GMB Galvanised Movement Bead

GMB Galvanised Movement Bead

Designed to be used to form movement joints in plaster or render where long wall runs either have movement joints in situ or where there is a need to allow for differential or thermal movement. The bead consists of two plaster stop lengths joined by a white pvc extrusion which allows for up to 4mm of movement and which is covered by a vinyl tape which is removed after plastering or rendering. Internal use only. We recommend Stainless Steel or PVC-u for external rendering.
