Illustration 1: 1 CAUSES The substrate has been sanded with a too coarse-grained abrasive and therefore the product applied subsequently penetrates inside the grooves. The drying times prescribed for primers / undercoats were not respected. The sanding lines become visible due to absorption after drying. Too thin layers of primer / undercoat / enamel that do not fill the sanding lines in the layer on which they are applied. Unsuitable sanding or sanding technique. PREVENTION Use sandpaper with the recommended grain size (for putty, P80 / 150; for primer and filler base, P 240 - see the "Technical data sheets"). Use the sanding check light. Follow the drying instructions. Observe the prescribed layer thicknesses. Place the sander on the support and switch it on only afterwards. For dry sanding of primers and undercoats, use an eccentric sander with a maximum orbit of 5 mm. REPAIR Sand and repaint with suitable primers and enamels.
