Basically, the following applies to wooden floorboards, terrace boards, and all wood-based materials:
Splintering, which results in a risk of injury, is not allowed on a board under any circumstances!
Depending on the sorting characteristic (which is listed on the product data sheet or should be indicated on the outer packaging),
the limit of goodwill has already been exceeded with cracks sealed with a black filler.
There are different requirements for wood grading depending on what the customer has agreed upon with the dealer (or what was advertised on the parquet).
For the grade with the lowest requirements the following applies:
[*]Knots without size limits
[*]Putty-filled knots and putty-filled cracks
[*]Sapwood as well as natural grain
[*]Coarse color and structural differences
However, the color deviation of the filler must not differ as significantly as shown in the picture/photo, and the size or length of the cracks would also be a reason to question the original grading.
As soon as the visual appearance is significantly impaired by filled cracks, knots, or sapwood, the dealer can no longer invoke the aspect of lower purchase costs. Unless the builder (provably) was informed of the various aspects prior to purchase.
