Emulsion Over Oil Based Paint on Wood Nightmare!

Postby Pink11223344 » Wed Feb 26, 2020 11:12 am


I am repainting the woodwork in a house I've moved into. It looks like the original paint was oil based but unfortunately the previous owner painted everything in sight, walls and wood, in white emulsion (it is awful)!

I’ve sanded it all down but a basic sand. So, what's left now is a mix of the emulsion, some of the original oil based paint and also a few bits of bare wood (there were lots of bumps and drips which I've sanded off and ended up going a bit too far) But is all has a 'key' due to the sanding.

What on earth do I now paint on top of this? (internet research hasn’t helped much)

Ultimately, I want the final finish to be oil based eggshell or satin finish.
But what can I put on to start with, water based primer/undercoat or oil based? Having now read up on it, I'm worried that the fact there is still emulsion on there means whatever I put on top won’t stick properly and might peel off. Also, the small patches of bare wood, does this need wood primer first?

New carpets going down soon so I need to get on with it asap and I don't think I have time to more sanding than I've already done (hallway, stairs, banisters and two bedrooms) Also, the rest of the house needs done after this (4 more rooms, hallway and lots of doors) so I’d really like to not have to sand everything back even more than I have done.

I am totally stuck on what’s best to do, and boyfriend says hurry up and decide what we are doing (he’d just slap oil based top coat on and be done with it!)

Apologies if my question has been answered somewhere before, I couldn't find any answers when I looked.

I would be so grateful for any advice. Many thanks!!

Prime any bare wood preferably with an oil based paint to minimise grain lifting. Then coat everything with a high adhesion water based primer/undercoat. I would be using water based satin or eggshell as it dries much quicker enabling multiple coats in a day plus you won't stink the house out or be faced with discolouration of oils. A hybrid like Johnstones Aqua is a good compromise.

Thanks very much for your advice, that's great. I'll take a look at those paints.
