Don’t Skip the Finish: How to Make Your Forged Work Last
When the hammering stops and the fire dies down, a blacksmith’s job still isn’t finished. The final step—choosing a finish—can be just as important as forging the piece itself. A good finish protects your work from rust, adds character, and enhances the craftsmanship you've put into every blow.
In this post, we’ll explore four popular finishing methods used by blacksmiths: beeswax, oils, paint, and patinas. Each brings its own benefits, challenges, and personality to your work. Whether you’re after something traditional, durable, or artistic, there’s a finish to match your goals.
Beeswax Finish
Beeswax is one of the most time-honoured finishes in blacksmithing. It’s simple, effective, and has been used for centuries.
Pros:
Natural and non-toxic.
Brings out a soft, dark sheen on the metal.
Easy to apply while the piece is still warm.
Cons:
Not very weatherproof—can wear off outdoors.
Needs periodic reapplication to maintain appearance.
Best For:
Indoor items like wall hooks, fireplace tools, or decorative pieces that won’t see a lot of moisture.
Application Tips:
Heat your piece to around 200°F (not red-hot).
Rub the beeswax onto the metal, then wipe and buff as it cools.
Optionally, mix in a little boiled linseed oil for a glossier finish.
Oils
Oils like boiled linseed oil, tung oil, or mineral oil offer a more penetrative and protective option—especially for tools and objects handled frequently.
Pros:
Deepens the steel’s natural colour.
Provides some rust resistance.
Easy to apply and reapply.
Cons:
Some oils can feel sticky if not wiped properly.
Regular maintenance needed to retain protection.
Best For:
Hand tools, knives, or any forged object that will be handled or stored indoors.
Application Tips:
Heat the metal gently—warm to the touch, not too hot.
Rub on a light coat of oil, let it soak, then wipe off excess.
Repeat every few months for best results.
Paint
Paint isn’t just for cars and walls—it’s a tried-and-true method for protecting forged metal, especially outdoors.
Pros:
Long-lasting, durable protection.
Available in any color or finish you can imagine.
Hides surface imperfections.
Cons:
Can obscure the texture of your forging work.
May flake or chip if not properly prepped.
Best For:
Gates, fences, outdoor furniture, signage—anything that will face the elements.
Application Tips:
Clean your metal thoroughly (wire brush, degreaser).
Apply a metal primer before your top coat.
For extra durability, finish with a clear sealant.
Patinas
If you’re looking to give your work an aged or artistic touch, chemical and natural patinas offer limitless possibilities.
Pros:
Unique, character-rich finishes.
Range of colors and effects—from blue-black to rusty red to verdigris green.
Adds artistic and antique flair.
Cons:
Results can vary depending on metal and conditions.
Often needs sealing to preserve the look.
Best For:
Sculptures, artistic commissions, display pieces—where appearance takes center stage.
Application Tips:
Use a clean, grease-free surface.
Apply patina chemicals carefully and allow them to react naturally.
Neutralize the chemical after the desired effect, then seal with wax or clear lacquer.
Bonus: Clear Coats & Sealants
Whether you use wax, oil, or patina, a clear sealant like polyurethane or lacquer can dramatically extend the life of your finish—especially for items exposed to moisture or heavy use.
Just keep in mind: Some clear coats can change the colour of your metal, especially over time.
Conclusion
Choosing the right finish is part of the artistry of blacksmithing. It's about more than just protection—it's about honoring the piece you've made, and presenting it the way it deserves.
Experiment on scrap. Try new combinations. Find what works best for your forge, your climate, and your style.
