Oak entrance doors add a touch of elegance and durability to your home. But like any exterior wood, oak needs proper care to withstand the elements and maintain its beauty. In this article we reveal how to finish oak doors, which is the best treatment for external oak doors and tips to keep yours looking incredible.

Preparation is Key

Checking your oak doors
Inspect the door after delivery to see if it is pre-sanded. If it has not been sanded, do so before hanging the door. Always sand with the grain, and use wire wool rather than sandpaper if possible. If you need to store the door for a while before hanging it, keep it in a cool, dry room and leave it in its original packaging. Protect the door from damp and temperature fluctuations because these can warp the door. Never store a door upright – always lie it flat.

Following the proper instructions
Each door manufacturer has their own requirements and recommendations for caring for their products. The instructions below will give you an idea of how to treat and care for a door, but they are not a substitute for your manufacturer’s instructions. Read the documentation that came with your door carefully, and take care to follow all of their guidance, otherwise your door’s warranty will be void.

Preparing your doors for treatment
Before applying any products, ensure your door is clean and dry. Dirt, grime, and moisture can hinder the treatment’s adhesion. Wipe down the door thoroughly with a damp cloth and allow it to dry completely. Also, inspect the door for any damage like cracks, loose hinges, or peeling paint. Address any issues before proceeding.

Gathering your tools
You’ll need your chosen primers/basecoats/ stains or paints, paint brushes (thin ones for the edges, and a larger one for the face of the door), sand paper or wire wool and dust covers/masking tape to protect areas near the door

What is the best finish for an external oak door?

There are two main options for treating external oak doors: paint and oil.

Paint provides a solid colour and excellent protection against UV rays and moisture. However, it requires more frequent maintenance compared to oil which enhances the natural grain of the wood and offers good weatherproofing. Oil treatments penetrate deeper than paint, but require more frequent reapplication.

Broadly, if you prioritise maintaining the natural wood look, choose oil. This option offers a natural, translucent finish, while paint provides a solid, opaque colour.

However, if you live in a harsh climate with extreme sun or rain, a high-quality paint might be a better choice for long-term durability. But bear in mind, oil does require more frequent reapplication, so factor in the time and effort for maintenance.

Ultimately, the best way to choose is to weigh your priorities and preferences. You can also consult a paint or homeware professional for recommendations based on your specific door and climate.

Oil Treatment Application Tips

Apply a wood sealant specifically designed for end grain to prevent excessive absorption and cracking. Next, use a high-quality oil with UV protection. Apply thin, even coats following the wood grain with a brush or lint-free cloth. Apply 2-3 coats, allowing each coat to dry completely between applications (refer to the manufacturer’s drying time recommendations). For extra protection and a glossier finish, apply a top coat specifically designed for the chosen oil.

Be sure to work in a well-ventilated area while wearing gloves and a mask for protection. Choose a mild, dry day to apply treatments, taking care not to apply anything in direct sunlight. When you’re finished, clean your brushes and tools thoroughly.

Maintaining Your Treated Door

Regularly clean your door with a damp cloth to remove dirt and cobwebs. Reapply oil treatment every 1-2 years or as per the manufacturer’s recommendations. Repaint the door every 5-7 years, depending on the paint quality and weather conditions.

Understanding the Benefits

External oak doors boast a number of advantages that make them a worthwhile investment for your home.

Durability
Oak is a naturally hard and strong wood, known for its exceptional resistance to wear and tear. An external oak door can withstand harsh weather conditions, bumps, and scratches, providing long-lasting performance.

Weather Resistance
Oak is naturally resistant to moisture, rot, and insect infestation. This makes it a great choice for external doors that have to endure the elements year-round, without succumbing to warping or decay.

Insulation
Solid oak acts as a natural insulator, helping to regulate the temperature inside your home. In the winter, it keeps the warm air in, and in the summer, it helps keep the cool air in, contributing to energy efficiency.

Aesthetics
Oak has a beautiful, timeless grain pattern that adds a touch of elegance and sophistication to any home’s exterior. It comes in a variety of natural finishes and can also be stained or painted to suit your style.

Increased Security
The inherent strength of oak makes external oak doors naturally more secure than doors made from softer materials. This provides peace of mind knowing your home has a strong barrier against potential intruders.

Investment Value
A high-quality external oak door can increase the value of your property. The classic beauty and durability of oak are seen as desirable features by potential buyers.

Low Maintenance
While requiring occasional cleaning and reapplication of treatment (depending on your chosen finish), external oak doors generally require minimal maintenance compared to doors made from other materials.

Environmentally Friendly
Oak is a sustainable choice if sourced from well-managed forests. Compared to some less durable materials that might need frequent replacement, a well-maintained oak door represents a more eco-friendly option.
