Drive railroad spikes through the masonry with a sledgehammer. Make sure you get a good backswing going.

simply so they are not liable for improper hanging...tapcons (masonry screws) should be plenty,drill the proper size hole and do not overtighten.


I'm still thinking that these might be okay for a flat mounted TV. But for a full motion mount that is holding a 65" TV extended 28" from the wall . . . that's a heck of a moment load on the unsupported bricks.

I love the O-T. I can't believe it took until Page 2 for some good humor.

Do yourself a huge favor and spend the money on quality masonry bits. There is a night and day different in performance.

I am understanding your concern with anchoring to the wall. If it were a static mount, I'd be ok with regular masonry anchors but as you noted it was a full motion, things can loosen up. Additionally, it isn't clear if the wall is framed in at the top. As someone mentioned, if you can get in the wall behind it, I would build up a wooden brace between the studs and anchor into that with lag bolts. Probably overkill but the expense is minor at this stage.

this

1/4" plate on the back side of the wall with a hole pattern to match the tv wall bracket. This will distribute the weight on the plate across the wall.

use an SDS masonry bit with a rotor-hammer drill to drill the holes through he wall.

If you wanted to get real fancy you could hang it from the joists...

One issue is loosening some mortar joints without noticing as you drill. That is why the plywood is so helpful. Once loose it is a real pain to repair.

I miss you in the GMT. PLEASE come back.

if you can get to the backside...just use some long bolts with nuts and washers (or threaded rod)then you know it will be secure.

Tapcon with recommended masonry bit and can use regular cordless drill. use phillips screwdriver as to not overtighten.

If not this then do what mr. harahhan said.

Double liar.

WHEN your TV falls, I hope it is 15 seconds before the biggest play of the season AND it lands on you.

Yeah I would try and build up the back of the studs to the backside of the brick and tie in there through the brick. That way the only load the wall sees is a vertical one (assuming you dont overtighten the bolts/screws), with the stud seeing the lateral withdrawl force.

Find out how much your TV weighs, then buy the TV thing that is rated for more than your TV can handle. It comes with screws.

Or use the bracket that came with your TV.

Then all you need is to buy a drill. $40.

Or get a cabinet.

It's hard to tell in the photo, but the studs you see are not actually up against the brick wall that I'll be mounting to


How close are they? Can you put another 2x4 in the space, even if it is sideways from the existing studs? Or maybe a 2x6 at the cross section, below your red oval in the pic. Then just tie a 2x4 into the new board and mount through to that.
