Glazier's paste, also known as PUTTY, is a type of adhesive used to seal and fill gaps in windows and other glass surfaces. It is made from a combination of linseed oil, whiting, and other ingredients. PUTTY is a soft, pliable material that can be easily molded and shaped to fit the desired area. It is often used to repair broken glass or to fill in gaps between window frames and glass panes. PUTTY is also used to create a waterproof seal around window frames and to prevent air and moisture from entering the home.
