Chem-Calk 916 Medium Bronze Textured Sealant, 10.1 oz

Description

916 in medium bronze is a textured polyurethane calk for construction joints where the sealant bead needs to blend with darker masonry, bronze frames, concrete details, or architectural panels. The one-component material guns from a standard cartridge, holds a non-sag profile, and cures with atmospheric moisture into a flexible rubber seal.

Where This Calk Gets Used

Use 916 for perimeter sealing around windows and doors, masonry openings, construction joints, and control or expansion joints. The medium bronze color helps on storefronts, darker facade materials, and concrete transitions where white or gray would draw too much attention. Its textured appearance also makes it more suitable than a smooth sealant on rough concrete and masonry because the finished bead looks closer to the surrounding material.

The product is designed for dynamic joint movement totaling 50 percent of original joint geometry, or plus or minus 25 percent. That makes it a construction joint sealant, not a rigid filler. The joint still needs clean, sound sidewalls, proper depth, and tooling that presses the bead firmly into the surfaces it must seal.

How This Calk Holds Up

Bostik lists 916 as a one-component textured polyurethane sealant and adhesive with performance across weather exposure and a cured service temperature range from -40 degrees F to 150 degrees F. The toothpaste-like consistency helps installers tool clean beads on vertical work without slump. Once cured, the flexible rubber profile supports movement from seasonal expansion, vibration, and ordinary building envelope changes.
