Cob: RE: RE: Sealing cement roofs

They were not using it for an inside application, only on the cement roofs to seal. I'm belive it would dry reasonable quickly.  Of course it might be a bad idea, still investigating, of course there are a lot of things get done by  rich educated folks in first world countries  that should not be immiated either, just to make a buck :-)

Not only is it not very natural but it sounds like cancer just waiting to happen. 
I'm sure there are plenty of things the uneducated poor do in third world countries 
that involve the use of hazardous, cancer causing materials but is that something we 
want to immitate? They probably still use lead based paints to cover their interior 
walls too. Don't gamble with your health just to save a buck. :)

I know this isn't very natural, but I heard about some cement roofs being sealed in Guatamala using old styrofoam and gasoline. Mixed to gether I guess it melts the styrofoam into some type of a substance that can then be painted on to the cement and seal it. 

This is currently being used on habitat homes in Guatamala. 

Has anyone else heard of this. I'll be putting a ferro cement roof over the outer section of my cob house and have been looking into fibers (looking at steel and fiberglass) to try to keep it as thin as possible since I am building by hand and must carry the cement up to the roof.
