Description
Siramiguard Vapour Barrier is a fiber reinforced polymer membrane for vapour barrier over construction-based substrates. SIRAMIGUARD VAPOUR BARRIER is a waterbased (VOC Free), single component, sprayable Vapour Barrier Membrane (VBM) formulated to provide a seamless weather resistant protective membrane which provides a flexible film allows expansion and contractions of substrates during low and high temperature weather cycles, good UV resistance with a durable polymeric finish. Elastomeric polymeric film primer-finish.
Intended applications
Can be applied over common porous surfaces in construction builds. Also suitable for concrete / cementitious substrates. Can be used over joint sealants and expanded foams. The polymer coating can withstand crack bridging up to 5mm.
