This plastic Bellcast bead is intended to be used with scratch/monocouche system. It is 2.5m in length and the profile is 14mm.
A 6mm Bellcast bead is also available to be used with thin coat render systems.
The Bellcast has 2 purposes, the first is to create a neat clean finish at the bottom of the render system where the render finishes. The second purpose of the Bellcast bead is to produce a drip to ensure that water running down the face of the render doesn’t then run down the wall where the render finishes – this helps prevent water penetrating the external walls building and causing damp.
