New Built - Floor Tile Grout "disappearing", to regrout or to just seal otherwise?

dsab

We bought a new built house around 2.5 years ago and got all Bathrooms fully tiled from floor to ceiling.

Over time the grout around the outer floor tiles (where floor meets wall) has cracked and in parts disappeared. We now have a gap of a few mm between Floor tiles and the wall. We knew this would/could happen, but as it looks unsightly I would like to tackle it now.

Would it be better to refill it with grout or to use some other sealant that could potentially hide any further movement in the future?

I have had 2 opinions/recommendations so far, and both were advising very different approaches.

Any Input would be much appreciated.

Is there a skirting board fitted.

If not, would fitting skirting boards on top of the tiles solve the problem?

I don't know if that is good practice or not as our bathrooms are carpeted.

If not skirting board, perhaps a small quarter profile trim colour matched to the wall or the tiles might work.

Colour matched silicone should have been used on all corners.

Mapei Mapesil will do the job

Do not fit skirting boards, timber has no place in a tiled bathroom

andyhop is right.

You need to use a good quality si
Icone sealant.

Thanks for the feedback. Much appreciated.

Is that something that can easily be done DIY to a decent Standard, or should I get a Tiler in to do the job? I would want it to look decent, as I generally hate to look at botched/half arsed DYI jobs. :mad:

A tiler wont he interested. Its a handymans job. Or for a pucker finish get a professional mastic applicator to do it.

A bot of overkill maybe, but I've done this using making tape, then siliconed - remove the tape whilst wet and gently re-smooth - you'll get a decent finish
