6) Remove all remnants of glazing putty and glass. If the glass is of no historical importance,. break it out, over a large garbage can. This should remove most of the glazing putty as the glass is broken. If the glass is of historical importance, then attempt to save as much original glass as possible for re -installation later. The average glass loss under this scenario is about 20%. 7) Repair individual window sashes, as needed. Clamp and re - pin sagging rails and stiles, & use architectural epoxies to repair any rotted wood on the outside, or on the inside if it will be painted. If there is rotted wood on the inside, and it will be finished naturally, it should have new wood that matches the original spliced in. If a sash is disassembled, DO NOT glue -up the mortise and tenon joints when re -assembling. Pinning the joints with two hot -dipped, galvanized finish nails that have been cut off shorter than the thickness of the sash and driven into the mortise and tenon joint, at opposing angles, if sufficient as long as the joint is clamped snuggly before pinning. Provide new parting and interior stop as needed to closely match originals. 8) Repair jambs as needed with wood or exterior architectural epoxies. If the jamb is to be natural, use exterior grade fillers that will take a stain. 9) Lightly sand (to 120 grit sandpaper), all wood jambs, sills, interior stops, & window sashes. Prime the faces, top, and bottom edges of the window sashes ONLY; do NOT prime or paint the sides of the sash. Prime everything else, including the glazing bed, with alkyd oil based primer. 10) Install window glass into a bed of acrylic -latex, siliconized caulking, and secure it with adequate glazing points All new glass should be double strength. Install new glazing putty so that putty, at glass, is in the same sight plane as the interior molding edge of the sash. One glazing putty to use is #1230 Permaglaze by Schnee -Moorhead.
