latex screed on old quarry tiles.

[a bottle of gin]

hi guys , i am new to the forums and to tiling so please bear with me.

i have bought some 150 year old quarry tiles with what has been described as a latex coating. it looks like a self levelling screed of some sort.

apart from sitting down and chipping away are there any other ways to clean this off?
also , will chipping away at this stuff damage the tiles?

Get a mini grinder with stone cutting discs and buzz out
the material on the backs of tiles. make sure you wear a dust mask
and do the work outside.

thanks murf , the screed is on the face of the tiles and the backs are relatively clean apart from the odd splash of lime screed.
surely a grinder would damage the tile face?

 

[murf]

My mistake, there is a type of grinder called a feinmaster that would probably do the job for you without damaging the tiles.

do you think this screed might be brittle enough to chip off with a sharp chisel and hammer?

thing is i dont mind spending a few days doing it manually so long as the stuff comes off ok.

Hard to know till you go at it. If you have plenty of time then just tip away with a chisel or scraper. quarries are usually very tough so they
should'nt chip too easily once you aren't too aggressive with them.
Good luck with your project

are those quarries 9" x 9"and about an inch and half thick?

hi tel , i think they are 6x6 but they are 1 1/2'' thick.

IMO it is going to be really difficult to get the latex off the face of the tiles without damaging the face of the tile.Personally i think it will be a struggle,just being realistic.

would a chemical remover be more effective perhaps?

If i were you i would grind the leveller off not worrying too much about the face, After you have layed and grouted rent a floor polisher to get a decent finish and reseal .It wont be original but will look good.

It's doable but it will not be the most pleasant of jobs, so heres a brief run down.

Some of the leveller you will be able to remove by pushing a 2" fine paper scraper between the latex and the tile; you can buy these from wickes. This prizes the latex of in sections.

What is left can be removed with a combination of a wire brush/fein carbide rasp and acid. If you notice the leveller is smooth surfaced, so this needs to be roughened up with the tools above and then apply a dilute solution of phosphoric or hydrochloric acid to the leveller. This allows the acid to breakdown the structure better.

Agitate the acid with a coarse scrubbing pad (wearing gloves) the leveller should foam up. When foam dies aways, rinse of and apply more acid and agitate until all gone.

As I said long winded, messy, potentially dangerous and remember plenty of ventilation especially with hydrochloric acid.

Why did you buy them with leveller on? There cheap as chips clean faced

thanks for the info , they are not that cheap cleaned. reccy yards want around 2 quid each or more for tiles like this, can you get them any cheaper? new ones can be cheaper but i will be laying these in a 16th century cottage so i wanted something that wont stand out too much , new quarry tiles might look a bit too new.
but the main reason i bought them was because i got between 6 and 7 hundred of them for five quid.:hurray:

when i bought them though they were described as being coated in latex , i thought this was a water proofing paint and would be easy to clean off.

i knew it would take a bit of work to clean them but i wasnt sure if it would be doable without destroying face of the tiles, to be fair though the tiles are 150 years old so they wont be perfect anyway.

i applaud you but having cleaned 1000's of them I would have paid the £1000 for the recaimed clean ones as opposed to the latex covered ones but if you have time on your hands and your labour is free then you may save a few hundred quid

Hello ..

Chisel what you can off the face of them , then using a variable speed grinder or similar and start with a 50 grit sanding disc and remove as much residue as you can then step up to a 100 grit disc use that then a 200 grit then the tiles will look fine after that...those tiles look more like satillo and should sand back pretty easy...
