Painting a wall can be a tricky task, especially when covering a dark colour with a lighter one. In general, darker shades like blues are considered better at hiding the previous colour since they have more pigment and can provide better coverage. On the other hand, white paints are considered poor hiding paints because they lack the depth of colour, meaning they will not fully cover underlying colours. When painting a dark blue wall, it is recommended to use a good undercoat or primer before applying two coats of a good quality topcoat in a lighter shade. Some sources suggest that three coats may be necessary to ensure full coverage.

What You'll Learn
Using a primer can reduce the number of coats needed
Painting a lighter colour over a darker one can be challenging. Dark blue, in particular, is a colour that is hard to cover due to the pigment. When painting over dark blue, the number of coats needed will depend on the colour being applied. White paint, for example, will require more coats—at least two or three—than a darker colour, which may only need one or two coats.
To reduce the number of coats needed, using a primer is recommended. A primer will help to cover the dark blue colour, and ensure that fewer coats of paint are required. For example, when painting with white, using a primer means that only two coats of paint are needed, rather than three. A grey primer is a good choice when covering dark blue, as it will help to neutralise the colour. A drywall primer is also a good option.
When using a primer, it is important to allow enough time for it to dry before applying the paint. It is also a good idea to test the primer on a small area first, to ensure that it will provide the desired coverage. If you are using a roller to apply the paint, it is also recommended to use a roller for the test, as rollers lay on more paint than brushes.
In addition to using a primer, there are other steps that can be taken to reduce the number of coats needed. Firstly, it is important to use a good-quality paint, as this will provide better coverage and hiding power. Secondly, the surface should be prepared properly before painting. This includes washing the walls with a sugar soap solution, sanding, and filling any imperfections.

Dark blue is a difficult colour to cover
It is recommended to use a good undercoat or primer to cover dark blue walls before applying the desired topcoat colour. A cheap white matt emulsion works well as an undercoat on dark colours. A light grey emulsion can also be used as a base coat, followed by two topcoats of white paint. Sanding the walls between coats is also recommended for a smooth finish.
The type of paint used also affects the number of coats needed. For example, white paints are considered poor hiding paints and often require two or more coats to cover a dark colour. On the other hand, darker shades like black and grey are considered better at hiding previous colours due to their higher pigment content.
When covering dark blue walls with a light colour, it is important to achieve an even finish. Most experts recommend at least three coats of the finish coat to achieve the desired result. However, some people have reported success with two coats of a good-quality paint. It is essential to leave enough time between coats for the previous one to dry and to use good-quality tools to minimise brush marks and other imperfections.
In summary, dark blue is a challenging colour to cover, and the success of the coverage depends on the quality of the paint, the type of paint, and the number of coats applied. To ensure a successful outcome, it may be advisable to consult a professional painter with experience and references.

Light colours will likely require more coats
Painting a wall involves several considerations, including the paint quality, colour change complexity, and surface type. One crucial factor is the number of coats required, which can vary depending on the colour you are painting over and the colour you are using.
When transitioning from a dark colour to a lighter one, the process can be quite challenging. Dark shades like blues, blacks, and greys are considered better at hiding the previous colour due to their higher pigment content and better coverage. On the other hand, light colours, especially whites, tend to have poor hiding power, requiring two or more coats to completely cover a darker shade. This is because light colours, such as whites, have lower opacity due to their "clear" base, which contains less titanium dioxide—the ingredient that increases the "hiding" properties of paint.
To achieve the desired finish when painting with light colours over dark shades, most experts recommend using three coats of the finish coat. The first coat can be a primer, which is especially important when using light colours over dark finishes. A tinted primer can be helpful, as it can provide better coverage. After the primer, you can apply two coats of your chosen light-coloured paint.
It is worth noting that higher-quality paints with better binders and additives tend to provide better coverage, smoother finishes, and greater depth of colour. They may cost more upfront, but they can save you from needing multiple coats of paint.
Additionally, the tools you use can impact the final result. For hand applications, a foam brush can provide more coverage than a bristle brush, resulting in a more even coat with fewer brush marks.

High-quality paint may reduce the number of coats needed
Painting a dark blue surface can be challenging, especially if you plan to cover it with a light colour. The number of coats needed depends on various factors, including the quality of the paint, the type of surface, and the colour you're covering.
When it comes to choosing paint, consider its hiding power, which refers to how well it can conceal the colour underneath. Dark shades like blues tend to have better hiding power due to their higher pigment content. On the other hand, light colours, especially white, often require more coats to achieve full coverage.
To reduce the number of coats needed, consider using a primer or undercoat. A coat of primer can help you achieve the desired finish with fewer coats of paint. When covering dark blue, a light grey primer or undercoat can be a good choice, providing a smoother transition to the final colour. However, if you're using a high-quality paint, you may be able to get away with just two coats of paint without a primer, depending on the desired finish and the colour you're using.
While high-quality paint may reduce the number of coats needed, other factors, such as surface preparation and application technique, also play a role. Proper surface preparation, such as sanding and cleaning, ensures that the paint adheres well and reduces the likelihood of needing extra coats. Additionally, using quality tools and allowing sufficient drying time between coats can help achieve a consistent and even finish.

Sanding between coats can improve the finish
When painting over a dark blue wall, it is important to consider the number of coats required for effective coverage. While darker shades like blues tend to have better hiding power due to their deeper colour and higher pigment content, switching to a lighter colour can be challenging and may require multiple coats.
To achieve a smooth and flawless finish, sanding between coats of paint is essential. This process helps to eliminate any rough spots, imperfections, bumps, or drips that may be present on the painted surface. By using fine-grit sandpaper, such as 220-grit, and sanding in a circular or back-and-forth motion, you can gently scuff the surface to create an even and smooth canvas for the next layer of paint to adhere to.
It is crucial to remove any dust or debris after sanding to ensure a clean surface for the next coat. This can be done using a tack cloth, a damp cloth, or a vacuum with a brush attachment. Sanding between coats improves paint adhesion and enhances the durability and aesthetic appeal of the final result. It is important to note that the type of sandpaper and tools used can impact the quality of the finish, so selecting the right grit and tool is essential.
Additionally, the timing of sanding is crucial. It is recommended to wait for the coat of paint to completely dry before lightly sanding the entire surface. Premature sanding can interfere with the curing process, leading to a weaker and less resilient paint job. Always refer to the manufacturer's recommendations for drying and recoating times to achieve optimal results.
By following these steps and taking the time to sand between coats, you can significantly improve the finish when painting over dark blue or any other colour, ensuring a smooth, professional, and long-lasting result.
