Dulux Matt is a smooth and creamy emulsion paint for use on walls and ceilings and is ideal for a modern, flat finish. It takes 2-4 hours to dry and will cover up to 13 m² on average. At B&Q we want you to be satisfied with your colour selection. Not all monitors will display colours the same and paint tins may not show the same colour as your walls do in natural light. We therefore recommend you order a tester pot online or pop in store to pick one up so you are sure that this is the right colour for you.
