wedi’s pre-sloped shower bases Riolito neo feature fully factory sealed and integrated linear drainage systems. The base itself is naturally waterproof as well as mold proof, due to its closed cell XPS foam core. The Riolito neo bases come with the wedi typical strong and ready for tiling surface coating. All Riolito neo shower bases can be field modified. They can be cut to size or extended using wedi's pre-sloped Fundo extensions. The integrated drain in Riolito neo ensures your installation is not exposed to the risk commonly associated with bonding flange design/surface waterproofing installation-type, single drain products. The unique wedi Fundo Riolito neo bases allow water to drain away through a narrow gap between their drains cover plate and the tile surface finish. wedi Fundo Riolito neo is always equipped with the drain unit but covers are ordered separately. Options for covers include a polished stainless steel version, a double plated brushed stainless steel version, and a tileable version. Available in 4-way and 2-way or single slope designs with close to the wall drains, wedi Riolito neo features the industries only factory sealed drain for use in custom shower configurations. What is more, the Fundo Riolito neo is available in one piece shower base boards or as a modular system offering a separate drain module and an extension module to combine and configure custom layouts even easier.
Cut DN 50 pipe minimum 70 mm below the top of the Subfloor. Use the oval shape cutting template to cut subfloor using a jigsaw. Position the oval template according to the position of the Riolito model‘s predetermined positionfits drain location, relative to the squared wall framing...
... to allow wedi drain trap to be inserted and connected to floor pipe using appropriate ABS compatible or multipurpose cement glue. Please also check cement glue compatibility to floor pipe material. The drain and trap have to be secured to the subfloor. Drain recess cut out must not add deflection to subfloor.
Cut the Adapter 32 mm below the subfloor surface. Make sure that the cut out fits to the Fundo board drain.
Assemble the drain unit following the instruction drawing. wedi‘s Riolito neo bases can be cut to size on all sides making drain positions close to the wall possible. Please do not cut into the linear drains plastic flange integrated into the coated foam part of the base. If you are using a 12.5 mm wedi Building Board, the channel at the new base perimeter must be reestablished to 12.5 x 12.5 mm. When cutting close to the drain channel always leave enough wedi foam for re-making the needed 10 × 10 mm channel.
Glue and seal the wedi drain trap to the DN 50 pipe. Mount the sealing collar to the wedi Riolito neo underside counterpart using a manual phillips screwdriver.
Apply a skim coat and finally a combed through bed of a thinset using modified thinset and a 10 × 10 mm notch trowel.
Press the Fundo firmly into the thinset bed, ensuring that the installation is level and void free. Do not bend or apply uneven pressure when pressing the part into thinset bed and drain trap. This may break the unit‘s seals. Ensure wedi drain‘s sealing gasket is firmly inserted in the wedi trap with no chance that thinset could have pushed into this connection area. This is a tight fit so you should use some water or safe plumbers grease to help. When using plumbers grease, the gasket may retract upward so you need some temporary weight here to keep it fully inserted (thinset bag or tile box). Apply some weight equally and leave on surface and drain area to allow the thinset to initially cure without being disturbed (e.g. thinset bags). Do not step on the drain module to push/connect to drain body or thinset. Ensure there is 100% thinset supporting the drain channel area over a completely flat subfloor.
Set up a continuous 10 mm bead of wedi 610 Adhesive Sealant at the perimeter channel and only in areas where you can immediately install a wedi Building Board into the fresh sealant.
Push the wedi board all the way into the channel of the shower base channel and its bead of sealant. Smooth out any pushed out sealant on inside seam using a putty knife. Fasten the boards directly to the studs starting 300 mm above the base and at a rate of 1 fastener per 300 mm. One extra fastener is set into the seam to the next board to crate a flush transition.
Apply continuous 10 mm beads of sealant between all connections of boards and install with tightly butted seams. Excess sealant must be spread flat with a putty knife. All seams and fastener heads in the assembly are covered with a secondary 10 mm bead of sealant and spread flat. The seams should be covered to 25 mm on either side of seam. All fastener/washers are covered with sealant stretching 25 mm over the washer edges.
wedi Niches are installed in a cut out in the wedi wall and attached with it‘s flange right into the center of 16 o.c. studs. wedi sealant is set along the connection of wall to niche.
2 Fasteners each side of the niche are set to create a flush transition to the wall boards. Another 10 mm bead of wedi sealant is spread over fasteners and seams.
A continuous 10 mm bead of sealant is set into the channel and along the vertical hob notch part. A circle of 10 mm sealant bead is set against the wall boards where the hob attaches. A 10 × 10 mm bed of thinset mortar is applied to the subfloor and just a skimcoat on the foam bottom part of the hob as a best practice. The tightly cut to fit hob is pressed into the connection. Weight is applied on and against the hob (from outside) and another 10 mm bead of sealant is applied over all hob seams and spread flat. The seams must be covered 20 – 25 mm either side of a seam.
