Wood –works best when used on sealed surfaces and provided with a couple of thin coats of a varnish spray. I have had reports that Posca scratches off in some situations, so it would need to be varnished. I have been told that some brush-on varnishes smear it a bit. So the first coat of varnish should be a spray, to set it. Then apply a couple more thin coats of a hard, outdoor, UV protecting varnish like Golden MSA. Posca pens are among the best things to ever happen to illustrative and creative minds. And if you are wondering what is so special about them, well, they are vivid, opaque, smooth, lightfast, and super versatile paint pens. Of course, no product is going to be the best option for all consumers. Nonetheless, these Posca paint pens are certainly a worthwhile investment if you want a versatile paint marker that can help you add some finer details to your artwork or spice up your scrapbooking skills. I strongly believe that any person who’s interested in exploring their artistic side is likely to benefit from purchasing these Posca paint markers.
The beauty surrounding these markers is that these items offer exceptional adherence to almost all surfaces while providing very little show-through or bleeding. Here are the surfaces you can use these Uni Posca paint pens on: These water-based acrylic paint pens mark literally any surface: glass, metal, select plastics, wood, cardboard, concrete, and ceramics. But if you got them to use on paper, you must be careful of your choice because some papers are flimsy and don’t do well with wet media. The texture of the paper is fundamental when choosing paper for Posca pens. Smooth surfaces produce best results with Posca pens hence go for coated paper. Avoid super absorbent paper that will bleed and also soak the paint instantly. If the paper is not coated, at least it should be fine-grained. Visibly coarse paper may begin to pill when you go over it with the wet pens. Binding and Cover So, what is the best paper for Posca pens? The best paper for Posca pens is high-quality, sturdy, smooth-textured, and bleed-proof paper. Paper like Bristol and mixed media paper can handle the wetness of paint and rubbing of the nib without wrinkling or tearing.A smooth coat is critical, especially if you intend to blend and layer the paint. The coating minimizes the paint absorption speed, so you have a long window period to work the paint, mix colors and create smooth gradients before it dries.
As with most painting projects the preparation of the surface is the most important part for creating a long-lasting object. It should be clean and free of oil or wax and if it is non-porous it will need to be roughed up a bit with sandpaper to create a ‘key’ for the paint to latch onto. Skipping the proper steps of preparation and jumping to the fun part of applying the colour causes problems for artists, craftspeople and house painters.Paper– offers permanent results for all types of paper and cardboard. This includes photos, tracing paper, and correlated cardboard. The ink in these pens doesn’t bleed through the paper. Isolation coats are usually used to protect paintings where the varnish may be removed later (if it has become dirty; then the varnish can be removed without disturbing the painting underneath). I wonder how likely it is that you will need to remove the layer of varnish at a later date? If it is likely then to be honest I would use an acrylic based layer of colour rather than a water-based dye, work with the Poscas on top, then apply a 2:1 Soft Gel Gloss to water mix as an isolation coat, and then a layer of your final protective coat, which needs to be removable and hard-wearing. I stop short of recommending any specific product because I think you need to seek the advice of a expert in guitar-making who will know what is most suitable for your needs. The skull should be much easier since bone is porous unless it has been waxed or varnished. If it is very dry and porous you might want to apply a clear primer first so the paint doesn’t soak in and sit under the surface. Then paint with the posca and when it is dry varnish as above. If you wish the skull to not be shiny then for the last coat of varnish you can use a matt varnish. The first coats should be gloss because a build-up of the matt varnish will usually be cloudy, but one final coat of matt is fine. Glass – semi-permanent for window displays (draw on the inside of the window and remove by scruubbing off with window cleaner), on glass items you can fit in an oven they are permanent (for light use) after baked.
After you have seen this ink filled in the tip of the pen, you can start applying it to whatever surface you would like. With that being said, you must remember that this ink gets hard when it dries when applied to a porous surface. However, the ink can be wiped away with a sponge, wash cloth, or water if it’s still wet. You should account for this if you make a mistake and the ink is still wet. If you’ve invested in Posca pens, chances are, the ultimate goal is professional results, and with that is the expectation of permanence. Therefore, it would greatly help if the paper were acid-free for archival purposes. These paint markers are available in a range of sizes, which means that each item has a different period. Nonetheless, each paint marker is equipped with a high-quality nib that makes the pen long-lasting while stopping the pen from running or leaking. Yes, this product contains non-toxic water-based paint, which is acid-free and is called Opaque. It’s also known for being light-fast, odorless, xylene-free, waterproof, and lead-free when dry. Usually isolation coats are for acrylic based paintings, and not used for layers of water-based colour. I wonder why you want to apply an isolation layer between your layer of dye and the posca pen work – If I understand your intentions correctly I think you can go straight ahead and work with the Poscas over the top of the colour without an isolation coat in-between.
The Bottomline
The paint included in these markers is water-soluble, which means that the ink can be diluted to create an amazing gradient effect. With that being said, this process can take time to ensure it dries properly. One handy tip that you can do is use a brush that’s been soaked in water before starting any project. After applying the paint from the marker, trace over it with the set paintbrush. You should do this before the paint from these markers dry. Mix-Up the Markers
