| Here the concrete was real
slick and not very porous. A test is to
splash water on the wall to see if it is absorbed. This concrete
required chipping to rough up the surface
and open pores. The roughing up was done with an electric chipping
hammer. |
Black water proofing must be
chipped.
A bonding admixture is used to bond the new
mortar to the concrete. This is similar to plastering a swimming pool. |

This concrete on this EIFS
tear-off was plenty
porous with open pits and holes, so it didn't
require chipping. An acrylic admixture is essential, at least in the
scratch coat. |
Stucco is a good way to erase
those fake brick you see on new houses.
If the concrete is nice and
straight, you
can get by with a fairly thin coating.
