You have a lot of choice here, there are a few questions to ask yourself to get the right Wedi product for your installation. The steps are:
1. Select your tray
2. Select your drain
3 Select the sealing set
4. Any additional products
In order to select your tray you need to first ask yourself: are you installing on to wooden floorboards, or a solid concrete floor.
Wooden Floors: The following is a suitable suggestion installation on wooden floors / floorboards:Wedi Fundo Ligno Shower Base. At least 44mm is required for the space above the drain body to house the shower element, at this stage you need to cut out enough room for this and the drain element. Measure carefully at this point and allow enough room as per the instructions. After this you install the dedicated supporting substructure (Wedi Fundo Ligno drain substructure element) at this point you connect the drain to your drainage pipework and reinsert the removed flooring around the recessed drain where required (or use the Wedi Fundo Ligno drain substructure element, see below). Next, infill the recess, most fitters use a sand and cement mortar mix, smoothing it level with the top of the drain body, leaving 20mm to accommodate the support plate which is on the underside of the Wedi board round the waste hole (for added strength). Now insert the O-ring (from above) and screw in the sealing collar. Pre-treating any wooden surfaces with a primer add a flexible cement based tile adhesive over the whole surface area of the underneath of the actual Wedi Shower element board. This is now ready to be installed into the recess, making sure it is all level now seal the entire outer perimeter with the: Wedi Fundo Sealing Set. Leave this to set for 12 hours, then tile! Tip. You can cut down on time by using the Wedi Fundo Ligno drain substructure element. This is a pre-formed foam element especially designed to support the drain.
Screed or Concrete Floors: The following is a suitable suggestion for installation on screed or concrete floors. Wedi Fundo Primo Shower Base. Leave a suitable recess in the screed / concrete floor. Join up your drainage pipework, infill the recess with a sand and cement mix smoothing it to a level leaving 43mm between the top of the drain body and what will be the final floor level. Put the O-ring into the groove, now screw the clamping collar into the main sealing collar. Now you’ll need to apply a flexible tile adhesive to the underneath of the shower element board, put this into the recess making sure it is all level. At this point you’ll need to seal the whole of the outside perimeter with Wedi Fundo Sealing Set. Leaving this to set and dry for 12 hours will ensure it’s ready for tiling on to. Tip. To save time on filling with mortar (around the pipework in the first steps) purchase the: Wedi Fundo Primo Easy Set. This helps install to the right height quickly: Glue the Easy Set onto a level subflooring, fix together the individual pieces with Wedi 610 adhesive, position the drain unit into the recess. Once this has dried fix in your connecting pipework. See Wedi’s fitting videos for clarification.
You may have seen various images of bathrooms in magazines or on our website with tiled walls featuring alcoves for storage and decoration, and wondered how these are created. These kinds of shapes can be built with Wedi’s prefabricated elements. Wedi offer a preformed Wedi niche solution that can simply be tiled onto, this is guaranteed 100% waterproof as part of a Wedi system, so you don’t have to worry about your desired design feature compromising the integrity of the waterproofing structure on your shower wall. Individual niches are available in 4 sizes, in addition Wedi have developed an all in one wall section with a preformed niche. Tip. Ask your tiler to trim the opening with a metallic strip for a clean cut modern edge.
