Priming fresh plaster is essential for a smooth finish. Start by letting the plaster dry completely, which could take up to a week. Apply a mist coat, mixing water with emulsion paint (roughly a 70/30 ratio), to seal the plaster. Apply evenly with a roller and allow it to dry. Then, proceed with your chosen topcoat paint, ensuring full coverage and an even, durable finish.
