They told me to do it. "Cover the walls"!
"Everything green needs covered!"
If you know about Venetian Plaster you will understand that it is not cheap. I don't know how they do it but it looks like they have skimmed the walls with different tones ( color ) of sheetrock mud with short slashing motions, from what I have heard about six or seven times and then they do something to it to give it a smooth finish, almost like lacquer on mahogany, after the 400 grit. I will try to get some pictures of the Venetian walls I did not cover. Yep, my job to cover about 12 - 4' x8' sheets worth of Venetian Plaster. Can you guess why?
