Movement Joints (Expansion Joints)

Our PVC movements joints and expansion joints are specially designed to be fast and easy to cut and fix on all walls that have textured render coatings, spray render and acrylic render finishes on masonry, cement board or insulation board such as expanded polystyrene. PVC movement beads and trims expand and contract with the structural movement joint thus reducing cracking and the finish looks great.

Application

We recommend that movement joints or expansion joints must be used where there is a structural movement joint under the render and in cases of a change to the background substrate. PVC movement joints and expansion joints may be used horizontally as a day joint or to define different coloured rendered panels.

Packing

Our range of PVC movement joints and expansion joints come in the following packs:

25 no x 2.5m lengths in fibreboard boxes.

25 no x 3.0m lengths in fibreboard boxes.

Fixing

Use a line of render dabs which can be simply applied or mudded on to the substrate. If mechanical fastenings are used to fix PVC movement joints and expansion joints, these must be stainless steel when using the beads outside. If fixing a MJ10 movement joint or expansion joint with nail clouts, ensure care is taken to not distort the PVC beads out of shape. We recommend that butt joints are embedded in silicone mastic to prevent water ingress.

Colours

Currently Renderplas PVC movement joints and expansion joints are available in Australia in a cream colour called Sand. Upon request corner beads are available in a further twelve colours (White, Ivory, Brick, Terracotta, Wheat, Peach, Salmon, Maize, Slate, Dove, Sky, Willow).
