Hello @chloepatto
Welcome to Bunnings Workshop! Thermofoil doors or vacuum laminated doors are sprayed with a very strong adhesive and a vacuum machine sucks the laminate literally on to the board. This vacuum process causes the adhesive to travel in to the MDF. The other method is machine pressed laminate and it produces the same effect. I would recommend using a glue remover but it would damage the MDF. Instead I recommend doing a heavy sand of the surface to create a very rough surface for the undercoat to hold on to. I suggest using Dulux precision primer sealer binder. This should give you superior holding power and will work for your doors. I would love to see some pictures if you can post them so that we can have a better idea of your project. If you have any other questions or anything else we can help with please post it here on workshop.
Cheers,
Red

Welcome to the Bunnings Workshop community @chloepatto. It's wonderful that you've joined us, and many thanks for your question on adhesive removers.
It looks like @redracer01 has just beaten me to a response. Instead of repeating everything he's said, I'll just second it. The adhesive is more likely in the MDF than on top of it, and no amount of adhesive remover will budge it.
He's also recommended Dulux 1L PRECISION Maximum Strength Adhesion Primer White as I would have. I've been using it lately on various surfaces that normal undercoats have issues adhering to, and it has been fantastic.
I'd be keen to see those pictures too.
Please let us know if you have any questions.
