More Details

The wedi Subliner Dry Seal Tape Corner Pieces are precision-molded inside and outside corner seals designed to provide watertight transitions between wedi building panels and tiled substrates in wet room environments. Each corner piece is made from wedi’s signature Subliner Dry membrane—a highly tear-resistant, flexible, and fleece-laminated polyethylene material—engineered for quick application and maximum adhesion.

These preformed corners eliminate the need for time-consuming folding or cutting, ensuring a perfect fit for 90-degree corners. Whether you're a contractor working on tight deadlines or a DIY homeowner upgrading a shower, these ready-to-install corner pieces streamline the waterproofing process. Use them with wedi Subliner Dry Sheet Membrane, Vapor 85 building boards, or over compatible substrates in tiled installations. Ideal for bathrooms, steam rooms, spas, and anywhere tile meets moisture.

The Inside Corner variant is designed to seal where two walls or a wall and floor meet, while the Outside Corner variant is ideal for outside 90° joints like wall protrusions or curb exteriors. Both versions ensure your waterproofing system maintains integrity at these critical junctions.
