Do you have a tile edge, or is it just tiles then wall?

Personally I'd add a tile edge, even if it's glued. Paint wall to tiles, then glue on a nice metallic strip. They're supposed to be installed as the last tile is being installed, but I'm sure you can get something with the same look.

I don't have a tile edge just tiles, wall with grout between. Not sure if I want to have a metallic strip on there. Thanks for your response

It isn't too late to add a small 'pencil' tile along the top. It doesn't need to be a metal strip. The finishing tile doesn't need to be big or imposing either. I think the trick with doing dado tiling to 1200mm is really finishing it off properly at the top, else it runs the risk of looking cheap as robandlyn suggests.

As said above the metal strip is generally installed during the tiling. I just could not sway my hubby to go with a capping tile in our budget ensuite reno, but in hindsight he agrees we should have.... Anyway, I decided to tape the tiles and paint over the grout as with the darker paint colour it helps it recede. The grout line isn't too noticeable from a distance thankfully, but here is a close up which might help you decide what to do

I have always asked my guys to paint only the top edge of the tile and wipe the face clean with a rag so none of the paint is left on the face or grout. Painting the top of the tile helps to further seal the gap between the wall and tile, making it easier to clean and less likely to provide crevices for bugs and germs to dwell. www.odysseystudios.com.au
