11. Use the shorter Phillips head self-drilling screws with wings provided by wedi to fasten C brackets to the edge of the wood
subfloor at the open side of the shower area. Fit the brackets between flanges of the joist/wall brackets. Use two screws
to fasten this bracket through the wood floor and into the lower claws.
12. Measure and mark to cut wood strips to fit the recess bracket support system between joists, being sure to leave 1/8 in.
gap between strips and brackets. The gap allows for expansion of wood without creating undo tension.
13. Cut the wood floor strips. Additionally, cut the strip for the drain area and include a 6 1/2 in. diameter hole that will be set
over the center of the floor waste pipe.
14. Clean and degrease the bracket support flanges/surfaces and apply a 1/4 in. bead of wedi Joint Sealant. Use wedi Joint
Sealant, or a construction adhesive suitable for metal and wood application.
15. Place all wood strips into position on the brackets.
16. Secure the wood strips to the C and Joist brackets using the shorter Phillips head self-drilling screws with wings as provided
by wedi. Fasten, at minimum, every 10 inches where joist brackets are present, or where C brackets are in-line along the
framed wall and parallel to the floor joists. Fasten wood into all other C brackets with a minimum of two screws where
singular C brackets are mounted between floor joists on wall framing or wood floor transition side.
When the joists are parallel to the shower entry, the transition to the recessed
floor needs to be placed on the front ( the edge of a joist adjacent to the
recessed part) edge of floor joist regardless of final placement of the sloped
shower base placement. This means at times the recess needs to be extended
past the intended shower base space. It is important that the transition of
the non-recessed subfloor panel is fully supported by the floor joist. The
additionally resulting recessed space not covered by the shower base can
be filled in with plywood in a thickness needed to create a flush transition
floor area. The entire transition area is the waterproofed with wedi tile
underlayment connecting or overlapping into the shower base (either wedi
Subliner Dry or a wdi Building Panel with a sealed notch connection to shower
base channel.)
