Cob: Re: spaying lime and white cement

[Patrick Newberry]

Well Grace, I think it's the same list, just a bit hot out is all....

I figured I'd give a report on my texture gun sprayed cob wall. 
You see I purchased this texture spray gun that runs off a air 
compressor. 

I mixed some lime putty with some of my Georgia red clay and a bit of 
sand. I had to make the mix more watery than I normally use for hand 
plastering because the gun kept jamming up otherwise. 

The wall turned out nice however and had a nice finish.  I did spray 
the cob wall with a mist prior to using the lime spray finish.
It had a sort of peach color when the red clay was diluted with the 
lime plaster. The man advantage is that it can put a thinner coat than 
I could have done by hand.

Oh yea, I used some white cement to seal and water proof my 
ferro-cement roof (over the dome). It really looks nice and it is very 
very white. It was quite economical, as it was about 10 dollars for a 
96 lb bag and it took 1 1/2 bags to seal my dome (11 ft radious)

As anyone else done anything with the white cement which from what I 
understand is not really a true cement.
