Some of the windows in the South side of my house have wooden frames and sills, and on the outside of the house, most of the paint has flaked off, leaving bare wood that is severely sun-baked and weather-beaten, yet thankfully, with almost no rot. I have recently bought this house and I now want to paint the external side of these frames to prolong their life as much as possible. What is a good primer to use? What soaks into dry wood well, and stays put, even over the duration of a long hot summer or three?
I'm under the impression that aluminium primer is good. I guess it must soak into dry wood well, because it is very runny, compared to other wood primers, some of which have the consistency of cheese spread! It seems to cost more than other primers, which also suggests to me that it might be particularly good for some applications.
Anyone got any strong opinions on this?
