To silicon or not to Silicon, that is the question

do not grout then Silicon over the top.

Exactly the way I read it, all internals are movement / expansion joints, if you have grouted now and then Silicon over it, what is going to happen, the grout will still crack, the Silicon seal may / will fail and then you have trouble.

Oh well that's that ballsed up then! :sad3:

Will have to Silicon over top. The problems I had with the shower in the past were due to the fact that the plasterboard behind the tiles got wet and fell apart. I was hoping the aquapanel would prevent this happening even if the grout failed and it got wet.

With mosaics, I would use clear Silicon in the vertical corners (carefully scrape out the grout with a grout rake first) and white Silicon for the tiles to shower tray (again rake out grout between tiles and shower tray first).

A quick Silicon tip:
Use a very greasy washing up / water mix to smooth off a fine bead of Silicon and your Silicon will look tidy and shiney.

Good luck,

Daz

And there's another thing, many people think Aqua panel, Hardi Backer are 'waterproof' they are not and do not claim to be, they will allow water to pass through them without breaking down like plasterboard.
