Chem-Calk 916 Aluminum Stone Textured Sealant, 10.1 oz

Description

916 in aluminum stone is a textured polyurethane calk for exterior joint sealing where the finished bead needs to visually blend with concrete, masonry, stone, and other rough building materials. It is a one-component, moisture-curing sealant that tools like a paste and cures into a flexible rubber seal.

Where This Calk Gets Used

Use 916 on perimeter joints around masonry, windows, doors, construction joints, and control or expansion joints where a smooth sealant would stand out against textured surfaces. The aluminum stone color gives installers a neutral gray tone for concrete and architectural stone details, while the textured finish helps the bead sit more naturally beside rough or troweled materials.

Bostik information describes 916 as designed for dynamic joint movement totaling 50 percent of original joint geometry, expressed as plus or minus 25 percent. That movement capability is the reason this product belongs in properly designed joints rather than as a rigid patch. It needs clean joint faces, proper depth control, and tooling that presses the sealant against both sides of the joint.

How This Calk Holds Up

Once exposed to atmospheric moisture, 916 cures to a tough, flexible rubber. Published data lists stable performance across weather exposure and a temperature range from -40 degrees F to 150 degrees F. The non-sag consistency helps keep the bead in place on vertical masonry and facade work, while the textured appearance makes it useful when the repair should not read as a shiny smooth stripe against concrete.
