AEROVAP BRUSH is a high-technology water-based fibre-reinforced polymer paste that can be applied to various substrates using a broad brush and that, when dry, forms a very flexible, elastic and airtight vapour barrier membrane. It was designed for making various architectural joints airtight, such as the joints between floors and walls or between walls and ceilings, openings for pipes, etc. Applied as a veneer plaster, AEROVAP BRUSH is also suitable for rendering unplastered masonry walls airtight (lift shafts, garage walls, exterior walls of school buildings, etc.). The surface to which AEROVAP BRUSH is applied must be porous (remove any hanging elements), dry and free from oil, grease and dust. Any cracks or large openings should be sealed before applying. AEROVAP BRUSH is dark blue in colour but this colour darkens after hardening. Any painting or replastering required can be done as soon as AEROVAP BRUSH has hardened. AEROVAP BRUSH can be applied to slightly damp substrates. Never apply AEROVAP BRUSH to frozen surfaces and do not use at temperatures below 5°C. To ensure an optimum layer of sealant, we recommend that you apply two coats of AEROVAP BRUSH. AEROVAP BRUSH can also be used as an etch primer on all porous substrates for adhesives in the AEROTAPE and AEROCONNECT ranges. It can also be applied as an adhesive for fixing AEROVAP, AEROMAX and AEROPLUS membranes to porous substrates (for this use, apply an initial coat to the substrate, smooth the membrane over the paste, then apply a second partial coat to the membrane and the substrate).
