Re: RE: [papercreters] Re: Petrefied Hessian

Here's the conversion.  (not exact but close enough - e.g. 1 pound = 453.59237 grams so 900 g = 1.984 lbs )

 

original metric	to make an equal amount	5 gallons water to make 3.8 times as much
> 5 liters water	1.32 gal	5 gallons
> 5.5kg cement	12 lbs 2 oz	45.9 lbs
> 900g lime	2 lbs	7.6 lbs
> 450g salt	1 lb	3.8 lbs
> 225g alum	1/2 lb	1.9 lbs

My metric conversion skills are not too good, so could someone convert the recipe for me. Using 5 gallons of water instead of litres and going from there? --- On Tue, 11/30/10, JUDITH WILLIAMS wrote: From: JUDITH WILLIAMS Subject: RE: [papercreters] Re: Petrefied Hessian To: "papercreters papercreters" Date: Tuesday, November 30, 2010, 7:16 AM   I am also wondering what this is used for. I have been negotiating with someone about taking own a large metal building so I could use it for porch roofs but had not heard back from the guy until yesteray. So I thought I would get an old billboard and paint it with something to stifffen it up. Is this the sort of thing you would do with the Hessian?

Could you use it as a waterproof coating for rammed earth, papercrete or strawbale? --- In papercreters@yahoogroups.com, "Wayne" wrote: > > After many weeks of painstaking research I have came across the recipe for > Petrified Hessian as use here in Australia since the war and still used > today, so I will print it here and appreciate any feedback, especially > from anyone that tries it.
