I’m no chemist, and not advocating it as general practice, but a drop of Fairy in acrylic paint seems to overcome cissing if applying acrylic over a cissy surface - dont know why it works, but no denying it has a tiny place in the armoury if you are in a bind. I can;t paint fast enough to create a froth.
Just a thought but I think washing up liquid breaks the surface tension. So where the paint might pull back from the surface it can’t. Not sure how to explain that more scientifically but it makes sense in my head
If I am right this might be a temporary fix because in theory, although the paint is flowing better, if it is flowing over a surface with polish or wax it means that particular section has a coat of paint that hasn’t adhered to the surface but is supported by the paint around it. In time it might lift or split.
