Imagine being so tuned out of your surroundings that you just carry on walking idly by... staggering

Hello.

Does anyone have any advice on hardwood Vs softwood ply for a home wall. Ideally I would use 18mm birch ply, but this costs around €600 for the amount I need I my area. Alternatively I could use softwood ply which would cost around €380.

Any advice on longevity, sturdiness, voids, flex much appreciated.

Here are the exact boards I am considering. Sorry it is in German:

Birch: https://www.hornbach.at/shop/Multiplexplatte-Birke-18x1250x2500-mm/5084835/artikel.html

Maritime Pine: https://www.hornbach.at/shop/Sperrholz-Seekiefer-II-III-2500x1250x18-mm-Zuschnitt-online-reservierbar/5194467/artikel.html

Advice on other options also appreciated. Thanks!

My board is built from the exact softwood ply you're looking at, also bought from Hornbach. It's excellent and no flex with the 18mm. Passt scho'  :2thumbsup:

I used pine structural ply - had not much choice in lockdown. It's a bit shit for screwons. Needs painted, but flex is fine.

When I say " a bit shit" I've had a few screws rips threads, but most have been fine especially with longer screws.

I've had the same thing happen in 15mm hardwood ply. I'm attributing it to the screws being too short in length and too small in diameter. Go with 5mm diameter screws (or at least 4.5) and you'll be fine. I had to order 5mm full thread spax, because the hardware store only had partial thread ones in the lengths above 4cm.

The biggest thing that's going to influence 'flex' (deflection) in this instance is going to be the C/C of the supporting members. The difference in stiffness between 18mm thk. ply X or Y will be fairly minimal.

For screws I use Screwfix's Turbo gold without issue (posi). I don't see the need for ktx or torx for the home user (plus stabbing yourself with a ktx bit seems to do some serious damage in my experience).

Due to a fuck up, our first set on the wall, got fixed with Pozi’s instead of the (much more expensive) Torx I had neatly lined up, ready to go.

We never switched back and have never had an issue.

Used the Torx for wall expansion later. Using Torx for structural work and Pozi for setting, helps (helps, there are some idiots out there) to ensure structural screws don’t get taken out during setting.

Can confirm, using an impact driver, it’s entirely possible to set a 5 or even 6 mm screw spinning in hardwood ply; always assuming the head doesn’t come off first.

On that point: Reisser Cutters from Toolstation, are my choice. Shankless, or you’ll have trouble getting them out again.

I also have those as my pinning screws of choice although the lift off lid has left this idiot looking a bit foolish once or twice before!

Ah, yeah.

Try picking 500 up from the carpet on the mats.

Tool belt for me, these days.

Thanks for all the replies. Very useful.

One more thing. Anything I should consider regarding painting the boards? I read somewhere that you should paint both sides to prevent warping, but dont think I have ever seen this on any other painted walls. Advice on best type of paint also welcome!

Thanks

Do you want to paint or think you need to paint? Might not have to which will save you some faff!

Unless it's for weather proofing or something like that there's no point imo. I've never known a problem with warping on unpainted boards, I assume if you have a sensible number of supporting members that'll be more than enough.

My garage board is pretty dry but I'm still getting the odd mold spore developing on the surface of the plywood (and some of the wooden holds). I used Ronseal Exterior Crystal Clear (matte?) varnish but probably should've done several coats.

I only use screw ons (no t-nuts) and it's fine 👍
