GMB Galvanised Movement Bead
Locusrite
Price not listed
Plaster and render 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. The 108mm overall mesh wing allows for a good plaster key and resistance to cracking. Fixed by plaster or mortar dabs, grab adhesive or galvanised nails/screws
