Product Description

Wedi Board or 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 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 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 the even surface. 

Our wedi Board prices are competitive and we offer the largest selection of wedi Board Products on the west coast.

Please Note: Wedi building boards are shipped via LTL Freight. We will provide you a shipping quote before processing your order. Larger orders may be eligible for a shipping discount.

Q: 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.
Customer Support answered on January 15, 2018
Q: 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.

Q: 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.
Customer Support answered on July 20, 2018
Q: 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.

Q: 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.

Q: 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.

Q: Can I install 1/2 .in or 1/4 .in board over top of 1/2 .in drywall to cover a fireplace wall with tile. If so do i apply thinset to drywall first.
Hello, You have to use a primer before you use the thinset to apply to drywall. In our case our M-Bond will do. Please note that Wedi board is not recommended to areas subject to 175 Fahrenheit .

Q: Can Wedi shower base be set on 23/32 OSB (thinset)?
Plywood subfloor joist spacing must not exceed 16” o.c. with minimum thickness of T&G exterior grade plywood of 19/32 inch. Joist spacing in excess of 16” o.c. and up to 24: o.c. requires a double layer of 3⁄4” Exterior Grade Plywood T&G subfloor sheets, glued and screwed. This is an acceptable substrate no recommendations for going over OSB. Please give us a call for further recommendations.
Customer Support answered on February 18, 2020
Q: Is there a weight limit for using Wedi board for the floor of a shower. The shower is on a cement slab?
Wedi does not specify a weight limit over concrete. We would recommend getting in touch with Wedi to confirm.

Excellent weatherproof substrate for artwork
Wedi panels are an excellent all-weather, lightweight, easily-cut, rigid substrate for interior/exterior artworks in stone, tile and glass. MWI carries a great selection of thicknesses at good prices, and their order/pickup structure makes it a cinch and a pleasure to obtain. So glad to have an excellent resource like MW in my town!
