A 6” hole in the exterior garage wall due to a clothes dryer vent that was relocated.
Behind the stucco there was wood.
A 1x wood board large enough to cover the hole was glued and screwed to the existing 1x from the garage side.
This left a depth of about 1.5” to the edge of the stucco finish on the exterior.
A coat hanger was doubled, bent to 90 degrees +- and cut making a 3”x3” +- anchor. A long sheet rock screw was inserted through the hole opening into the wood. This held the anchor.
Some concrete (cement is OK) was placed in the hole followed by a small piece of wire mesh.
More concrete was applied over the mesh as well as inside the toad.
The toad was pushed against the anchor sticking out of the wall and pushed into its seat.
It was an orchestration of movements but it all worked.
Later after the toad had cured, Concrete Fix All over the moistened concrete patch helped achieve a finished texture look.
Chinese bristle brushes or a spray water bottle work well to moisten.
The hooked toad was caulked and primed.
The job took about an hour and a half and at the time, the cost of the toad itself was about $3.00.
