Anti-climb paint

When we first moved to London, we noticed signs which say 'Warning: Anti-climb paint'.

It sounds like a silly idea and I have certainly not seen them in Australia.

I did some research today and found that it is actually a non-drying oil based paint. In theory, this should make the surface very slippery and impossible to climb. It also marks people's clothes and skin should it come into contact with the paint.

However, the paint that we saw generally look dried. And I don't think it is going to stop anyone from using a rope to climb in.

Anyway, it seems sad that we have to come up with these kind of measure to stop people from entering a premise. *sigh*
