Some caulking joints are larger than others and tricky to seal.  For these situations Paint Supply offers a wide selection of caulking backer rod in a variety of diameters and lengths, allowing you to seal larger joints with less caulk.

Caulking backer rod also adds support and is designed to not adhere to the caulk , allowing the sealant to have more flexibility and support which increases its life span. Fill large gaps around doors, windows and foundations with our selection of acrylic caulk, polymer and urethane sealants, elastomeric sealant, and silicone sealants.  Make professional joints that last with right size and quality of backer rod!
