When it comes to painting, be it a wall or a piece of art, the paint you use can make a big difference. Cheap paints are usually thinner and contain less pigment and fewer binders, which are crucial for an even application of colour. This means that you may need 2-4 coats of cheap paint to get an even finish, whereas with more expensive paints, you may only need 1-2 coats. The cost of pigments themselves also varies depending on their source, demand, and rarity, which affects the overall price of the paint. This means that cheaper paints may use less pigment or substitute it with fillers to reduce costs. So, while paint with less pigment may be cheaper, it could end up costing more in the long run due to the need for multiple coats.

What You'll Learn

Cheap paint requires more coats
When it comes to painting, it's important to consider the quality of the paint you're using. Cheap paint is typically thinner due to a lower pigment content, which means it provides less coverage and may require multiple coats to achieve the desired result. This can be especially challenging when painting with dark colours or trying to cover a bright or dark colour underneath.
Pigments are granular solids incorporated into paint to give it colour. They are one of the key ingredients that affect the quality of the paint. Cheap paint often contains less pigment, which can result in a less vibrant colour and inadequate coverage. To compensate for the lack of pigment, you may need to apply several coats of cheap paint, which can be time-consuming and costly in the long run.
On the other hand, expensive paints usually contain more pigment and binders, providing better coverage with fewer coats required. A higher ratio of fine particle pigments in higher-quality paint means that one coat may be sufficient for even and consistent results. This not only saves time but also reduces labour costs, as you won't need to spend as much time applying multiple coats.
Additionally, high-quality paint is more likely to be fade-resistant, ensuring that the colour lasts longer even in rooms with ample sunlight. It's also worth noting that some expensive paints come with warranties, guaranteeing their quality and longevity. While the initial cost per can may be higher for expensive paint, the overall cost of painting a room may be the same or even less compared to using cheap paint.
When deciding between cheap and expensive paint, consider the number of coats needed, the time and labour involved, and the long-term durability of the paint. While cheap paint may seem like a more affordable option upfront, the need for multiple coats can increase the overall cost and the time required to complete your painting project. Therefore, investing in good-quality paint with higher pigment content can save you time, money, and effort in the long run.

More coats increase labour costs
When it comes to painting, whether it's a DIY project or a professional job, the choice between cheap and expensive paint is a significant one. While cheap paint may seem appealing from a cost-saving perspective, it often requires more coats to achieve the desired colour and coverage, leading to increased labour costs.
Cheap paint tends to be thinner and contains less pigment and binder, which are crucial for achieving an even and consistent colour. As a result, multiple coats are usually necessary, especially when covering a dark or bright colour. This not only increases the amount of paint required but also extends the project timeline. In contrast, high-quality paint, despite being more expensive per can, provides better coverage and often requires only one or two coats.
For example, let's consider Behr Interior Paint – Premium Plus, priced at $31.98 per gallon. One gallon may be sufficient to paint an entire room. On the other hand, a cheaper option like America's Finest, priced at $11 per can, may require three to four cans for the same room. The total cost for America's Finest would be $33 to $44, which is already more expensive than the premium option, and that's without considering the additional labour costs.
The extra coats needed with cheap paint not only increase the overall time spent painting but also delay the project's completion. Each coat of paint typically takes 1 to 2 hours to apply, and it takes another 4 to 24 hours for it to dry before the next coat can be applied. With cheap paint requiring up to four or more coats, a project that could be completed in a weekend with good-quality paint might end up taking a whole week.
Additionally, the use of multiple coats can lead to an uneven finish, with potential blemishes that need to be addressed. This further adds to the labour time and costs, as proper preparation and priming become even more critical to achieving a satisfactory result.
In conclusion, while the upfront cost of cheap paint may seem appealing, the need for more coats significantly increases labour costs. The additional time, effort, and materials required can quickly outweigh any initial savings. Therefore, investing in good-quality paint is often the more cost-effective and time-efficient choice.

Expensive paint contains more pigment
When it comes to paint, there is a noticeable difference between cheap and expensive options. One of the key differences is the amount of pigment in the paint. Expensive paints contain more pigment and binders, which provide better coverage, meaning you need fewer coats. This is particularly important when painting with dark colours, as these paints have a transparent base, so cheaper, thinner paints will struggle to provide an even layer of colour.
Cheaper paints will often use less expensive alternatives to pigments or will reduce the ratio of pigment in the paint to cut costs. For example, cadmium yellow hues are cheaper than genuine cadmium pigments, and earth colours are also a cheaper alternative.
The higher pigment content in more expensive paints means that, despite the higher cost per can, the overall cost of painting a room will be the same or less than using cheaper paint. This is because one can of expensive paint often provides the same coverage as two or three cans of cheap paint.
In addition to better coverage, high-quality paints are often fade-resistant, meaning the colour will last longer. This is particularly beneficial in rooms that receive lots of direct sunlight.
Therefore, while expensive paints may contain more pigment, this does not necessarily make them more costly in the long run.

Cheap paint contains blanc fixe
Cheap paint is often thinner and contains less pigment and binder—the most important ingredients in interior paint for an even application of colour. In contrast, expensive paints are of higher quality, containing more pigment and binders, which provide more coverage.
Cheap paint may not be suitable for painting the inside or outside of a house, but it can be used for small craft projects. One of the ways paint manufacturers reduce the cost of paint is by using fillers, which are granular solids incorporated to impart toughness, texture, give the paint special properties, or to reduce the cost of the paint. Fillers are usually cheap and inert materials, such as diatomaceous earth, talc, lime, barytes (also known as blanc fixe), clay, etc.
Blanc fixe is a chemically precipitated barium sulfate used as a filler in paints, coatings, plastics, and as a functional additive in batteries. It is nearly insoluble in water, as well as in organic solvents, acids, and alkalis. It has good dispersion properties, excellent gloss, and low binder demand. It also has a very low electrical conductivity.
When deciding between cheap and expensive paint, it is important to consider the cost of labour and the number of coats required. Cheap paint may require multiple coats, increasing the time and effort needed to complete a project. In some cases, the cost of purchasing multiple cans of cheap paint may exceed the cost of a single can of expensive paint that provides better coverage.

Cost of pigment affects paint price
The cost of pigment does affect the price of paint. Pigments are granular solids incorporated into the paint to impart colour. Fillers are a type of pigment that serve to thicken the film, support its structure and increase the paint's volume. Fillers are usually cheap inert materials such as diatomaceous earth, talc, lime, barytes, or clay.
Cheaper paints tend to have less pigment and more filler. They may also include blanc fixe, a colourless pigment or filler to bulk out the mixture. The more filler a paint contains, the cheaper it is to produce, and the lower the quality.
The cost of the pigment itself, how difficult it is to obtain, and how in-demand it is, also changes the price of paint. For example, earth colours are cheaper pigments, so oil colours containing them will cost less. Conversely, paints made with more expensive pigments will be a higher series and cost more to buy.
The amount of pigment in paint also affects the number of coats required. Cheaper paints with less pigment may require multiple coats to achieve the desired colour, whereas more expensive paints with higher pigment content will provide better coverage and may only need one or two coats. Therefore, while the upfront cost of expensive paint may be higher, the overall cost of painting a room may be the same or less compared to using cheaper paint.
