Help - how do you get undercoat off quartz tiles?

keystone

No I don't think it would have been risky. As I said quartz tiles are not porous and its easier to pick (but not scrape as quartz scratches very easily) off a larger dried lump than a thin smear.

Are you absolutely sure about that?
I was about to say that if they have stained it's because they weren't sealed correctly in the 1st place.

And having just checked it seems there is mixed opinion as to whether they do, ;)

Yes I am. Well let me qualify the statement. They have very very low porosity actually such as to be insignificant. Can't remember the exact number but is of the order of the third decimal place or lower. Quartz tiles do not need to be sealed IMO.

IMO, :D, always a safe bet.

I think I'd edge my bets and seal though, bit of insurance or a waste of time depending on your point of view.;)

Seems it can be etched by hydrofluoric acid, though but not much else.

Quartz worktops do not need sealing. As for hydroflouric acid, I'd worry more about my skin, flesh and bone than the worktop.

But we aren't talking worktops here fella, thats different.

Quarz floor tiles can be manufactured ie reconstructed quartz and often only contain about 90% quartz.

A quick quote from a a tiling forum website;

Does the quartz tile have a water absorption rate?

Yes the quartz water absorption is as low as 0.2%

What are the DO's and DON'Ts of Quartz?

• DO clean up spills immediately to minimize damage to your stone.
• DO use trivets or mats under hot dishes and cookware.
• DO use place mats under china, ceramics, silver and other objects that can scratch your stone's surface.
• DO use coasters under glasses, especially if they contain alcohol or citrus juices.
• DO clean surfaces regularly with StoneTech™ Professional Revitalizer™ Cleaner & Protector.
• DON'T wait to clean up spills on stone.
• DON'T use cleaners that contain acid such as bathroom cleaners, grout cleaners or tub cleaners.
• DON'T use vinegar, bleach, ammonia or other general-purpose cleaners.
• DON'T use abrasive cleaners such as dry cleansers or soft cleansers.
• DON'T use alkaline cleaners not specifically formulated for stone.
• DON'T use scouring powders and abrasives because they will scratch the surface.

Not etched by most acids, but can be etched by hydrofluoric acid! Because quartz is quite hard, it can be cleaned at pressures up to 1,450 PSI if the grout is in good condition.

Maybe the op can shed some light on the issue, ie are they natural tiles or manufactured?, either way it sounds like spirit from the paint has got into the tile, and if that's correct then anything used to clean it off will do to, which is the worry he has.;)

Unless I've missed it I have seen no evidence or statement from the OP that his tiles are stained as a result of this spillage. Gizza pointer huh?

My name is not 'fella'. And as said by Keystone, can't see where the OP says that paint has soaked into the tile.

If it were me, I'd keep a sample of the tile as a tester, so that I can use various cleaning methods on the sample, before using them on the real thing. Even buying a sample might be worth it, if there is still an issue, and if not, just to get one in while the particular tile is still available, for future use.

Finger nail is always a good idea, or a hard plastic scraper, something softer than the tile. I suspect my suggestion of a glass scraper would work, when used carefully, but I must admit I'd want to test it first on a sample, which I'd do with white spirit too.

So why can't he get the stuff of his tiles?, you simply can't accept that the tiles may be reconstituted quartz can you?, which would explain the issue, op will not know even if he installed them himself as they are sold as quartz, blanket fashion.

If it is surface you simply scrape it off as suggested by all, if it won't come off, just maybe/obviously it has gone deeper.

Or shall we call the op an idiot as it's easy to clean quartz?

Doesn't become your usual sensible self, but I can be persuaded otherwise,

Sorry, ignorant reply suggesting you read the froggin post before commenting, fella,
Get real and cut the carp about keeping a sample etc, he didn't/hasn't hence his problem, if you have a practical solution then voice it but methinks any attempt with white spirit
or similar is disaster bound, but of course, you don't need to seal quartz.

The op likely doesn't know what the tile is so any comment about quartz doesn't stain is irrelevant unless you know better.
