wedi Joint Sealant is a flexible sealant and construction adhesive that creates strong and waterproof connections between wedi assembly parts without additional tape reinforcement needed. It is used to join and waterproof between wedi products where they connect, and over the seams of these connections.
Additionally, wedi Joint Sealant is applied over fastener penetrations/points. wedi Joint Sealant is a single component Silyl Modified Polymer (SMP) for use in wedi product system installations as specified in installation manuals. The product is especially formulated for high green strength (high immediate internal strength), adhesion in wet and alkaline environments, and permanent flexibility. The product forms strong connections between wedi components and provides watertight seals on and in joints and seams, and allows for dissipation of stress caused by shock, vibration, or thermal movement.
