Oil-based primer is an essential step in preparing any surface for painting. Whether you are a professional contractor or a DIY enthusiast, understanding when to use an oil-based primer and how it can help can make a big difference in the final outcome of your project. This article will explain what oil-based primer is, when to use it, and how it can help you achieve a flawless finish. We will also provide a step-by-step guide on how to apply oil-based primer and the benefits and drawbacks of using it.
Oil-based primer can be used on various surfaces, including wood, metal, and drywall. It can also be used on previously painted surfaces in good condition. It is used when painting over stains, as it will help to block the stain from bleeding through the paint. It can also be used on new construction, as it will help to seal the surface and provide a good foundation for paint.
Types Of Primers
- Oil-based primer
- Water-based primers
- Latex primers
- Shellac-based primers
Water-based primers are thinner and easier to clean up if you spill them. They are made from latex, which is a type of rubber. They are less likely to cause allergic reactions than oil-based primers.
Latex primers are a good choice for painting over latex paint. Latex primers are made from acrylics and provide good coverage. They’re also easy to clean up if you spill them. However, they’re not as effective at blocking stains.
Shellac based primers are the most durable and provide the best coverage. However, they’re also the most difficult to cleanup if you spill them. They are made of a resin that comes from the lac bug.
What Is Oil-Based Primer?
Oil-based primer is a type of primer that is made from a mixture of oil and solvent. Unlike water-based primers, which use water as a base, oil-based primers have a longer drying time and a strong odor.
However, oil-based primers provide better adhesion and are more durable than water-based primers. Oil-based primers are commonly used for surfaces that require a strong bond and for surfaces that have been previously painted with oil-based paint.
One of the key benefits of using oil-based primer is that it provides a strong bond between the primer and the surface. This bond helps the paint adhere better to the surface, resulting in a longer-lasting finish.
Additionally, oil-based primer provides better resistance to moisture, making it ideal for use in areas with high humidity or frequent exposure to moisture.

When To Use Oil-Based Primer
One of the most important decisions you will make when starting a painting project is choosing the right primer. While water-based primer is a popular choice for many surfaces, there are some instances where oil-based primer is the better option.
One of the best surfaces for oil-based primer is wood. Whether you are painting a new piece of furniture or refinishing an old one, oil-based primer provides a strong bond that helps prevent paint from peeling and chipping over time. Additionally, oil-based primer is ideal for surfaces that have been previously painted with oil-based paint, as it helps to create a strong bond between the old and new layers of paint.
Another surface that is well-suited for oil-based primer is metal. Oil-based primer provides excellent adhesion and corrosion resistance, making it ideal for use on metal surfaces such as pipes, radiators, and metal siding.
Here are some other situations where you might need to use oil-based primer:
- When painting over a stained surface
- When painting over bare wood
- When painting metal
Difference Between Oil-Based and Water-Based Primers
1. One of the key differences between oil-based and water-based primer is the drying time. Oil-based primer typically takes longer to dry than water-based primer, which can be a drawback for some projects.
2. Additionally, oil-based primer has a strong odor that can linger for several days after application, which can be a concern for some people.

4. Additionally, oil-based primer provides better resistance to moisture, making it ideal for use in areas with high humidity or frequent exposure to moisture.
How To Choose the Right Primer
1. When it comes to choosing the right primer, there are several factors to consider. One of the most important factors is the type of surface you will be painting. For example, wood surfaces are well-suited for oil-based primer, while metal surfaces are well-suited for water-based primer.
2. Another important factor to consider when choosing a primer is the type of paint you will be using. If you will be using an oil-based paint, it is recommended to use an oil-based primer. If you will be using a water-based paint, a water-based primer is a better option.
3. Consider the environment in which you will be applying the primer and paint. For example, if you will be working in a well-ventilated area, an oil-based primer may be a better option. If you will be working in a confined space or an area with limited ventilation, a water-based primer may be a better choice due to its low odor and quick drying time.

How To Apply Oil-Based Primer
Oil-based primer is a bit trickier to work with than water-based primer, but with the right tools and techniques, it can be applied with great success. Here is a step-by-step guide on how to apply oil-based primer.
Before you start, make sure you have all the supplies you need. You will need
- Oil-based primer
- Paintbrush or roller
- Lint-free cloth
Step By Step Guide:
Before you begin, it’s important to read the instructions on the primer can. This will give you an idea of how long the primer needs to dry before you can apply the paint.
Once you’ve read the instructions, follow these steps:
Step 1: Start by Stirring the Primer
This is important because you want to make sure the primer is mixed properly before you start painting.
Step 2: Prepare the Surface
Start by cleaning the surface that you’ll be priming. This will remove any dirt, dust, or grease that could prevent the primer from adhering properly. Once the surface is clean, use a lint-free cloth to remove any residual dust.
Step 3: Pour A Small Amount of Primer into A Paint Tray
Once the surface is prepared, you can start priming. Pour a small amount of primer into a paint tray and load your brush or roller.
Step 4: Apply the Primer
Now it’s time to apply the primer. Use long, even strokes to apply the primer to the surface.
Step 5: Allow the Primer to Dry
Once you’ve applied the primer, allow it to dry according to the instructions on the can. Once it’s dry, you can start painting.
NOTE: You can use mineral spirits or paint thinner to thin the primer if it gets too thick and to remove the oil-based primer from your hands, tools, and surfaces. Be sure to follow the manufacturer’s instructions when using these products.
