sealant
Crack-blocking compound
Sealant is a substance used to block the passage of air, water, or other materials through gaps, joints, or porous surfaces.
Common sealants include caulk around bathtubs, silicone around windows, and rubber compounds for tire punctures.
Unlike adhesives, sealants primarily prevent leakage rather than bond materials together, though many do both: Apply sealant around the edges before installing the window.
