Terra cotta blocks were put on sideways
The grooves were supposed to be horizontal to grip mortar. We filled the holes with super-duper mortar
Pebble Dash stucco replaced in Takoma Park
Here's how we did it:
Blocks are splashed with a mixture of 25% flexcon and 75% water.
We used 50% flexcon in the mortar for the scratch coat. This stucco never coming off.
The chimney had been redone, but the top was failing and there was no flashing.
The stucco was cut off at the roof and new flashing put on.
One must be careful with terra cotta chimneys. You can knock the whole thing very easily.
A metal brake is used to bend the new flashing.
We made a several month supply at the same time.
Note how the band hides the joint between the old and the new.
The top half really didn't need replacement.
We made the band with plaster stop.
We replaced the other side up to the roof.
