IKEA Hammarp countertop crack, what to do?

Hello everyone,

about 1 month ago we received our new Ikea kitchen, I assembled it myself and oiled the countertop 3 times as prescribed, but despite all that my wife showed me this spot on the countertop today, it looks as if the countertop is cracked, see pictures



Is this a material defect or where does something like this come from, and what should I do now, it is of course the countertop where both the sink and the cooktop were cut out, so replacement is not so simple either.

A little further up there is a spot that is slightly raised as if something is stuck underneath.



How can I best repair the countertop, I was thinking of lightly sanding it with sandpaper and oiling it again thoroughly or what should I do?

Hello Loby,

out of curiosity: was it HAMMARP (solid wood) or Karlby after all (thick veneer on chipboard)?

Regards,

It is a Hammarp board but it cannot be a solid board because if you look at the picture, the underside does not look solid

You should have seen from the cutouts for the cooktop and sink whether it is solid wood or a veneered chipboard.

It is massive, but then the crack surprises me even more, because it is so strange how the wood has split, it didn’t split from top to bottom but rather across, but well, never mind, I have now sanded it down and will oil it again.
