Most don't notice unless you do something a little out of the ordinary. Venetian plaster (real Venetian as in lime based plaster not that acrylic stuff) always gets the Oooooos and ahhhhhs but you can accomplish similar things with different techniques using normal plaster.
Plaster here is a little different but we regularly tint the plaster or seal it with a colored wax to get a unique look. It's not for everybody but if they like it telling them they don't have to paint justifies a bigger price and makes you stand out from the crowd and is miles better than typical drywall finish. (which is the 'standard' here)
Here are a few examples of what I mean. No paint on these walls. Tinted plaster with a texture and the brownish one has tinted wax. No corner bead so all hand formed corners for that old fashioned look. Last one is Venetian Plaster walls and standard plaster ceiling with custom molding for comparison.
All the best in your search. Just make sure he enjoys the work and the rest will come.
Thanks for the feedback, you've gone out of your way, it's much appreciated.
Yes definately a big difference from regular plastered walls and quite subtle also, not the vivid impact of the venetian (well not in these photos).
I completely agree that venetian on it's own is not enough and leans more towards being a decorator, in my opinion (not that decorating is a bad trade), and having the plastering skill is important. That's the plan and we are beginning to get a good feeling about it.
Sadly you are far away and it would be great if you could take him under your wing, even for a short time to give him the flavour of plastering.... But that would be too much to ask! So I'm grateful for your advice.
All the best to you and your family.
