They share similar aerosol tube packaging and are both widely used to handle wall and frame gaps, yet their chemical compositions, core functions and applicable scenarios are completely different. Many new contractors, DIY renovators and building material distributors often mix up filling and sealing functions, which leads to poor insulation, water leakage, mold growth and short service life of sealing projects.
