About This Product
Waterproof Sealant and Construction Adhesive
wedi® Joint Sealant is a single-component Silyl Modified Polymer (SMP) sealant and construction adhesive for waterproofing, bonding, and reinforcing joints, seams, connections, and fastener points. Its high green strength provides strong initial adhesion while maintaining permanent flexibility after curing.
Wet and Alkaline Environment Performance
The formula is engineered for waterproof adhesion and resistance to alkaline conditions found in wet thinset mortar environments. This makes it well suited for tile and shower installations where sealants may be exposed to moisture, mortar, and other demanding installation conditions.
Flexible Joint and Seam Treatment
Permanent flexibility allows the sealant to accommodate stress caused by shock, vibration, and thermal movement while maintaining a watertight connection. The single-component formula is solvent and isocyanate free and develops a skin after approximately 30 minutes.
Shower and Tile System Applications
wedi Joint Sealant can be used for waterproof sealing and bonding applications in shower and tile assemblies and is specifically approved for connecting wedi Building Panels and wedi Fundo® Shower System components without additional tape reinforcement when installed according to wedi instructions.
