Tiling Over Red Quarry Tiles

[andynicklin]

My kitchen has red quarry tiles laid back in the 1920's when my grandfather built the house (just thought I'd share that with you!). They're in good condition, no cracks (bit odd chip), and lead seamlessly into the hallway with some lovely patterns of black and white tiles. They're looking a bit tired though, and dull, so I thought I'd lay some new one's over them. I assume they won't need a sealant applying before tiling, as by their very nature they're vitreous anyway (I think that's the right word). I'll be putting the original wooden strip back in the door frame, so the new difference in height won't be noticeable.
As for the black and white tiles in the hall, any recommendations for cleaning them to bring out all their glory? There are a few recommendations I've seen on other threads, but nice to get updated advice!

be careful as it may not have a damp proof course

My first thoughts are to clean and enjoy the quarries. Can you post any pics to give us a clue as to the actual condition of the existing tiles, please?

i wish people would relise what they have got on there floor, old quarries will clean really easy , . i love to finish with boiled linseed oil and white spirits brings the floor back to life , just love the traditional route for the old quarries.

Agree could look good restored but if you really wish to tile over you will undoubtedly draw some soluble salts through if you clad over them when there is no dpm.

1 Clean and degrease
2 Apply 2 coats of Mapei Triblock P blinding the second coat with kiln dried quartz
3 Fix in Keraquick

They're under a kitchen carpet at the moment, but I'll be taking up at the weekend. My only reason for doing it, was that although they're in good condition, they just look dark and don't really go with what I thought would be a nicer theme. I'll take some pics snd post. Cheers

I'll certainly try that on the black and white tiles in the hall. visitors really admire them when they see them. Thank you! Andy
