Grout in pores of ceramic tile - To seal or not to seal?


I am finishing up a bathroom remodel using 12x12 Lowes Rialto Noce ceramic tiles. They are very pitted and porous, but are NOT natural stone.

After i grouted everything the grout stuck into all the pits and pores of the tile, but i kind of like the look (very "old world" looking)

Anyway, i am going to seal the grout lines this weekend but need to figure out if i should seal the entire tile. Will the grout stuck in the pits eventually wear away from splashing water? The only reason i would bother to seal the entire tile is because i want to "preserve the look"

I'd hate for a few years down the road for all the grout in the pores to have disintegrated or what not. But at the same time, i'd rather not take the effort to seal the entire tile surface if i don't have to.

Thanks for any advice. pic below

the glazed ceramic tile won't seal. but you will be sealing the grout. depending on how deep the pits & divots are depends on how the grout will hole.
but sanded grout won't usually hold up too long in slightly pitted tile, but hold up good in the Travertine real Noce marble.

I've used Rialto tile and you're right, it is pitted. However I don't think those pits are big and deep enough for grout to bond well in them. I'm sure that in time, with normal cleaning, it will eventually come off. That may take a couple years but I'm sure it will happen.

Think of it this way, today you have old world charm. Two years from now you'll have a whole new look...for free. Deals like that are hard to find.

just finished up laying the beige version of this stuff. working it over well with the sponges gets most of the grout out of the pits/voids. Afterwards a nylon "toothbrush" works fairly well. The real stuborn specks I used a dental pick to dislodge what appeared to be just chalk, no sand that I could make out. After that, I suspect the renter's broom will get whatever is left.
