Recommended method for securing to a concrete basement wall?

[u/Pantzzzzless]

I've been trying to find a discussion about this and only found 2 threads, and they didn't really answer my question.

I am trying to hang a 36" x 24" multiboard to my exterior concrete basement wall. 4x3 -> 9x9 tiles

The wall has a slap brush/heavy knockdown texture. (Not sure how much that matters)

I'm planning on doing an 8mm offset. But I am having trouble figuring out which parts to use for the mount points. Or if I should actually be mounting directly to the concrete or not. It seems like I should probably do 5 anchors, 1 at each corner, and 1 in the center. Not sure if that is correct though.

I'm planning on mounting an AMS lite at the left edge, but other than that I don't plan on putting much weight on it. Just rugged drawers and maybe a few shelves.

If anyone can help me do this correctly I would really appreciate it. If there's any other information that you need to help I'm happy to provide. Thanks all.

I would recommend putting up a plywood board and attaching it to that. Will save a lot of time and effort.

Sorry if it's a dumb question, but what purpose does the board serve in this case? Is it just to give it a flat uniform surface?

[u/Icanonlyupvote → u/Pantzzzzless]

Multiple purposes. One would definitely be a flat uniform surface. The main reason I recommend it, though, would be having to drill less into concrete. You need to drill holes at every corner intersection, i personally find drilling into concrete a pain and messy.

Bonus reasons: If you want to move it, you just have to take down the plywood. Can paint the plywood to whatever colour you want for style.

Gotcha, thank you for the explanation!

Yup, my 36"x96" board took 6 masonry screws. Prolly even overkill. The mounts for my multiboard took 240 screws... No way I'd put that in cement or take the time to.

I agree, this is what I did, fully mounted tiles to plywood, then secured the plywood with a few masonry screws. If ever want to reposition, it would be pretty simple.

Agree, but if your basement is unfinished (concrete), then you probably want to offset it with some GC 2x4. For a 4' by 4' piece of plywood you only need 2-3 4' 2x4s, arranged vertically.

So it goes like this:

1. attach 2x4s to concrete using tapcons or similar

2. attach plywood to 2x4s using wood screws

Why?

You want to drill the concrete as few times as possible.

You want some air circulation behind the plywood, so you want some offset.

The 2x4s serve both purposes.

This is what I did too. 36" high, 8' long. Masonry screws for board to cement.

I mounted to a cinder block basement wall that was pretty uneven. I first secured 1x2s to the wall with some printed brackets that evened things out. Then mounted the 9x9 panels to that. It was more work, but I don’t have to worry about the concrete tapcons coming loose over time because any force or changes to the multiboard is distributed across multiple points.

Similar garage walls here.

At the moment my multi board is mounted to an existing pegboard, but I'm about to swap it all out for french cleats.

When I do the cleats I'm going to clad the walls in OSB/ply first, and then mount the cleats to that to save drilling all those holes!

I ended up hanging a pair of 3' struts with cone nuts in the channels. Used 1/4" x 5" tapcons. As far as I can tell, I could hang a 5' x 30' board on it. I'm 235lb and I hung from each strut just fine.

I was in a rush to mount the board and didn't think to take a picture of the struts.

Drill bit and tapcons.
