Introduction
When it comes to painting, the type of paint you choose can have a significant impact on the final outcome of your project. One popular choice is oil-based paints, also known as alkyd paints, which have been used for centuries. In this article, we will examine the benefits and drawbacks of using oil-based paints, as well as suggest suitable applications for this type of paint.
What are oil-based paints?
Oil-based paints are made up of resins, oils, and solvents, which work together to create a durable, glossy, and high-quality finish. These paints are resistant to moisture and wear, making them perfect for use in high-traffic areas such as kitchens and bathrooms.
Brief history of oil-based paints
Oil-based paints have been around for centuries, with the ancient Egyptians and Greeks using them in their artwork. In the 20th century, oil-based paints became increasingly popular due to their ability to create a long-lasting, high-quality finish.[i] [ii] [iii]
Benefits of Oil-based Paints
Oil-based paints have some disadvantages, but they also offer several advantages that make them a popular choice for many painting projects.
Durability
Oil-based paints are highly durable, making them ideal for use in areas that experience high traffic or frequent contact. They are particularly well-suited for painting trim work, cabinetry, and doors, as they can withstand wear and tear better than other types of paint. In addition, oil-based paints have a longer lifespan than water-based paints, which can chip or fade over time.[iv]
Gloss Retention
Oil-based paints create a glossy, high-quality finish that retains its shine over time. This feature makes them ideal for use on furniture and other decorative items that require a smooth, shiny finish. Oil-based paints can be used to create a mirror-like finish that is not achievable with other types of paint.[v]
Easy Application
Despite the misconception that oil-based paints are difficult to work with, they are actually relatively easy to apply. They can be brushed or rolled onto surfaces, and they have good coverage, which means that you can often achieve the desired look with fewer coats than with other types of paint. This ease of application makes oil-based paints a good choice for both professional painters and DIY enthusiasts.[vi]
Negatives of Oil-based Paints
When it comes to painting, oil-based paints are a popular option, but they do come with their downsides. Here are a few negatives to consider:
Strong Odour
Oil-based paints emit strong fumes that can be unpleasant and harmful if inhaled excessively. Proper ventilation and personal protective equipment are necessary when using them. For those with sensitivities to strong smells, consider low VOC paints, which emit fewer fumes and are better for indoor air quality.[vii]
Long Drying Time
Unlike water-based paints, oil-based paints take a while to dry completely, sometimes several hours or even days. This may not be ideal for those with tight project deadlines or for multi-coat painting projects. To speed up the drying process, consider using a paint thinner or drying agent.[viii]
Toxicity
Oil-based paints contain solvents and other chemicals that can pose health risks if ingested or inhaled. Respiratory problems, headaches, and nausea are common symptoms associated with improper use. Take necessary precautions such as wearing protective gear and disposing of paint and solvents properly to avoid contaminating the environment.[ix]
Clean-up with Solvents
Cleaning up oil-based paints is a messy and time-consuming process that requires solvents such as mineral spirits or turpentine. Proper disposal of these solvents is crucial to avoid polluting the environment. To avoid these hassles, consider using water-based paints that can be cleaned up with soap and water.[x]
Best Applications for Oil-based Paints
Although there are some drawbacks to oil-based paints, they have many applications where they shine. Here are some of the best uses for oil-based paints:
Trim work
Oil-based paints are ideal for trim work, such as baseboards and crown moulding, due to their durability and ability to create a smooth, glossy finish. They also provide good adhesion and resistance to chipping and peeling, making them an excellent choice for high-traffic areas.
Furniture
Oil-based paints are a great option for painting furniture, creating a high-quality, durable finish that resists wear and tear. They offer excellent coverage, and their slow drying time allows for a smooth, brushstroke-free finish. Additionally, oil-based paints are resistant to water and stains, making them a popular choice for outdoor furniture.
Cabinetry
Oil-based paints are commonly used for painting cabinetry, providing a smooth, glossy finish that is resistant to moisture and wear. They are also highly durable and easy to clean, making them an excellent choice for kitchen and bathroom cabinets.
Doors
Oil-based paints are perfect for painting doors, creating a high-quality, durable finish that is resistant to wear and tear. They also offer excellent adhesion, allowing for a long-lasting finish that can withstand heavy use.

Conclusion
Summary of Key Points
Oil-based paints are known for their durability and ability to create a glossy, high-quality finish, making them ideal for high-traffic areas like doors, trim work, and cabinetry. However, they also have some drawbacks such as a strong odour, long drying time, toxicity, and the need for solvents for clean-up.
Final Thoughts and Recommendations
Despite their negatives, oil-based paints are still a good choice for projects that require a long-lasting, high-quality finish. Safety precautions such as proper ventilation and use of personal protective equipment should always be taken when using them. Additionally, proper disposal of solvents used for clean-up is crucial to avoid environmental contamination. In summary, oil-based paints remain a popular and effective choice for many painting projects and using them responsibly and safely can lead to excellent results.
