How to mount a fixture on uneven stone or stucco
Uneven stone and stucco prevent fixtures from making a flush connection. This forces people to guess whether they should flatten the wall, use large lags in the mortar, or drill into wet epoxy to fill the gaps. Building the mounting area out is another workaround, but it can push items like TVs too high if they cannot be aimed downward.
