wedi 610 - Adhesive sealant

Product information

wedi J610 is a low V.O.C ( <1%) variety component, Modified Silane MS Polymer that chemically reacts with moisture to deliver strong, flexible and tenacious bonds to variety of surfaces. Especially formulated to connect and seal wedi assemblies in their typically challenging application environment. The product forms water-tight seals on joints, seams and at installations and protrusions creating possible escape opportunities for water or water vapor ( i.e. shower valve cut out in waterproof wedi wall Building Board in shower installation). Its flexibility allows for dissipation of stress caused by shock, vibration, or thermal movement.

Particularly in comparison to traditional sealing tape and reinforcing mesh solutions applied in thinset mortar, the wedi 610 performs better in terms of water protection and stress and movement protections. Thinset mortar bonded tape applications will naturally allow water to migrate below the tape while wedi 610 seals to surfaces without the thinset mortar as an absorbing layer in between. Where assemblies are exposed to normal movement, traditional thinset bonded tape or mesh can only protect or add reinforcing strength up to the performance of the thinset mortar embedding it. If the thinset mortar fails, and they are not designed a crack isolation products, the tape will naturally fail with it.

wedi 610 with its direct and tenacious adhesion, yet an elongation potential of 220% provides added protections against movement. The same formulation of product was originally formulated , and is today used to seal assemblies in US military vehicles utilized in difficult terrain and exposed to sudden shock and vibration. On this basis, wedi added specific performance attributes to benefit the wedi installation performance.

However, if movement or settling exceeds what a typical tile as the surface finish can tolerate as per ANSI 118.12, which is exposure up to 2 mm, no sealant or tape or even shower liner can protect. It is therefore imperative to follow structural building codes (IRC and IBC) to install tile and underlayment product only over structurally sound and service condition acclimated ( wood) and cured ( concrete) substrates. Excessive movement may be tolerated initially as long as the substrate regains its original setting ( no excessive permanent settling can be protected against). The wedi 610 is of high viscosity and exhibits excellent non-sag properties.
