Yes, Bob, I can't tell you how much you have helped and possibly kept
us from making some bad mistakes down the road.
Right now, we are in very early experimenting. We do hope to cover
the barn for cosmetic reasons more than anything. Right now, all I
am doing is grabbing a couple of handfuls of each mix, squeaze a bit
of the excess water out and smear it on the barn to see if it would
stick. These last two mixes stick much better than our former
mixtures.
You explained very clearly why the two walls shrunk away from each
other. We put $450 worth of gravel in our barn. Rains have been
washing the gravel out from under the walls so we have been mixing
experimental batches of papercrete, different formulas, and currently
with no other use for the papercrete, pouring them in a crude mold
around the edge made from a 2x6 either nailed or just held in place
by some concrete blocks. Hope that explains our current crude baby
steps.
However, if you hadn't said what you said, we probably would have
made the mistake of using it for the entire structures to cut down on
water problems. Thanks for directing our steps away from a big
mistake there.
Connie
