Costar Expanseal 300
Costar Expanseal 300 is a self-leveling polyurethane sealant ideal for horizontal applications that allows continual movements of the structure caused by thermal changes without cracking. When the Part A and B components are mixed together leads to a chemical reaction, which cures to a firm, flexible rubber like seal with excellent adhesion to concrete, masonry, wood, glass, acrylic, stone, metal and many other common building substrates.
