How to fix 90x45 stud to brick wall?

[Six7]

Hello,

Need some advice with the fixing of the stud to the brick wall.

Brief: Living room, two brick piers with a brick wall and shelf on top with a void, wanting to panel it up, 3m ceiling height and panels from floor to about 2.6m high, decorative panel on top.

The vertical stud will not have a top plate due to the mount for the TV will be near the top (recommended fixing to vertical and not horizontal). TV is a whopper of 85" and weighing about 58kg + the heavy-duty mount.

The verticals will need to be fixed through the 45mm edge of the stud, most of the 8mm fixings aren't long enough so it will need to

be recessed unless I go up to 10 or 12mm screws.

Heavy-duty - Masonry screws for the two verticals and the rest plug and screw?

Hello @Six7 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing you question about installing a stud wall.

I suggest using a double vertical stud assembly due to the weight you'll be putting on the stud wall. I recommend using at least 12g screws for a more secure fitting. I propose looking at chemical anchors such as Ramset 300ml Chemset UltraFix Plus in combination with Ramset Multifit Sieve - 4 Pack along with Ramset Multifit Sieve - 4 Pack. I suggest engaging the services of a builder to double check that the stud wall construction can hold the weight of the TV. 

To put it in perspective imagine hanging a Mondella WELS 4 Star 4.6L/Full Concerto Back To Wall Rimless Toilet Suite on conservatively 6 to eight mounting bolts on a timber stud frame. 

Let me call on our experienced members @Nailbag, @Dave-1 and @Noyade for their recommendations.

If you need further assistance, please let us know.

Good morning @Six7 

I would attach your vertical timbers for your frame with masonary screws Ramset 10 x 75mm Galvanised AnkaScrew Masonry Anchor

Making sure that you are at least 80mm from the corner edge with the hole, thats just a guesstimate for maximising styrength.  (the screws do come in larger packs as well) You could also add a washer but its not really needed with the head of the bolt.  I attached my frames for my false  walls to my brickwork like this.

Is there a reason you are doing the paneling in two sections instead of one? It would distribute the weight better if you had the vertical section cover both sections of the paneling from your sketch. You could still frame the whole lot up before installing the frame in one go. 

Note, measure the distances of the pillars (between them) at the top and at the bottom Sometimes things are not what we expect and even 5mm difference can be a pain.

Hi @Six7 

You could use 100mm x 10mm Dyna-bolts or Orange spaghetti and 100mm batten/bugle screws, which is usually how I would fix the battens to a brick face. Ideally drilled in to the brick not mortar and 4 fixing points per side. This will be ample fixing.

Thanks for that @Dave-1,

Is there a reason you are doing the paneling in two sections instead of one?

The reason they are in two frames is due to the existing shelf which I was trying to avoid removing, just in case the panels are removed in the future, I know if I remove it, I could have a full length vertical and wouldn't have any issues fixing the TV bracket.

Note, measure the distances of the pillars (between them) at the top and at the bottom, sometimes things are not what we expect and even 5mm difference can be a pain.

I was kind heading towards the Ramset-10-x-75mm-galvanised-ankascrew-masonry-anchor as long as there is enough purchase in the brick wall and I don't hit any mortar.

Thanks, heaps for the tip...have a top day mate!

Hi @Nailbag,

Thanks for your suggestions, I don't have a good experience with Dyna-bolts and might stay away from them, I might go with the ankascrew-masonry-anchor for the heavy duty verticals that @Dave-1 suggested and use the orange spaghetti with batten screws for the rest.

What happens if I encounter a mortar hit?

I will measure for brick course heights and adjust my fixing where required.

Thanks for your tips mate, have a good one.

Hello @Six7 

My best advice would be to double check your mounting points on the brick face to make sure you miss the mortar joints. A good visual confirmation will be more than enough to guarantee that you drill into the brick face and not the soft mortar.

Hi @EricL 

Thanks for the tip, I will need to measure as the brick wall is plastered.

Cheers mate 👍 have a good one!

Hi @Six7 

If you've had bad experiences with Dyna-bolts (we all have) it's typically because the hole is too large, shallow (hit a hollow) or soft (soft mortar). Anchor screws are great but even more unforgiving on all those points. 

If you hit mortar then just fill it with spaghetti. Doesn't matter if its not central, the screw will still bind as it compresses the stagette outwards.

Hi @Nailbag et al,

I'm about to start the project and need one more thing.

Is the orange spaghetti two pieces joined together as Beowulf Builders did in his video?

Drill a 10mm hole?

Can you please confirm the hole size.

Thanks heaps...I hope to hear from you very soon.
