External Detailing Kit for Airtight, Weatherproof Facades
Detailing an external facade airtight and weatherproof means having the membrane and the tools to hand — not stopping mid-junction to source bits. An external detailing kit keeps the work continuous.
The problem
Piecemeal buying leads to missed items and inconsistent external detailing — exactly where the weather will test your work hardest. On a facade, a gap at a reveal or penetration is a direct path for wind-driven rain and air.
The solution: the External Brush Pack
The Passive Purple External Brush Pack brings together brush-applied Passive Purple External with what you need to detail junctions, reveals and penetrations to an airtight, weatherproof, vapour-open standard — in one kit.
What it covers
- Corners, reveals and parapets
- Penetrations and service entries
- Transitions to windows and doors
- Tie-ins to the main sprayed membrane
Benefits
- Everything for external detailing in one pack
- Airtight, weatherproof, vapour-open
- Fibre-reinforced brush membrane
