Specialty Applications – the wedi Building Panel as solution
Round and curved walls
Create a series of cuts into the wedi Building Panels 1/2” the thickness
of the panel deep. The distance between cuts depends on the tightness
of the radius needed later. Use a circular saw for these cuts. A wide
range of other shapes are possible using the wedi Building Panel. All
you need is a template shaped to suit your needs. A template may not
be needed for simpler shaping.
Cut the wedi Building Panel using a utility knife and straight edge. This
way wave shape constructions can be produced. For a small radius –
cut out wedges from the building panel or cut the wedi Building Panel
using a hand-held circular saw and bend it into a curve.

work the sealing tape flat over the seam and remove all air bubbles or
any other unevenness. Excess sealant is spread flat. Sealing tape inside
and outside corners, as well as collars for valves or other protrusions,
are available.
Cover all fastener/ washer points with wedi Sealant 620 covering an
area of 3” × 3” (76.2 × 76.2 mm) with the washer’s screw at its center.
Embed a sealing tape patch with a size of 2 1/2” × 2 1/2” (63.5 × 63.5
mm)
into the bed of wedi Sealant 620 and press flat using a putty knife.
Use wedi Sealant 620 and wedi Subliner sealing tape and sealing col-
lars to seal around protrusions and penetrations of the Vapor 85 in
the same method as using the same method as for applying tape and
fastener point covers.
Allow the wedi Sealant 620 to cure for at least 24 hours prior to setting
tile and 96 hours after its application before exposing the tiled instal-
lation to water and water vapor. On floor areas, consider wedi Fundo
Shower Systems or Subliner Dry sheet waterproofiong membrane when
working over mortar or screed surfaces (install in accordance to Subliner
Dry installation manual using wedi Sealant 620 in overlapping sheet –
or Subliner Dry tape covered seam connections).
Ensure all framing and structures meet applicable wedi general require-
ments, building code and industry standards. Attach Vapor 85 panels to
wall horizontally, and set the fasteners 1 ft. (304.8 mm) above shower
floor. Use wedi’s flat washers (washers without tabs) and screws. On
solid or wedi built bench constructions (1 1/2” [38.1 mm] to 2” [50.8
mm] wedi Panels) install wedi Vapor 85 panels in well distributed 1/2”
(12.7 mm) beads of wedi Sealant 620 spread with a space of 6” (152.4
mm) between beads. If the construction is not entirely smooth, use a full
thinset mortar bed to attach using a 1/4” × 1/4” (6.4 × 6.4 mm) trowel.
All panels are butted tightly with wedi Sealant 620 continuously applied
between all contact seams. Excess sealant is spread flat with a putty
knife. Use only wedi’s flat washers so the membrane is not twisted
upon tightening the washer. On ceilings, set wedi fasteners at a rate
of 1 per every 6” (152.4 mm) of framing. In addition, apply a contin-
uous 1/2” (12.7 mm) bead of wedi Sealant 620 on every stud before
attaching the panel.
Apply several beads of wedi Sealant 620 as a setting and sealing bed
for wedi sealing tape. Spread the sealant with a fine tooth adhesive
trowel or flat putty knife to achieve a full coverage sealant bed for
the sealing tape. The minimum thickness of the sealant bed should be
1/16” (1.5 mm). The tape is centered over the seams and pressed flat
into the sealant. Make sure to use a flat putty knife or paint roller to
