Help: Hanging TV on patio with Hardi Plank

Assuming it’s a lightweight LED or LCD tv, the plywood will hold it. drill a pilot hole through just the hardi board and use #10 wood screws.

Use atleast 6 screws spread across the bracket to spread the load and not risk a screw trying to pull out because I’m sure the plywood is OSB and not real plywood.

Alrighty. Thanks.

The plywood will be fine for these light tvs.

I’d drill a pilot fir sure though.

How long? 1.5"?

The thickest part of hardi siding is about 5/8" and the almost certainly osb sheathing is ~1/2". thats 1 1/8" plus whatever thickness your mount is which I'd guess is 1/8". So 1.5 is just about right with a 1/4 to spare. Like the other poster said, use all the screw holes and the osb will be just fine.

Is there a trick to finding the studs

If your hardi plank was installed correctly the butt joints of the hardi plank will be staggered and will line up on studs

I doubt the Hardi Plank and plywood is strong enough to hold it, right?

Personally I would try to hit at least one stud by going off where the butt joints are but as others have said, toggle bolts through the hardi and OSB/ plywood will be more than strong enough

These for example are rated at 265 pounds each in 1/2” drywall. in your setup the strength would be significantly more

I used these for mounting a tv on hardi plank at my previous house and they worked like a champ

Like this?



I blocked around all my tv/fiber outlets but if not, I would use these.

Where exactly do you plan on him threading the plastic anchor, in a plank that’s 5/16” thick? Or do you expect him to install drywall anchors in plywood?

OP, please don’t listen to this advice
