It might seem a little intimidating to paint a sliding window frame, mostly because of the fear of painting your window closed, but with the proper steps, it can be easy to paint your sliding sash window.
The best way to start is to gather all of your supplies so that you are completed prepared and will not have to stop your painting efforts to grab something. Painting a window requires the same supplies that you would need if you were painting another surface in your home. The basic supplies that are needed include a drop cloth, paint brushes, primer, paint, masking tape, sand paper and filler.
Prepare Your Surface
As is the case for painting any other surface, it is important to prepare your surface. The best way to prepare the wood around your window is to sand the entire surface down to give it a rough surface for the paint to adhere to. If there are any gaps or holes in the wood, make sure to use your filler to fill them in and then sand those areas down as well. If you wish to use masking tape to tape off the glass to lessen the worry about paint dripping on the glass you can. Many people opt to not using masking tape and worry about any drips later on, that is a personal choice for each painter.
After you have sanded the surface, it is time to begin painting. Before you actually break out the paint, it is important to remember to reverse the sashes so that you can begin painting them first without worrying about painting your windows closed. Start painting with your primer first, to get your windows ready to absorb the actual paint the most efficiently. The order to paint the sashes in is important in order to reduce the risk of ruining any paint that you have already done:
- Start with the inside frame of the rear sash
- Next you can paint the bottom part of the front sash that is exposed as well as the part of the bottom window frame
- Now you can paint the side tracks until you get to the sashes
Once you have completed these steps it is time to reverse the windows to complete your painting. When you reverse the windows, make sure that the already painted windows do not touch any surfaces, only reverse them as much as necessary to paint the rest of the windows. You can now paint the rest of the window that was not already painted.
- Start with the inside frame of the lower sash
- Paint the top half of the front sash
- Paint the top of the window frame where the sash will eventually close
- Finish with the tracks at the top of the window
Once you have painted the entire window sash with primer, it is time to prime the sill. It is best to start with the bottom of the sill and work your way up around the entire frame of the window sash.
Once you have finished priming, it is imperative to wait until the primer is dry, then you can finish with your actual paint, using the same method as above to complete the painting of your sliding sash windows.
