Dap Inc 12019 Glazing Compound 1 Gallon White Knife Grade

Product Description

The DAP INC 12019 is a knife-grade glazing compound formulated for sealing and bedding glass in wood and metal sashes. It arrives smooth and ready-mixed, requiring no additional prep before application. The compound delivers excellent weather resistance once cured, outlasting standard window putty in outdoor exposure conditions. This is a trade-grade product used by glaziers, window installers, and general contractors on both new construction and replacement window work. Each unit is packaged in a 1-gallon container, white in color, and sold in a package quantity of 2.

This glazing compound is suited for residential and light commercial applications where glass lights are set into wood or metal sash frames. It is commonly applied during window restoration, single-pane glass replacement, and storefront glazing work where a durable, weather-resistant seal is required between the glass and the frame. The knife-grade consistency allows for clean tooling and finishing with standard glazing knives without thinning or modification.

Installation Notes

Installation is typically performed by a glazier or experienced general contractor. Clean and dry the sash rabbet thoroughly before applying compound to ensure proper adhesion. Apply with a glazing knife, pressing the compound firmly against the glass and sash, then tool to a clean bevel. Allow adequate cure time before painting over the compound surface.
