Morphology
The meaning 'a substance used to seal joints or fill cracks' is directly and transparently derived from combining 'sealing' (relating to making something watertight or closed) with 'material' (a substance). This modifier+noun composition follows a common lexical pattern found in many languages, so a B1 learner who knows both constituents would readily infer the MWE's meaning.
Etymology
Sealing material comes from the simple image of sealing—like putting wax on a letter or filling a crack so water cannot get through—and material meaning a substance. That's why sealing material means a substance used to close joints or fill cracks to stop air or water from leaking.
