I just finished painting an outdoor wooden fence with Tambout Varnit. Despite my best efforts, there were some drippings onto the wall underneath, which seems to be covered with some sort of very hard rough spackle and painted off-white. This happened in a few places on the wall (here is one of them):
I am looking for the best way to clean these up. Here is what I have come up from so far:
- Paint: Try to match the current paint exactly. But this will be very difficult to do, and even if I can match it in one place, as the paint has been on the wall for over 10 years and has weathered and gotten small stains differently in different places. Nervous that this will change a small touch-up project into a very large "paint the entire wall" (30-40 meters long, 1.5 tall) project.
- Sand it: Get a coarse grit sandpaper, and try to just touch up the spots with the paint droppings. Nervous that this will either be very ineffective, or will leave spots that are too visible and obvious.
- Scrape it: Get some coarse attachment for a multi-tool or angle grinder, and try to lightly grind away on the spots. Nervous that this will leave some very obvious marks (wounds?) in the wall.
Thoughts on the best way to clean this up?
