Hardie backer onto osb - Tile Advice

[Dickthedark]

Have a job where walls are clad with osb ( trendy). Customer wants walls partially tiled around all the worktops with larger splashbacks behind cookers and sink etc. As the walls will be partially tiled you will be able to see the top edge and side edges. I am using Hardie backer 6mm on the osb. How on earth doni trim the edges without showing the Hardie backer behind. Customer does not want me to chop out osb and replace wiyh backer

One large trim behind hardie to cover both hardie and tile, or 6mm trim behind Hardie and second trim behind tile

Thanks for reply mate. I thought about a big trim behind Hardie just concerned on availability of 18 to 20mm deep trim. Also checking i wasn't being rough as I'm fairly new to it all. Good shout on two trims as customer is buying the tiles and being mega indecisive so i don't know how thick they are yet, i think that might be the most flexible solution. Thanks again for the reply.

Customers, gotta love them 😂 , personally Alberts suggestion and use flat edge trims.

Thanks for the replies all. I think two trims seems to be the way to go. I will try my best to steer them towards flat trim. Thanks again.

Needs to be flat edge to look anywhere near tidy.

I will make it quite clear that that is what will look neat and tidy and anything else stands a good chance of looking poo. After that its up to them. It's their money after all.
