Wall mounting TV to concrete+drywall

Hey guys,

Looking to mount a 55 inch tv (49 lb) to one of the condo walls, which is concrete with a drywall layer on top. Any thoughts on how I can go about doing this? Most instructions I was able to find online refer to strictly concrete/drywall/wood walls.

Thanks.

Are you sure the drywall is secured directly to the concrete and not metal/wood studs between? Sounds like it would take forever to hang drywall on concrete.

If the drywall is indeed attached to the concrete wall directly, I would imagine you would use the same technique as you would hanging it directly on concrete. Just make sure the lag bolts/anchors penetrate deep enough into the concrete.

Tbh I am not sure, construction is not my forte :( . What I have seen is the thickness of the drywall - 1 to 1.5 cm tops.

Pretty sure you can just hang it as if it is a concrete wall (this is what we did at one point), but I am not an expert ...

You need to do a concrete wall installation with the weight that you got, you will need to use a drop-in anchor (best) or Lag shields.

1cm drywall? I think you best check again, not sure if you should be trying to do this either.

To drill into my older apartment concrete walls I had to rent a hammer drill from home depot. Even with that..it was a pain to drill into the concrete and I wasn't even sure if it was working at times.

Very frustrating!

yeah, go to HD, you'll need some really long lagbolts and a very good bit + decent hand drill (won't burn up and decent torque).

That being said it won't be too hard, but you'll need some patience. I installed a heavy gate door and it took some time to install lag bolts on the side of my brick home.

good luck!

I would say standard Tapcon concrete screws, 1/4 or 3/8 inch diameter and 3 inches long would be perfectly adequate for the job. I think concrete sleeve anchors would be overkill.

By the way, yes, you will need a hammer drill. I have one and it, along with a masonary bit, should drill through concrete like it was butter. Slowtyper, are you sure you had the drill on "hammer" setting? Hammer drills have a setting for no impact function so they can be used as a normal drill - maybe that's what happened to you.
