The J Bead is designed to protect the bottom edge of sheathing boards while eliminating the need for costly back wrapping. This durable trim helps create a clean, professional finish for exterior wall systems.
Featuring a wide return flange with bonding grooves and perforations , the J Bead ensures a strong bond between the base coat, casing bead, and the sheathing surface. Its design improves adhesion and enhances overall system performance.
The bead also includes a built-in 1/8″ stop, helping installers maintain the correct base and finish coat thickness for consistent, high-quality results.
Trim-tex recommends following industry-standard installation methods. All butt joints, intersections, and ends should be caulked with elastomeric sealant during installation.
