buff yellow floor brick pamments , buried under latex screed for 30 years.

[a bottle of gin]

hi guys. ive found my original kitchen floor in my cottage. it was buried under a latex floor screed for 30 odd years. it is made from yellow floor brick pamments (or it could just be yellow bricks).
anyhow , they look like they have been sealed over their life time and have dulled down to a gray colour , this could also be because of the screed that was poured over the top of them. in fact , thinking about it its most likely the screed that has stained them.
the pic shows the floor brick and a clean pamment beside it to give you a rough idea of what they should look like.
any ideas on how to clean these is most welcome , ive tried scrubbing them with a metal pan scrubber with no joy.

it looks like a honing job for Enduro

I would think Terry Cottar will be the man for this one. He will be along shortly.

Its where the top layer is skimmed off with a special machine usually by the use of daimond pads.

[Gazzer]

I wouldnt think so

Looks like a grinding job to me. The is a specialist job, and would need a site visit to confirm if it could be done. What area are you from? This is the guy i would contact for advice. Kevin 07770598855

cheers, im from flimwell , just round the corner from you.
the floor bricks are in suffolk though.
the other problem is they are no longer on the floor as we are putting in underfloor heating , this is why i was wondering if they could be done by hand.

thank you , very kind of you to offer fella , they are all up in suffolk apart from this one but its now clean, .
i did read that acetone removed old sealant so , being bored i decided that as acetone is an ingredient in toilet cleaner and as tescos are doing a 3 for a quid deal on harpic i decided to try some.
i soaked the brick in water then left the harpic on there for around an hour. a scrub with a pan cleaner and hey presto , the gray gunk , whatever it was came off. not without a fight but it did shift eventually.

what do you think guys? will sealant remover work if harpic toilet limescale remover worked?
