How to Tell Latex Paint or Oil-Based Paint on Walls or Trim?

latex paint oil based paint

Latex paint is a water-based paint that has been around since the 1950s. It is made with synthetic resins and pigments and dries to form a hard, durable film. 

Latex paint is the most popular type of paint for both interior and exterior applications because it is easy to apply, dries quickly, and cleans up easily with soap and water.

Oil-based paint, also known as alkyd paint, has been used for centuries. It is made with natural resins and pigments and dries to form a hard, durable film. 

In this article, we take a look at how to tell the main differences between these two types of paint.

Why It’s Important to Know the Difference

Latex paint and oil-based paint are two of the most popular types of paint on the market. Each has its own benefits and drawbacks, so knowing the difference is important.

Oil-based paint is more durable than latex paint, making it a good choice for metals, wood, and painting. It also takes longer to dry, so you’ll need to plan ahead if you’re using it. However, oil-based paint can be difficult to work with and cleanup can be tricky.

Latex paint is easier to work with and cleanup is simpler. It’s also more durable, so you’d better apply it to interior homes and on large surfaces. 

How to Tell by Appearance

When painting a room in your home, you will know what kind of paint to use by the appearance of the paint on the walls or trim. 

Oil based paint has a glossy finish when compared to latex paint. It is also thicker and takes longer to dry. When you apply oil based paint, you will need to use a different type of brush than what you would use for latex paint. If the paint is latex, it will have a chalky appearance .

In terms of color, latex paint typically has a white or off-white appearance, while oil based paints can be either clear or have a yellowish tint

Touch and Feel

If you’re not sure whether the paint on your walls is latex or oil-based, there are a few simple tests you can do to find out by touching and feeling the paint surface. 

For example, if the paint feels like it is still wet, it’s likely latex. If it’s dry and crumbly, it’s probably oil-based. You can also try to rub some of the paint off with a rag; if it comes off easily, it’s latex. 

Distinct Smell

Both latex and oil-based paints have their own distinct smells. A latex paint odor is much like that of new rubber. Oil based paints have a distinct solvent smell. But some people find the smell of oil-based paint more offensive than that of latex. 

How to Tell by Drying Time

Oil-based paint takes much longer to dry than latex paint. If paint takes longer than expected to dry or has a strong odor, it is likely to be oil-based.

Oil-based paint takes about six to eight hours to dry fully. This type of paint is difficult to work with because it takes a long time to set. Latex paint dries more quickly, usually within two to four hours. This makes it easier to work with, but it can be more difficult to apply evenly. 

How to Tell by Ease of Cleaning

The main difference between the two is that latex is water-based and oil-based is, well, oil-based. This means that latex will clean up with just soap and water, while oil-based paint will require paint thinner or mineral spirits.

Latex paint is also less smelly than oil-based paint, dries more quickly, and is generally less toxic. However, it isn’t as durable as oil-based paint and isn’t ideal for high-traffic areas or for painting outdoors.

Oil-based paint is more difficult to work with than latex paint, but it’s more durable and has a longer life span. 

Paint Durability

Durability is one of the key considerations when choosing paint. Oil-based paint is generally more durable than latex paint. It can withstand more wear and tear, making it ideal for high-traffic areas like kitchens and bathrooms. 

Latex paint is more susceptible to chipping and flaking, so it’s not the best choice for areas that see a lot of activity. 

What Is Better for Walls and Trims: Latex Paint or Oil Based Paint?

There are a few things to consider when deciding between latex paint and oil-based paint for walls and trim:

  • The sheen, or glossiness, of the paint is one factor. Latex paint has a more matte finish, while oil based paints are shinier. 
  • Another consideration is drying time; oil based paints take longer to dry than latex paints. 
  • Clean up is also something to think about; cleaning up oil based paint requires mineral spirits, while latex paint can be cleaned up with soap and water.

Some experts say that oil-based paint is better for walls and trims because it is more durable and easier to touch up. Latex paint can sometimes be difficult to touch up without leaving an obvious mark. 

When it comes to choosing between latex paint and oil-based paint, it really depends on the project and the look you are going for. 


There are two main types of paint: latex and oil-based. Each has its own advantages and disadvantages that you should consider before beginning a painting project.

Latex paint is water-based, so it is easier to clean up and is less smelly than oil-based paint. It also dries more quickly, so you can get started on the next coat sooner. However, latex paint isn’t as durable as oil-based paint, so it isn’t a good choice for high-traffic areas or areas that will be exposed to moisture.

Oil-based paint takes longer to dry, but it is more durable than latex paint. It is also a good choice for painting surfaces that have already been primed with an oil-based primer. However, oil-based paints are more difficult to clean up and they have a strong smell.
