Facade weatherproofing, pure acrylate polymer breather membrane. Vapour Control Vapour
The product is applied to exposed facades as a protective membrane. Usually applied before the application of PASSIVE PURPLE® EXTERNAL, on gaps, joints, connections, service penetrations, corner junctions.
Passive Purple External Brush is a ready-to-use, façade membrane coating based on specific pure acrylate polymer dispersions. After application with an airless spray device or paint roll, the coating dries to a durable, flexible, watertight and damp-open membrane.
Passive Purple External Brush is a UV-resistant and watertight spray or roll-applied membrane used for facades. It is a Fire Class B, S1 product that can adhere to any form of construction.
A ready-to-use coating based on specific pure acrylate polymer dispersions, which after application with a paintbrush, dries to a durable, flexible, watertight and damp-open membrane.
For small projects, such as private houses, Passive Purple Brush, façade membrane can be used with a flat paintbrush. In this case, an airless spray device is not needed.
Wall/ceiling connections need to be made airtight, especially when the connections are made of two different types of construction materials such as red brick/concrete or steel/concrete. Different construction materials react differently to changes in humidity and temperature, moving at different rates, which can lead to small cracks in plaster or another type of finishing. That movement can create air leaks that cause your building’s energy performance to suffer and potentially open the gateway for damp and mould to appear.
Service penetrations can be the downfall of any air tightness testing. Passive Purple Brush façade membrane is applied around objects that penetrate any surface to the external envelope, sealing where most tapes and membranes fail. Before you apply Passive Purple Brush, first apply polyurethane foam around any penetrations. After hardening, remove the excess foam and apply a generous amount of Passive Purple with a flat paintbrush. In all cases, apply a sufficient, well-covering layer to guarantee airtightness.
Passive Purple Brush can be applied (and is tested) on different construction materials such as concrete, brick, wood, PVC, aluminium and polyurethane foam. With a coat of Passive Purple External Brush, the whole window/door reveal can be made airtight.
