Re: Help Concerning Silicon

[tricky_tiler]

After some advice re shower cubicle in the photo. Silicon seal the bottom ... What about the vertical bit? Should I remove grout and Silicon? Or Silicon over the existing grout? Thanks!

Remove grout and Silicon in the corner...and get a grout cleaner while your at it to give the shower sparkle.

Thanks for that.
A lot of the grout appears to be cracking. I have removed quite a bit for the left wall, haven't started on th me right wall yet. If I plan on regrouting it , how much grout do I need to remove first? Thanks again!

Is the substrate/backing behind the tiles plasterboard....

 

[tricky_tiler]

The reason for all of this is because of a slight damp patch appearing in the toilet directly beneath the shower!

How long has the tiles been in the shower area....

I would scrape the Silicon out from where the shower tray meets the tiles and as said the corner and re-Silicon, this maybe only a temporary measure, where your grout is cracking on the tiles you need to remove to the depth of the tile.

There is usually a reason that the grout is cracking, moisture getting into the substrate or if a tubbed adhesive was used causing it to expand or soften up and allowing the tiles some movement.

A re-tile will be probably needed in the near future but as always that would be your choice.
