Is there anything i can coat waterbased paint with to make it waterproof?

Planning to make some small art items but they require watercolours. The thing is, i am worried that the paint would come off or smurge everytime it comes into contact with water/sweat.


Is there anything i can coat the things with to make it waterproof? Best if that coating is easily available. If not then will oilbased paint have the same prob?

This isn't as complicated as it sounds. Use a good quality acrylic spray varnish made for fine art - like Krylon Crystal Clear. A spray varnish won't pick up %26amp; smear the paint beneath.





Contrary to belief, acrylic gels and mediums are not completely waterproof - these emulsions leave microscopic holes when they cure which absorb moisture and dirt. The surface of oil based paint remains soft until cured (weeks to months) and even then should be varnished as well. Spray Fixative is not impermeable and is not suitable as a final varnish.





Only a varnish will create a completely impermeable surface.Is there anything i can coat waterbased paint with to make it waterproof?
You can use spray fixative to protect watercolor. As a side note, you can also use fixative between coats if you don't want them to bleed together. Just do a search on spray fixatives to find a brand that appeals to you.
Hi:





You might try a fine spray coating of a fixative or sealer, and then you could brush an acrylic matte gel over it - that will pretty much make it as waterproof as possible - I'd probably put a few coats on it. The matte gel can be used as a collage medium. I don't know that it is competely submergably waterproof, but on DIY's B Original, I've seen it used to coat rocks with collage elements and used either in or very close to a fountain.





You can get the matte gel medium in a variety of formulations - I prefer to use the matte (or non-shiny) over a gloss or satin finish. Some manufacturers of these mediums are Golden and Liquitex, and these are pretty easy to find at any art supply store. I would just spray it first with something like a sealer so that when you brush over the face of the item, it won't smear. I can't find mine right now, but it was a type of matte finish spray that I got at a Michaels or Hobby Lobby art and craft store. In place of a gel coating, you might also try a something like a polyurethane type furniture finish, but I haven't used those before. Another thought would be to use a clear embossing powder, and melt it over the piece in something like an oven - that would probably make it waterproof, and it would probably keep it fairly heat-proof unless you would bring it back up to its melting point.








Oil based art paint creates a durable surface, but it really also probably needs to be varnished or sealed, too.





Some on-line sources of the gel mediums are Dick Blick and Jerrys Artarama, Art Supply Warehouse, and Cheap Joes.





I have a BFA in painting, so I do know a little bit about these materials, but I would also try a sample test to see how it works before messing up something. I truly hope this helps, and good luck with your project.
