You have dozens, maybe hundreds, of ways to finish mahogany for your woodworking projects. That’s part of the beauty of the wood; you can apply nearly any finish to it and it’ll look wonderful. So there’s no way to make a definitive declaration about the best finish for mahogany. But I can pass you a few tips, ideas, and tried-and-true techniques that have served woodworkers for many years.
Absorb these three techniques, you might find them useful for your woodworking projects. The video above demonstrates how to fill grain, stain and dye to achieve the following looks and colors in mahogany.
1. How to Make a Deep Red Antique Mahogany Finish Using Dye, Stain, and Filler
Of the three process we’ll show you here, this one is the most sophisticated, but it also has the most interesting result of the three. While there are a few steps, it’s a straightforward process that’s not hard to pull off. Even though I’m going to list the exact brands and products I used to create this finish, they’re less important than understanding the process. Other brands will work just fine, too. In short: dye the wood to make it the overall color you want, seal it, fill the grain with something dark (aside from the filler I used, there are several other options too), apply a protective finish on top and polish it.
- Solar Lux aniline dye, medium brown walnut color (it dries with a maroon red color)
- Old Masters Woodgrain filler
- Zar oil stain, Early American color
- Denatured alcohol
- Zinsser SealCoat
- Spray lacquer
- Prepare the wood surface as you normally would by sanding to 180 or 220 grit
- Prepare the dye by diluting it by 50% with denatured alcohol in a mixing container. Apply the dye, either with a pad or by spraying
- Let it dry, then apply another coat of dye. Repeat until you’re happy with the color
- Apply a coat of Zinsser Sealcoat after the dye is dry. Work quickly and do not let it drip or pool.
- After it has dried, you may lightly and carefully sand the sealer if it developed nibs or bumps. Be cautious not to sand through the dye.
- Mix Old Masters Woodgrain Filler with a dark brown oil stain. In this example that’s Zar Early American. Use a 2:1 ratio, 2 parts filler to one part stain.
- Apply this tinted Woodgrain Filler with a rag, brush, or scraper to work it into the pores of the wood. Follow directions on the can. Let it dry for about 5 minutes, the wipe it off moving across the grain.
- Allow the filler to dry about 4 hours. Do another application if the grain is not filled to your satisfaction.
- Apply the topcoat of choice. The sample above is finished off with another 3 coats of Zinsser SealCoat, sanded between each one with 220 grit. And then it’s sprayed with 3 coats of lacquer, also sanded between each coat.
- Buff and polish when the top coat is ready.
2. Staining Mahogany The Easy Way
Coloring mahogany doesn’t need to be as involved as that first process. You’re allowed to just open a can of wood stain and put it on the wood. The results, of course, are far less dramatic and less nuanced, but they’ll still look nice. There are a lot of kinds of oil stains to choose from, but basic penetrating oil stains seem to bring the nicest results from the bunch. Opinion, of course. But the pigment builds up in the pores, darkening them more than the surface wood which highlights the character in the wood.
Not all oil stains are engineered the same way. Gel stain, for example, is most often suited for creating a wood grain appearance on fiberglass doors. That’s why if you were to get up close to the stained piece of mahogany on the right you’d notice that the color appears to be almost like a translucent layer of color riding on top of the wood rather than getting into it. The gel stain has muddied the grain of that piece of mahogany. Gel stain has its place — on a piece of raw mahogany is, arguably, not it.
Genuine mahogany also accepts water based stains just fine. As usual, raise the grain and sand it back before applying the water based stain. If you do want to use a water based stain, I suggest filling the grain with a darker water based filler first. Perhaps Timbermate’s walnut colored filler.
After staining mahogany (and after it dries!), protect it with your preferred top coat like varnish, shellac, lacquer or polyurethane.

3. Fill the grain to get a perfectly smooth finish
Your mahogany woodworking project will benefit greatly if you fill the grain first, and you’ll notice the difference between a finish with the grain filled and one without the grain filled. So how do you do it? There is more than one way to skin this cat, so here are two.
1. Woodgrain Filler or another paste filler
We already brought up Old Masters Woodgrain Filler in the first process above. So that’s one product you can use, and it’s easy to work with. The trick with it is that you’re supposed to tint it with an oil based stain because out of the can it’s an off white or cream color. So you tint it, apply it, wipe it off, and once it dries sand it smooth. The sanding could be optional if you wipe it down well enough and you approve of the color that it leaves. Naturally, the stain you tinted the filler with will color your wood — the sanding will clear it up though. If you still want to stain your mahogany a darker color, you can do so. So you get the benefit of darkened pores, filled pores, and the choice of keeping your mahogany its natural color or staining it.
Another way to keep the stain in the filler from darkening your mahogany is to put down a washcoat (a coat of sealer) before the filler.
2. Timbermate, or another water based wood filler
The benefits of a water based wood filler is that it dries much faster and clean up is much simpler than the oil based filler above. You also don’t have to tint it, as it frequently is available in numerous colors. The brand Timbermate offers a mahogany color filler, which is what I’ve used in the sample in the picture above. A darker filler might prove to be a little more interesting, darkening the pores more, but the point is that the filler helps you achieve a glassy smooth finish quickly.
