    Grounds / Priming Oil Paint Other
    Question

    ​Hello Everyone,

    Im currenty grinding my own colors and starting to paint with them. But im running across a problem and thats the beading up of certain colors.  

    After trying to find answers online , it seems that this occurs because  my surface has a  lower surface energy than the paint.  If this is correct it seems that I have two options, I either have to change the surface or change the paint.  

    Would spraying alcohol on my surface work? Or thinly oiling out and letting it dry? What can I put on the surface that would make the paint stick better?  Can I add something to my paint?  

    P.s. I cant sand the surface since i did an underpainting and i dont want to damage it. 

    Best Regards,

    Hector

    I would not spray alcohol especially on unaged oil paint films, alcohol is too polar for fresh films. Applying an oily layer and letting it dry will cause many other issues (please search “oiling out” here). Sanding is probably too aggressive. Perhaps first try to make a slurry of calcium carbonate in water and massage the area using silk or a soft cloth and very gentle pressure until the sheen (or oil skin) is reduced. See if that helps reduce the beading before anything more aggressive.
