Everbuild Tecnic Joint Backer Rod 25mm x 200mtr

Everbuild Tecnic Joint Backer Rod 25mm x 200mtr is a non‑absorbent, compressible, closed‑cell polyethylene foam rod designed to control joint depth and optimise sealant performance in construction, glazing and façade applications. This everbuild tecnic joint backer rod 25mm x 200mtr is inserted into a joint to create a reliable backstop, ensuring the sealant forms the correct hourglass profile and preventing three‑sided adhesion, which is essential for movement capability and long‑term durability.

The 25mm diameter makes it suitable for larger movement joints, expansion joints and façade interfaces where deeper cavities require stable backing. Its closed‑cell structure prevents moisture absorption and provides excellent resistance to chemicals commonly encountered in building environments. The rod is flexible, easy to compress and simple to install, supporting efficient workflows for professional contractors.

By controlling joint depth, Everbuild Tecnic Joint Backer Rod 25mm x 200mtr reduces sealant consumption, improves joint aesthetics and enhances overall sealant performance. It is widely used in masonry joints, cladding systems, glazing interfaces and general construction sealing tasks.

How to Apply Everbuild Tecnic Joint Backer Rod 25mm x 200mtr

• Surface preparation — ensure joint surfaces are clean, dry and free from contaminants
• Rod selection — choose a diameter slightly larger than the joint width for secure compression
• Insertion — press the rod into the joint to the required depth using a blunt tool
• Sealant application — apply sealant over the rod, ensuring full contact with joint sides only
• Finishing — tool the sealant to achieve the correct hourglass profile
