Using a wet-on-wet method must be done quickly when working with acrylic paint. Buy yourself some extra time to create stunning colour transitions, blend colours smoothly and allow yourself to work on the same area for longer using Amsterdam acrylic retarder. This retarder prolongs the drying time of your paint while preserving the colour intensity and opacity. Adding a maximum of 5% of this retarder to your paint will slow down the drying time, giving you more time to work with the paint, with little effect on the viscosity and opacity. Mix the acrylic retarder thoroughly with your paint using a painting knife.
