A building panel comprising:
- a first surface layer comprising a first wood veneer,
- a wood fibre based core, and
- a first sub-layer arranged between the first surface layer and the wood fibre based core, wherein the first sub-layer comprises a filler and a binder applied on the core in liquid form,

1 more element
A method to produce a building panel, the method comprising:
- applying a first sub-layer comprising a filler and a binder on a first side of a wood fibre based core;
- applying a first wood veneer on the first sub-layer to form a first surface layer,
- applying heat and pressure to bond the first wood veneer, the first sub-layer and the wood fibre based core together, thereby material from the first sub-layer is pressed into holes and/or cracks of the first wood veneer,
- wherein the first surface layer has surface portion comprising material from the first sub-layer extending into the first wood veneer.
