The UV rays and heat from direct sunlight, rain, snow, and extreme temperature changes can be very hard on exterior wood doors, especially those with clear finishes. To ensure durability and attractiveness, it is recommended to sand the door down and finish it with multiple coats of an exterior spar varnish made for boats.
The best protection for an exterior door is opaque paint, which requires constant maintenance. A storm door can also help protect the door from the elements. Apply the paint with a synthetic brush in the direction of the grain and leave it to dry for four hours. Apply a second coat if the front door is bare wood, as you will still see the grain after two coats.
When selecting a finish for wood doors, there are two clear paths: natural or synthetic. Each option has advantages and disadvantages in terms of durability, toxicity, and ease of application. In my opinion, spar varnish provides the best clear coat protection against water.
To properly seal in the stain, you will need to apply a clear coat. For exterior doors, it is highly recommended to use McCloskey’s spar varnish brushed like glass. Thin the first coat on new doors so it will penetrate, sand, and brush two finish coats. After sanding the entire door to 150 grit with a random-orbit sander, it is crucial to sand by hand every square inch with 180-grit and 220-grit paper to bring the stain to the surface.
Polyurethane is one of the best options for protection and durability, but it takes days for oil-based polyurethane to set properly.

What is the best coating for exterior wood doors?
Polyurethane is a durable, moisture-resistant clear finish that is particularly well-suited for use on wooden entry doors. To apply, two coats should be applied, with a light sanding between each coat. The application of a fresh coat should be repeated every two years. The product enhances the natural beauty of wood, provides excellent durability, and is straightforward to apply and maintain.
What to use to protect an exterior wood door?
To maintain the shine of your exterior wood doors, it’s recommended to polish them every two to three months. Wood furniture polish or wax products can be used, with varnish polish being better for sun-prone doors. Wax-based polish is ideal for hiding scratches on older wood doors, while lacquer polish is quick-drying and ideal for keeping pets or children away.
Refinishing your wood door every few years is essential when it shows signs of wear. This process can be done annually, bi-annually, or bi-annually, depending on the climate and usage. The process involves stripping the old finish, sanding down the wood surface, removing dust, wiping down with a lint-free cloth, applying two to three coats of exterior wood finish or paint to the edges, rehanging the door, applying finish to the front and back, and replacing the hardware once the door is dry.
What is the best way to finish an exterior wood door?
To seal in a stain on exterior doors, apply a clear coat using an outdoor rated polyurethane 2 part clear coat. This hardens and protects against water and sun. Apply the first coat lightly using an airless sprayer or a gravity fed HVLP gun with an air compressor. Scuff the entire door with a 180 grit sanding sponge after 15-30 minutes to knock down raised fibers. This step is crucial for a smooth final product.
After scuffing, wipe the door down with a clean rag to remove chalky dust. Apply a medium to heavy final coat to the entire door and allow it to dry. Curing time takes over 24 hours and continues to harden over the next few days or weeks. Avoid excessive abuse until the door has had 2 weeks to fully cure.
How do you weatherproof a wooden exterior door?
To waterproof a wooden door, use varnish or lacquer for a long-lasting, waterproof, and weatherproof finish. While it may not provide the same visual appeal as oil or paint, it provides the strongest protection. Regular maintenance and refinishing are crucial for long-term protection against rain and damp. Inspect the door regularly to see if moisture is still beading on the surface, and if it starts to absorb, refinish with another layer of paint, varnish, or oil.
How do you make wood last forever outside?
To prolong the lifespan of wood outdoors, it is crucial to ensure it is thoroughly dried to prevent shrinkage. Regular use of preservative treatment can prevent decay, which can be achieved using high-quality preservatives. Staining is another important aspect of wood preservation, and coastal considerations should also be considered. Proper protection from moisture, salt, sun, rain, and frost can significantly impact the stability and appearance of wooden structures. To ensure the longevity of wood, it is essential to avoid purchasing green wood and follow simple rules on wood care.
What is the best finish for natural wood doors?
For those who prefer an all-natural oil, Tung Oil is the optimal choice. Other suitable oils for doors, such as boiled linseed oil, can be selected to achieve desired wood finishes, including darkening and imparting a subtle golden hue. All of our oils are suitable for use on doors.
How do you weatherproof old wooden doors?
Weatherstripping is a crucial component in maintaining energy efficiency in homes. It helps seal small gaps around doors and windows, keeping warm air in during winter and cool air in during summer. There are various types of weatherstripping available, including adhesive-backed foam tape, door sweeps, and mechanical weatherstripping. If you notice drafts in your entry doors, it may be time to replace your weatherstripping.
This simple step-by-step guide will help you block drafts, lower energy bills, and keep moisture and pests out. Wood doors, which can expand and contract with changing temperatures, are particularly susceptible to weatherstripping.
Is it better to stain or paint exterior wood door?
Painting your front door is a versatile and cost-effective choice for a well-designed and durable door. It offers a wide range of color options and can complement your home’s exterior, ensuring durability and ease of maintenance. However, staining is generally more expensive due to the labor-intensive process and ongoing maintenance requirements. Professional wood refinishing jobs can vary greatly in cost, reflecting the level of detail and craftsmanship involved. Stained doors require regular upkeep to maintain their appearance, adding to the overall expense. Overall, choosing paint over staining is a wise decision for a well-designed and cost-effective door.
How to make a wooden door waterproof?
Sealing and caulking wooden doors and windows is a crucial step in weatherproofing them, as water can seep through gaps and cracks, causing damage and potential rot. High-quality sealants and caulking compounds can prevent water infiltration. Protective coatings and varnishes are essential for protecting wood from moisture and UV rays, which can cause discoloration and deterioration over time. These products should be specifically designed for exterior use and provide long-lasting protection.
Thorough preparation of the surface is essential for maximum adhesion and effectiveness. Regular maintenance and reapplication of these protective solutions are necessary to maintain their weather-resistance properties and protect the wooden fixtures against the outdoor elements.
What lasts longer, exterior paint or stain?
Solid stain offers benefits like protection, durability, and a wider color selection, but it fades faster and requires repainting sooner. It can appear like paint when applied over painted or sealed surfaces, but has a shorter lifespan and less protective qualities. Paint is typically the best option, but solid stain can be useful for retaining wood texture on bare surfaces. For more information on solid stain vs exterior paint and the best options for your home, contact Dunbar Painting’s experienced team.
How do you protect raw wood outside?
To protect your outdoor wood from woodworm and rot, use a biocidal cleaner and an undercoat wood preservative. Stain the wood to give it a new look, and choose from wood oils, varnishes, wood sealers, and decking oils to balance protection and durability. Timber is a versatile construction material used for thousands of years, but most of it is susceptible to decay if left untreated. This is due to the focus on faster-growing softwoods like pine, which is not enough sustainable wood to meet demand.
Most buildings in the UK contain untreated timbers that can be affected by woodworm or damp, dry, or wet rot. These organisms negatively impact structural strength and can even cause structural damage. It is crucial to take action when active timber decay is identified to prevent structural damage to the building.
