Advice on tile upstand backing

[MrChips]

Greetings from the Uk!

I'm in the final stages of my conversion but need some advice on how to approach the 20cm tile upstand around the room. I've started chopping out the bottom of the plasterboard (drywall) but the board adhesive is proving a pain.





The tiles are 10mm thick and I want them to sit just proud of the plaster/plasterboard (which is 12mm thick).

So are my only choices to chop out the blobs of adhesive, then refit plasterboard backing with minimal adhesive, thus leaving a nice surface about 8-10mm deeper than the main part of the walls?

I'm assuming 3mm wood ply type board would be too flexible?

I ve used 1x4 inch painted wood molding topped with a ogee trim .

I don't think you need to worry about flexing if it is applied to a stiff wall.

I think he's worried about the flex between studs because there may not be any lateral backing between them. However, with the tile, mortar and grout all in place I would think that system to be fairly strong even on 24" center framing.

Not sure I understand your plan/issue....

Does the second picture show a 'sample' of that you are proposing? A tile tilted up, with the existing wallboard chopped out already?

I guess too late now, but I would NOT have done it that way....the exposed joint between wallboard and tile is hard to keep perfect. Id have mounted the tile right on the wallboard, caulked the top edge.

With your current plan, what IS the tile going to mount on? So once the wallboard is cut away, what remains?? I really cannot make out studs, although in one picture I see something but doesnt look like wood.
