I've previously used a coat of white emulsion paint (i.e. for painting interior household walls) on paper and wood to act as an undercoat, and then painted acrylic on top. This has worked fine for me.

I'm about to start doing the same with boxed canvas, I can't see that this should cause any problems but does anyone know for sure please?

I don't see why it wouldn't work. Acrylic is pretty "elastic". It may have an adverse effect under an oil painting, but as long as it's dry prior to the painting, you should be fine. May I ask, why don't you just use gesso?

Emulsion or house paints have a lot of additives and stabilizers added from what I am told. That also doesn't account for things like fungicides, etc.

If you are a hobby painter and feel it is agreeable with your work, then by all means, knock yourself out. Have a ball.

If you are trying to become a selling artist, in my humble opinion, things change a bit. You owe it to your work and your customer to use materials intended for the job at hand.

Others may disagree but then I don't always speak for others.

And in another forum, a long one, Gesso coating or paint primer? (http://www.wetcanvas.com/forums/showthread.php?t=170002)

There are wildly-divergent opinions on the suitability of commercial water-based housepaints paints used with or as a base for acrylic paints. Some of the information passed on by the "I'm in favour" camp, from people working in the industry, sound persuasive but personally I remain unconvinced.

I'd say no, for the same reasons as Howard. Though it is fine if you're just experimenting or painting for enjoyment. :) Just my opinion but I wouldn't sell work done with student grade paints either.
