More Details

The wedi Corner Putty Knife is a must-have tool for any professional or DIY installer working with wedi waterproofing systems. Specially engineered for forming clean, seamless 90-degree inside corners between wedi building panels, this lightweight plastic tool helps ensure every joint is watertight, smooth, and ready for tile.

Designed to work in tandem with wedi Joint Sealant, the putty knife glides effortlessly over foam panels to create crisp seams in wet room areas like showers, steam rooms, and tub surrounds. Its compact form fits easily into corners without damaging the surrounding panel structure, while the ergonomic shape makes sealant application fast, consistent, and mess-free.

Unlike makeshift tools or metal putty knives that can gouge the panel surface, the wedi Corner Putty Knife is purpose-built for wedi installations and offers superior control with less cleanup. Use it when building curbless showers, niches, benches, or sealing wall-to-floor transitions—this tool streamlines waterproofing for a more professional finish.

Ideal for use in residential, commercial, and ADA-compliant wet room construction, the wedi Corner Putty Knife is reusable, easy to clean, and essential for forming a long-lasting waterproof seal in every wedi install.

Returned a schluter drain kit to buy the flofx drain and this grate. Cost less and looks way better. Why in the heck would you do it any other way?

Love that this is tile ready and has a warm light tempreture

Search high and low for a niche that could be tiled and had a warm light that could be replaced if it failed. This is the only one I could find.

This is the best shower flange for tiled shower floors

This is the best shower flange for tiled shower floors. I’ve recently started using this flange for our floated mudpack and membrane shower systems. Paired with the FloFx membrane this is a great solution for less cost that some other well known brands on the market. The flexibility in the final drain grate adjustment is a huge bonus.

Looks cool, works well!

I have used several sheet materials for waterproofing, and I can’t tell if this is functionally any different, but it is a solid performing product. I also like the idea of using it in conjunction with the FloFx drain flange so that products designed to work together are being used together.
