Window glazing compound, or ‘putty’, is a clay-like substance used to seal glass panes into wood framed windows. When installed, this clay-like substance oxidizes and becomes hard. The linseed oil usually contained in the compound speeds up the process of hardening the compound. However, with time, the compound may become extremely brittle. The cracks on the surface may no longer secure and seal the window panes. In this situation, old compound must be replaced with new glazing compound. The process itself is not difficult but is better to be trusted to professionals.
First, you need to use a putty knife to remove the old compound. If the glazing compound is still secured and cannot be removed with a knife, you can use the heat gun, which will soften the compound before its removal. Second, make sure you don’t remove the original glazing points along with the old glazing compound. If it happens, you will need to have new glazing points installed in your window. Use the edge of your putty knife to scrape away all traces of the old glazing compound from the glass and wood areas of the window. You need to have the area absolutely clean, to make sure that the new glazing compound properly seals the window in place. Use rubber gloves while working with the glazing compound. Work the compound with your hands until it becomes soft and malleable. Lay the sections and stripes of the glazing compound along the window panes, where the old glazing compound was
The last point is pressing the new glazing compound against the glass and the frame. You should have the putty knife directed at a 45 degree angle from the glass. This is the best way toguarantee that the compound is pressed firmly into place against the glass and the window frame. As you can see, the whole process looks easy and does not cause any serious trouble. However, as always, you should better trust your glazing compound tasks to a professional, to guarantee that the whole process goes smoothly and does not cause you any problems.
