ConFlex™ SherLastic® Elastomeric Coating is the economical choice for excellent protection from wind-driven rain and harsh weather conditions. Designed for use on vertical masonry and concrete surfaces, ConFlex SherLastic covers and hides hairline cracks while helping prevent water from penetrating into building interiors. ConFlex SherLastic is designed to not trap moisture vapor inside, reducing callbacks due to blistering. With smooth application, ConFlex SherLastic makes it fast and easy to achieve a uniform, pinhole-free finish, and with excellent efflorescence resistance, ConFlex SherLastic maintains its freshly coated appearance and reduces white salt surface staining. It delivers an attractive, uniform finish and waterproof protection at a great value. Flexible, 100% acrylic elastomeric formula helps bridge hairline cracks and minimizes pinholes.
