I thought fly ash was also
a safety concern due to the content of heavy metals, yet people use that in
stucco at times..with caution probably, right?
K
ps. I tried asking
before, but nobody gave me a solid answer....for the recipe for portland cement
stucco. Is it 4:2:1 Sand:Portland cement powder:lime, along
with a squeeze of dish soap.....and water (of course) to desired
consistency??? How does that sound?

Portland cement mix burning to the bone? Whoa, am I misreading,
or just
possibly dead and haven't noticed? I've poured enough concrete
over quite a
number of years to be able to swear I can hear the truck
leaving the cement
plant 1-1/2 miles away and feel it driving down the
road while I am
frantically driving the last stakes. I have been up to my
elbows in the
stuff, jeans soaked through, etc., spattered and splashed
onto my face and
eyes. I've poured in cold weather, hot weather,
everything in between. I'm
not missing body parts (ok, brain may be
slightly damaged) or skin. The
worst I have ever felt is mild discomfort
which has been relieved by washing
up.
I don't doubt anyone else's
experience but I wonder if I am hearing the same
thing that others are
talking about? I can't see that a standard
sand/gravel/portland
cement/water mix is remotely hazardous or anything
beyond "not recommended
for prolonged skin contact." But again, maybe I'm
not catching the
argument and would be happy to be corrected.
