"Huzzah for Young Mike Edison! My only question is, does Jahn shrink 11% or 11/100 of 1%. Would seem to me that the .11% you wrote, Mike, is pretty negligible."
I'd say 0.11% was correct. This equates to 0.11mm shrinkage for 100mm length of patch. Doesn't sound much. But if you have a 2 foot long patch (600mm), then you get a total of 0.66mm shrinkage (26/1000ths inch), or 0.33mm (13/1000ths inch) at each end. A crack of this width is easily visible, and certainly wide enough for water to enter.
