Expandable PU Foam is a powerful expanding sealant that fills cracks, gaps, and hard-to-reach spaces with ease. It expands to many times its original size, creating a durable seal that helps block insects, dust, drafts, moisture, and noise. Once cured, it can be trimmed, sanded, and painted for a clean, professional finish. PU expanding foam is commonly used for sealing windows, doors, pipes, roof gaps, wall cracks, and other cavities.
