Building Stronger, Smarter Corners: Wesco Partners with 3WAY® for Modular Excellence

Audree Grubesic. Dec 31, 2025. 3 min read.

Summary

Wesco partnered with 3WAY® to address drywall corner cracking in modular construction. The product is an inside drywall corner joint designed for straight lines, added strength, and long-term crack resistance.

Why Corners Fail in Modular Construction

Modular units move during transport and installation. That movement can stress taped and mudded joints. Even small shifts can cause visible cracking in three-way inside corners.

This creates aesthetic issues, added labor, material costs, and repair time.

3WAY® Advantage

The 3WAY Inside Drywall Corner Joint is an engineered solution. It is designed to outperform traditional finishing methods.

Reinforced backing covers gaps, blown-out board, and framing irregularities.
High tensile strength resists tearing, stretching, and distortion.
Wafer-thin beveled edges help with joint treatment and smooth finishing.
Roughened surface improves bonding with joint compound.
Accurately cut creases help produce folds and straight lines.
Greater durability provides long-term crack resistance.

Installation Benefits

Installs in seconds.
Requires no specialized skills.
Can be applied before or after taping.
Uses reinforced card and a roughened surface for a stronger bond with drywall mud.
Reduces rework, callbacks, and finishing time.

How It Is Applied

Apply compound. Adjust the flap for fit. Press the 3WAY® into place with a drywall knife. Feather the edges with additional coats. After drying, it sands smoothly and is ready for finishing.
