Renderplas PVC movement joint beads were critical components in the successful rendering of Treliske Retail Park in Truro, Cornwall.

Bruce Clarke of Somerset Plastering, who undertook the 1,300m2 render refurbishment; “The use of movement joint beads should be considered on all rendering projects.

“Buildings move over time and the rendered surface is no different. Whether the sun is shining on an aspect or freezing rain is lashing against it, render will continually expand and contract.”

The specification and installation of movement joint beads is essential if a rendered surface is to survive and maintain its clean, crack-free look. Movement joint beads allow room for the render to expand and contract without cracking.

Renderplas movement joint beads are guaranteed for a minimum of 25 years or for the life of the render, so their use can significantly reduce the need for expensive maintenance.

Movement joint beads can also become a design feature by creating definition lines that enhance the aesthetic of the building.

Bruce Clarke went on to say: “In the case of Treliske Retail Park, it meant we could create a perfect pinstripe between the K Rend Limestone White and Granite render at the bottom of the wall, which looked great.”
