Painting a casement window is really just a matter of logic as is painting all opening frames. Doors, garage doors, sash windows, all have an order they are best painted in and our related projects list on the left should cover most of these jobs. As we mention in the other "painting a window" projects don’t be afraid of getting a little paint on the glass. We have a magic tool for removing this extra paint further down.
It will be pretty obvious to most of you that the window shown in this project is actually a double glazed uPVC window, but its OK to use as an example as we haven’t actually painted a wooden casement window with intermediary stiles for a very long time and we don’t have a photo of one.
As with everything in the building Industry, the best job will only be achieved after the best preparation so sand your window down well then brush away, or even hoover, all of the dust. Open the windows and find a way to secure the open casements in position. This is quite easily done by tacking a small piece of timber to the underside of the opening sash and the other end to the underside of the cill.
Remove all of the window furniture. Use a good quality brush (see our types of paint brush project) and make sure that whatever you use to stand on to reach the higher parts of the window is safe and secure. Even a large window will not use a lot of paint so tip some of your paint into a small paint kettle with a handle which will make it so much easier to handle.
- Always paint opening sections of any window first. The frame is the last thing to be painted. We always start with the hinge edge of the windows and up over the top edge, down the front, or leading edge and round underneath the window back to the hinge side. If there are two openers, do the same with both.
- Paint any glazing bars by painting the left side of every vertical bar, then the right side of every vertical bar. Then the underside of every horizontal bar, then the top side. Finally paint the front of all glazing bars.
- Paint the rails and stiles of the opening windows.
- Paint the frame. Paint the hinge sides first, then the intermediary stiles, then the lock/latch side, then top and finally bottom sections. Last to be painted is the underside of the cill. These instructions may go against others you have seen but very few of them do it for a living! The underside of the cill is the least likely to be touched, leant on or rained on so it should be the last to be painted because then, it will be the last to dry.
Finally use the window scraper in the picture to clean off any paint on the glass. See our painting sash windows project for instructions on how to do this effectively and neatly.
