Things You'll Need:
- Glazing
- putty knife
- ladder
- blow torch or heat gun
- scraper
- latex gloves
- primer paint
- 2 paint brushes

Step 1
Gather needed items. Get together the things listed in "Things You'll Need." Glazing can be bought at any hardware store. Before you buy a specific brand, be sure to look at the directions so you're prepared for what you're getting into. Some glazing has to dry up to 14 days and most should be primer painted when they're dry.

Step 2
Gather the windows which need glazing. It is easiest if the windows are all in one spot and not still in they're frames on the house. This is so you don't have to keep going up and down a ladder and performing a balancing act while trying to work. The best situation is if you are painting the windows after they're glazed. This is because during the process of glazing, the paint on the window is often affected.
-
Step 3
Befor you can apply new glazing, you need to remove the old stuff. Two ways to do this are scraping or heating. If the glazing is very loose, it may just pop off with a little help from a scraper. If it's more stubborn, a blow torch on low setting will work well. Be very careful with the blow torch. The heat can break the window and it can also bubble the paint on the frame. One trick is to use wood to cover the window and protect it from the heat.

Step 4
Now that the putty is removed, remove the points. These are small metal pieces lodged in the wood to hold the glass in place. If they are in good condition, save them for the new glazing because newer points you buy are sometimes too large for older windows.
-
Step 5
Now you should lift the glass out of the frame. If the old glazing is still holding it in, hold the heat gun 1-3 inches above it for 15-30 seconds. This will heat up the glass just enough to warm up the glazing and free the window.
-
Step 6
Now that the glass is removed, scrape and sand the frame to get to the bare wood. The wood should be primed. This is to seal the wood and prevent it from soaking up the oil from the glazing. If this happens, the glazing dries out and cracks off again in about 2 years. Primer takes about 24 hours to dry.
-
Step 7
When the primer is dry you can apply new glazing either by hand or with a caulking tube. Warm up the glazing with a heat gun or by rolling it around in your hand. Apply a thin bead all around the frame and then press the glass into it. Once the glass is tight against the glaze, insert the points. Trim the putty that has squeezed out the opposite side of the frame.
-
Step 8
With your fingers or a putty knife, press the glaze into the glass so the groove is overfilled. To create a finished look, start in any corner and glide theh knife over the putty, pressing it firmly into the frame and cutting off the excess at the same time. Move the knife slowly and at a deep angle. To smooth, use your fingers or a quick back and forth motion with a clean paint brush.

Step 9
Once the glazing is set, it may need to dry for several days. Read the directions for the specific putty you're using. When it is dry, you should probably prime it and paint it. When painting, make sure there is a very small margin of paint from the glazing onto the glass. This so that a seal is created and the glazing is protected.
