Posca markers are acrylic paint-based marker pens that can be used on all sorts of surfaces and for a variety of projects. The paint is non-toxic, opaque, lightfast, water-resistant when dry and doesn’t bleed through paper. They can be used to create bright, vibrant designs on almost anything –  paper, cardboard, wood, fabric, plastic, glass, metal and even surfboards! Poscas come in a wonderful range of colours and nib sizes from brush tip to fineliner to a chunky chisel tip so you’re sure to find one that’s perfect for you! There are so many applications that these pens can be used for, so here are some guidelines to make sure you get the best of your Posca markers:

Always make sure your surface is clean, dry and free of dust before you begin. If your marker is brand new you will need to shake it very well to ensure the paint is well mixed. You’ll want to hear the ball inside the paint cartridge shaking around as this helps to mix up the paint (NB it’s a good idea to always shake your Posca markers before using them). If you have a Posca with a bullet tip you will need to press your nib in a few times to get the paint to start flowing. This is not the case with the extra fine tip (PC-1MR) fineliner tip which does not need to be pumped or the brush tip marker (which needs to be pumped using the back end of the pen). The tips can be rinsed with water and some of the tips are reversible – simply pull out the nib, flip it around and pop it back in! It is important to always place the cap back on tightly after use to ensure your pens don’t dry out.

If you are working onto cardboard or paper there is no need to fix the marker in, as the paint will be absorbed into the paper making it permanent. There are other surfaces, however, where the Posca marker paint will need to be fixed in order to make it last:

  • Terracotta – bake in the oven at 220°C for 45 minutes. Once cooled, spray with a clear varnish.
  • Wood – spray with a clear varnish
  • Metal – spray with a clear varnish
  • Fabric/ textile – iron on the reverse
  • Porcelain –  bake in the oven at 160°C for 45 minutes. Once cooled, spray with a clear varnish.
  • Plastic – spray with a clear varnish
  • Glass – bake in the oven at 160°C for 45 minutes. Once cooled, spray with a clear varnish. Poscas are also excellent to use on glass if you’re wanting to create a non-permanent design such as a sign on a window (we have a blog post about just that). The paint can easily be removed as the surface is non-porous.

* Please note that objects sprayed with a clear varnish are not necessarily safe to eat or drink out of. It is recommended that these items should be used for decorative purposes only.

Last but not least, you can use your Posca to sign your name on your artwork (except for on oils)! View the range now on our online store.

    1. Hi Nicole

      Posca pens are water based markers and we would not recommend using them on top of oil paintings. You can treat them the same way as you would acrylics in oil painting where you use them as a base and work on top with oils.

      I hope this information helps 🙂

  6. We are full time artists, my husband and I and we work in Posca pens. We would like to buy sets, is that available please?

  7. Hello
    Can these markers be used on polymer clay? And they won’t fade, bleed or de-colour?

    1. Hi Maxine

      They are waterbased paint markers and will definitely stick to a cured polymer creation.

      They dry waterproof and should not fade or diss-colour. However, we would recommend adding a layer of varnish over your Posca work.
      The varnish should help protect against scuffing , chipping and flaking of your designs. 🙂

  8. Hi,

    I want to paint some Easter eggs, I spray paint the eggs first and then paint on top of them and I was wondering which markers would be best to use? Posca or the Pilot Pintor markers?

    1. Hi Anika

      Both the Pintor and Posca are water-based paint markers and will work in much the same way. So either option should be fine. 🙂

  9. Hi there,
    My daughter would like some medium Posca Paint Pens with all the colors but I am concerned about the price so can you please get back to me on that
