You will find three reasons why you can use stain over linseed oil. Besides these reasons, you will also find other factors that will insist you not use any stain over the linseed oil. That’s true; you cannot ignore those reasons.

But if you want to stain over the linseed oil, you must avoid those reasons and focus on the positive factors.

Oil-Based Primer:

The first reason you can use stain over the linseed oil is because of the oil-based primer. You will find both water-based and oil-based primers to stain over the linseed oil. You need to choose the oil-based primer to stain over the linseed oil.

It will stick to the hard surface and give you the best protective stain. You can also use the gel stain to get similar durability and strong stain. So, both the gel stain and the oil-based primer can be used over the linseed oil.

Hard Layer:

Another reason you can use stain over the linseed oil is the hard layer. When you apply the linseed or flax oil over the wood, you will get a hard layer once it dries properly. It will help to stick to the stain firmly and not mess up the surface.

It will ruin the furniture or the targeted surface. Instead, the stains will enhance the beauty of the linseed oil, which is why you can use the recommended stain on the linseed oil.

What stain to use over linseed oil?

Linseed oil should not be stained with a regular stain after applying it. Linseed oil does not work well with conventional stains that are either water- or oil-based. This is because linseed oil has a finishing quality to penetrate the surface deeply.

Additionally, drying times for linseed oil can be quite lengthy, which means that the top layer, once completely dry, will be quite rigid.


Linseed oil is another medium that sealants like polyurethane perform admirably. In most cases, only light sanding is required. Linseed oil can have polyurethane applied on top of it.

However, before applying the polyurethane, you need to make sure that the linseed oil has been allowed to dry completely. Linseed oil is compatible with both water-based and oil-based polyurethane so you can use either one.

Gel Stain:

When staining with linseed oil, you should only use topical stains such as a gel. Gel stain is a varnish made of oil (similar to polyurethane) to which a colorant has been added.

It is intended to adhere to the surface of the wood rather than being absorbed by it, and as a result, it is significantly thicker than conventional wood stain. This results in less blotching, a common issue with traditional stains.

How to stain over linseed oil?

You can stain over the linseed oil by following the below steps.

Choose Stain:

If you want a darker finish with linseed oil, you should use a gel-based stain, a glaze, or one that is water-based. The color that is produced by stains of this kind is typically darker. 

Put on Stain:

Use a foam brush or a cloth to apply a thick coat of stain over the linseed oil. Use a foam brush or an old material to reduce the appearance of brush strokes after applying the stain remover.


Allow the stain over linseed to set for between 20 and 24 hours. Waiting this amount of time will guarantee that the stain is completely dry. You won’t get a smooth coat when applying the sealer if it hasn’t dried entirely first.

Add Stain:

If necessary, apply an additional layer of stain. If you use multiple coats, the grain of your wood may become more difficult to see; however, applying a second coat may help you achieve a darker color if that is the look you are going for.

Use Sealer:

To achieve a glossy finish, apply a sealer over linseed that is either water- or oil-based. Using a topcoat will prevent the stain over linseed from evaporating while also providing a smooth and glossy finish.

What finish can be applied over linseed oil?

You can apply polyurethane over linseed oil because it has the characteristics to stick with this, and you need to use oil-based polyurethane there.

In general, polyurethane safeguards the wood from scratches, while linseed oil is known to seal the wood grain. You can put polyurethane over linseed oil, yet you want to guarantee that the linseed oil is dehydrated before polyurethane application.

Also, two kinds of polyurethane exist in the nearby market; these are water-based and oil-based polyurethane.

So you have to use oil-based polyurethane here because it works over linseed oil strictly. You can apply polyurethane over boiled linseed oil since bubbled linseed oil dries quicker than crude linseed oil.

Final Thoughts

Although you can stain over the linseed oil, you must maintain some roles. You cannot use all the common stains over the linseed oil. Only the gel stains and other oil-based primers can be used. If you have any other choice, you must check the compatibility before choosing it.
