Ilia - if you look at the history of Keim paint is was developed to be a substitute for Italian exterior fresco which would standup to the Austrian Bavarian weather. There are pictures of buildings using Keim, in fresco type murals, since 1890 in Switzerland and other places.

I agree fresco can be, and is often applied to a wide variety of schemes. I tried to get a commission for a lobby of a new condo tower called 'fresco' - but got the 'bum's rush' - does that equate into Russian?
