Johnstones Covaplus Vinyl Matt in Red is a premium water-based emulsion designed for both DIY enthusiasts and professional decorators seeking a sophisticated, low-sheen finish on interior walls and ceilings. Its rich carmine undertone provides a striking mid-bright appearance, while the formula offers excellent durability and washability; however, users should be aware that the high-pigment red may require multiple coats over dark or uneven base colors to achieve full opacity.

While it is durable, this is an interior wall and ceiling paint. For high-humidity bathrooms, a dedicated moisture-resistant bathroom paint is recommended.
Two full coats are usually sufficient for standard surfaces, though more may be needed for bold color changes.
This formula is specifically optimized for walls and ceilings. For wood trim, a dedicated trim or eggshell paint provides better durability.
It is generally touch-dry within 1 to 2 hours depending on room temperature and humidity.
As a modern water-based emulsion, it has a low VOC content compared to traditional solvent-based paints.
Ensure you are using a quality synthetic roller and avoid overworking the paint as it begins to dry.
Check the surface preparation; apply an additional coat or use a primer/sealer if the substrate is highly porous.
Avoid painting in direct sunlight or high-heat conditions, as this causes the water-based binder to evaporate prematurely.
Before starting, ensure your walls are clean, dry, and free from loose flaking paint or dust. For porous surfaces like new plaster, apply a mist coat—a mixture of the paint with a small amount of water—to seal the surface before applying the full-strength coats. Use high-quality synthetic brushes and medium-pile rollers for best results. Maintain the finish by avoiding harsh chemical cleaners; a soft, damp cloth is generally sufficient for removing light dust or fingerprints. When storing, ensure the lid is sealed tightly and kept in a cool, frost-free environment to maintain the paint's integrity for future touch-ups.
