SQUARE FOAM ADHESIVE CAULKING STRIPS 40mm x 40mm x 2m (100m per pack)
Description
Square foam caulking strips (also known as a backing rod) are a compressible and conformable polyethylene foam extrusion measuring 2 metres long. Used as a backing for sealants in expansion/construction joints, it is easy to compress and provides a stable base for building sealing applications. The foam cell structure helps facilitate curing of the sealant, and being made from flexible foam it is easy to cut and shape to various sized joints. They ensure a tight seal to prevent dirt and water entry into the structure, and are compatible with most common building sealants, silicones, gap fillers and foams.
