Summary: Drilling into cement stucco can be done successfully. Beware drilling into EIFS, synthetic stucco. You could void the warranty and damage to the finish when doing stucco repair.

I have a stucco exterior from the 1920's, and I have been told that it has metal lathe underneath. I have not been able to drill into it--I have tried a masonry bit.

How do I drill through the metal lathe?

William,
Either your bit is dull or you are not pushing hard enough. Rent a rotary-hammer drill. It will do exactly what you want to do, including going through the metal lath.

I want to put up wall lighting fixture on my cement stucco wall but not sure if I need to cut out a 4" hole to put the fixture box or to just drill a 1/2" hole through the stucco for wire and just use a thin ceiling box on the exterior wall hold it down with screws.
What would be the proper action?

Edward,
You can do it both ways so long as you follow all the steps in the National Electric Code.

Can I tell the difference between regular stucco and EIFS? We just purchased a home that was built in 1994. We have been given a decorative flag to hand from a pole. I considered securing the hanger to the stucco, but it just does not feel "hard as a rock". How can I be sure it would support the flag?
