PREPARE WINDOWS PAINTING
If you’ve decided to change sashcords and plan on painting, now is the time to prepare the windows.
IF YOU HAVE THE WINDOW OUT
Now is the time to sand back the old paint, take out old putty and apply fresh putty and prime.
Using a sanding disk method is primarily for those very familiar with their power tools. Course sandpaper followed by fine in a sander is easier when the window is out.
The important thing is not to catch the glass, or you will end up with irrepairable gouge marks on the glass.
RESTORING WINDOW FUNCTION
Window function includes replacing sash cords, spiral balances and often to allow the top sash to work freely again.
If planning to restore function to the top sash when changing cords or balances, the main problem will have been the paint.
Not only is there paint buildup in the track, but also on the parting bead, and also the ridges of paint on the sashes themselves. The sashes are what is seen in the video above. The sashes go into the window frame.
You will likely find 1mm high ridges on the outside of the tope sash where painters have painted the windows over the years with this top sash stuck in place. These ridges need to be removed by scraper or sander. Similarly, ridges of paint on the beading taken out to access this top sash will have paint ridges.
Once these have been removed, once reinstalled, the top sash will have free movement once again.
BARS ON THE WINDOWS – EXTERIOR
If you have bars outside on your windows, and plan a paint job, changing the sash cords is the perfect opportunity. While the windows are out, prepare both the sashes and the exterior window frames from the inside before you put the sashes back.
WD40 the pulleys, and you will have a perfect finished product.
