wedi® Sealant 620

Product information

wedi® Sealant 620 is a flexible sealant offering vapor-tight performance. It is used with a wedi sealing tape to create strong connections in wedi® Subliner Dry Sheet waterproofing and wedi® Vapor 85 assemblies.

wedi® Vapor 85 steam shower installations are installed using the wedi® Sealant 620 between assembly components. Used to waterproof and affix wedi sealing tape over seams and fastener points. For use with all wedi® Subliner Dry products (includes wedi Inside/Outside Corner Sealing Tape, wedi waterproof sealing tape, wedi Vapor 85 patch kit for fastener locations, and wedi® Subliner Dry mats for seams and overlaps.

**Note: Thinset mortar is also used in the installation of wedi® Subliner Dry. See installation instructions for more information.

wedi® Sealant 620 is necessary to use in combination with wedi® Vapor 85 and wedi ®Subliner Dry. wedi 620, unlike wedi Joint Sealant, is not a standalone construction adhesive. Where wedi® Sealant 620 is used to adhere, connect and seal assembly parts, it needs to be used in combination with wedi® Subliner Dry sealing tape reinforcing all seams and joints.
