Wall Application in Showers and Wet Areas

Developed for absolute workability, the wedi® system is easily applied directly to stud walls with wedi® fasteners (screws and washers with tabs). After the panels are secured and the seams are sealed, tiling may commence immediately. This means that a bare wall can be prepared, waterproofed and ready to tile in a fraction of the time required by traditional methods.

When applied to the wall, wedi® Building Panels may be fixed perpendicular or parallel to the framing, saving time and reducing the frequency of joints. The panel can be fastened simply into place with wedi® screws or nails and all panel joints butted tightly. The wedi® fastener is set right into the joint where the washer head presses both panel edges together and allows for the flush transition. If a waterproof installation is required, all joints and fastener points should be treated with wedi® polyurethane sealant or wedi® waterproof sealing tape.

Using only a utility knife, wedi® Building Panel is effortlessly cut and shaped.

A continuous 1/2” bead of wedi® joint sealant is applied on the foam edges of a wedi® Building Panel before another panel is joined by butting tightly.

Apply 1 wedi® fastener per every 12", with an extra fastener applied directly in the seam to provide a flush transition. On a ceiling, apply 1 wedi® fastener per every 6”. The washer heads are dimpled below the surface of the wedi® Building Panel.

All excess wedi® sealant is spread flat over all joints using a putty knife. Where needed, an extra bead of sealant is applied on top of the joints and spread flat. The joints should be covered a full 3/4” on both sides of the seam.

In dry areas, the seams can be treated with an alkali resistant fiberglass mesh tape by wedi®.

Alternatively, wedi® sealing tape can be used instead of the wedi® joint sealant and applied in modified thinset. The sealing tape provides adequate splash water protection but should not be used where standing water occurs because thinset might allow pressing water to migrate underneath the sealing tape through the thinset mortar.
