British Paints Paint & Prime Ceiling Paint makes short work of ceilings, with an undercoat and topcoat in one. From a simple freshen-up to a bold colour change, your room will feel properly finished in just one coat over a previously painted surface — or two on bare plasterboard, or to cover joins and dark colours. Applied with a brush, roller or spray, Paint & Prime Ceiling will achieve a velvety, modern look with no separate primer required. The flat finish will absorb light and make imperfections such as uneven textures, cracks and joints less noticeable from down below. It also comes with a guarantee against mould growth for five years. Coverage: 10sqm per litre.
