ᐅ Is a TV wall mount stable on a brick wall?

Good afternoon dear forum members,

I want to install anchors in a brick wall to mount a TV wall bracket with a maximum load of 40 kg (88 lbs). Unfortunately, I am not sure what type of brick this is or if anchors would be strong enough.

Photos are attached. Maybe someone knows better what to do 🙂

Thank you very much in advance

Anyway, you don’t really need to worry. Even 12.5mm (0.5 inch) drywall would hold 50 kg (110 lbs) with appropriate anchors and four screws.

Are you sure about that? I admit, I’ve never tested it myself. But during my first training in a hardware store, they always advised against it.

Let's put it this way: I don’t have personal experience with 50kg (110 lbs), but according to technical specifications, it is possible. As I said, with the right anchors and proper installation. The anchors must not spin.

From my own experience, I know that 30kg (66 lbs) works, but strictly speaking, that usually wouldn’t be enough for a 65-inch TV along with the wall mount.

However, I still maintain that the wall shown in the photo will definitely hold.

Ah sorry, I double-checked: it is 40 kg per m² (8.2 psf) for single sheathing and 50 kg per m² (10.2 psf) for double sheathing. Per hollow wall anchor, it is 25 kg (55 lbs) for single and 30 kg (66 lbs) for double.

From my perspective, there are two important criteria:

1. Does the wall hold?
2. Does the anchor hold?

1.
With a masonry wall, I generally wouldn’t worry, no matter what it is made of. If the anchor is properly installed, the wall will hold.

2.
Anchors perform very differently depending on the type of wall and how they work.
In my experience, the safest method is to drill a hole and glue threaded rods in place.
The adhesive used for this is often quite expensive.
My tests so far have shown that even cheaper adhesives hold well enough.

For example, from Förch. I used it myself for the ring beam when adjusting the masonry afterwards.
It creates an extremely strong steel-to-wall connection.

But for a TV? You can probably just stick the bracket on with good mounting adhesive :P
