Wipe-On Poly over Danish Oil – What Can Go Wrong?

Woodcrafts / By

Wipe-on poly and Danish oil are two popular finishes for woodworking projects. They are both easy to apply, and they give the wood a beautiful, natural sheen. However, can you use both of them together?

The answer is yes, but there are a few things you need to be aware of to avoid any potential problems. In this article, we’ll go over what can go wrong if you use wipe-on poly over Danish oil, and how to avoid those issues.

First, let’s take a quick look at some of the main properties of wide-on poly and Danish oil so that we can better understand how to apply them together.

What is wipe-on poly and which projects is it used for?

A wipe-on poly is standard polyurethane with one key difference – mineral spirits have been used to thin down the product to make it more user-friendly and easier to apply with a rag.

Despite having several advantages such as a very smooth finish, good durability, and moisture resistance; wipe-on polyurethane should not be used for all projects.

For instance, wipe-on poly is not ideal for projects that will see a lot of wear and tear such as floors or countertops since it is not as durable as other types of polyurethane. It is also not the best choice for outdoor projects since it is not UV resistant and can yellow over time when exposed to direct sunlight.

Now, where wipe-on poly truly shines is smaller projects that do not get a lot of daily wear and tear. For example, wipe-on poly is a solid choice for projects such as:

  • Furniture
  • Cabinets
  • Doors
  • Trim
  • Moldings

What is Danish oil and which projects is it used for?

Danish oil is a type of finish that penetrates deep into the wood grain to protect it from within. It is made up of a blend of oil and resin and is available in both clear and tinted versions.

Danish oil is often used on projects that will be exposed to a lot of water or moisture such as:

  • Kitchen tables
  • Bathroom vanities
  • Outdoor furniture
  • Wooden boat hulls

Why use wipe-on poly over Danish oil?

Now that we know a bit more about Danish oil and wide-on poly, let’s take a look at why you might choose to use them together.

One of the reasons you might choose to use wipe-on poly over Danish oil is for the added protection it can provide. Danish oil does a great job at protecting the wood from within but it can leave the surface vulnerable to scratches and other damage.

Adding a layer of wipe-on poly over the Danish oil can help to create a barrier that will better protect the wood from everyday wear and tear.

Another reason you might choose to use wipe-on poly over Danish oil is for the added shine it can provide. Danish oil gives the wood a natural, satin finish but if you are looking for a bit more shine, wipe-on poly can give your project that extra bit of luster.

Lastly, using wipe-on poly over Danish oil can help to extend the life of the Danish oil finish. Danish oil will eventually need to be reapplied but adding a layer of wipe-on poly can help to extend the time between reapplications.

Now that we know why you might choose to use wipe-on poly over Danish oil, let’s take a look at some of the common mistakes to avoid when applying the two finishes.

Wipe-on poly over Danish oil – what can go wrong?

1. Not allowing the Danish oil to fully cure

Danish oil needs time to fully cure and harden before you can apply a layer of wipe-on poly over it. If you try to apply the wipe-on poly too soon, you run the risk of the two finishes not bonding properly and the wipe-on poly peeling off down the road.

To avoid this problem, make sure you allow the Danish oil to fully cure according to the manufacturer’s instructions before applying the wipe-on poly.

2. Not sanding between coats

If you are applying multiple coats of Danish oil or wipe-on poly, it is important to sand between each coat. This will help to create a smooth surface and ensure that the subsequent coats bond properly.

3. Applying too much finish

When it comes to both Danish oil and wipe-on poly, less is more. If you apply too much finish, it can take longer to dry and can result in a sticky or tacky surface.

4. Not wiping off the excess finish

After you have applied the Danish oil or wipe-on poly, make sure to wipe off any excess finish with a clean, lint-free cloth. Allowing the excess finish to remain on the surface can result in a dull or streaky finish.

5. Applying the finish in direct sunlight

Applying Danish oil or wipe-on poly in direct sunlight can cause the finish to dry too quickly and can result in an uneven or streaky finish. If possible, apply the finish in a well-ventilated area out of direct sunlight.

By following these simple tips, you can avoid common mistakes and get the best results when using wipe-on poly over Danish oil.

How to apply wipe-on poly over Danish oil?

Now that we have an idea of what common mistakes to avoid, let’s take a look at the proper way to apply wipe-on poly over Danish oil.

Depending on your project, you should start by applying a thin layer of Danish oil with a clean, lint-free cloth or brush. Make sure to work the Danish oil into the wood in the direction of the grain and to wipe off any excess that is not absorbed by the wood.

Allow the Danish oil to fully cure according to the manufacturer’s instructions before applying a layer of wipe-on poly.

To apply the wipe-on poly, start by stirring the can thoroughly and then pour a small amount into a container. Using a clean, lint-free cloth or brush, apply a thin layer of wipe-on poly over the Danish oil in the direction of the grain.

Make sure to wipe off any excess poly that is not absorbed by the wood and to allow the finish to dry completely before applying additional coats.

By following these simple steps, you can successfully apply wipe-on poly over Danish oil and create a beautiful, durable finish for your project.

If you want your finish to have that little extra bit of protection, adding a layer of wipe-on poly over Danish oil can be a very useful option. Just remember to avoid common mistakes, such as not allowing the Danish oil to fully cure or not sanding between coats, and you will be on your way to a beautiful finish.
