Rendered soffit boards. Anyone have any experience?

[Mike Wynn]

I was wondering if anybody had any experience rendering soffit boards to a chamferred finish?

 

I have seen the following design online, which I really like but I have no experience using this technique so I would like to know how it is done.

In Australia I did

its a tapered edge cement based board, you use a product from a tub over the joints and screw holes the same as internal plasterboard, but it’s obviously ok for outdoors. 
 

you can get a coloured board from James hardy that uses a joining strip instead of taping the joints.

Yes 

I’ve done this and used a 12.5 cement board Mesh and base coat Then 15 mil top coat Scraped 

You can get the tapered effect using beads
