Various finish formulations can be used for exterior mahogany doors. Each formula carries different qualities that could enhance the sterling qualities of mahogany. So, if you’re a beginner, you might get confused as to which formulation to choose. It will be best to learn more about the most recommended finishes for mahogany doors to narrow down your options to the best options at hand. 

Types of Finish that Most Suitable for Exterior Mahogany Door

Mahogany is a reddish-brown and straight-grained timber. Several types of finishes suit this timber well. These finishes include lacquer, penetrating oil, polyurethane, and shellac. Below is a short description of each of these finishes:  

Lacquer

Your top choice for staining mahogany would be lacquer. Characterized by quick-drying, it also exhibits durability. It also doesn’t leave a plastic-like feel on the mahogany surface compared to varnish and shellac. You can apply two lacquer coats to give your mahogany door permanent sealing. 

Apply a light coat of lacquer to seal the pores of the wood. Then, apply a second lacquer coat to provide the wood with a semigloss finish. Lacquer is easy to use and apply, and within a few hours, you’ll get your job done.

Penetrating Oil

You can also use penetrating oil for your exterior mahogany door. It can protect your door from moisture with a single coat application of the penetrating oil. You can also add additional coats every six months or annually. 

You will find penetrating oils in different marketing names like tung oil, Danish oil, and linseed oil. Moreover, the penetrating oil may fail to render your mahogany door that glassy finish or sheen. Yet, you can also apply paste wax to create this glassy look on your mahogany door.

Polyurethane

You can apply polyurethane to your mahogany door. Polyurethane is a plastic compound that you can use restrictively on mahogany furniture exposed to moisture like the outside trim and exterior door. 

One downside of using polyurethane is its slow drying, resulting in an unsatisfying finish. Moreover, you’ll find it hard to clean your applicator after applying polyurethane. However, you can use thinner and other chemicals for cleanup.

Shellac

If you engage in a smaller project, you can use shellac on your mahogany door. You can easily brush this formulation and achieve excellent results. Shellac, of course, is a natural formulation created by insects and is eco-friendly. 

It produces a warm glow and renders an amber or orange color to your mahogany. It also dries quickly but not faster than lacquer. You can use the shellac for small projects like a small picture frame and small chests.
