I've even had the hair dryer on it and it is still not dry . I suspect the manufacturer has used beeswax because it feels waxy . I'm tempted go the local Crown Paints and buy some oil based house paint , can't see why that won't work?BUT, that's a trait of oil paints. They take a much longer time to dry than acrylics. Usually this is a positive as it allows more blending time and time to make corrections. Though it can be frustrating at times when you're waiting for layers to dry. It'll also depend which colors you used, how thick you painted and if you added any solvent/oils to your paint. These will all alter the dry time.
You'll find all oil paints will take significantly longer to dry than acrylics though.
I'm an expert painter and decorator , I do understand how paint works but when I tried the oil based art paint I was shocked by the drying time . I could get some OIl based house paint dried fast so I don't understand why this art paint isn't even sticky yet . Beeswax and linseed oil keeps paint open , we sometimes use this in decorating but even that dries fast compared to this art paint .Beeswax can linger in drying a long time and this art paint does seem waxy .Oil paint dries via an oxidative process where the oil reacts with oxygen to solidify. So it isn't simple evaporation of water.
Acrylic and watercolor go through evaporation, whereas your oils basically have to go through a chemical reaction.
I can see why people do abstract art with oils , do it in one sitting then plenty of time to mess about with it . I was expecting a stickyness that just isn't there. I can do wonders with house paints , marble effect , paint and grain etc , perhaps I should try house paint lol .Beeswax helps paint cure faster. It may react with house paint differently but beeswax definitely shortens the cure time with artist oil paint. Some oil paints take months to cure depending on the thickness of the film.
weeks lol , oh my , I want it dry within hours so I can do the next bit . I might try an abstract , paint it all wet and merge colours . That way I can leave it for weeks lol because it willl be finished .I use beeswax and thick paint on paper and it is dry within weeks. Normally would be months.
