mount heavy TV on indoor wall of brick

[plan-g]

Hello
I have an indoor wall made of mexitegel that the previous homeowners constructed. I'm now planning to mount my fairly heavy 50" plasma TV on it.

However, I'm quite uncertain. Is it even possible? Can the wall crack/tip over? Is the material too porous? How do I drill? What type of drill bit and should I drill into the mortar or the stone? What plug should I use?

Or is it better to drill through the entire brick and try to hit a stud behind it?

Hilfe! :x

I would never in my life attach the TV to the mexitegel (maybe a good time to tear out that mess?)... Figure out what's behind it and depending on the material there, attach the TV to that in an appropriate way.

A TV is not particularly heavy, so it's always possible to find solutions, but attaching to mexitegel when you don't know if it's secure or not is not smart.

The walls otherwise are plasterboard with wooden studs behind. Thus, there is presumably the same thing behind the mexitegel. If I measure out where the wooden studs should be, then maybe I can screw all the way to them.

But how do you drill into the stone? Or the joint?

The mount for the TV is certainly made for a flat wall, I would consider screwing up a 15 mm plywood board with bolts for the TV mount. The board is screwed with long screws into the stud, easiest through the joint (you can just drill up the hole in the joint with a screwdriver and concrete drill (or a wood drill you don't mind using)).

Sounds like a good plan. Use 6mm wood screws to attach to the studs.

I would drill with a masonry drill bit but without the hammer function, and if that doesn't work, I would use a regular bit to drill into the brick, still without the hammer function. The brick is probably much softer than the grout.

I don't agree with that. But a good stone drill (with small carbide tips at the end) and a hammer drill (rarely a screwdriver) can be used to drill in both stone and joint. But a wood drill will not work unless the joint is in very poor condition.
What does the holder's wall plate look like? Should the TV be able to swing out from the wall or lie flat against the wall?

Mexitegel is very soft and prone to cracking. Therefore, it should not be used for impact.

Repetition is the mother of knowledge, my teacher always said.

I measured out the studs precisely and then drilled with a regular concrete drill (not a hammer drill) right through the joints and into the studs. Also used anchors. Worked perfectly and now it seems to be rock solid. The wall bracket fit pretty well without a plywood plate. Thanks for the tips!

Plug in wooden stud? That's worse than a good wood screw, why did you do that? Difficult to fix now too because the hole you made should be 8-10mm...

 

[plan-g]

The plug was in the pre-drilled hole in the stone and never reached the wooden stud. That way, I secured it in the stone in addition to the stud.

Hmm, as long as you felt it 'pulled' on the rule, it should work. Otherwise, is it just sitting in the plug?

 

[plan-g]

It felt like that anyway. the screws were really long too. It was clear that there was a stud behind with the drill as well. Well well, now it's where it is and no more load than the current one will ever be added.
