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?
Its a concern cause its a keychain i am planning to make

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 & 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.

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.
