We understand with the variety of protective door finishes available that it can be quite overwhelming, and you’ll more than likely be stood in the aisle of your local hardware store scratching your head and daydreaming about something else more exciting. We’re here to help you avoid the internal conversation in your head that goes something like – “Do I need protection oil and a base coat?” “How do I choose between satin, semi-gloss or high gloss?”

Top Tip – All unfinished doors need a protective coating before you install them. This will also mean that you have to stain, varnish, wax or paint them to your desired requirements.

What To Consider

The Protective Coating

As we mentioned briefly earlier in this article, with unfinished doors they need a protective coating. This allows for a protective layer which not only protects, but creates a unique appearance too. It's important to keep your door protected from moisture, and wear and tear.

Hardwax Oils

There are three brands best known for their door oils - Treatex, Impranol and Osmo. All of these oils are preferred finishing solutions for internal doors. Most are a mix of oil an wax, which means that it will soak into the wood surface and therefore provide a hard wearing wax layer. You will come across a variety of oils in different shades, such as clear satin and clear matt finishes, see below for quick descriptions of what they can provide for your door.

Satin - Provides a silky smooth finish and reflects more light which is ideal if you're looking to create a more bright and airy living space.

Matt - This finish is able to cover imperfections in the surface and application. It's very easy and simple to touch up the finish if required.

Semi gloss and gloss - These finishes provide high resistance to moisture and are often used for kitchen and bathroom doors.

Finishes By Shades

Door finishes are available by shade, so if you have an oak door that is light in colour and you want to maintain the natural look and feel, the chances of you using a dark oil or wax is very unlikely. There are a range of door finishes you can look at by shade. These are:

Staining & Varnishing

Wood stains and varnishes are available in a large range of colours. Depending on what colour you are looking to stain or varnish your door with, you can always dilute the stain in order to achieve a lighter shade or tone which better matches your preferred colour. It's important to note that colours will look different on different woods, so be sure to test colours beforehand.

Top Tip - Always apply the stain in the direction of the grain.
