Can you spray paint plaster?
I'm doing sculpture out of plaster and i want to give it a metallic look. Can I just spray it or do I need to put something over it like PVA (because plaster is porous? Also to give it a metallic shine do I need to add a finish or will the spray paint be enough?
What paint should you use on plaster of Paris?
It depends entirely on what effect you are trying to achieve. If you paint on plaster that is still moist with tempera (artist’s tempera, not school paint), the plaster and paint will form a bond as they dry, like a fresco. You can use powdered pigments and soft wax to create a luminescent glowing color that seems to float on the surface of the plaster, or you can coat the plaster with gesso, and then use oil paint, acrylic, latex or any other material you wish, including metallic paint or metal leaf. It’s important to seal the plaster with gesso, because otherwise it is very absorbent, and t will be difficult to get good coverage without using several layers of paint. If you don’t care about the archival quality of the finished work, you can just use spray paint, paint sticks, water soluble or oil based crayons, or any coloring medium you like, but you should be aware that most of these less expensive media are not as permanent as artists’ colors, whatever the medium.
Bronze finish on plaster surfaces?
Here you go I found this on the net for you.... http://users.lmi.net/~drewid/A%20bronze%20look%20for%20plaster.html Q: I know there is a process to make plaster objects look like bronze. How is it done? A: The first thing is to prime the plaster item with shellac, first using a light coat cut with an equal part of denatured alcohol, letting that dry, then applying a full-strength coat. This seals the plaster and prevents it from sucking the volatile components out of the subsequent layers of paint, interfering with their film formation. After the shellac is dry, put on an oil or lacquer based gold paint, either by brushing or spraying. There are various types of gold paint available, which vary widely in their effects. Then cover the whole thing with a dark brown colored oil paint, and wipe it off the high spots while it is still wet. This process can be repeated several times, until the "antiquing" seems about right. Optionally, one can go for a "verdigris" effect, using shades of green oil paint over the brown once the brown has dried, rubbing it off the high spots just a little. Paste wax can be used over the surface for protection and glossiness. There are other versions of this process which depend on coatings containing copper or bronze powder. These can be treated with chemicals to obtain an actual patina, either greens or shades of brown. Another approach is to add atomized copper or brass to certain formulations of gypsum cement, in sufficient concentration to make the surface somewhat metallic. This can then be patinated in a similar way. Or, alternatively, one can paint the plaster item with a conductive solution, then electroplate it with copper. This can then be treated with chemicals to achieve various color effects. Andrew Werby - United Artworks
What is the best way to seal plaster of paris before painting?
Acrylic matte medium will do the trick, especially if you're going to paint on top with acrylics. You won't be able to paint acrylic on top of shellac or anything else oil- or solvent-based. You need something that will dry quickly before the plaster absorbs it. You must be sure the plaster is completely dry first - this could be why paint would flake off others' work - moisture trapped under the paint/sealer will cause it to bubble and peel. If the plaster feels cold, it's not dry. Please test anything you use on the bottom first, that will reduce the heartache factor.
What are the ways to paint a plaster sculpture?
Plaster is absolutely the most absorbent material I can think of. For this reason most paint will work in that it soaks in.If you have a completely matte white surface and you change the color and sheen, you might be taking something that has a fascinating surface and turning into a cheap looking plastic. It's a problem to be solved by a real artist even if the surface is all one color.At the PA Academy of Fine Art, the oldest art school and museum in America, there are many casts of famous sculptures. We drew then as a part of our curriculum. We created busts and figures in clay and then cast them in plaster. Some folks did ambitious work carving plaster directly. Almost all of this work was presented without paint. It just looks better.
What is the best base used for painting clay sculptures?
You didn’t mention what type of paint you are planning to use.If you are painting on FIRED clay sculptures you may paint acrylics directly onto the clay surface. However, you will get more saturated color results if you paint the surface first with white acrylic gesso, let it dry completely overnight, then paint.Make sure the clay is fired to maturity or thoroughly bisqued. (You may paint on high-fired or low-fired clay. Just look at the cone range information that came with the clay.) If info says “cone 06 - 04,” for example, you may safely fire within that temperature range. This is very important!I was once shown ceramic sculptures in Taos made by a prominent painter who knew little about ceramics. He created beautiful large ceramic sculptures, did not fire them to maturity, then proceed to paint them. Because they were not fired to maturity, they began to fall apart. If they were to be refired to maturity today to try to save them, the entire painted surface would burn off.You can also paint in acrylics over previously glazed surfaces, You can also spray acrylic clear coats or colors.Ken Price used auto body lacquers and acrylics, as Ron Nagle also does today, along with a variety of other media.In terms of a painted, completely CERAMIC surface, Viola Frey used very low-fire overglaze enamels over a white maiolica base glaze with ceramic stains and low fire glazes. She then painted overglaze enamels in the manner of oil paint, let them dry, then fired them.Just remember to work from the HIGHEST firing temperature to the LOWEST.Have fun experimenting! Ceramic possibilities are endless.
For painting plaster of paris mould, what paint is suggested?
Plaster of paris is very porous. You may want to seal it first. A good sealer is watered down pva glue, 3 to 1. After that you can use either acrylic or spray paint. For silver or bronze metallic color spray paint would be easier. Then use an acrylic sealer over the top. Make sure that each coat dries really well before applying the next. I'm not sure how fine the texture is that you're speaking of, but keep the coatings very light. Maybe test a spot on the bottom or somewhere out of sight to make sure it's what you want first. Good Luck!
What type of color works best with plaster sculptures?
To paint the plaster, or to color it as it’s mixed?You can use all kinds of mediums to color plaster, including mineral pigments mixed in paste wax or shellac. If you use paste wax, you can combine mineral pigments and metallic powders to create a translucent surface with a subtle sheen. If you use shellac, you can create a more opaque color and the shellac bonds with the surface of the plaster to create a permanent coating.You can also add pigment to the plaster when pouring it into the mold, but then you need to match it precisely when doing any repairs, which can be difficult to do. This technique works well for direct plaster work, because you can mix a big batch of dry plaster with the pigment before combining it with water, and every batch will be consistent.You can also paint plaster with acrylic enamel, for a hard, glossy finish. I prefer the wax or shellac methods, which allow more light to penetrate the color and reflect off the plaster underneath. But it’s a matter of personal taste and the use to which the sculpture will be put.
