What's the most effective way to mount a TV to hardie board? I'm looking to mount a TV on my back patio wall and it has hardie board siding (concrete siding).
Kinda tricky... you are going to need to mount it to a stud. I think once you drill in to the hardy board it will cause there to be cracks and it wouldn't lack the strength to hold a tV.
I'd recommend looking to do a TV suspended from the ceiling.
