The points shouldn't be too tight as to cause friction between the frame and sash but they shouldn't be loose.

Before putting the putty on, make sure to knead it until it is smooth and free of lumps. Roll it into pencil-sized strips. Apply the first strip in the corner of the frame, working from one corner to the next to ensure it is even and smooth.

Glazier's Points

Write down the exact dimensions of the frame. These dimensions can be taken to a home center or hardware store, and the new frame will be cut a bit smaller. This will ensure that the pane fits snugly and allows for expansion and contraction.

Place the new pane into the frame and push it in place by using your hands. Then, use the tip of your chisel or the back of the putty knife to tap in the glazier's points as illustrated in Figure 11. After you're done, the points should be in line with the top edge of the pane and the raised shoulders of the points should be below the rabbet's lip. groove.

Apply a thin layer glazing compound on the rabbet grooves and edges of the new glass. This will protect and seal the edges. Allow it to dry completely and cure.

After the glazing compound dries and the glazing compound is dry, you can install the new window sash. First, you need to coat the wood with an even layer of linseed.

After removing the old pane, clean the frame and wood. Scrape off any old paint, and sand the rabbet grooves where the glazing points were. These should be sanded to the point of being bare, to allow you to paint them the same color as the rest the frame. After sanding the wood then apply a layer of flax oil. This will help to prolong the life of the frame.

Then, take measurements of the dimensions of the window opening. You will need to measure the horizontal and vertical dimensions of the entire opening, as well as the thickness.
