DD lacquer

DD varnish is a topcoat applied to boats. It can also be applied as an anti-slip paint, by adding 5-10% anti-slip powder to the paint before use. A boat is finished above the waterline with three coats of DD varnish. Today these are sold under the trade name URKI VOC or PUR 2K lacquer. for info, see; https://www.v-sure.eu/nl/producten/polyurethaan/polyurethaan-vernis/
