Beats anything I've ever seen or thought possible.

He makes it look so easy, I almost want to try it myself.

I wonder what makes the mix that sticky? So nice, and to him, it's just another day at the office.

I wondered the same thing. I imagine it's got a high mix of volcanic ash and lime.

I don't think it came out of a bag from the Depot.

[Jim Katen]

The link on the video says this:

Four to five buckets of sand (1 buckets = 20 liters) per sack of lime (one sack of lime = 25 kilos).

Four sacks of lime per sack of cement (one sack of cement = 50 kilos). and multiplied by the portion of sand.

Depending on the thickness of the sand, Sand very thin there is put four to five buckets to a sack of lime. When the sand is very thick you lay three buckets depending on the consistency that you want to give the mixture.

Nothing special. It seems like it's more about skill than a special formula.

I'd have to convert it all to shovels and lbs to know, but it sounds like a high lime mix.

Special isn't part of the equation. It's all sand, lime, cement, and water in varying proportions. Nothing's special, except the guy mixing the mud and placing the brick.

The guys a proletariat Brunelleschi.

I visited a home in Mexico that had those brick domes in more than one room for a ceiling. I assumed they propped things temporarily to get it done but I don't know.

When they first started speeding up the video, I thought he was moving that fast. Damn, him and his partner are good.
