I prepared the foam surface by wiping it clean with isopropyl alcohol and lightly sanding the surface. This cleans off any mould release and provides a little grab for the paint. EPO doesn't really like to be painted. You can coat over with water based MINWax polycrylic wood finish or similar clear coat spray.
