Bathroom tile grout Sealant

[BangkokBoyJohnny]

Hi

 

I've just had my bathroom walls completely re-tiled. 

I (think) I should seal the grout, especially in the shower area.

(Various discussions on the web about if you should or should not !)

 

I've seen some TOA products (200,213, 214) but they're more general tile sealants not specific grout sealants.

 

Any tips ?

Thanks in advance !

What's below the wet room ? If it's on a concrete slab on a ground floor then do what you want. If it's sitting on wood, or in a multi-story building where water damage may occur and you have liability then you'd probably want to seal the grout and the tiles (and plan to reseal after several numbers of vigorous cleanings).

 

When I lived in the US we rebuilt the house with a 360-tiled open bathroom shower. The contractor put down vulcanized rubber, concrete, thinset, tile, grout, and sealant. I thought the whole thing was over the top, but it was all included in a set fixed price so I didn't complain. Though it definitely has outlasted the grandmother unit where the toilet leaked into the two-layer plywood subfloor and the toilet eventually fell through the rotted floor.

If you need to seal the grout you used the wrong grout.

I'm really no expert on grout, or tiles or DIY actually, just that there's a lot of articles out there saying even bathroom grout should be sealed !

grout (when done correctly) it's already a seal, post #3 says it all

I never heard about this but perhaps it is a good idea. Are there any reasons why you should not do it? Can you use the usual tile cleaning products afterwards?

Grout sealant can mark your tiles !

Grout sealers in my experience are a short term limited usefulness product.

If you really want a non absorbent grout then have an epoxy grout installed.
