Floor chipboard upside down?

[Matematikern]

Placing "This side up" down is at least less revealing than if one (the friend) makes a mistake with "This side down"

My "friend" placed the discs with "this side down" so that the text was facing up 😐.

My "friend" did the same thing 9 years ago and proudly posted a picture here, and received a remark on the same thing.

Keeping this thread alive which started 11 years ago.

Tonight I have painstakingly fitted a board in a small bathroom. 3 water pipes and two drains I have fitted by means of grooves and holes in the board. As if I weren't already fed up with this long-term project that never seems to end, I discover just as the board falls into place that the joint looks so strange and immediately understand what is wrong. Sure enough, no text with this side up on the board. Almost had a total meltdown. Mostly because I'm already so fed up with this toilet and have already done most of it twice.

A bit calming then to read this thread. On the part that got messed up, I’m going to have a 12 mm board on top to create a slope towards the shower, so then it can't matter at all. On that board, I'm planning to do the fine details around all the pipes.

Our nut of a carpenter was also not literate and placed the boards upside down, although in this context that was the minor problem,

Old thread but also discovered that this sida ner ended up on one of my adjusted golvspånskivor and discovered at the same second that tongue and groove are exactly the same on both sides, which makes the only difference between the sides the text...

Why does it say this sida ner on one side if the tongue and groove is reversible? Otherwise, see no difference between the sides.

Old thread but also discovered that this side down ended up on one of my fitted floor chipboards and realized at the same moment that tongue and groove are exactly the same on both sides, which means that the only thing that differentiates the sides is the text...

I believe it's important to lay it the correct way if you're going to glue a linoleum mat, etc. directly on it. Apparently, then the seams shouldn't show. Correct me if I'm wrong.

Post #7 in this thread has the answer.

I discovered a bit too late myself that it says "this side up" on the underside of the floorboard in the attic. I realized it after swearing a bit about not being able to get the tongue and groove really tight no matter how careful I was and how much I knocked the boards together.

Cut two small pieces and put them together in front of you on the table, for example, and you can usually see this small difference in how the tongue and groove are designed (tight on one side and a small gap on the other). When laying under "field-like" conditions in old houses, there tends to be a bit of a gap here and there due to all the irregularities, so it's not that obvious and it seems as if the tongue and groove are the same.

I had to call the first particle board factory I could find to check, and it was as I suspected: the tongue and groove is slightly asymmetrical, so when it's pressed together, it leaves a gap on the underside to make it easier to get a tight joint on the top side. So, I have the gap (about 0.5 mm) facing up, which would only matter if laying vinyl flooring, but we're putting something heavier on top, so it doesn't matter. Apparently, the strength is not affected at all by flipping it upside down, and that feels like the most important thing...

There was some concern that the upper floor would be full of carpenters laughing hysterically today when we came to continue. A bit of an embarrassing story here...

Thanks for the answers anyway, this forum is worth its weight in gold.

Thanks, laid the floor particle boards upside down and your response reassured me.

I would think that the falsning starts from the top side so if the sheets are just slightly different in thickness, it will be smooth on the top side and a gap on the bottom side, and it doesn't matter there.
