Acrylic primer not adhering to painted surface - what am I doing wrong?

I have obtained a family heirloom by way of a small kids buffet, which I am in the process of restoring for my daughter. I've sanded it back, applied putty where necessary, sanded the hell out of it and as I'm going to use a Dulux enamel paint to finish the buffet, I had a look at the Dulux can, to see which primer to use. It specified that I use a Dulux acrylic primer/undercoat but that priming was not necessary if paint was in ok condition. The paint was in ok condition in most places, but as I did a fair bit of filling, I decided to prime the whole thing. Well, the bloody primer hasn't stuck and is peeling off!!!

What have I done wrong? I thought applying the primer over the old paint would be a sure fire way to make the new paint stick. Should I have used another sort of primer instead? And how do I now remove the primer that's peeling (other than peeling it all off bit by bit)? I'm not that big a fan of using paint stripper, as I'm pregnant, but if I have to, I can always get my husband to do it (even if I do think he won't do the job as well as I will).

Here's hoping someone out there can help me. Thanks in advance!

It sounds like an oil or something similar is blocking the primer from penetrating the wood and causing it to lift when it dries. Might need a was down with some sugar soap or similar.

There is a line, oil over water but never water over oil. You can get a prep product that will provide a good key. One of the three in one undercoats should do it. Go to your local paint shop they will be able to give you what you need.

Thanks so much for the help guys. I have some ESP on hand - should I use that?

In the meantime, does anyone know how to remove the primer?

Don't use ESP. Use a shellac primer such as Zinsser BIN primer or Prep-lock.

Paint stripper might be easiest, failing that sandpaper. I'd use stripper then prep-lock

Thanks heaps for the advice. I guess I'll strip the thing and start over again, this time with some of that Zinsser stuff. Looks like all my work was a giant waste of time. I was actually originally going to use an oil based primer, but my father in law said I HAD to use acrylic, hence I went with his suggestion and the suggestion on the paint can. Yay!!

Hi Lotte,
Personally I prefer to use oil base paints on timber as it seems to key to the surface better and the enamel dries much harder - read more durable than acrylic. The oil also helps seal/preserve the timber as well. In fact, I usually add a bit extra linseed oil to the primer, particularly if the timber is very old and dry.
Acrylic seems to do a better job on the plasterboard/render/hardiflex/MDF/ synthetic type materials.
Just my 2/- 's worth

Like a lot of furniture this piece may have been cleaned with Mr Sheen or some other silicon based cleaner and there are a few of them around. If so then it's likely that enen stripping right back to bare timber may not do the job.

If it still doesn't stick properly a coat of dewaxed shellac should seal the yucky stuff into the timber and allow the paint to work.

:U

Shellack; universal primer - everything seems to stick to it.
If stripping is ness. try Citrusnstrip (TM) or any other of the citrus oil based strippers made from the rinds of oranges, lemons, limes. This stuff is almost edible! - works just as well as the amonium choride horror liquid stripper.
Someone mentioned silicone. Could be the core of your non-sticking problem.
Good luck

Lotte, I am impressed !!!!!!!!!!!!!!!!!!!!!!!!!!
First time I have ever heard of a daughter-in-law listening to, let alone doing as a father-in-law suggests:-)

Thank you everyone! It's still sitting as I contemplate what to do next. I think I'll do the citristrip and start all over again. It's on the front deck and I'd REALLY like to get it off and finished ASAP so that we can have the deck back, but motivation is hard to come by at the moment :-)
