wedi Sealant 620
wedi Sealant 620 is based on the same basic design as the wedi Joint Sealant but is modied to perform best in steam
showers due to its vapor resistant t with our Vapor 85 and Subliner Dry
®
surfaces. wedi Sealant 620 is a exible sealant
offering vapor-tight performance. It is used with a wedi sealing tape to create strong connections in wedi Subliner Dry
®
Sheet waterproong and Vapor 85 assemblies. It is used for wedi Vapor 85 steam shower installations. They are installed
using the wedi 620 Sealant between assembly components. Use to waterproof and afx 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 indispensable in combination with wedi Vapor 85 and wedi Subliner Dry
®
. wedi
620, unlike wedi joint sealant, is not a standalone construction adhesive. Where wedi 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. In a wedi 620 installation project with wedi Subliner
Dry
®
waterproong membrane you need one 2.5 oz per every 1 linear foot of wedi sealing tape
or Subliner Dry
®
overlap seam coverage in a wedi Vapor 85 (includes fastener points treatment) or
Subliner Dry
®
assembly.
wedi Joint Sealant
wedi Joint Sealant is a product designed by wedi to meet our shower system performance needs. wedi Joint Sealant
is a exible sealant and construction adhesive that creates strong connections between wedi assembly parts without
additional tape reinforcement—used for standard wedi shower installations with the wedi Fundo Primo, Fundo Ligno,
and Fundo Riolito.
wedi Joint Sealant is indispensable in regular wedi shower assemblies to adhere, seal and
reinforce seams and connections and waterproof fastener points. No additional taping is
needed! wedi Joint Sealant is a single component Silyl Modied Polymer (SMP) for use
in wedi product system installations as specied in installation manuals. The product is
especially formulated for high green strength (high immediate internal strength), adhesion
in wet and alkaline environments, and permanent exibility. 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. It is used to waterproof, connect and reinforce seams or fastener points. For
an average wedi shower installation, you’ll need to plan for approximately 1.2 oz per one
square foot of wall panel surface in your shower.
