Are you supposed to caulk your grout? (Bathroom tiles)


Total newbie.
Grout is the cement between the tiles.
Caulk is the rubbery compound.

My bathroom was redone 10 years ago.
The tiles were never caulked.

Should they have been?
Are you supposed to put caulk in between all the tiles?
Or just between the tub and lowest tile? (Tub ridge)
The cement between the tiles (esp, on the floor) could use a cleaning.
Should I just caulk between the tiles?
Both on the walls and the floor? Or just one?

The grout should be sealed with an appropriate grout sealing product, I use a spray product whose brand name escapes me at the moment. Grout should be re-sealed every so often as well, see the label on the product for specifics.

Caulking should only be necessary where the tile meets the tub, and any other gaps where the tile meets something that isn't tile. Also around the edges of the tile, assuming it doesn't cover the entire wall.

Ok, so don't use caulk to cover up dirty grout.
I will just scrub & bleach it, and then get grout sealer.
What exactly is grout sealer? A clear coat to keep it clean?

That's exactly right. The sealer is some kind of clear coat that penetrates the porous grout and keeps it clean and waterproof.

When the grout is badly stained, you may need to scrape it a bit to get the stain out. A grout removal tool (narrow, diamond-coated blade with a handle) works great to lightly scrape away the staining. If the staining is too deep, you may have to completely remove the grout from that area and re-grout. It's not that hard, but hopefully you don't have to go that far.

You use grout cleaner to clean grout. Any home store will have it in the tile dept.
Grout is not water proof. A sealer help keep it from soaking up water and makes it easier to keep clean.
If there's missing or crack grout the old needs to be cut out and replaced.
Caulking is also used on any inside corners.
Any place it changes direction or meets a dissimilar material as a rule.

This is the sealer I've used the most, I think: http://www.homedepot.com/p/Custom-Bu...5#.Un2GL6rXxhE

I've used this grout cleaner a couple times: http://www.homedepot.com/p/ZEP-32-fl...6#.Un2GiqrXxhE

It seems to work fairly well. I did a lot of rental property maintenance, so typically by the time we were cleaning the grout it was way too late for chemical cleaners, which is why I suggested the scraping.
