What's the best white silicon?

Hello

I am looking to apply silicon into the two internal corners of my newly tiled shower alcove.

I want to fill the 3mm or so gap and leave maybe 2mm of silicon on top of the tiles to give a perfect straight line down.

The tiles are a darkish grey colour, and I am finding that my Unibond brilliant white silicon is letting the grey colour through where it is applied quite thinly.

Is there a silicon that would not be so translucent even when applied thinly on top of grey tile?

Anti-mould properties would also be desirable.

Cheers.

If you are applying it thinly over the tiles and you can see the tiles through then it will start to peal where its thin you will need a set of the rubber silicon shapers they shape the silicon in to the corner and leave a bevelled edge. the sets are from JML so woolworths ect they cost around £10 and make a better job than a finger

you can get unibond grey silicone from b&q that might help

when applying silicone inject well into void then spray with soapy water before tooling in and you will get no residue on surrounding surface..

Champion responses, chaps!

Thanks. I got a Fugi sealant-shaping set, and the job's a good 'un.
