Wedi Board or Wedi Building Panels are much more than a simple tile backer board and offer almost endless installation opportunities. Wedi Board Panels are available in a wide variety of thicknesses and sizes and they are compatible with most any substructure. They are lightweight, internally waterproof, and dimensionally stable, making them fast, clean and simple to work with. The blue waterproof core is CFC- and HBCD free, made from waterproof extruded polystyrene foam, reinforced with fiberglass mesh on both sides. They are coated with synthetic polymer resin mortar, which fully embeds the mesh layer resulting in the panel‘s strength and the ability to develop the highest adhesion strength to virtually any type of thinbed mortar. The embedded mesh eliminates the risk of delamination of installation layers.

Wedi Boards (Panels) combine the benefits of the latest manufacturing technology and material quality with sound and traditional benefits our trades enjoy. They are waterproof, lightweight, easy to clean, to cut, and still incredibly strong and bond friendly.

Wedi Panels (Boards) can be used with any type of thinset mortar application. The Wedi Building Panel can be tiled with all types of ceramic, glass, or stone tile, whether they are mosaic or large format tiles. Especially large and thin tile can be installed with confidence over Wedi Boards, due to their stiffness, strength, and even surface.

Customer Questions
Can you cut this material into circular patterns? Or only squares/rectangles. I am looking for cutting substrates for mosaic use.
How do you cut them? razor knife, saw etc?
Yes, a razor knife is the easiest way to cut Wedi Board.
Can I add extra Wedi building panels and other supplies to a Fundo Shower kit and still get free shipping to a commercial address?
The free shipping is on the Fundo primo kits and bases only. However, in calculating shipping costs for the entire order, a shipping discount will be applied in consideration of the free shipping on the Fundo Primo Products.
Can Wedi board be set in thinset?
Yes, Wedi board can be set into thinset, however without knowing more about your project, we can't say whether we would recommend that for your application.
What would be a application for the 1/8” ? I contemplated using on drywall or also on floor to adjust door way transition height
The 1/8 .in is used mostly for adjusting transitions, like if you have 3/8 inch thick tile and you have a mosaic that is thinner going in as accent, you would use 1/8 to flush it up. Please let us know if you have any questions about your project, we are happy to help.
I have an airstream that I need to re line the inside walls so I can paint them. Can I use wedi for this? Will it bend into the dome shape?
Wedi board would not work in this application, made to be a backer board for tile surfaces. I would get on a vintage airstream blog and find out what materials they recommend for relining the walls.
Can I do painting on this product and then resin over it?
Yes, you can paint this product and then resin over it? However, wedi boards are not intended to be used in this manner and will not be covered under warranty as such.
could I use the 1/4 .in on the wall of my new construction over 1/2 .in osb sheathing as a vapor barrier and scratch coat for a 1/2 .in thick stone veneer?
Wedi board is not classified as a vapor barrier, I have sent you a letter from wedi, as they may work for your project but need some additional considerations.
Can I use 1/2” wedi over 16OC studs for a thin cultured stone accent wall in a house? Would be dustless and much easier than carrying cement board.
Yes that application would work, make sure to use wedi washers and screws to mount the wedi board to the studs.
Can 1/4 in Wedi board be applied over cement before tiling in order to insulate the floor? If so, what type of adhesive should be used?
Yes, you would use thinset mortar to set the wedi board.
What thickness size can I use for shower walls
You can use many different sizes for shower walls but the most common is the 1/2" thickness.
I’d like to build a 4’x2’ mosaic backsplash on 1/8” thick Wedi. Ideally, I’ll glue down the mosaic pieces and grout before attaching it to existing drywall, then touch-up grout on edges as needed. Can I glue it to the existing drywall with construction adhesive? Does this plan sound like it’ll work? Thank you
We would recommend a high grade thinset like instead of using a construction grade adhesive.
Can I install 1/4 inch Wedi board over existing plaster and lath three sided tub enclosure in order to avoid tearing out the plaster and lath down to the studs?
yes, use thinset with 1/4" notched trowel in addition to screws and washers. You will need to use the longer screws as well.
I also have an Airstream trailer I’m renovating, and am looking for a flexible waterproof panel to tile on in the shower, to be added over the top of the existing curved aluminum outside wall of the trailer. Will the 1/8 inch thick panel bend and still safely adhere to the curved wall with thin set, and be tiled on?
Tiling in an Airstream is a bit tricky because of vibration and flexibility. I would check out what a few people have done online, like this guy:
Is there another way to seal the edges of the Wedi board (1/4 or 1/2 inch) besides Fibatape? It doesn't stick to the thin edges well when trying to 'glue' it down with Thinset (for large mosaic projects). Also, what is the best type of paint to paint it with ? Thank You
Wedi joint sealant is all that is required to seal joints between wedi board, and of course wedi fasteners (screws and washers) to mount and hold the joints together. For an extra layer of protection, wedi fleece tape works well over joints. Also regular latex paints work for painting the wedi board.
