Repairing an Annie Sloane chalk piece.

Have you tried wiping it with white spirit to dissolve the wax?
If the surface is flat, I’d undercoat with water based primer, then paint over with a soft sheen (satin) wood paint.

I can recommend Rustoleum satin finish furniture paint, you can paint it over the current finish, and it looks really good - the only limiting factor is that it doesn’t come in a huge range of colours.

Sorry should have said once the wax is removed as J52 says.

I painted our kitchen cupboards with this chalk paint and it cost a small fortune. I hated it and only waxed one cupboard to se if it improved the look. It didn’t! We gently rubbed it down and used white spirit to get the wax off. Then painted over it with a run of the mill kitchen paint. Looks great! I would never use this chalk paint again either.

Thank you. I have a friend who has renovated most of her home with chalk paint and loves it. I just thought it looked as if it needed doing properly, just not for me.

I'd buy a tin of Nitromors.

I’ve also painted over Annie Sloan using Rustoleum from Homebase. Works fine.
