The grout aroudn the tile in the shower/tub stall is cracking. The bottom
parts are worse, and there are hairline cracks about half way up. We moved
into this house in December, and there was no cracking then.
There us one small bit where the grout fell off, and the crack was filled
with silicone beneath.
When we moved it, we found grout patch and silicone in a box. I wonder if
there was damage that they just covered up.
What is my next step? Do I need to pull down the tiles?
old grout so you can re-apply new. You don't need to remove any tiles. It's
not too difficult. The most important part is to seal the new grout. Visit
your local Home Depot or similar place, they can tell you how to do it.
It will. We just had to have our shower torn out. 18 year old grout was
letting water get past it, and water soaked carpet in closet behind
shower got mildewed. I apparently was happening for some time..
If the wall behind the tile is damaged, then the only thing to do is pull
it all out and re-do.
In spite of what some told you, you have a major problem. If the joints were
solid 8 months ago and now they are cracked open everywhere, and on top of
that you discovered silicone in one of the joints that came loose, my bet is
the support behind the tile is wet - maybe rotted, and another patch will be
just that - a patch.
Dang. I think this is the first time I wished we had more than one
bathroom. This will be a project that needs to take 3 days, max. I have no
idea where to start. I thought the tiles looked nice, but I think I'll
look into getting one of those plastic solid piece tub/wall things......and
I'll have to hire someone to do it. It is beyond my know how.
While your removing grout it would be a good time to pull just one or two
of the tiles and check for water damage. The worst areas are usually the
front end of the side wall at the lower levels. If there is damage... you
will notice once a single tile is removed other come off easily!
Good luck! Mike
I have a different opinion.
The last time I did what everyone suggested.... scratch out all grout
and put fresh in and seal it. But in a less than a year, it started
looking bad again. Next time I will just keep touching it up until I
replace all the tile with a solid surface.
If you are going to try to repair and live with what you have, get one of the
grout remover tools that looks like a scraper except the blade is straight in
line with the handle, and the blade has carbide or diamond grit on the edge
depending on cost. There should only be caulking (silicone) around where the
tile meets the tub and up the corners. Where you have the caulk in the other
tile joints, work on those especially well to get all traces of the silicone
caulk out of the joint. Grout will not stick to the tile if not cleaned
really good and to the depth of the tile.
No matter the year. If not mortar, almost surely it's drywall.
Guaranteed it wasn't cementious or other tile backerboard, but some dodo
could have used plywood. Who knows. Have a tile contractor or builder
at least look at it so you'll not have to guess. Or worse yet, re-grout
and then it all falls out in 6 months.
