Painting over existing paint, what did I do wrong?

Thanks, can I paint some oil based directly on top of the oil based instead? Might be cheaper in terms of time.

Thanks I'll give that a try on the next room!

If you want to do the job properly and not have any problems scrape the aqua enamel off. Sand the trim with an electric sander or by hand until the surface is smooth. Clean the surface and allow to dry. Apply a coat of oil undercoat. This should seal the surface and stick to the existing surface. Let the oil undercoat dry for a minimum 24 hours then you can lightly sand and apply water based or oil based top coats.

Or replace the timber (no sanding) Undercoat and paint

While the most difficult option, it will give you the opportunity to raise the power point to legal/best practice height.

Would be good to replace them but it's a big job as I would have to replace picture rails and all the other bits of timber around the doors/windows etc...

Are there any health risks with sanding off the old oil based paint, lead etc....?

Oil based is ok to sand but if the paint is very old get yourself a lead testing kit to be sure and get advice if there is lead.

This is the exact reason that for us tradesmen the reality television reno revolution is the best thing since sliced bread..
We love nothing more than these exact situations where amateurs get it completely wrong because the "Paint expert" at the Bunnings counter
Advised this was the best course of action without attending the job site...

When tradesmen are called to remedy these situations the job has been made twice as difficult and We charge accordingly because We love nothing more
than trying to make good on a botched Job..

OR you could suggest how you would go about fixing it so the eager DIYer can have a go.

Thanks house is over 100 years old and still has lots of orignal features so I'l play it safe and just roughen up the top layer of existing paint, I can replace the skirting boards completely when I refloor. The other timber isn't as big of an issue as it doesn't get as much impact from feet etc... and the doors can be taken outside for sanding.
