The Ripple pad has a very dense charcoal coloured tri-fibre foam backing that is cut to the shape of small corrugations - it looks a little like a small profile of mini orb ... then it’s covered with acrylic mohair ‘flock’ bristles just like our other paint pads. Only the bristles on the tops of the corrugations make contact with the surface, less surface tension means less drag - which means much easier application of the thicker paints that are harder to manage like some of the modern undercoats, surface preparations and thick heavy ceiling paints.
