This ultra matt emulsion will give a brighter and more spacious feel to any room and helps your walls withstand the rough and tumble of family life. The patented LumiTec formulation works with light-reflective particles to reflect up to twice as much light back into your room, and the Diamond formulation makes it 20x tougher, when compared to regular emulsion paints. 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.
