– The means of getting a better surface.
3 important advantages by doing a Fladder® finish sanding:
- Up to 50% lacquer saving
- Sharp edges are rounded slightly.
- Stain is absorbed more uniformly.
Fladder® finish sanding solves the known problems in connection with lacquering:
Ordinary wood sanding with a wide belt sander cuts the wooden fibres on the surface leaving it woolly due to the pressure of the abrasive material towards the surface. When lacquering this surface tensions occur in the fibres that causes them to stand up and makes the surface feel rough.
It is quite normal to apply a thick base coat that fully covers these fibres. Afterwards it is necessary to sand most of the base coat off.
If the workpieces are profiled this sanding has to be done manually which means a laborintensive process, a slow production flow and a high lacquer consumption.
The solution is a Fladder® finish sanding after the wide belt sanding and immediately before the lacquering.
As it is a non-aggressive sanding only the fibres will be removed and edges rounded slightly. The workpiece dimensions are not changed.

Up to 50% lacquer saving
Because of less and a lot smaller fibres left after the FLADDER® finish sanding it is possible to use less lacquer to seale the surface. Sanding is minimized and the surface is more uniform. Below microscopic pictures show the difference of a wide belt sanded surface and a FLADDER® finish sanded surface:

Sharp edges are rounded lightly
The layer of lacquer on sharp edges is very thin, which makes the lacquer sanding difficult and with a risk of penetrating the lacquer. When doing a Fladder® Finish sanding these edges are rounded slightly, without damage to the workpiece definition. The lacquer is then enclosing the edge better reducing the risk of penetration when doing the lacquer sanding.
Below are pictures of a sharp edge, painted before and after a NFladder® finish sanding.

Stain is absorbed more uniformly
With a FLADDER® finish sanding the material is processed in such a way as to open the wood’s surface.
This makes the stain penetrate more evenly into the surface and improves the wood’s structure.
