Best Finish for Exterior Mahogany Door Buyer’s Guide

When choosing the best finish for exterior mahogany doors, you need to consider critical factors. These factors will help you decide if the finish is the right one for the job or not. Below are some of the factors that you should consider;

Type of Exterior Finish

Some exterior finishes come in two-parts while others are used without mixing. Although finishes that are used without mixing are easier to use, two-part finishes offer optimal abrasion resistance and dry rapidly. When mixed in the right combination, two-part finishes provide the best coating result, unlike one-part finishes.

UV Protection

Exterior finishes with UV protection make them suitable for outdoor utilization. UV rays are real threats to wood and can cause irreparable damage to the wood. The best finish for the exterior mahogany door must come with UV blockers. It prevents warping and the growth of mold in the wood to a great extent. You should note that finishes with UV blockers don’t totally prevent sun rays from reaching the wood.

When choosing an exterior finish, ensure that it comes with UV absorbers.


Since it’s a finish for exterior use, you need to make sure it’s durable enough to withstand abrasion and scratches. In addition to that, it should last for an extended time. This will help cut down on expenses in the long run.

Ease of Use

Not all exterior finishes are simple to use. Contrarily, you’ll find some that you may need to thin or mix with one solvent or the other before applying. Additionally, some of these products may prefer a method of application that you may not know.

When choosing an exterior finish, ensure that it’s convenient to use. Also, ensure that such a product comes with a manual or an instruction guide so that you won’t have issues applying the product. When mistakes occur, you should find handling the issue comfortably.

Drying Time

Every finish for exterior purposes has its drying time. Most exterior finishes dry rapidly but others take a longer time than usual to dry. You should avoid this type of exterior finish, as it can be easily messed up by debris and dust.

How to Refinish Exterior Mahogany Doors

Refinishing mahogany doors is one thing that most people are not familiar with. However, it’s not as difficult as you may think. We will teach you how to refinish the hardwood door in simple steps.

What do You Need?

  • Screwdriver or center punch
  • Chemical strippers
  • 80-grit, 150-grit, 180-grit, and 220-grit sandpaper
  • Wood stain
  • Paintbrush
  • Rag
  • Marine Spar varnish

Remove the Door Off the Hinges

First off, remove the door off the hinges. You can use a screwdriver or a center punch for the removal process. You’ll feel more balanced refinishing the door this way.

Prepare the Surface

Once you have successfully taken the doors out, remove all the hardware and prepare the surface for some sanding. Sand evenly using 80-grit sandpaper to remove the existing stains and sealers. Once you are done, check to see if there are gaps or holes on the door. If there are, fill them up with wood putty and sand with 150-grit sandpaper until a smooth surface is achieved.

If you find using sandpaper inconvenient, you can opt for a chemical paint stripper. A chemical stripper is a fantastic alternative to sandpaper and works best if you need to remove stains or sealers from places with fine details like a mahogany door. Sanding is more exhausting and time-consuming.

Before you can use a chemical stripper, wear thick protective gloves, overalls, and a respirator. Also, you should work in a ventilated area, as the chemical components are toxic. To get started, purchase a gel stripper and pour the required content into a shallow glass bowl.

Apply the stripper using a paintbrush from the top to the door’s bottom. But remember to follow the instructions as stipulated by the brand on the label. After painting, wait for some time for the chemical to find its way into the wood. Check the label’s instructions on how long you’ll need to wait for it to dry.

Add some sawdust to the painted surface to thicken the chemical stripper. This will make it easy for you to remove the paint. Use a putty knife to start scrapping the stain. Be careful not to scrape the wood itself. If there’s still stain left, apply more chemical stripper to the area. Wait for it to dry, and scrape again. Use fine 180-grit sandpaper to smoothen the surface.

Stain the Wood

This step is optional, as many people prefer to retain the color of their mahogany doors. If you feel indifferent and would like to enhance the door’s color or conceal it, you should stain the wood.

You could use pigmented oil stains, as they are straightforward to apply. Like earlier stated, these stains will conceal the wood’s natural color unless you opt for penetrating oil stains. Penetrating oil stains doesn’t affect the wood’s color because it only penetrates the wood. It doesn’t rest on top like pigmented stains.

Use a paintbrush, preferably a natural bristle to apply the stain along the wood’s grain, starting from carved areas to the rails. Use a rag to wipe any excesses as you paint. After application, allow the stain to dry before using any sealer.

Apply a Sealer

Sealers add a protective film to your door, thereby resisting fading and wear caused by weather elements. When looking for a sealer, choose one with UV absorbers and tung oil.

Once you have your varnish, apply the first coat in quick and even strokes using the same natural bristle paintbrush. Wait for it to dry and sand lightly with extra-fine 220-grit sandpaper. Apply the second and third coats three coats and follow the same sanding process.

Should You Use Penetrating Oils Or a Varnish?

Most painters often raise this question when they are in doubt about what to do. The fact is using penetrating oils or a varnish depends on what you want, as both finishes have their pros and cons.

Penetrating oils dry into the wood when applied. That is during painting, the oil penetrates the wood. The good thing about using penetrating oils is that they don’t flake. However, they are not durable and fade away quickly. Worse still, they are susceptible to sun rays. Plus, they can become a breeding ground for mildew to grow if not maintained.

The varnish is more durable, and they form a protective film on the wood to prevent UV light and other weather elements from damaging the wood. The varnish is an effective finish and the best choice for coating exterior mahogany doors.

For an indoor piece of furniture, penetrating oils will work great. For exterior wood, using varnish is best due to its protective film coating.

You can use both penetrating oils and varnish together on the same wood if you want. However, this method is expensive and energy-consuming. You would need to reapply the penetrating oils periodically because they fade easily. This means stripping the varnish off, reapplying the oil, and then adding the varnish again.

Note that water-based finishes are not ideal for coating exterior mahogany doors except when combined with stains. It’s not ideal due to its moisture content. You should avoid buying them if you don’t plan on using stain products.

What is the best finish for Mahogany?

The best finish for mahogany is lacquer. Lacquer dries super-fast, incredibly durable, and doesn’t have the plastic feeling. You only need two coats of lacquer to permanently seal a mahogany door. Other great alternative finishes for mahogany doors that you can use include the varnish and shellac.

Is polyurethane OK for exterior use?

Polyurethanes are good for exterior use. It is one of the most durable finishes around and can be used on doors and other wood products successfully. To get polyurethane for exterior use, ensure you look for those with UV blockers.

How do your waterproof mahogany doors?

You can waterproof mahogany doors in three ways – by using Tung oil to create a protective finish, sealing the wood with polyurethane, varnish, or lacquer, and using a waterproof stain-sealant.

How long does Spar Urethane last outside?

Spar urethane lasts for up to 15 years if applied in the right proportion.

Is it better to stain or seal a deck?

Staining or sealing a deck depends on you. Staining a deck will give you the color you desire but can easily wear out, especially when used in high-traffic areas. We advise that you use a combination of stain and sealer for the best coating result.
