Need some load advice.
 

Want to hang a 32 in tv outside.

Weighs maybe 20 lbs.

House is clad/sided in brick.

Have a proper articulated mount for it.

So the question is, do I need to to make sure I get into studs behind the brick cladding or will lag bolts in the brick be enough to support it?

I'm under the impression that the brick holds up better under compression and not necessarily shear.

Bricks look like this.

TV going here.

Watcha guys think?

Into the brick should be fine... sound the brick where you want to place the mount...if it sounds hollow move the location of the mount ... or you can get toggle bolts and go through the sheathing...

Otherwise anchor into the brick

Finding a stud may be a bit of a challenge..

Brick is fine.

Our 42 is just mounted into the bricks....

I'd mount it in the mortar joint.

why not screw a 2x4 up top to the existing wood
and let the tv hang down from that

Brick is fine. We have a 40" LCD mounted to brick inside and a 40" LED mounted outside.
If your weight is only 20 lbs just use 4 lag shields into the brick, throw in 6 if you are worried. It doesn't look like the red brick your mounting on is hollow, usually red brick is solid.
20lbs is not that heavy. You'll be ok.

One of the products we installed at the company I used to own was exterior shutters. We found mounting into the brick was better than mortar for long term holding. Sometimes the mortar would crumble a bit during drilling. Definitely easier to drill though.

We had good luck using Redhead brand masonary screws.

Not so sure about that. Would it not crumble easier than the brick.

The wood up top is just thin decorative ply, not sure what's under it. I'm sure there are stringers but I've got a couple of spare wall mounts so don't want to have to buy another.

The bricks are hollow, see first pic.

Thanks all.

Mortar is more likely to blow out.... We mount things to brick walls all the time. Prefer to drill the brick if at all possible, the anchors will hold much better.

I'm not a professional builder, but I would be slightly concerned about the torque stress of a 20 lb. weight held out at a distance along with the weight of the mount. I'm sure the prior advice to anchor into the brick is OK. Those look more akin to concrete block with a faux brick front. If it were me, I'd try to anchor at least the top anchors in one of the solid sections that go from front to back. It might take a little dective work and measuring to find those parts of the brick facing.

I thought you were mounting to the wall, those are red bricks.
The stack of brick at the bottom are brown. What are those for?

Mount the TV directly to the red brick. You will be fine.
Our TV is mounted above the fireplace directly to the chimney brick, 'red'.

Get a hammer drill, the proper size masonry bit and your good. Try to drill into the brick, not the mortar. The brick is easier and holds just fine.
If your tv is only 40 lbs and you are using 4 lags that is only 10lbs a piece.

Marv, We have a 42" TV mounted to a very similar brick wall, its been up for about 4 years now... No issues...

I was here every day while the house was being built.

The bricks in the first pic are extras.

Trust me, the bricks are not solid.

I'm guessing those are the left over bricks. :) Not uncommon to keep some around in case something happens down the road.

Sid, that's good to hear. I was just saying from my point of view, I'd attach it in a way to avoid problems down the line and the way I mentioned is something I'd consider if I were doing it - & I'd use Redheads. I think I'm not up on the latest TV's although we have two flat screens (42 in.), but the older is really heavy & the newer one is quite a bit lighter although not light. They are certainly not like the 32 in. tube TV I bought in the late '80's & replaced around '04.

Hilti makes some special anchors for attaching things to brick or block. I would consider those.

If the TV is going into the corner of the two walls, consider a simple, custom mount that spans between the two walls.

If your TV weighs 20lbs and you use four mounting bolts that is 5lbs per attachment point. If you can't hang that weight you have more issues that just a TV to worry about.

I forgot to add: Use lead shields in the brick.

If the TV is cantilevered out from the wall, that's not how you do the math...

JR

And this is why you don't use the joints for attachment points. No need to put expansion forces there even though you would have to move several courses of brick to lift the joint.

How to use a lag shield (and why do they call them "shields?"):
Drill hole the correct size.
Drill to the correct depth. Tape on the bit or a depth gauge on the drill motor.
Clean out the hole thoroughly with air blown through a flexible tube.
Put a little glue on the shield, can be white glue, poly like Gorilla, or some epoxy.
Insert and tighten lag lightly. Use washers under the lags and under the bracket to level out. At least one washer under the bracket will help the shield from pulling out.
Re-tighten only enough to snug up well the next day.

Yeah that was my concern, that the TV hanging off an arm might pull the lag bolts.

That was my next thought.

But I think lags will be easier to undo?

How do you remove epoxy from the exterior?

The Hilti system uses mesh sleeves that are inserted into holes drilled in the brick, then filled with epoxy. You insert an appropriate fastener into the sleeve after the epoxy goes in. There is no epoxy on the face of the brick.

Removel is not as easy as just unscrewing a lag bolt. However you do it, you're going to have holes to fill if you remove the bracket down the road. I'd just take out those bricks and install new ones at that point. It's not that big a deal to do.

If you want to minimize the loads and the size of the anchors needed, throw away the bracket you bought and make your own mount that spans between the two walls and hang the TV from that. If you do it right, the loads can be essentially all in shear, which makes them very small. In that case, relatively small anchors will work.

Brick should be fine. My 40" is mounted to brick but it is just a flat mount. It surprised me how strong the lag bolts felt once in there.

True, but my basic point of not much weight is still in effect. I mean we aren't hanging a 1972 Curtis Mathis full console TV here.:D
