If you want to use putty for window repair, then you will have to knead it into the correct consistency. When you are working with putty, it can be difficult to manipulate it until it is the right texture and firmness, but this is a vital part of ensuring that it does the job. When you are fitting putty into a window, it has to be slightly sticky, but not so sticky that it looks more like a caulk. In order to knead it correctly, you will first need to work out the correct texture for your needs, have the right kind of kneading board in order to avoid collecting dirt, and then will have to use elbow grease to get the job done.

Step 1 - Finding Out the Right Consistency

When you are working on your window repair, you need a putty that will stick to the window without being difficult to clean off of it. You need a very sticky putty, around the same consistency as a heavy and dry type of dough bread. You should look at the makers recommendations on the side to find out exactly what you need for your own home improvement,  but trying to keep it a sticky-but-not-too-sticky texture will help you to knead your putty correctly.

Step 2 - Starting to Knead

Get yourself a suitable kneading board. You will need one which is perfectly flat and smooth, rather like a marble worktop, or perhaps a piece of the old glass that you have just removed from your window. This will help prevent you from picking up pieces in the putty as you knead it, and will also give you a hard surface on which to  press out the putty. You can now cut your putty into small pieces, ready for rolling. If you have a tub of putty, take out enough to fit into one hand, and place it on the kneading board. You should first roll it out with your hand.

Step 3 -  Softening the Putty

As you roll the putty around in your hands, you should find that it becomes softer and easier to work with. Putty can be softened over time by repeatedly rolling out the material, and even manipulating it into flat and then round shapes. Don't allow the putty to become too soft, otherwise it might become too soft to stick into the window frame.

Step 4 - Working the Putty

Now that the putty is soft enough to manipulate, you should turn it around on the kneading board until it becomes pliable. You should also be removing any lumps and unwanted bits from the putty by kneading it as you go. Once it is free of these lumps, you can then go on to work the putty into small strips, ending up about the size and length of a pencil. When this is done, you should be able to push the putty into the edges of the window frame.
