Light Green Fine 3M Posca Marker are acrylic ink markers that can be used to paint on many different surfaces such as wood, metals, plastic even glass. Just make sure to shake the pens to mix the paint before each use. It is recommended to seal artwork with a varnish. You can use spray-on or paint-on acrylic varnishes.
Posca paint will dry waterproof and permanent but some surfaces will need heat-setting and sealing to make the Posca artwork more permanent.
For ceramics and glass, heat-fix by oven baking at 160c for 45mins. Pottery will need a higher temp, approx 200c+ for 45 minutes. Times will vary but these have worked for us.
To make fabrics, like t-shirts, washable dry-iron on the reverse side to the Posca artwork. This will permanently fix it to the fibres. Some fabrics will work better than others so a trial is recommended. Canvas shoes can just be sealed with spray varnish to avoid scuffing.
