What kind of settings did you use for what I presume is .6/.8 SS plate?
I built that house for a typical farmer, I told him it would require proper lime putty type mortar, and lots of it.
He wouldn't pay the asking price for that, went off and made a few phone calls to some experts and suppliers, came back insisting hydrated would be fine.
As the whole job was on labour only daywork there was no risk to me if it didn't work.
I was surprised that it set up fairly quickly, much quicker than I thought it would.
The house was built in 2001 and still looks fine, and he field picked the flints for free.
Consistency's a tiny bit too sloppy, needs to be firm enough so it holds the flints up but doesn't mess the surfaces too much. Don't do too much at atime or it might slip down, no rush.
The one on the left, the 1 lime : 1.5 sharp : 0.5 soft (for colour), although more of a mortar colour, well it seems softer and you can gouge it with your nail easier.
I'm wondering if there's an option to up the lime content (if that's what increases strength) but still make it less white?
Hope that makes sense!
Or should I just give the samples a few more days to dry out as in will everything just get harder with time?
Check my first post on this:
'use a stiff mix using sharp grit sand around 2:1. For a yellower look add some builders sand'
Your mix is different, add yellow not substitute for grit, which might make it a bit fatty.
However it's all a bit suck it and see, no hard and fast rules, cos materials vary around the country.
Drying takes time, lime work is slow, one of the main reasons it went out of general use.
Apart from that carry on have fun!
