  • Thickness: 15mm, 20mm
  • Material: Open-cell PU (Polyurethane) foam

Application

Placed as backfilling in horizontal and vertical connection and expansion joints before applying the joint sealant.

Open open-cell PU backer rod is ideal for joints of varying widths.

Suitable for use with cold-applied sealants such as silicones, polyurethanes, hybrid polymers, acrylic sealants,...

Method:

Before applying the backer rod, the joint must be prepared as prescribed by the sealant manufacturer. Apply PU backer rod compressed in the joint. Use the correct diameter to prevent movement in the joint. Diameter of the backer rod should be up to 50% larger than the joint width. Apply backer rod evenly to the desired depth (see sealant manufacturer's instructions). Do not apply the backer rod with a sharp object. Make sure there are no breaks between the different pieces of backer rod and that they fit properly.
