Bad stucco re-done
in Chevy Chase

bonding cement to concrete  A close up view shows the sloppy work that was here-there's a lot going around these days. The surface had rough spots and slick spots.  We first coated the walls with
a bonding coat of flex-con and cement mortar.
Flex-con is a bonding ad-mixture used on plastering swimming pools, concrete repair and other uses bonding cement to concrete. We used it here to assure a good bond
and for crack resistance..

The original mortar was put on tight to the roof leaving a ragged line. A straight line was defined by using a casing bead. Here is the finished wall. We used a 1/4" casing bead and a thin brown coat and a thin finish coat. The existing stucco was
about 1/2" thick, so the total thickness is about 3/4".
A bonding coat was put on first A heat tent allows work to proceed in cold weather. We leave the walls covered with plastic for about 5 days after we finish. Failure to do this can reduce the color retention. In other words, we don't take off the plastic until the mortar has set up for a few days.
A bonding coat was put on first and roughed up using a rubber float. This gives our finish a good bond.  A heat tent allows work to proceed in cold weather. We leave the walls covered with plastic for about 5 days after we finish. Failure to do this can reduce the color retention.
