Sealants are widely used for sealing gaps and various mounting clearances. Their pasty consistency makes it easy to squeeze the substance out of the tube. Bottles with a thin spout facilitate delivery to hard-to-reach places. The basis of the sealant is a composite or polymer, and the solvent provides hardening after its evaporation. The rating of the best sealants will help to understand popular products for sealing joints when installing doors and windows, waterproofing threaded connections, sealing joints and gaps during repair work.

Best polyurethane sealants
These are waterproof and noise-suppressing materials for sealing joints and mounting clearances. They are made by a mixture of elastomer with various additives, expanding from the interaction with air and forming a dense foam mass. Polymers are not prone to the formation of fungus and plaque, but are destroyed by sunlight.
