The GSK Backer Rod is a chemically inert, flexible material designed to serve as both an insulation medium and a bond breaker. It prevents three-side adhesion between the sealant and substrate, ensuring proper joint design and extending the life of the sealant application.
Ideal for use in construction and sealing projects, the backer rod helps control the depth of the sealant, provides a firm backing for tooling, and improves the efficiency of sealant use. Its lightweight, non-absorbent, and durable composition makes it suitable for a wide range of building applications.
