Poor adhesion of waterbased paint on acrylic solvent based primer coat

Dear,
I have encountered an adhesion problem when using waterbased coatings as topcoat on the dried acrylic solvent based undercoat on wood products. I really can not figure it out what was wrong with it. Could you help me in this matter

Thank

Best Regards

I feel that the acralyic basic coating has to be little rough for your top coat of water based coating. Try roughing it with 00 emery paper lightly on a sample piece.

Many paints fail because of lack of adhesion.
