Scrape, oil, and paint windows!
Neglected windows lead to a house becoming old unnecessarily early. It really pays to keep them in good repair. Moreover, it is not particularly difficult with the right knowledge and tools.
When repairing and painting windows, the results will be much more sustainable if you work properly. For example, many people do not bother washing the surface, and instead start directly with sanding – but all they do is to sand the dirt. Others choose to first scrape and sand, and then wash, but which results in moisture entering the wood, which of course should be avoided.
It can be tempting to cheat with scraping, but with the right tools it does not need to be tiresome. A “two-handed scraper” reaches most parts of the window. Then use a small scraper with holster for places that are difficult to access. A scraper with replaceable blades (three-cornered blade, round or pear-shaped blade) is useful when refurbishing old profiled windows.
One important item that is often missed is to oil and prime putty seams before applying new putty. Otherwise, there is a chance that the new putty will not adhere for very long.
New totally unpainted windows should be painted as soon as possible. If a window remains unpainted for six months, the length of life of the eventual paint will be considerably impaired. If the window is old, but has wooden parts that have been bare for some time, it is possible that the wood has become weather-greyed. In such case, it is important to sand away the grey surface. Otherwise, new paint will not adhere.
