Need to know how to do a finish like this.....?

Just prime the MDF with 2 coats of tinted water-based Kilz-it. One quart should be enough. Use small sponge rollers and place in plastic bag between coats. Wait about 1-2 hours. When primer is dry apply enamel paint tinted to espresso color. Apply 2 coats using sponge roller and foam brush.
