Hercules® Plastic Seal™ is a multi-purpose, extremely durable polyurethane sealant. Works with or without oakum. Single component polyurethane sealant that cures rapidly to a firm yet flexible, waterproof and weather resistant seal. Multi-purpose repair product can also be used for caulking the perimeters of frame openings, ductwork, wood or masonry expansion joints and for glazing both inside and out.
