Can you please provide a visual explanation .........i mean some pictures to explain it. There is some ambiguity i couldnot understand it........ 

When you replace your window glass first you decide which color glass you want and which type of design you preferred. Then you take decision for replacing the window glass. 

Before starting to replace broken glass, put on a pair of gloves and a pair of glasses. It is easy for bits of glass to chip and fly.

Carefully remove all pieces of glass being careful to clean up the area around the window to prevent injury and cuts. Use pliers to grip pieces of glass still in the window.




With a chisel or jackknife, remove the old putty. Be careful not to gouge the wooden frame. As you proceed around the frame you will find glaziers points (small steel triangles) in wooden frames or spring clips in metal window frames. Save these points or clips. Be sure all old putty is removed so the glass will slide into place easily.




With sandpaper or a rasp, clean off bits of putty which might remain on the wood or metal sash.


Paint the frame with linseed oil, wood preservative, or an oil base paint. This seals the wood surface under the putty and prevents the metal frame from rusting. A fast drying paint is most convenient.


Measure the size of the glass with a yardstick or folding rule. A steel rule may sag causing errors in dimensions. Allow 1/8" clearance on all sides so reduce each measured dimension by 1/4". Buy the glass cut to the correct size.


Knead the glazing compound and form it into strings no bigger than a pencil. Lay a string of compound along one side at a time and force it onto the glass and wood frame with the tip of a putty knife. Smudges from the compound can be removed later with a cloth dipped in turpentine.

Step 9.

After the glazing compound has dried, paint it to finish sealing the seams between the glass and the compound, and the wood and the compound.
