Why finish your wood burned art at all?
A finish protects your burn from moisture, dirt, handling and (to a certain point) the sun, so it looks the way you made it for longer. It also changes how the piece looks and feels, sometimes beautifully and sometimes in ways you really did not want. So the real question is not "should I finish it?" but "which finish, for this piece?"
I wrote the first version of this post back in 2024. Since then, the Burn Club has grown into a whole room full of pyrographers who test, compare and discuss finishes all the time. So I went back through our conversations and rebuilt this guide around what our members actually use, what they love, and the mistakes they made so you don't have to. A huge thank you to everyone quoted here and sharing in the club!

A quick note on my own approach: I leave most of my personal pieces unfinished so I can re-burn them if they fade. BUT for client work and gifts, I usually go with mineral oil and beeswax. I usually burn deep so it takes my work longer than average to fade. I'm also just one burner, and there is no single right answer. That's why this guide covers the full range.
The one rule that applies to every finish: test it on the back of your piece or on a scrap of the same wood first (or keep reading to discover another testing method below). Every finish darkens wood a little, and some darken it a lot. Just take a look at this cherry wood below:
The quick answer
Before you finish: protect your shading
The most common heartbreak in our community is light shading that disappears the moment a finish goes on. The finish darkens the wood, the background catches up to your soft tones, and the contrast is gone. Here's how to avoid it.
1. Know that every finish darkens
Zona of BZFurFur summed it up perfectly:
"The truth really is: anything you put on the wood will 'darken' it even if just a little. Anything with 'oil' will darken it more than a 'poly' sealer." Zona
All species of wood will react to any finish. Some more than others, but even dark woods like walnut get a little darker, so just be mindful that you can lose your work by adding anything.
2. Preview the finish with rubbing alcohol
Thank you Zona of BZFurFur for sharing this amazing hack!! This is one of my favourite tricks from the club, and it costs almost nothing:
"If you lightly mist the piece with alcohol (I use 99%) it will darken the wood enough as if it was sealed and you can 'see' what it would look like sealed... before you actually seal it." Zona
The alcohol evaporates quickly and doesn't harm the wood, so if your shading looks too light under it, go back in and burn darker before you commit. No alcohol? A damp (not wet) microfiber cloth wiped lightly over the surface gives a similar preview. Try this before applying any other mediums!
See the full process in Burn Club+. Zona recorded her alcohol test step by step for our members, with before and afters of a burn that wasn't dark enough and one with the right amount of contrast. It's the clearest way to train your eye before you seal.

3. Burn a little darker than you think
If you know a piece is getting oil or resin, push your contrast further than looks right on raw wood. Deeper burns also hold up longer against fading.
4. Use an isolation coat for light woods and colour
An isolation coat is a clear layer that sits between the wood and your finish, so the finish can't soak in and darken it. I wrote a whole experiment on it here: Isolation Coat/Primer and Wood.
5. USE FIXATIF ON COLOURED PENCIL
Coloured pencil smudges if you breathe on it wrong. Julie, Argosy_girl, sprays hers with Krylon Workable Fixatif to set it. It stops the smudging, and because it’s “workable,” you can keep adding colour on top.
Her other tip: a white polymer eraser lifts smudges better than anything else she’s tried.
6. Let colour dry completely
Watercolour, ink and marker need to be fully dry before any finish touches them, or they bleed. Give it a full day if you can. Patience is key here…
7. Think before you seal
"There is no way to take the sealer off without damaging the burn. That's why I always think long and hard about using sealer." John of Circle 8 Pyrography
If there's any chance you'll want to add more burning later, wait. You can always finish later; you can't easily unfinish. Ask us in the Burn Club if you aren’t sure!
Oils: warm, rich, and the grain pops
Oils soak into the wood instead of sitting on top of it. They bring out the grain and give a warm rich vibe. Be careful though! They darken the wood more than any other finish, and most take days to cure. They will also need refinishing (especially if they are functional, like a cutting board, or in a sunny dry area).
Mineral oils
This is my own go to for client pieces and anything food related. I pair it with wax on top (my full method is in the wax section below).
Walrus Oil Cutting Board Oil and Howards Cutting Board Oil are the mineral oils I most often use.
Walrus Oil Furniture Butter is Zona of BZFurFur’s pick when she wants oil and wax in one: it "dries to the touch in 24 hrs, fully cured after 30 days. It's food safe once it's cured." Being an oil, it will darken the wood a bit.
Safety: oily rags can catch fire on their own. Rags soaked in Danish, tung or linseed oil heat up as they dry. Lay them flat outside to dry completely, or store them in a sealed metal can with water, before throwing them out. Please don't skip this step.
Danish oil: the club favourite (and the club regret)
Danish oil (natural finish) is the most used oil in the Burn Club. Chuck of The Burning Wood Chuck finishes nearly everything with it, including his whole Sara's Spoons series on red oak:
"I just finished it with Danish oil and it pops like crazy!" Chuck
But this one is also the finish members most often wish they hadn't used, almost always on a light wood with soft shading. Julie learned this on her very first Sunny Girl, burned on basswood. The oil turned it yellow and she lost a lot of detail:
"I won't be using danish oil on basswood ever again!" Julie
Another member found the practical side tough too: the smell lingers for ages, it takes days to cure, and getting rid of the oily rags safely is a hassle.
My take: Danish oil is gorgeous on oak, walnut, cherry and other woods with character, and on bold, high contrast burns. Always test, especially with any delicate shading. Do the alcohol test first, or use an isolation coat underneath.
Tung and linseed oil
Zona of BZFurFur is a Walrus Oil Polymerized Tung Oil fan. She uses it for her food safe items, like coasters, bowls, trays. She says it takes longer to dry and fully cure but she likes the finish best! Several members use tung and linseed side by side. One heads up from the club: thirsty wood can soak up far more oil than you expect, so buy more than you think you need. Another member switched to boiled linseed oil after polyurethane smudged her colour.
Tip: pure tung oil and "tung oil finish" are not the same thing. The second is usually a wiping varnish with a little tung in it. Both work, but they just behave differently.
Hemp oil
One member switched from polyurethane to hemp oil for indoor pieces after getting tired of all the setup poly needs. They use a no VOC, food safe hemp oil for everything that stays inside. It's so easy to apply! They still use poly for outdoor pieces though.
Waxes: soft glow, natural feel
Wax sits on the surface and gives a soft satin sheen and a lovely smooth feel. It darkens the wood less than oil, it's easy to apply, and it's easy to redo. Wax does wear off over time and needs reapplying, usually every year or so.
One member put it perfectly: she loves the satin look, the natural finish and the smooth, moisturized feel the wood has afterwards.
Another member uses a beeswax and carnauba blend. Carnauba is a harder wax, so it holds up a little longer than beeswax alone.
And John of Circle 8 Pyrography’s reminder: “Beeswax is great but you always have to reapply it to keep the look.”
Waxes our members use
Howards Wax-It-All was recommended to me by several people. It’s tough enough to handle a little warmth (like a bowl of warm soup on a large wooden board), and Howard’s says it even works on metal.
Minwax Paste Finishing Wax is Julie’s favourite because it doesn’t change the colour of basswood at all. More on how she applies it below.
Dorland's Wax Medium is made for artwork, not food. It’s a sealant, varnish and medium in one. The feedback I’ve heard from other people is that it won’t yellow over time and they really enjoy using it.
Zona's tip: wax over colour
Zona of BZFurFur uses Dorland's Wax Medium to seal watercolour on bookmarks, ornaments and small pieces. She applies a thin layer, melts it in gently with a heat gun, adds another thin layer, lets it sit overnight, then buffs.
My oil plus wax method
For client pieces and anything food related, I use mineral oil first, applying a very generous amount and leaving it to soak in for a few minutes. I wipe the excess, let it dry at least overnight, and then finish with wax, applying in little circular buffing motions. I like that the whole piece stays natural and could eventually go back into the earth without harm. The oil feeds the wood and the wax seals it in. I don’t love the blends (wax and oils in one), as I want my mineral oil to go really deep into the wood and then seal it off with wax.
Tip: tell your buyers to rewax
One of our members in Australia burns on invasive timbers and finishes everything with soft furniture wax. She encourages buyers to reapply it every 12 to 18 months. That's a great habit to build into your care card if you sell your work.
Julie's tip: less is more
Julie, Argosy_girl, loves Minwax Paste Wax on basswood. She’s used it on Old Man on the Mountain, Lake Winnisquam and two dog portraits. Her method: a very thin coat with cheesecloth, let it dry, buff by hand with a microfiber cloth, then repeat. But on one piece she put it on too heavy and couldn’t get an even sheen. Minwax's advice when she called: gently warm the whole surface with a hair dryer to level it out, let it dry thoroughly, then buff with a soft pad. Thin coats from the start save you the trouble (like with any finish: less is more).
Poly: polyurethane and polycrylic
Poly finishes form a clear protective film on top of the wood. They're the most popular choice in the Burn Club for indoor wall art, because they're durable, they darken the wood less than oil, and they come in every sheen from ultra flat to high gloss.
Polycrylic vs polyurethane: what's the difference?
Brands our members swear by
General Finishes High Performance (water based polyurethane) is Zona of BZFurFur's top pick for her fine art:
"It's pricey but hands down to me the best finish I've ever used. 2 thin coats, smooth, no streaks, barely there finish. Dries fast, no smell." Zona
She loves their satin version: "you can't even tell it's sealed! It looks and feels like it's bare wood."
Minwax Polycrylic, in both the spray and the brush on version, is a club favourite and John’s go to water based finish in satin. Chuck finishes with the semi gloss, Zona uses it for her non fine art pieces, and Amanda of Works of Fire seals her display pieces with satin polycrylic and keeps the matte spray on hand (the spray is convenient when you’ve got additional mediums that might smudge when you use a brush on version).
Julie’s method for her coloured pencil peonies and coneflowers: 2 coats of spray polycrylic first, then 2 coats of brushed water based polycrylic over top. She normally goes with satin.
Minwax Polycrylic Max is the newer one coat version. Amanda tested it on a large piece:
"I do like the polycrylic max! If using a brush didn't smear both the marker and colored pencils I would definitely use it to do one coat and be done." Amanda
Varathane Triple Thick (water based) is what John uses for indoor projects. It builds a thicker coat in fewer passes, with much less smell than oil based poly.
Fixing streaks and rough texture
Two complaints come up again and again: brush strokes, and a dry, rough feel. One member loved the look of poly but not how dry and rough it felt, even after 2 coats. I've found the spray version feels a little rough too.
The fixes, straight from the club:
Use the right brush. Zona of BZFurFur: "Try a brush specifically made for polycrylic. It's really soft and dense... Polycrylic likes to hold onto strokes." Brush one way, in long, light strokes, and don't go back over areas that have started to set.
Sand lightly between coats. This is what turns rough into smooth (full method in the step by step below).
Go thin. Two or three thin coats beat one thick one every time.
Outdoor pieces: spar urethane and spar varnish
For anything that lives outside (garden signs, plant stakes, cornhole boards, porch plaques), the club answer is clear: spar urethane or spar varnish. Spar finishes were made for boats. They stay a little flexible as the wood swells and shrinks, and most include UV protection to slow fading.
How many coats? Chuck recommends 5 to 6 coats for anything in direct sun. His pick is Varathane Ultimate Spar Urethane, the water based crystal clear satin spray. Julie uses Minwax Helmsman Spar Urethane and prefers the water based version. She used oil based on some plant signs and “it smells awful.” She puts 3 or 4 coats of spar varnish on her red cedar plant stakes, and they live outside from about April to November every year.
Outdoor tips from the club
Seal every side. Front, back, edges and especially end grain, which soaks up water like a sponge. Brandy Roels sprays the back and bark too, so the whole piece is balanced and covered.
Burn deeper. Chuck: "The deeper the burn the longer it'll take to fade since more wood material gets removed creating valleys that block sun exposure."
Sand between coats. Zona's outdoor routine: two coats, a light sand with a fine (220 or higher) sponge once dry, wipe off the dust, then another coat. Sanding between dry coats is the key.
Expect some fading anyway. Even with UV protection, the sun wins eventually. Plan to refresh outdoor pieces every year or two.
Choose a durable wood. Cedar handles the outdoors much better than basswood or pine.
Resin and glossy accents
Resin gives a thick, glassy, juicy shine that nothing else can. In our community it's used far more for accents (eyes, gems, flower centres, keychains) than as a full finish, because covering a whole piece is messy and expensive.
Full pour epoxy resin
I've poured resin a few times, and here's what I learned:
It darkens the wood, a lot on many species, especially cherry. Use an isolation coat first if you have light shading.
Prep is everything. Set up a level surface, cover the piece with a cardboard box while it cures so dust doesn't settle in it, put something underneath to catch drips, and wear gloves.
Pop bubbles with heat. A lighter works on small pieces; a torch is faster on large ones. Don’t go too hot though, otherwise you can burn it.
Keep it indoors and out of the sun. Some resins can yellow and cloud with UV and moisture.
Resin is not food safe, so skip it on anything that touches food.
I used ArtResin and would buy it again, partly because their customer service walked me through getting a frosted look step by step.
John of Circle 8 Pyrography’s take: “I would only use resin if I used it for a table.” Full pours are a big commitment, so save them for pieces that really need a hard, glassy top.
UV resin for small details
UV resin cures in minutes under a UV lamp, so it's perfect for tiny details. I got the Let’s Resin Kit which comes with a little flashlight style UV light and I used it to give my mushroom characters glassy eyes. It seriously blew my mind how realistic they looked. Zona uses it on keychains and has two big tips: seal the wood first, and use a doming (high viscosity) resin because it's thicker and won't run off the edges. Her favourite brand is Let's Resin as well!
3D crystal lacquer
John uses 3D Crystal Lacquer over Deco Foil (learn more about metallics on wood here) to make little raised, glassy accents: "I think it gives more dimension to the foil." He's also used it on flower centres to make them look puffy. It's a simpler, cleaner option than resin for small spots.
Quick hack: in a pinch, clear nail polish adds a glossy dot of shine (thank you, John of Circle 8 Pyrography, for sharing this hack). I tried it on eyes before I got UV resin, and it wasn't terrible! It gave me a shine, but if you want it to be more impactful, try the UV resin or 3D crystal lacquer. They are both VERY satisfying to look at and pretty simple to apply!
Step by step: how to finish your piece
This works for almost any finish. Where oil, wax and poly differ, I've noted it.
Clean up the surface. Erase any leftover transfer lines and brush away loose char with a soft brush (I like to use a microfiber cloth and then a clean toothbrush). Zona gently cleans stubborn spots and burn lines with the scrubby side of a dollar store sponge and a soft toothbrush, then lets it dry overnight.
Sand very lightly. Use a fine sanding sponge (around 320 grit), always with the grain, just enough to knock down raised fibres. Go gently over your burn so you don't lighten it.
Remove every bit of dust. A microfiber or tack cloth works well. Dust trapped under a finish shows forever. At this point, I use the microfiber cloth and then the toothbrush again!
Preview the darkening. Do the alcohol mist test from earlier. Burn darker now if you need to.
Got colour? Use a spray finish. Zona's rule: if she used any medium at all (paint, marker, chalk, ink), she always sprays at least 2 layers of sealant before anything gets brushed on. Light, even passes from about 30 cm (12 inches) away.
Apply your finish thin.
Poly: thin coats with a soft brush, in one direction, without overworking.
Oil: wipe or brush it on, let it soak for 15 minutes or so, then wipe off all the excess.
Wax: a thin layer worked in with a soft cloth. I press it into the wood, then take off as much excess as possible before buffing.
Sand lightly between coats (poly and spar). Once a coat is completely dry, give it a very light pass with a fine sanding sponge or 320 to 400 grit paper. As John says, "that's a LIGHT sanding just to take off the dust that's in the top coat!" Wipe the dust off before the next coat.
Add your final coat. Two to three thin coats is plenty for most indoor art. Outdoor pieces need more (see the outdoor section).
Buff. For wax and oil, buff to the sheen you like. Zona swears by old jeans: they have just enough scrub to buff without leaving scratches.
Finish the back and edges too. Sealing all sides helps the piece move evenly with humidity and keeps it from warping.
Let it cure fully. Dry to the touch is not cured. Water based poly cures in a few days; oils can take days to weeks (Walrus Furniture Butter takes 30 days). Oil based finishes cure faster somewhere warm.
Ventilation matters. Oil based products have strong fumes. Zona does her oil based sealing outside, and added an air purifier with a filter made for chemical fumes for the days she can't. Wear a mask rated for vapours if you're finishing indoors.
Can you burn over wood that's already finished?
Short answer: please don't. Always burn on raw, untreated wood, then finish after. This question comes up in the club all the time, usually with a commission: a surfboard already oiled, a charcuterie board, a guitar, an heirloom hope chest.
Burning through a finish releases fumes from the finish itself, and those are not something you want to breathe. Even if you try to sand it all off, you risk the substance being deep in the wood and not getting down to a place that is free of any chemicals.
It can also gunk up your tools, and change the feel of the finish making it feel sticky or tacky forever.
Caring for and refinishing your piece
Oil and wax: easy to refresh. Wipe the piece clean, apply a thin new coat, buff. Plan on every 12 to 18 months for wax, or whenever the wood looks dry.
Poly and spar: lightly scuff sand the surface, wipe off the dust, and add a fresh coat. Indoor pieces rarely need it; outdoor pieces every year or two.
Everything: keep it out of direct sunlight and away from moisture. No finish fully stops it from fading.

Frequently asked questions
-
No. I leave most of my personal pieces raw so I can re-burn them if they fade. Some members ask the buyer which finish they'd like. For gifts and anything handled often, a finish is a good idea.
-
It slows it, but doesn't stop it. Even with a UV protective varnish, burns can fade in sunlight. Burning deeper and keeping pieces out of direct sun help the most.
-
Satin is the club favourite for wall art. Matte looks closest to raw wood. Gloss shows every brush stroke and bump, so it's best on very smooth pieces.
-
Only products labelled food safe once cured, like food safe mineral oil, beeswax, and specified cutting board products, and some hemp oils. Never use polyurethane, polycrylic or resin on boards, spoons or utensils.
-
This one is a commone question! I don’t recommend it. It’s made for crafts and decoupage, not fine art, and it clouds with humidity. It clouded on my bark edges, so now I use Titebond Translucent Wood Glue there instead.
