Hello,
The kitchen is starting to be finished, and one of the last parts is the windowsill, which in this case is a stone slab that has previously been in the same spot. The slab rests on 3 supports just like in all other windows in the house, which of course makes it extra important to get all the supports at the right height.
The problem, however, is that the slab is bent and it probably became so because the previous supports were not perfectly aligned. If you look at the other windowsills in the house, you can indeed see that almost all of them are visibly bent.
My hope was that Pattex Montager Glue No Nails would be able to straighten the slab, so I glued and braced it, and after 12 hours it was removed. Initially, it looked good, but after a while, one gave way, and this is what it looks like:

Here you can see the support where the glue has come loose, although the other 2 supports are holding the slab in place.

I can add that it required about 8 KG at each end to get the slab straight, so I assume it is around this force that the glue must be able to hold.
So the question now is how to fix the problem? Is there perhaps a different type of glue that should be used? Do I maybe need to put the stone slab under pressure for a week or two to get it straight? Or do I possibly need to buy a new slab?

Xtremfix has been mentioned as a very good mounting adhesive in another thread, if it holds up to half of what they show it should be more than enough for your board.

Why not accept that the disc is slightly bent?
Since you noticed it on the other discs only when you reviewed them, it's not something visible once you add some flowers or other decorations.

I've actually noticed it before but concluded that it was part of the overall quality of the build. Now that I'm redoing it, I want to make it as good as it can be.BirgitS said:
The alternative is otherwise to order a new board that is actually straight (and in better condition).
Image search works quite well.
As long as you don't drill into them, there's nothing to worry about, i.e., continue trying with glue.
If you replace the boards, they should be disposed of in a special container at the dump. It costs nothing extra for private individuals.

Do you think Bostik MAX BOND works as well as XtremFix?

Not so easy to get hold of Casco where I live.

I've come to the conclusion that it isn't stone after all, but I don't know what material it is. The sheet is glued now, and according to the instructions, it takes 4-7 days for the glue to cure, so the clamps should be able to be removed by Sunday.
