I live in a rental property that has a tiny yard out back. I’d love to paint it just to brighten it up a little more for sitting out in the 3 days of UK sun, but don’t want the landlord to take a hissy fit and steal my deposit. So if I did paint it, is there a (easy) way to strip it before I leave? 
The other thing you could do is a temporary something that you can remove when you leave, like a trellis with plants or a weatherproof print of something.
That’s a good shout actually cheers. Will look into something like that.
