Painting & Decorating Question

Water based satin over primer designed for solvent gloss

I have used a primer ready for gloss but I now want to use water based satin. It's taken many hours sanding and priming 3 floors ready for a solvent based satin. After starting to paint the top coat, it has a tinge of yellow. Now I want to change to water based satin to keep it's brilliant white colour. Rather than re-sanding 3 floors can I just paint over the solvent based primer with water based satin? Whats the best /worse case scenario?

Painting with water over oil is never a great idea, it might be okay for a short period, but may eventually crack and peel. For the time it'd take, I'd go back to the start and re-prime it, then go for your water based satin. Probably not the answer you were hoping for!

If you insist on finishing the floors with a water based, then I would recommend that you lightly sand the floors with a 120 grade, then apply a coat of Dulux supa grip primer prior to finishing with the water based satin. The supa grip primer has good specific adhesion and will provide a key. Just a light sand will suffice to ensure a key.
