A Practical Guide to Using Glass Putty

Glass putty is used to fix and seal glass panes in wooden and metal frames.

Good quality putty should be soft, easy to work with, and should not crack quickly after drying.

Before applying, clean the rebate, remove old putty, and ensure the glass sits firmly. Press the putty evenly and finish with a smooth angle so water can run off.

For longer life, choose a reliable brand and avoid very hard or dry putty that is difficult to shape.
