Mitred edges - 12mm travertine

[lockers]

I have been searching around for an answer to this without success so hopfully somebody can advise.

I consider myself to be a fairly competent diy tiler (it just takes a lot longer!) and I am about to start a bathroom project using 601x406x12mm honed and filled ivory travertine.

I have researched pretty much all aspects before I start but I am still not comfortable with how to approach the window surround edges.

The question is : do I use metal trims or attempt to mitre the edges.

I would prefer the mitred look but not at the expense of an untidy finish. I intend to hire a decent wet saw but am unsure how succsesful mitre joints will turn out.

I have also read that an angle grinder with a diamond cut blade can be effective but cannot workout how a definate straight edge could be maintained taking this approach?

If I go down the metal trim route would the 12mm aluminium trims such as those sold at tile rite be ok with my tiles allowing for adhesive (basic question I know).

Any advice greatly appreciated......

I do neither just extend the face tile past the window reveal about 15mm then bed the reveal tile flush so you don't see an edge standing back looking at the window. How do you mitre if you have an L shaped tile, the metal trims I've used with marble hope this helps.

polish the edges with a orbital sanded before you put them up

OK. So i'm making this more complicated than I need to.

To simply butt the tiles up and polish the edges certainly seems more straightforward.

Is this regarded as common practice then ? Presumably I will need to use some fine paper to finish the edge to match the face of the tile... how close will it match the face?

Thanks for your comments.

good mate just keep it steady try to pick out the good edges

or just use 9mm plastic trim (12mm will overlap too much), in cream or ivory and fit it level with the top of the tile. if you're going round the window always make sure the trim is fitted under the tile, and mitre the corners.

I think this way looks better.Trims with Trav not very nice,makes it look cheap.

Big NO to plastic (or any) trim - it looks awful with natural stone.
Definitely would use the edge of the tiles as described earlier. I've done this in my own bathroom and it looks nice and "authentic"! Can post photos if you like?

Mitres are tricky on travertine, especially if it is slightly crumbly.

Hello chaps, some of the answers are nearly correct though not quite.
YES - the best results are acheived by butt jointing and polishing the edges.
HOWEVER - The way to acheive this is as follows............

You need a variable speed grinder ( I use a Makita )
& also a velcro sanding pad attatchment and sanding disks.

The idea is that you should sand and slightly round off the edges prior 2 fixing and then give a final light finishing sanding once the tiles are set and adhesive set. This way you do not do much unnecessary damage or sanding to the adjoining tiles.
Slow your grinder down to around 1400 rpm ( or speed setting 2 )
Start with 60 grit, then 80, then 120, then 300 and finally 500. Fix tile & continue with next. This will give a beautiful polished edge. Gently sand again in situ' once adhesive has set to even out.
I will upload a few pics of a job I recently did when I get time.
Faliure to use a slow speed or faliure to gradually go through grades of paper can cause scorching or poor results.
