Hi PETEM, his lime is fine for Lime rendering but not Venetian, not consistent enough for fine quality and has no Genuine authenticity on, point is think of our quarries in the Uk and that of Italy, that's the differnece. Many people call Venetian (Marmorino) that name is a trade name, the rest of the name is on the tub, if it doesn't state that,ie made in Japan lol don't use it. Take it from me, buy the decent stuff and you can't go wrong. Some say it's called polished plastering, it's not, mike wyes stuff doesn't have a zero rating, so when, like the other day my architect wanted to see the cert, I managed to get a copy to prove the product is genuine, you won't get that anywhere else, that's the difference.
