How do i age york flags?

[nathanphoebe]

I needed to replace some old york flags after a few broke when lifted for a drainage problem.

Had to replace the broken ones with new replacements as I can't get reclaimed locally.

The new replacements have an identical riven surface. And after pointing, the machine cut edges of the new against hand cut of the old didn't show up.

So the only problem is the clash between the dark coloured old against the much lighter new. Is there a way to artificially darken the colour of the new?

dunno about yorkstone but i have used this technique on brickwork
take 1 part green sheep poo and 1 part soot from a fire hearth
mix into a poultice
like an angel delight consistency
then apply with a paint brush
leave over night,was off then apply more coats till colour reaches the desired darkness
another way is to use live yoghurt ,but i have never done it this way

we use horse or cow poo mixed with water and applied causes the stone to age and moss up quick.

we might have one sunday morning taken down a stone bridge buttress on the railway line and rebuilt it at a more favourable position to allow easier access, was painted in said mixture and within a week of so you couldn;t tell the difference. or i might have been dreaming if network rail are reading this.

sheep poo and soot gives a nice patina
theres probably a chemical element at work
but its the results that count

As above - have used horse shit+water paste - on section of new clay peg tiles on roof - to try and blend in with the 200yr old tiles.
Took about 3mths - but now you can't tell.
As a general observation - everyone with their new patio seems paranoid on here about keeping it spotless - went next door yesterday - their injun stone's been down about 6 years, looks like it's been down about 600 - looks great - that old aged york stone look. I guess it depends on the period and age of the house ?
