We suggest 240-320 grit abrasives. For best results, use stearate abrasives. They provide higher efficiency than normal abrasives. Ensure the surface is completely clean of debris before coating. See our pages for suitable abrasives for water-based products.
With good drying conditions and with good air circulation 20°C with 65% humidity), build can be achieved with just 2 to 3 coats. Each coat of 150 - 250 G/M² with an interval of 60 mins. Under these circumstances it can be sanded after 8 hours. Lower temperatures and higher relative humidity can lead to a longe rdrying time. It is possible to speed up drying using heated ovens. Can be catalysed 2% of YC-M402 for increased thermo-plasticity.
YL-M641 can be overcoated with any of the pigmented Renner Waterborne Topcoats.
It is important to understand when switching over from a solvent-based coating system to water-based, to check whether your equipment and apparatus are appropriate or whether you may require more suitable solutions.
