Mighty SealTM is a single component, high performance, gungrade, acrylic urethane elastomeric sealant. Formulated with premium technology, it reduces dirt pickup, eliminates yellowing and “shiners.” It requires no priming to bond to most materials, including concrete, wood and masonry. It has superior adhesion and durability, 50% total joint movement and 800% elongation. Mighty SealTM forms an airtight, water resistant seal, and once cured, the bead is mildew resistant. Mighty SealTM has excellent UV resistance and will not discolor.
