Position the new glass in the opening. Lay glazing points about 6 inches apart against the glass. Use a putty knife to wiggle them into the frame. Knead glazing compound to make it warm and pliable. Then roll it into a snake shape and press it in place. To smooth the compound, start at one corner and, holding your knife at about a 60° angle, try to make a single pass.

Tips from pros
Prime any bare wood before replacing glass. Lay a bead of acrylic caulk in the frame to seal the glass.

Safety
Always wear heavy gloves and eye protection when you handle glass. For more safety instructions please visit National Institute for Occupational Safety and Health.

Money-saving tips
Glass can’t easily be re-cut if you order or cut it slightly too large. Don’t measure for the new pane until you’ve removed the old putty from the sash. Then, cut or order glass 1/8 inch smaller than the rabbet (a rectangular groove in the edge of the sash)
