Are Posca markers permanent?
Although Posca paint will stick to almost anything, this doesn’t mean it will become permanent. This will depend on several factors, but primarily on the texture and composition of each surface.
Below is a rundown of the materials most commonly used by Posca artists to give you an idea of what to expect. On most materials, you make Posca markers permanent with a simple water-based varnish.
1. Paper/cardstock
Paper and cardstock are among the most popular materials used with Posca pens for creative hobbies such as scrapbooking, fashion illustration, card-making, and more.
This medium allows you to play with various drawing techniques and effects and create colorful, opaque lines, whether bold or delicate.
Posca paint has some of the best results on paper and cardstock, leaving permanent, long-lasting ink on the page and rarely any bleeding. Unless your art is subject to extreme sunlight or humidity, you won’t have to worry about your work staying intact. If it is, hit it with a UV-resistant varnish.
2. Canvas
Canvas and Posca markers are a match made in heaven. Like paper, Posca paint adheres organically to canvas and ensures permanent outcomes every time.
However, remember not to exhibit your projects in areas prone to humidity or intense heat, as this is likely to affect the integrity of your work.
That said, while Posca paint will stick permanently on canvas, I advise giving your work some extra TLC and spraying some water-based varnish to enhance longevity.
3. Wood
Posca markers are very sought-after for wood-centered ventures and suitable for indoors and outdoors. So, are Posca markers permanent on wood?
Posca paint works well on rough and sanded wood, but how long it lasts depends on these surfaces’ porosity. You’ll also need to consider the specific type of wood used.
I recommend applying a few coats of water-based varnish on your projects after painting them to protect them from UV, dust, and humidity.
4. Fabric/textile
Personalizing apparel and accessories is a great way to wear your personality on your sleeve (literally).
And Posca paint markers will do the trick — or at least for a while. Unfortunately, after a few washes, Posca paint will begin to fade. How long this takes will depend on the textiles you use.
To make it last longer, use an iron to apply heat to painted areas (no steam), followed by sealing pigments with a skin-safe varnish. Also, hand-wash your pieces inside out vs. washing machine.
5. Ceramic
Posca markers are really fun to use on ceramic, although a challenging medium to work with regarding permanence.
Generally, for varnished ceramics like glazed porcelain (mugs, flower vases, etc.), all it takes is lukewarm water, a moist cloth, and a little scrub to remove paint.
On the other hand, Posca paint is more permanent on ceramics like terracotta (tile, brick, etc.). In either case, you can always spray water-based varnish to boost durability.
6. Metal
Posca markers are often used on aluminum and iron. However, for permanence, I typically recommend other surface types.
Posca paint adheres effectively to industrial, porous metals but has difficulty remaining on smoother metals like those found in water bottles or keychains.
For this particular material, I especially advise cleaning and priming surfaces before applying Posca paint. To protect your work from abrasion, UV damage, and moisture, spray varnish on your project once it’s finished.
7. Rock
Rock painting with Posca markers is super soothing and allows you to experiment with lots of designs and colors. It’s a great medium to let imagination take the lead!
Rocks are somewhat unpredictable to work on due to their different textures or natural tones, so you may have to do a bit of layering to make colors pop.
As long as your rocks aren’t in contact with water or direct sunlight, paint will remain vibrant for a long time. Want to play it safe? Add up to four coats of water-based varnish to completed projects.
8. Glass
The upside of using Posca markers on glass is that paint is easy to remove, which allows you to keep reinventing designs on items you love.
The downside? It only takes a wet cloth or acetone and a little scrubbing to wipe Posca paint off. On the other hand, you can make Posca paint last on glass permanently by curing it in the oven.
Note that there are specific steps and requirements to go about this process. Therefore, I recommend this for experienced DIYers focused on honing their glass crafting skills.
9. Plastic
I’m not particularly fond of crafting with plastic, but if this is a medium you’re interested in exploring, know that Posca paint will adhere well to plastic and can become permanent with the proper care.
Without any further steps, Posca paint can be washed off from plastic with lukewarm water and a cloth, but it will mostly come off due to friction.
For example, if you draw on your cellphone case and carry it in your handbag or your pockets daily, the paint will eventually wear out. To make items last longer, apply varnish on your plastic creations to seal the paint.
