How to paint a Window

How to paint windows.

There are several types of window;

Casement. This is basically the type of window in which sashes(parts that hold the glass) open on hinges like doors. They are usually made up of opening sashes and fixed(non-opening) sashes. There are many variations but generally if a sash moves away from the window frame in some degree then it can be classed as casement.
Sliding Sash. The most common is the vertical sliding sash, horizontal sliding sash being usually made of metal. the sashes should overlap but are often difficult to move because of broken sash-cords(thin rope fixed to the sides of the sashes and use weights and pulleys to control the movement of the sash) or jammed up with overpainting.

Brushes required. 1"(25mm), 2"(50mm). In general use the size of brush you feel most comfortable with. I have seen some professional painters do nearly everthing with a 4" brush but it needs a great deal of skill and experience. Generally you should use as small a brush as you think necessary. For windows and intricate cutting in work it is best to use worn down brushes if you have them. New brushes can be shaped by carefully burning the bristles and then sandpapering them.
