It is recommended to work on a stable ladder instead of the ground and to have someone standing below the sash in order to help hold it steady.

Once you have removed all the old putty, prepare the window frame to fit the new pane. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of the width and height. Take these measurements to a hardware store or home center and find a piece glass cut to size. You can also cut the glass yourself if you have the tools you need.

After installing the new pane After installing the new pane, apply a small amount of caulking around the edges to make it weatherproof. Then, you can install a glazier's pointing on the frame's opposite side to secure the pane in place. The points should not be tight enough to create friction between the frame and sash however they should not be loose.

Before putting the putty on, work it in a gentle manner until it's soft and free of lumps. Then you can roll it into pencil-sized strips. The first strip should be glued to the frame's corner. Work from one corner to the next and ensure that it is even and smooth.

Take the dimensions of the frame and note down precise measurements. Bring these measurements to an hardware store or home center and request that the new pane cut smaller than the frame's opening. This will ensure that the pane fits comfortably and allows for expansion and contraction.

Place the new pane into the frame and ecuadortenisclub.com push firmly using your hands. Use the point of the chisel, or the edge of the putty blade to tap the glaziers' points as illustrated in Figure 11.

Apply a small amount of glazing compound on the edges of the new glass and into the rabbet grooves to seal and protect them. Let it dry completely and cure.

Install the new window sash after the glazing compound has dried. The first step is to coat the wood with a thick layer of linseed. This will keep the new putty from sucking in the moisture and drying out and cracking with time. Apply this coat using a brush or the tip of your putty knife, and then use the chisel or the back end from the putty knife to gently hammer in the new sash and glazier's tips into the rabbet grooves. Repeat this procedure every 10 inches around the perimeter of the frame.

Putty

Once the sash is re-installed, apply a new caulk made of silicone around the glass to ensure that it will not leak or change color in time.

Remove the glazing points from the rabbets and the grooves in the sash, where the glass is. If they're difficult to work out, try holding the hand tool, such as a heat gun over them to soften them up first. When using a heating tool, be sure to not scratch the sash's railings and sash.

Make the bed for your new pane after removing the old glaze and putty. Roll a piece of glazing compound between your hands, and form it into a 1/2-inch thick. Then, push it into the rabbets where the glass will be. The glass must rest against the putty on both sides. If needed you want to tap your glass lightly into the rabbet using your thumb.

If the new pane is damaged, you can use a silicone caulk or glass glue that is based on solvents to cover the crack before pressing it into the sash. In other cases, you'll need to apply putty over the crack to create an airtight seal and keep water out.

They are placed under a bead or glazing glue which hardens into solid wedge which holds the wood frame firmly in position and hides the sharp edges.

Once you have the old pane taken away Clean up the frame and wood. Scrape away any paint and sand down the rabbet grooves where the glazing points used to be. These should be sanded to bare wood so that you can paint them the same color as the rest the frame. After sanding the wood, apply a layer of flax oil. This will help extend its life.

Next, measure the width of the window replacement companies opening. It is necessary to measure the horizontal and vertical dimensions of the entire opening, as well as the thickness. Subtract 1/8 inch from each measurement to ensure you get a precise size for the new pane. This will also allow for expansion and contraction of the glass in times of seasonal changes.
