Vara Fluid

VARA FLUID Spray is the airless-spray (or roller) version of Partel's liquid air and vapour control layer — built for production speed on commercial projects without sacrificing the hygrovariable performance of the brush version.

What it does

It dries to a flexible, airtight membrane that adapts vapour permeability to ambient humidity: more open in summer to release moisture, more closed in winter to prevent condensation. The wet film bridges cracks and gaps up to 2 mm and bonds to most building substrates.

When and where to use it

• Commercial projects where spray throughput is needed
• Internal and external wall, floor, and ceiling junctions
• Construction joints, wall-to-floor, wall-to-ceiling, wall-to-timber
• New build or retrofit on masonry, concrete, OSB, plywood, silicate

Key benefits

• phA Passive House certified, zero air permeance
• Variable Sd 0.15–16 m
• Class W1 water resistance
• Low VOC, water-based
• Applies to slightly damp surfaces
• Beige darkens on cure for coverage verification

Format
