Colors
Product features
- without biocides, without film preservation
- hydrophilic surface with balanced moisture management, preventing the formation of algae and fungi
- creates a healthy living climate through optimal water vapour permeability
- high protection against driving rain (exposure class III with rainfall over 800 mm according to DIN 4108)
- for mechanical and manual application
Product advantages
- without biocides, without film preservation
- hydrophilic surface with balanced moisture management, preventing the formation of algae and fungi
- low tension when hardening
weber.star 261 AquqBalance is mineral lightweight top render used for indoor and outdoor use as a finish top coat on the insulating render on weber.therm ETICS (external thermal insulation composite systems) and weber.dur underlay renders (base coat). weber.star 261 AquaBalance is particularly suitable for fine-grained individual, classic and modern textures, such as broom render, comb render, trowel render and country house render.
