lol sorry mate thats adhesive on the wall tills are going along there and trim on th top the other trim on the other side off the wall and the strip going down are loose cuts of trip the trim has to go all the way around the wall lol any help would be a big help !!
for starters who supplied the trim, genisis do a 10mm trim with 10mm exteral corners to form three way mitres you could try homelux for their external corner range.
ok mate the trim is the black stuff , on the first pic on the left hand side there is tiles going up the wall i have placed trim on top off the tiles and down one side, on pic 2 this is were i am going to be laying tiles level with the other side but need to put trim along both side off the wall thus having a 3 way mitre with out sharp edges and not looking tacky
ok instead of trying to mitre round the angle and without using a three way, on the return do your upright and a flat mitre to the top and butt the return into the back of the mitre the corner wont be as sharp but still not perfect.
I have an idea ,as i can't really see what your getting at with the pictures(must be my browser)cut the trim that meets the reveal square, then mitre the vertical piece and the horizontal piece that sits on the reveal(does that make sense)?
thought about that mate but thought it looked kinda rough mate the contractor is kinda a perfectionist where could i buy a three 3 corner already done ect ect
While you can probably get them ,i have never seen one ,if you trim them top tile down a couple of mm on the reveal you will get it to sit perfect and the contractor should have no qualm's.
That'a how i usually cut plastic tim if they have no corners available
that one was done using a triangular corner piece, made by Blanke, as some others have sugested most of the companies making trim, do a corner of some description
here are some Tilerite ones, homelux do some the same, this style of corner will have to go on the side rather than the top, there is another style avialable that sits on top instead of the mitre.
I would hav tiled that right hand wall first taking a level line from the back wall for a guide. Put your top trim in place cut square to the end of the cut tile before going into the reveal of ....oh my god is that an arch way!!!! then lay your upright trim and top trim in place into the reveal pretty much as you hav now with a flat neat!!mitre on the corner....hav you got a mitre block cos the pic looks pretty rough. I guess you are just working your way around the wall but think you need to reverse your way into the reveal at this point. Because those trims hav quite a flat profile I dont think its gonna create too much of a sharp point I doubt you will get a corner to match that profile...Hope that helps mate...good luck
