal water vapour permeability
• extremely white appearance
• noble and granular floated finish with a stippled grain-to-grain texture
• for mechanical and manual application

General notes

• Protect fresh render surfaces from direct sunlight, strong winds or moisture.
• Comply with the national guidelines and/or standards (for ex. DIN 18550); if not issued and if necessary, request technical advice.
• 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 texture 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.
• In case of colour variations due to application and drying conditions, apply the egalizing paint weber.ton 414 AquaBalance (one off-rolling coat) in order to even out any differences in the shade of the render surface.
• In case of over-painting top renders, it is always recommended to use paints with AquaBalance technology (for ex. weber.ton 414 AquaBalance).
• 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.
• Thanks to its optimized moisture management weber.star 221 AquaBalance offers a 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 algae and fungi.
