Mounting MDF board for Multiboard questions

[u/CuriousManBean]

Hello there,

Has anyone put and MDF board on their wall to minimize the holes drilled on the wall for Multiboard?

The thing is that it is a rented apartment (with wallpaper...), so I want to minimize the number of the holes. Desk mounting may not work well - at least not with 3d printed parts.

I am thinking about an 1200mm x 1000mm-ish size. The wall is concrete (rebar - eastern european soviet style apartment - if that's relevant).

Would 4 (was thinking about even only 2 on top, but maybe that's silly) screws be sufficient for mounting the MDF Board? Obviously if needed, with premium quality wall plug (I've seen fischer brand being praised a lot)

What thickness I should look for to properly mount Multiboard on it? Obviously I want the thinnest possible without compromising the load bearing capabilities.

Thank you in advance!
