Sub Contractor Doesn't Want to Apply Sealer to Cerramic Wall/Floor Tile

Are wall tiles normally not sealed, and just floor tiles?
How long must he wait before applying sealant ? He says 30 days after grouting floor tiles, and he does not want to seal wall tiles at all.
Thanks.

The tile or the grout? Unless you have an unglazed tile, then sealing's not necessary. I suspect you mean the grout.
Grout pertaining to floors are usually sealed. For shower/tub, kitchen splash walls it's also a good idea. Wall areas in other than non-wet locations, not necessary.
Depending upon the conditions, weather, etc; 4-5 days is plenty of wait.

PS. Sealing the grout is really a simple chore. Doing it yourself may save yourself a decent chunk of money. Check your local tile store(s) for product recommendation.

Dude we can not see it from here.
What kind of tile? Located? How high on the wall? Water splashes or direct contact?
When I sealed the GROUT on my new bathroom I waited 72 hours. Instructions said 48 hours.

I think "sealing" is a waste of time. It only lasts a few months, and you are not going to be diligent in reapplying. Once you let it go, there's no point in keeping it up.
Grout so-called "sealers" are a recent invention of the chain retailers looking for a high-margin add-on. Places like Color Tile would practically give away the tile to get you to buy an precious kit of installation tools and supplies.

Until a quart of RED paint is accidentally spilt right down the grout line. Because my tile had been sealed (DIY) the paint wiped right up with paper towels and a damp cloth. There is no sign of red in the sandstone grout.

I used a product at the local HD called Stand N Seal (also another similar one), one can does 500 linear feet. Spray it as you walk, absolutely no clean up...dries clear, etc...
Think sealing is not a good idea, huh?

I'll grant you that if spilling quarts of paint is your test, then all bets are off.

Have you ever done a time tested comparison between sealed grout and non sealed grout? or between waterbased vs. lcquer bases, or??? Have you ever looked at enough tile installations to really know? Key word is _know_. Or do you just "think" you know what you're talking about while look for excuses to slam chain retailers. We're not talking about your 1-2 lifetime installations nor a crappo outlet like Color Tile. Are they even still in business??
BTW, most chain retailers don't have jackshit for choices in sealers and carry it only because it's asked for by the consumer. Oh and becausde they sell things genius. OTH, tile supply houses will generally have a wide selection for both the homeowner and pro.
Perhaps you shouldn't 'think' so much. Your opinion as a novice doesn't help anyone.

Grout needs sealer like a driveway needs paint.
