Tiling over quarry tiles

[Bezz]

Why are you worried about rising damp?

Look at the floor you have now....I see no issues with damp in the porch.

Just use a tile that can be used for external conditions.

Tom I agree no damp issues at present. Correct me if I'm wrong, but my concern is that if I add a floor levelling compound, plus adhesive and then tiles, then the moisture that would normally evaporate will have nowhere to go and the levelling compound/adhesive will fail. For info the tiles I have purchased are large ceramic floor tiles.

I don't particularly think the adhesive will fail, but do believe in covering them the moisture could be forced out and up the wall..maybe a natural stone would be better than ceramics

On the photo there appears to be some evidence of damp in the corner immediately above the floor, peeling paint and what appears to be damp staining showing through, also the remedial installed dpc would suggest damp issues in this area.

How do swimming pool tiles stay affixed if damp affected the adhesive?

Some times you lot over complicate jobs.

On a personal note, I like the tiles as is - perfectly suitable for a period porch.

Agree with Tom. Porch looks spot on as it is and in the real world that would probably just be tiled on and last many decades without issue despite the excellent Damp proofing advise that has been given. Sometimes you’ve just got to get on and do these things.

Don’t think anyone is over complicating things, Bezz has indicated a concern re-dampness all advise given above is relevant In my opinion.

Thanks Tom, I agree there has been lots of text book advice but I think I may just go with my original plan. At the end of the day the cost of tiles for such a small area is only £90 so if it fails, then so be it it wont be the end of the world and I can always rip up and start again.
