Building Panels

Does the writing on the wedi Building Panel need to face out during an installation?

No, it is not required but recommended for easier identification in cases of building inspections.

If I have 24 in. studs on the walls, how can I use ½ in. wedi building panel? And is there a way to use thicker board?

wedi 2 in. thick building panels can span framing spaced at up to 24 in. Thinner wedi panels should only be installed on such framing, if cross framing is installed (spaced every 16 in. centered).

Can I just glue my building panel to the studs and not use fasteners?

This is not recommended over vertical framed substrates, or on ceiling framework. wedi joint sealant has been tested to successfully (and over time) adhere wedi building panel to wooden and metal framing on walls and ceilings, and it can carry the load required. However, the wedi joint sealant depends on pressure being applied equally in all areas where it is used, and for up to 30 minutes- in ideal climate conditions. This is hard to achieve on a project site, so we do not recommend it.

Can I use building panel to extend a shower base?

No, this is not recommended. wedi only warrants the use of wedi pre-sloped bases or extension panels for use in a shower base.

If I have a flat area before the shower can I use building panel and tie it into the base?

Yes, this should be done by notching the building panel edge where it connects with the base’s channel. The connection shall be adhered and sealed with wedi joint sealant.

Can I use 1/8 in. wedi panel in the back of a niche to make it 3/8 in. deeper?

Yes, where a framed out niche is installed on site, this can be done safely. The 1/8 in. back panel should be installed first, and cover the entire backing for the niche.

Can I make a curb out of wedi 2 in. building panel?

It is not recommended, unless a proper slope is safely constructed into such curb, as well as the tree tileable sides of such curb are covered with a cement bonding surface (e.g. by using several building panels and their coated surfaces). All curb construction should be safely designed to carry its designated load. When in doubt, please contact wedi.

Can I build a floating/suspended seat or bench out of 2 in. wedi Building Panel?

Yes, build a custom floating corner seat up to 18“ in length in each of the two sides of the walls you want to attach it to . This can be made using a minimum 2“ thick wedi panel. Two of these panels can be glued to 4“ or thicker if needed using thinset mortar. The thicker a wedi panel made seat construction, the higher its load capability due to increased bending strength and adhesion surface. These field made custom seats can easily carry up to 250 lbs if installed properly. Use wedi joint sealant to bond the seat to the wall, but make sure the joint sealant is spread over the entire contact surface between wedi seat panel and wedi wall. You should use a fine tooth adhesive trowel with minimum 1/8” x 1/4” notches. All seams from seat to wall (on top of seat and below) shall be sealed over widely (1” either side of seam) using wedi joint sealant and a putty knife. Once this sealant has set, use wedi alkali resistant, and self- adhesive, mesh tape over the seams of top of seat to wall prior to tiling.

Floating standard corner seats are also available as a prefabricated product assembly system including wall mounting brackets. These seats are also 4 inches thick and can carry up to 350 lbs of weight safely.

Floating custom straight benches can also be installed by using 2 two 2 in. wedi panels which are thinset adhered to each other. These seats must then be adhered to a wedi wall on three sides in a shower stall. These seats may be up to 18 inches deep and 72 inches wide or long. Use wedi joint sealant to bond the bench to the wall, but make sure the joint sealant is spread over the entire contact surface between wedi panel and wedi wall. You should use a fine tooth adhesive trowel with minimum 1/8” x 1/4” notches. All seams from bench to wall (on top of seat and below) shall be sealed over widely (1” either side of seam) using wedi joint sealant and a putty knife. Once this sealant has set, use wedi alkali resistant, and self- adhesive, mesh tape over the seams of top of bench to wall prior to tiling.

A Floating standard straight bench is also available as a prefabricated product assembly system including wall mounting brackets. This bench is also 4 inches thick and is 48 inches long but can be cut shorter if needed. It can carry up to 500 lbs of weight safely.

When building a seat from the floor up, it‘s best to apply standard framing practices. Install vertical support panels (2”) against walls, as sides to the seat, and for the front. wedi 2“ wedi building panel is also installed, within the seat construction, every 18“ for support. Include a sloped top (slope may be fabricated using wedi joint sealant wet shims or by cutting all supports accordingly) . After sealing and reinforcing the seams in the assembly, as well as seams between seat and wall with wedi joint sealant, you may have additional blue foam exposed. Simply key in thinset over these areas or install a wedi panel strip over these using wedi joint sealant. Cutting areas back to have them covered with a strip that is flush with the seat surface should considered when cutting and dry-fitting the seat assembly. A wedi building strip to cover exposed blue foam is definitely needed when the tile in this area will not overlap from the blue foam area onto the cement coated seat area (such as when working with mosaics). When building floor standing seats or benches in wert areas and over sloped surfaces, the front vertical seat panel will show a gap to the floor surface. This gap shall not be filled with sealant but should be backfilled with thinset mortar for strong support. wedi mesh tape is used in this thinset mortar application for reinforcement. When installing such seats or benches against areas which may be tiled already, or walls made of cement board or EPS panels, or which may, for any other reason(s) potentially allow water to enter the seat (e.g. from below wall tiles) it must be ensured it will not get stuck in the seat. The mesh and thinset cover over the front panel gap will allow water to exit. But if the floor was already tiled, and the use of thinset and mesh is not possible, it will be a good measure to drill a few relief holes into the bottom areas of the seat before tiling.
