information

Masons PEF Rod is a cylindrical flexible closed-cell polyethylene material, available in various diameters from 6mm to 50mm.

Suitable for domestic and commercial applications where gaps need to be sealed in conjunction with sealant or chalking compounds.

Key Benefits
  • Limits the amount and depth of the sealant applied to the joint.

  • Acts as a bond break to allow joint movement without undue stress to the sealant.

  • Acts as a barrier to the flow of sealant through a joint.

  • Will assist in providing an around-the-window frame and penetrations through walls.

  • For use with pre-cast concrete slabs and joints between brick and masonry.

  • Easy to install, non-toxic, and CFC-free.

  • No water absorption.

Scope of Use

Suitable for domestic and commercial applications where gaps need to be sealed in conjunction with sealant or chalking compounds. Always allow PEF Rod to be 25-30% larger than the width of the gap requiring the filling. Ensure that the rod is firmly in place.

Installation and Storage

Cut the PEF Rod to the required length and press the into the gap with a blunt tool to provide an even depth, avoid stretching and twisting the PEF Rod. Masons™ PEF Rod is not intended in areas exposed to sunlight.

Masons™ PEF Rod should be kept clean and dry during installation.
