A feeble attempt at damp-proofing I'd guess. Maybe someone covered up the floor with lino or a carpet, found it went mouldy, so tried to waterproof the floor with a latex compound.
Fortunately quarry tiles are pretty tough, so after scraping off as much as you can you could try various strippers - the ubiquitous Strippers of Sudbury may be worth a call.
you may be right feltwell about a chemical stripper , ive just bought 600 tiles on a whim and they are described as having a latex coating , doing 600 tiles without the aid of a chemical stripper might be a tad tedious.
so they are salvageable then?
i just got some pics sent and it doesn't look like latex to me (i thought it might be a kind of waterproof paint), unless there are latex screeds out there?
any thoughts guys? have i just committed my self to two weeks of very careful , perhaps futile tile scraping?
Well, at £5.50 for 600 tiles you've got a bargain!
There's a fair chance that a latex layer (if that's what it is) will simply peel off. I've used latex compounds on concrete (waterproofing bridge decks on new road builds) and if you get a corner it will peel off.
Worst case is that you've lost £5.50 and a drive to get them. But I reckon something will take that off.
Edit - just seen your pictures. That looks like self-levelling compound to me - someone's tried to level out an old floor to put carpet down by pouring that gunk all over it, widely available to all bodgers everywhere at B&Q and similar. You can scrape it off, it's not strong and is very brittle. Try prising a filling knife or similar thin-bladed tool under it.
It looks like you've got a latex-based self-levelling compound all over those tiles. It's a b*gger to remove - scraping is the best way, as nothing chemical seems to budge it. Try a gentle tap with a small hammer to see if it crazes; that will make removal easier. The tiles underneath will almost certainly be stained, however. Good luck!
ah , the chipping i can deal with but staining? would a chemical wash such as brick acid remove the staining?
also , would it be wise to take a wire brush to the tiles?
You might find you can live with it. I think it'll be the more pitted tiles where you'll find that the self-levelling compound will be hard to get out of the pits, but it can look OK in a rather rustic kind of way.
When I get a chance I'l post up pictures of my original quarry tiles and the badly laid badly cleaned reclaimed ones in my scullery (not put in by me!) and you'll see what I mean.
Well, according to the seller, the latex "can be removed easily with the correct tools". I should ask him what he recommends Unfortunately, I'm not sure he'll have a satisfactory answer. He's sold these through his 2nd/3rd/4th account with eBay, so isn't expecting glowing feedback....0% since 2005 :wink:
It's a shame you've already bought them, as I'm not far from Lincoln and could've nipped over and checked them out for you before you bid.
I'm hiring a van soon to move some stone. Would it help you if I collected these for you and let you know their true condition and whether or not it's worth you hiring a van to collect them from me? If you decide you don't want them, I'll buy them from you to use in an outbuilding. If you do still want them, you can collect from me...I'm close to Newark, Notts. Of course, this may be no good to you at all as I might actually be further away from where they are now!! Just thought this might help you out, that's all.
Oh, another thought...where abouts are you? I might be able to get my hubby to drop a few off for you, for you to see how easy or difficult it is to remove whatever's on them. Would that help?
