How to Prime a Posca Marker Pen

To unleash the full potential of a Posca Marker Pen, it's essential to prime them correctly.

In this guide, we'll delve into the process of priming Posca marker pens to ensure smooth, consistent, and long-lasting results in your artistic endeavours.

Why Priming Posca Markers is Important

Priming a Posca marker pen is crucial for several reasons:

1) Ensures Even Flow

Priming helps to establish a consistent flow of paint from the marker tip, preventing streaks, skips, and uneven coverage.

2) Maximises Colour Intensity

Proper priming ensures that the marker delivers its full pigment intensity, allowing you to achieve vibrant and rich colours in your artwork.

3) Extends Marker Lifespan

By priming the marker correctly, you can prevent clogs and maintain the marker's performance over time, ultimately prolonging its lifespan.

Step-by-Step Guide to Priming Posca Marker Pens

Follow these simple steps to prime your Posca marker pen effectively:

1) Shake Well

Before priming or using a Posca marker pen, it's essential to shake it vigorously. This action helps to mix the paint thoroughly, ensuring a consistent colour and texture.

2) Depress the Tip

With the cap securely in place, depress the marker tip on a scrap piece of paper or cardboard.

Apply gentle pressure to release the paint and initiate the flow.

Continue pressing until you see a consistent flow of paint saturating the tip.

3) Test on Scrap Material

After priming, test the marker pen on a scrap surface to check the flow and colour intensity.

Adjust the pressure as needed to achieve the desired thickness of the line or coverage.

Tips for Priming Success

Here are some additional tips to enhance your priming experience with Posca marker pens:

1) Prime Regularly

If you haven't used a Posca marker pen for an extended period, or if you notice decreased flow, prime it again to refresh the paint and ensure smooth performance.

2) Clean the Tip

If you encounter any clogs or dried paint on the marker tip, gently wipe it with a damp cloth or paper towel to remove any debris and restore the flow.

3) Experiment with Surfaces

Posca marker pens are versatile and can be used on a variety of surfaces, including paper, cardboard, wood, metal, glass, and fabric.

Experiment with different surfaces to discover their full potential.

4) Store Horizontally

To maintain optimal performance, store your Posca uni marker pens horizontally when not in use.

This position helps to distribute the paint evenly within the marker, preventing clogs and ensuring consistent flow.


Priming a Posca marker pen is a simple yet essential step to unlock its full capabilities and unleash your creativity.
