Vara Fluid Brush is a water-based vapour control coating providing continuous airtightness over cracks and gaps in both new build and retrofit projects.

Vara Fluid Brush is a water-based air & vapour control layer (AVCL) that can be brushed, providing a continuous airtightness over cracks and gaps in both new build and retrofit projects. Advanced Hygrovariable Technology allows incredible summer drying conditions, but can equally protect the construction in winter.

Features and benefits:

Innovative liquid airtight membrane that changes vapour permeability according to the ambient relative humidity (RH). This contributes to maximum protection in the building envelope where moisture levels are critical, allowing vapour to escape and dry the structure.
Ensures optimum moisture flow through building structures with a Sd range of 0.15m to 16m.
Hygrovariable Technology - Extremely safe airtight system.
phA Class Passive House Certified airtight system, featuring an air permeance value of 0.00 m³/(m²h)
Flexible and durable.
LOW VOC polymer-based liquid.
Class W1 resistance to water penetration.
Excellent adhesion on various surfaces .
Fast application – speeds up construction.
Ready-to-use product – vertical or horizontal application.
