This becomes clear when you start refurbishing the door. With the Festool ETS EC 150 eccentric sander, light sanding of existing coats of paint is a smooth and reliable process. With the right speed, loose pieces are removed without too much pressure and intact surfaces are roughened.
In the first step, the surface of the door is therefore lightly sanded with the ETS EC 125 or 150 eccentric sander. We recommend that you use abrasives with a grit from P150/P180 for water-based paint and a grit from P150 for alkyd resin paint.
