Dang, I'm just catching up on my GSBN email tonight. Sorry we
missed you! Alert me directly next time, will you?<br>
<br>
Paul Salas out of UNM told me about potassium silcate at one
point, and gave me a quick demo as we passed through Santa Fe one
time. He was looking into the same, and I believe he was trying
to figure out if/how it was chemically changing the soil. It was
definitely effective in reducing water problems - he had a small
adobe that had been treated and another of the same soil which
hadn't, and when he dropped them both in water the untreated one
came apart. The treated one came out whole. <br>
<br>
I suspect a brush-on application would help the plaster hang
together as a monolithic sheet. It would also reduce water
infiltration, I believe. Of course, it might also reduce
outfiltration... If it holds water in the untreated interior,
well, I don't need to spell out for you what could result. You're
a smart guy. <br>

<div>I'm trying to help a builder near Austin, Texas with a
delimitation problem on a 7 year old building. He says he has
since learned to use potassium silicate as a brush-on stabilizer
for the blocks, helps the plaster hang on.</div>
