Backer Rod 5/8" Hot Rod Red

HOT ROD XL is an ideal compressible and non-absorbent backup material that is inserted into a joint to control sealant depth. This creates a backstop to facilitate accurate sealant tooling and proper sealant wetting of the joint surfaces, yielding a quality bond breaker between the backup material and the sealant. HOT ROD XL can also be used as a temporary joint seal.
