How Does POSCA Paint Work on Different Surfaces?
POSCA markers use water-based pigment paint that is designed to provide strong, opaque coverage. The finish and permanence depend on the surface being painted.
| Surface | What to know |
|---|---|
| Paper, card and wood | Ideal for drawing, illustration, lettering and graphic work. |
| Canvas and fabrics | Suitable for artwork on canvas. For fabrics fix artwork by ironing the reverse side. Use paper to protect ironing board. |
| Stone and unglazed ceramics | For rock painting and decorative projects. |
| Glass and glazed ceramics | Suitable for temporary designs; the paint can generally be removed from smooth surfaces. |
| Metal and plastic | Useful for decoration and customisation. Test first, as the finish and durability depend on the material. |
For artwork intended to last, particularly on objects handled frequently or displayed outdoors, check the surface preparation and appropriate sealing requirements before use.
How to Use Your POSCA PC-5M Marker
- Shake the marker well with the cap firmly attached to mix the paint. You’ll hear the ball bearing inside.
- Remove the cap and press the nib in gently, several times. Soon the paint will appear and begin to flow into the nib.
- Once the nib is filled with colour test the flow on scrap paper. Once the pen creates a solid line with a single stroke, it is ready to use.
- Allow the paint to dry between layers when building up opaque coverage.
- Replace the cap securely after use. Don’t forget to shake the marker beofre each use.
