wedi Vapor 85 for Steam Rooms and Steam Showers
A special variant of the wedi Building Panel, wedi Vapor 85 is designed for the specific installation in steam showers
and steam rooms. It will serve as a strong vapor retarder, by far exceeding the minimum requirements set by the Tile
Council of North America (TCNA) for vapor retarders used in continuous use steam rooms. At the same time it offers
all the benefits of the traditional and time tested wedi Building Panel: it’s light yet strong. It can be cut and worked
with in a clean and exact way. It adds insulation, and provides great bond for tile and other suitable surface finishes.
However, the best feature is that it is a component of a fully functioning system which was developed to also vapor
-
proof seams, and fastener penetrations. The wedi Vapor 85 makes best use of wedi system technology taken from wedi
Building Panel, wedi Subliner Dry, wedi Subliner Dry Sealing Tape, and wedi Joint Sealant. Additionally, it works great
with wedi Fundo or Subliner Dry on steam room floors.
wedi Sealant 620 is a moisture curing sealant remaining very flexible even when cured. In dry air or colder environments, the curing time may extend up to 24-48 hours, also depending on the amount used
and sandwiched between waterproof surfaces (tape/ wedi Vapor 85), allow for extra time before tiling and grouting with epoxy mortars and/or using tile larger than 12 in. x 12 in. The extended curing times
prior to exposure to water or water vapor are added. In the average steam room project, please plan for a consumption of (1) 20 ounce sausage for every 24 sft. of wedi Vapor 85 panel surface installed.
