The finish must be applied above, below and on all edges of the panel. The same number of coats must be applied on each face (we recommend 3 coats, or even 4) to ensure good resistance over time and to avoid deformation due to moisture absorption. Before starting the finish, make sure the panel is level and sand with 120 grit, then 150 or 180 grit.
Ideally, carry out a smoothing (light sanding) between each coat, and follow the advice of the supplier of your finishing product.
