Mitre External Corners in Porcelain Tiles - Tile Advice

[cornsack]

Looking to do a few mitred external corners this week (600x300x9 porcelain). Practiced the cuts a few times and very happy with that. Never filled the corners though.

Seen some resin recommendations but most of them are looking difficult to source. The only viable option I can see is Akemi PolySoft from Apex Grange but its £15 delivery if I want it in time and I don't need anything else from them. Would still purchase if the experts think this is the only way to go?

Why is silicone generally not used? Is it simply because of the finish and difficulty shaping (it can't be rubbed down). Are so-called 'flexible' grouts really not flexible/strong enough to use in an ordinary bathroom scenario?

@GaryTheTiler @3_fall @LEE MAC seem to be the mitre-pros. Sorry if not noticed anyone else!

Not sure if I’ve mentioned it or not, I have two videos in my albums that may help you.
Good luck.
Look at titles, they’re listed back to front. 🤷🏻‍♂️😊

Mitre and grout,

 

[acaciaguy]

Brill. Thank you. How thick do you get the edge so not brittle or sharp

 

[J Sid]

1mm to 2mm

Where are the mitres being placed?

Small bathroom. There are a 4 external wall corners, tiles will be half-height except in the shower enclosure

 

[Dan]

Half height. I'd consider a trim maybe. Naked bodies and mitres aren't wise when somebody is awesome at them. Let alone first-time-mitres.

You got any spare tiles to practice on maybe, if the mitres are a sure thing and have to be done, at least give them a really good bash on some off-cuts first. Get the hang of it?

I've never done them. And I don't think I'd like to. Kinda for the same concerns you guys have. I'd hate think I've jabbed somebody with my sharp mitre.

They don’t need to be sharp mate, depends how they’re finished.

Have a look at the Schluter website, they have Finec mitre trim.
You still need to mitre the tiles but the quality of mitre required is much more forgiving.
They leave a small rounded edge on the corner and come in about a dozen colours and to suit tiles 3.5-12mm thick.
A great way to get in to mitred corners.

I know mate I just meant if they're the first I attempted, I would be worried that they might end up being. The same as somebody else said further up the thread.

One done right obviously wouldn't be sharp.

Wow. Have got the mitringitself down but filling a mitred corner really is a dark art, can't get the full answer anywhere. Have asked myself before and seen many other posts where the question is half-answered. I have many great time-served plastering (and other trade) secrets I could exchange. Hell I would pay someone for solid answer at this point.

- Are so-called 'flexible' grouts really not flexible/strong enough to use in an ordinary bathroom scenario? I would imagine they could be rubbed down to a perfect shape once dry.

-Are there not any easy to purchase coloured-resins one would use as standard?
