Sealant is a material used to fill gaps, cracks, or joints in surfaces to prevent air, water, or other substances from leaking through. It is commonly applied in construction, plumbing, or automotive repairs to ensure a tight, waterproof, or airtight seal. Sealants are usually flexible, allowing them to expand or contract with temperature changes without cracking. They come in various forms, such as liquids, pastes, or tapes, and are often made from materials like silicone or rubber. Sealants are important for maintaining energy efficiency and preventing damage from moisture.
