BauBuche Panel Technical Info

BauBuche Panel behaves in a similar way to solid wood boards. After transport it is necessary to ensure that the material can adjust slowly to the workshop climate. This means that, after cutting to size, stickers (spacing sticks) should be placed between the individual boards.

Longitudinal edges, particularly if the length is greater than 2.0 m, are often not exactly parallel with the laminations, so even after careful cutting (or parallel cutting) the glued joints become visible. If necessary, a solid wooden edge (e.g. made of Pollmeier beech sawn timber) can be glued on. If this is done with an automatic edging machine, it must be ensured that the glued surfaces of the edges have not been planed, but have a sanding pattern with a grit size of 40 or 60. The edges should be treated with an adhesive primer (e.g. Dorus ND 183 / 1). Even better results will be achieved through the use of a PVAC glue (D3 or D4).

All drilling, cutting and edge finishing should be completed before the surface treatment.
– Sand on a cylinder sanding machine (grit size 80 / 100) for the first pass. _ Depending on the cutting quality of the abrasive, set the machine
to “Calibrate”.
– Sand with 120 / 150 grit in the sanding machine, using a sprung table
or compressed air sanding shoe, depending on the type of machine. _ Then thoroughly blow-clean the surfaces with compressed air to
remove dust and loose fragments.
– Level out any voids that have occured with filler (solvent mixed
with sanding dust, e.g. Pallmann Fugenkitt-Lösung (joint filler
solution) No. 39 948).
– Using precisely working sanding machines, the surface can be machine-sanded (grit size 150 / 180) after filling

– Priming: Applied quantity approx. 200 g/m², sprayed crosswise and lengthwise. The subsequent intermediate sanding is ideally done after drying overnight in a temperature-controlled drying room.
– Sand in sanding machine using varnish sandpaper, grit size 220,
or with orbital sanders.
– 2nd varnish coat at least 170 – 190 g/m².
– The edges have to be varnished several times in order to avoid
varnish runs.
– After an adequate drying time of at least 1.5 to 2 days at a constant temperature of between 18°C and 20°C, the boards can be stacked with wide intermediate supports. If these supports are too narrow or too hard, they will cause pressure points, due to the weight of the boards.

All drilling, cutting and edge finishing should be completed before the surface treatment.

integrated edge grinder
