We have decided to paint over some tiles for now with a Dulux Acrylic paint which looks passable as a nice tile for now, however, where there was once silicon on the tiles, the paint will not adhere to them, even though the silicon is gone, something remains, anyone come across this, and have an idea what chemical might remove said barrier?

Acetone is less smelly, WD40 lingers for yonks, White Spirit?

Wherever there has been a trace of silicone even if transferred by a fingerprint paint will roll away.
I am currently relooking my caravan by spraying anything that moves, is plastic and yellowed with Action Anthracite aérosol paint and have been plagued with silicone reactions in crazy places like rooflights, window blind frames etc, car paintsprayers add a silicone product to the paint in the gun to counteract the reaction as it's often impossible to remove the residue.
I got by using another trick that of building up multiple dust coats on the affected areas where the paint is almost dry when it lands & you leave it a long time between coats however if you put one heavier wet coat on even years in the future the silicone reaction will reappear.

If you only need a small amount, I get mine here at the supermarket in the section for "nail polish" remover for the women. Just make sure it is 100% acetone. Do not purchase the "environmental" friendly crap, it is not good.

For a silicone reaction like mine which was caused by a liquid silicone cleaning product Acetone might work on a smooth sealed surface like a ceramic tile but not where there has been silicone sealer applied.
I degreased and scrubbed all my affected areas with brake cleaner & it made no difference.
An oil based primer or undercoat might not react & may form a barrier for your tile paint, that is only a hunch not a recommendation.

Do what a professional would do.
If you have some painters mate or just cheap French silicon just cover up the bathroom mastic and paint it 20 minutes later.

Acetone worked fine, needs a lot of wire wool and graft, but the paint now adheres.........thanks to all here

Many years (at least 20) ago we painted over some bathroom tiles, it was only meant to be a quick fix, we used Thompson's tile paint in cream, it went on beautifully, we are still in touch with the people who eventually bought the house and they still haven't needed to do anything with them and our perfectly happy.
We inherited a yellow kitchen at a future house, out came the tile paint and used a small foam roller and carefully painted the cabinet doors cream, there is absolutely no way you would notice they were once yellow.
