Description

The Control Joint Bead eases the stresses of the basic expansion and contraction associated with inherent shrinkage during stucco curing stage of the cement stucco (generally exterior or gypsum plaster interior) coats and minor thermal expansion and contraction.
The product is available in standard length form but with varying depths, which is necessitated because of the wide depth of plastering requirements it is involved in. Movement bead consists of two lengths of stop bead linked with a white PVC extrusion.
Movement bead allows +/- 3mm differential expansion or settlement movement between adjoining surfaces.

Applications

Designed to deal with normal initial stucco shrinkage during the hydrating and curing stage of the portland cement stucco coats and minor thermal expansion and contraction.
Provides clean, neat edges to 2 coat plaster and render work at opening or abutments onto other wall or ceiling finishes. Ensuring protection against chips, cracks and impact damage.

Advantages

Many advantages could be cited here over and above the existing products.
1. Plastering finish at expansion joints looks very neat and straight, thereby enhancing the aesthetic looks.
2. Provides perfect sealing at the joints there by stopping water seepages through the joints.
3. Minimum quantity of epoxy sealant is used thereby cutting cost.
4. Reduces the wastage of time while working with joints, and speeds up the pace of work.
