Everbuild Foam Sealant Joint Backer Rod 10mm x 10 Metre

Product Information

Promotes an hour glass shape, this maximizes the bond area but keeps the depth of sealant consistent in the middle allowing for movement. Backer Rod is an integral component of sealant joints, it provides three main functions that allow the sealant joint to perform. The rod should be inserted into the joint, pushing it down until it reaches the bottom of the joint. So, to the missus disgust, all kinds of hairy critters and creatures slip in and are frequently founding feasting around the house.

Realising that they would needed to be stuck instead of screwed into place, I googled sealant and adhesive that would do the job. Backing rod for fire resistant joint sealing in horizontal and vertical building structure applications. The Backer rod limits the depth of the sealant, thereby preventing excessive use of the sealant, which promotes proper joint design. The everbuild foam gap filler backer rod sponge insulation is a purpose made material designed to seal properties and is used widely in the construction industry to seal joints to control sealant depth and create a backstop to allow appropriate sealant tooling.

Provides backing against which the sealant is applied, forcing the sealant to the sides of the joint for adhesion.

Because the sealant will not bond to the "skin" of the rod, it can stretch and recover with joint movement, with minimal stress being put on the points of adhesion to the substrate.It is inserted into a joint to control sealant depth and create a backstop to allow appropriate sealant tooling. The backer rod supports tooling so after installation of material the sealant can be pushed to the bond line with a spatula, ensuring wet-out of the sealant to the substrate.
