[Greenbuilding] Salt and Concrete Sealer-flavoured Chips, anyone?

[Sacie Lambertson]

This sounds like the product Xypex which we used for all the concrete walls
in our house (not the stucco though).  I think it worked.  We very
occasionally will see some moisture only at the seams of the walls in the
storage area.  Xypex is 'painted' on recently poured concrete.  Have no idea
of its breatheability though.  SL
