Welcome to our blog post on the topic of whether you can put an oil-based stain over a water-based stain. Understanding the compatibility of different types of stains is crucial when it comes to achieving the desired finish on your woodworking projects.

In this post, we will explore the pros and cons of using oil-based stain over the water-based stain and provide helpful tips for those who are considering this method. The purpose of this post is to help you make an informed decision on the best type of stain to use for your specific project.


Understanding Oil-based and Water-based Stains

Stains are a popular choice for enhancing the natural beauty of wood and protecting it from damage. There are two main types of wood stains: oil-based and water-based. Understanding the differences between the two can help you choose the best option for your project.

Oil-Based Stains

Oil-based stains are made with mineral spirits or other solvents as the base. They are known for their deep penetration into the wood and provide long-lasting protection against wear and tear. Some of the benefits of oil-based stains include:

  • They offer a rich, warm color to the wood
  • They are more durable and long-lasting than water-based stains
  • They are easier to apply and penetrate deeper into the wood

However, there are also some downsides to using oil-based stains. They can take a long time to dry, and the solvents used in them can be flammable and emit strong odors. Over time, oil-based stains tend to yellowish or darken, which can impact the color of the wood.

Water-Based Stains

Water-based stains, as the name suggests, are made with water as the primary solvent. They are generally considered to be more environmentally friendly and safer to use than oil-based stains. Some of the benefits of water-based stains include:

  • They dry faster than oil-based stains
  • They emit fewer fumes and are generally considered safer to use
  • They won’t yellow or darken over time as much as oil-based stains do

However, water-based stains have some downsides as well. They are generally less durable and may not penetrate as deeply into the wood as oil-based stains. They may also raise the grain of the wood, which can require additional sanding.

Choosing the Right Stain for Your Project

When deciding between oil-based and water-based stains, consider the following:

  • The type of wood you are staining
  • The color you want to achieve
  • The level of durability you need
  • The environmental impact and safety concerns

Ultimately, the choice between oil-based and water-based stains will depend on your specific project and needs. Be sure to carefully consider the pros and cons of each type of stain before making a decision.

Can You Put Oil-based Stain Over Water-based Stain?

Staining wood surfaces is a great way to enhance their natural beauty and protect them from damage. If you’re considering using an oil-based stain over a water-based stain, here are the steps to follow:

Evaluate the condition of the surface

Before applying any stain, it’s important to evaluate the condition of the surface. If the water-based stain has not fully cured, or if the surface is not clean and free of debris, it may not be suitable for a new coat of stain.

Test a small area

If you’re unsure whether the surface is ready for a new coat of stain, or if the final color will be satisfactory, it’s best to test a small area first. Apply a small amount of the oil-based stain to a small, inconspicuous area and allow it to dry completely before evaluating the color and finish.

Clean the surface

If you decide to proceed with applying an oil-based stain over a water-based stain, the surface should be cleaned thoroughly before beginning. Use a clean, dry cloth to wipe away any debris or dust.

Lightly sand the surface

After cleaning the surface, lightly sand it with fine-grit sandpaper. This will help to smooth out any rough or uneven areas and provide a better surface for the oil-based stain to adhere to.

Apply the oil-based stain

Apply the oil-based stain in thin, even coats using a clean brush or cloth. Be sure to follow the manufacturer’s instructions for application and drying times.

Allow time to dry

Allow the oil-based stain to dry completely between coats, and be sure to allow enough time for the final coat to dry completely before using the surface.

By following these steps, you can successfully apply an oil-based stain over a water-based stain. Just be sure to evaluate the condition of the surface, test a small area, clean and sand the surface, apply the oil-based stain in thin, even coats, and allow plenty of time for the stain to dry. With a little patience and care, you can achieve a beautiful, even finish on your stained wood surface.

Alternative Solutions

Using a Sealer or Primer Before Applying the Oil-based Stain

One alternative solution to applying oil-based stain over water-based stain is to use a sealer or primer. This will create a barrier between the two types of stains and help prevent any potential issues with compatibility. A sealer or primer can also help to improve the overall finish of the oil-based stain.

Using a Water-based Topcoat Over the Oil-based Stain

Another alternative solution is to use a water-based topcoat over the oil-based stain. This can help to protect the oil-based stain and improve its durability. However, it is important to note that using a water-based topcoat may change the appearance of the oil-based stain.

Sanding Down the Water-based Stain Before Applying the Oil-based Stain

A final alternative solution is to sand down the water-based stain before applying the oil-based stain. This will remove the water-based stain and create a clean surface for the oil-based stain to be applied to. However, it is important to note that this solution is labor-intensive and may not be suitable for all projects.

Comparison of Oil-based and Water-based Stains

Note: This table compares the general properties of oil-based and water-based stains, but it is important to keep in mind that specific products may vary.


Can I use oil-based stains on outdoor wood surfaces?

Yes, oil-based stains are commonly used for outdoor wood surfaces such as decks and fences. They are known for their durability and resistance to weathering.

How long does an oil-based stain take to dry?

Oil-based stains typically take longer to dry than water-based stains. Drying time can vary depending on the type of wood, humidity, and temperature, but it can take anywhere from 8-24 hours for the stain to dry completely.

Can I use a water-based stain over an oil-based stain?

It is not recommended to apply a water-based stain over an oil-based stain, as the water in the water-based stain may react with the oil in the oil-based stain, causing the finish to appear uneven or blotchy. If you want to change the color of an oil-based stain, it is best to sand down the surface and start with a fresh coat of stain.

How do I remove oil-based stains from my hands?

To remove oil-based stains from your hands, use a mixture of equal parts dish soap and baking soda. Rub the mixture onto your hands, then rinse with warm water. Repeat as necessary.

How often should I reapply oil-based stain?

The frequency of reapplication will depend on the level of exposure to the elements and the level of foot traffic the surface experiences. It is recommended to reapply every 2-3 years for decks, and every 4-5 years for fences. Always wait for the wood surface to dry completely before reapplying.


It is possible to put an oil-based stain over a water-based stain, but it is important to understand the potential issues that may arise and take the necessary precautions.

Before deciding to apply an oil-based stain over a water-based stain, it is important to consider factors such as the type of wood and the desired finish.

Alternative solutions such as using a sealer or primer, using a water-based topcoat, or sanding down the water-based stain before applying the oil-based stain may also be considered.

In any case, it is important to properly prepare the surface and test the stains in a small, inconspicuous area before committing to a full application.

Overall, it is important to have a clear understanding of the properties and compatibility of different types of stains to ensure a successful and lasting finish.
