Dap Inc 12121 White Glazing Compound 1 Pint Wood Metal

Product Description

The DAP INC 12121 is a white, knife-grade glazing compound designed to seal and bed glass in wood and metal window sashes. It arrives smooth and ready-mixed, requiring no additional preparation before application. The compound delivers excellent weather resistance, outlasting ordinary window putty in exterior exposure conditions. Installers apply it with a standard putty knife, working it into the sash rabbet to form a tight, weather-resistant seal around the glass pane. It is well suited for both new glazing work and reglazing deteriorated windows on residential and light commercial projects.

This compound is used in residential and commercial window service work wherever wood or metal sash frames require glass bedding and face glazing. Glaziers, general contractors, and maintenance technicians reach for it when replacing broken panes or refurbishing aged window units. The knife-grade consistency allows clean, controlled application without slumping, making it practical for overhead and vertical sash work alike.

Installation Notes

Application is typically performed by a glazier or general maintenance technician using a standard putty knife. Remove all loose or failed glazing compound and clean the sash rabbet thoroughly before applying fresh compound. Work the compound firmly into the rabbet at a consistent angle to achieve a tight seal, then smooth with a wetted knife. Allow adequate cure time before painting over the compound per manufacturer guidance.
