Attach post in brick.

[Lexington]

I will attach a post (95x95) to a brick wall (common brown brick), quite close to a corner, with four screws (the post will also be fastened to a ground anchor and will be one of three posts for a small fence).

Should I drill and plug into the brick or into the mortar joint, what's recommended?

I don't know if the brick is solid or hollow.

Even I am curious, though with mounting in mexitegel

Depends on the quality and age of the joint. If the house is older than 40 years, I would always use stone, and probably on newer houses as well.

The house is from '64, so it's set in stone

Any tips on how to measure where the plugs should go? Should I drive the screw through the post and mark where it lands on the brick, then drill? Or is there a more convenient way?
One more thing, the screw will go about 6 cm into the brick, how long does the plug need to be?

 

[mexitegel]

Facade plug is quite suitable

 

[Lexington]

Fasadplugg is appropriate, right

Yes, absolutely or some form of concrete plug anyway.
But should I use a 5, 6, or 7 cm plug? So shorter, the same length, or longer than the screw going into the wall?

Edit:
It just occurred to me that maybe you weren't responding to my post?

 

[mexitegel]

Yes, on your post

The facade plug is also in the post you screw on. The brick is about 10 cm thick so a facade plug 10x180 should be suitable?

 

[Lexington]

Yes, in your post

The facade plug is also placed in the pole you fasten. The brick is about 10 cm thick so a facade plug 10x180 should fit well?

I see
Yes, that sounds wise then!
But I'll save my 160 screws for something else and go with the facade plug!

Thanks!

6 cm is on the low side, but should work for a small plank. The screw should go through the entire plug. To get the holes/plugs in the right place, you can do as follows: 1) Pre-drill the top hole through the post so that your screw runs freely. 2) Hold the post in place and with a long, narrow drill (or nail) mark where on the brick you should drill the top hole. 3) Drill into the brick, insert the plug, and attach the post. 4) Measure out where you want the other holes so that they hit stone, and pre-drill these holes in the post. 5) Level the post and mark in the brick. 6) Take down the post and drill the other holes, plug them, and attach the post. You may need washers for the screw head when you pre-drill. Often, coach screws or facade plugs are used (then the plug lies through the post).

You may need washers for the screw head when pre-drilling. Often a French screw, or facade plug is used (in this case, the plug goes through the post).

Detailed and good! After a tip from "mexitegel," I'll probably go with a facade plug, so no need to take down the post, just get a long concrete drill, drill and screw it in.

New question :x
Since the post is going to be close to a corner, I have two options: drill, plug, and screw into the short side of the brick or into the long side, which is better? Or does it not matter?
Is there no risk of cracking the brick if you go into the short side?

 

[Lexington]

Now I've been to two well-stocked hardware stores here in town, both had 140 long facade plugs individually, one had 160 but in a box of 50, I need 3!

Where can I find 180 long individually??

 

[Lexington]

Found loose 160 facade plugs at Byggmax, maybe not the best quality but it should suffice for my purpose. I'll countersink them 20 mm into the post and it should be fine.

Does anyone know which is better regarding fastening? Drilling into the long side or short side of the brick?

Maybe it doesn't matter, but I would choose to place the post on the side of the stone that provides the most material on both sides of the drill hole.

Good luck!

The post ends up right at a corner, and the fence becomes an extension of the facade, but then I'll drill and attach to the long side of the brick!
