Christmas painting jobs

Just thinking that there are a few paint jobs that I need to get done over Christmas. In the past, I've used 'real' gloss/undercoat etc and, latterly, Crown Solo gloss has given good results. The downside of these is that they take some time to dry, especially when it's a bit cooler. Then, of course, there's the whole business about yellowing when there's no sun on it using post-2010 solent based paints.

So I was thinking about giving water-based paint another chance (1). The last time I tried this, the biggest problemn I had was adhesion over existing gloss, despite giving it a good sand over first. I assume it was too ambitious to expect to use it without undercoat.

I've had a bit of a Google around and, as expected, there is no real consensus on which paint is best to use. The brand that seems to draw the least criticism seems to be Johnstone's Aqua. Not very readily available on the retail market but I'm sure I could source some.

Does anyone have any positive experiences with any alternatives to Aqua, before I invest 50 quid in a pot of paint and one of undercoat?

(1) Can't believe we have to worry abotu whether paint will work in 2013 but that's progress for you!

I think with water borne acrylics you can have gloss or adhesion but not both. Nature of the beast I fear

Ordinary emulsion goes onto oil based paint, it just takes several coats to form a full film.

Yes, apparently on some of the most recent airliners, the normal paint is not adhering as well as before, no doubt due to the exotic materials being used now.

The way things are going perhaps diyers will turn to making their own paints again.

Easy to get PPG products such as Johnstone's from their own shops:

...potentially leading to some much more dangerous outcomes than simply having a little bit of solvent in the air for a short period of time.....

Thought I should tail this one off:

I got hold of some Johnstone's Aqua gloss (and their recommended undercoat) and finally got around to using it. Compared to other water-based gloss I've used in the, it gave very good results, with a pretty uniform coverage and a convincingly gloss finish. I used a decent-ish synthetic brush, as recommended by the blokey in the Johnstones outlet. Only used it on 'fresh' wood so far (primed and undercoated twice), so have no idea how it would go over existing gloss. The only downside I found i that it seems to start going off very quickly, so there isn't much time to lay it off. Part of the job was a new door in a frame I had previously (~6 months ago) painted in Solo white gloss. The new paint shows up the yellowing in the previous gloss quite distinctively, so it looks like I'll have to go over that pretty soon....

I find that I have had to add a touch of water to quite a number of the better (so-called) water-based paints. Really seems to need only the tiniest amount - even if the first use from the tin is OK, the next use seems to need that.

Sounds like these acrylic topcoats are improving then. The technical problem is getting them to perform over a range of temperatures. In controlled conditions you can have any finish you like without solvents, but a consumer product has to form a proper film at freezing, at 25 degs, and everything in between. Impossible task for the manufacturers
