The answer to this question depends on the surface you are using the Posca pens on and the conditions it will be exposed to.
Are Posca Pens Waterproof?
Posca pens are water-based, which means they can be easily washed off with water when wet. However, once they dry, they become water-resistant or even waterproof, depending on the surface.
Posca pens are ideal for use on non-porous surfaces such as glass, metal, and plastic, where they are water-resistant and can withstand some exposure to moisture.
On the other hand, using Posca pens on porous surfaces such as paper or fabric may result in the ink bleeding or fading when exposed to water or washing.
Posca pens are known for their versatility and ability to work on a variety of surfaces.
Let’s take a closer look.
Are Posca Pens Waterproof on Glass and Porcelain?
Posca pens are waterproof on glass and porcelain surfaces. Once the ink dries, it becomes resistant to water and can withstand light washing.
However, it’s important to note that prolonged exposure to water or heavy scrubbing may cause the ink to fade or come off.
Are Posca Pens Waterproof on Fabric?
Posca pens are not completely waterproof on fabric surfaces.
While the ink is water-resistant, it may still bleed or fade when exposed to water or washing. To make Posca pens more resistant to water on fabric, it’s recommended to heat-set the ink by ironing the fabric on a low heat setting for a few minutes.

Are Posca Pens Water Resistant?
Posca pens are water-resistant, but not completely waterproof. Also, they can sometimes become watery – we have an article here with solutions if your Posca pens are too watery.
The ink is formulated to resist water, but it may still fade or come off with prolonged exposure to water or heavy scrubbing.
Testing Posca Pens for Water Resistance
If you’re unsure about the water resistance of your Posca pens, you can test them by drawing on a scrap piece of paper or fabric and then running it under water or rubbing it with a damp cloth.
This will give you an idea of how well the ink will hold up to water.
How to Make Posca Pens More Waterproof
To make Posca pens more waterproof, you can try heat-setting the ink on fabric surfaces, as mentioned earlier.
You can also try using a fixative spray on other surfaces, such as paper or wood, to help seal the ink and make it more resistant to water.
However, it’s important to note that using a fixative spray may alter the appearance of the ink or cause it to become less opaque.
Are Posca pens waterproof or washable?
Let’s start with the second part of that question.
Are Posca pens washable?
