          Q:What is the minimum subfloor thickness to install these over?
          by|Oct 24, 2019
          1 Answer
          Answer This Question

          A:  Southcreek - General Limitations / Requirements (Concrete & Wood Subfloors) wedi Product Systems are only used for interior installations. Do not use as a wear surface or without tile / stone or other suitable coverings. Do not use organic mastic adhesives for setting tile on wedi Systems in wet areas. Use only thinset mortar setting materials suitable for installation and adhesion to the specific substrate / subfloor type. Adhesive coverage under tile or other suitable surface finishes in wet area installations must be a minimum of 95%. Certain substrates must be primed prior to thinset mortar attachment. Ensure tile and setting materials incl. grout are suitable for the application (e.g. submerged applications or steam rooms) Do not use where substrate is subject to excessive moisture and moisture content changes. Do not use over substrates including, but not limited to: general particle board (specific exceptions apply), luan, asbestos, plank, bamboo, hardwood, chipboard, sponge backed vinyl tile/flooring, laminates, fiberglass based surfaces, metal or steel surfaces. Do not install over any dimensionally unstable surfaces. Consult wedi for questions regarding specific approved installations not listed here. Subfloors must be clean, even, sufficiently load-bearing and dry (cured). Residues, oil, waxes, grease or other contaminants acting as possible bond breakers must be removed. Deflection of all subfloor installations must not exceed L/360 for ceramic tile installations and L/720 for dimensional stone installations over wedi product under consideration of live and dead loads measured between joists. Any leveling of the subfloor must be done prior to installing wedi product and tile. Subfloor maximum variation from plane must not exceed ¼” (6.4 mm) in 10 ft. (3050 mm) and 1/16” (1.6 mm) in 12” (304.8 mm) when tile over wedi product is used and all edges of the tile shorter than 15” (381 mm). For installations over wedi product using tile with at least one edge 15” (381 mm) or longer in length, maximum allowable variation is 1/8” (3.2 mm) in 10 ft. (3050 mm) and no more than 1/16” (1.6 mm) in 12” (304.8 mm). Make sure to use leveling materials adequate to the challenges of the application. When leveling or building up larger areas including outside the shower please do not use material that can be affected by even low water exposure. wedi products should not be installed over bowl shaped, uneven structures unless suitability is specifically determined for a wedi product. A wedi installation does not replace the need for Expansion and/ or Movement joint placement within a tile installation. Please follow recommendations found in the TCNA guidelines (Detail EJ171). All installations shall be in conformance with IRC for residential installations and IBC for commercial installations or applicable building codes in a region including the consideration of properly designed substrates and subfloors. All installations including the consideration of properly designed substrates and subfloors should be in compliance with current TCNA Handbook for Ceramic, Glass and Stone Tile Installation,

            I am writing a review under this as well as other Wedi kits .This is to cover anyone that is looking Wedi systems We purchased a Wedi complete shower kit With even the most limited knowledge and a little help from a Wedi rep ,anyone can install this and do a perfect or near perfect job. You need to make sure that you carefully read the instructions, watch some of the youtube videos on this system and then take your time doing the install We found buying the complete kit the cheapest way to go and the best If you look at making a bed or buying a different type of shower floor/base, and all the stuff needed add in something you forgot and have to go get ,and the complete kit is a life saver After watching hours of youtube we saw how much easier this system is to install over others

              Just what I needed for my shower!
              Excellent kit, but I think it should come with more caulking.

              Wedi for mosaics?
              I had thought the Wedi board was thicker - it is very thin. Should have read the description better. I use the Wedi for mosaic projects. 1/8 is really thin. However, if I glue two of the boards together, I have a perfect substract that is strong.

                Cost was much higher than normal backer board but the lightweight material and easy functionality was well worth it. Easy to use for a one person job.

                Great stuff
                This material is easy to work with albeit expensive. Lightweight, waterproof and has a radiant value to it that acra as a thermal break for undertile heating. I installed it and we love our heated floors. Shower is next!

                Thank you Tyler for your comments.
                wedi Building Panels are ideal for use beneath floor heating systems whether you have a warm-water heating or an electrical floor warming or heating system. The panel’s insulation properties isolate the heat from the substrate and guide it straight into the room thus saving energy and reducing warm up time, as well as supporting equal distribution of warmth.
