How to Install

A Closer Look At How To Install Passive Purple Brush

With its fibre reinforced polymer technology, Passive Purple Brush can bridge gaps of up to 7mm – 10mm. ideally you want the structure to have as little gaps in as possible to save time and cost on materials. once all connections, joints, boards and penetrations are complete and located, simply use a firm paint brush to fill and seal over the gaps and joints. this alone will reduce air leakage an enormous amount leaving your final spray coat ”if required” the icing on the cake. With a filler style technique and putty like consistency, Passive Purple Brush is extremely easy and fast to apply with no surface or area a problem.
