So, I was feeling quite smug after experiment number one. Watercolour on canvas? No problem…
Then I decided to try an ordinary primed canvas. Utter disaster. Ended up washing it off under the tap. The paint just skittered about on the surface, which I expected, but it seems to fade and dilute. I paint with a lot of water, so unless I really strengthened up my mixes, I don’t think I could get the colour saturation I am after. The grain of the canvas was prominent and not in a good way. The contrast to the Daniel Smith primed surface I used in experiment one was stark.
Muttering to myself, I suddenly remembered a friend had given me a Frisk canvas designed for watercolour. So I hoiked that out of my shed and decided to have a go on that:
The canvas was quite small – 30x40cm and only a cm or so deep, so would need to go in a tray frame I think to give it a bit of substance. The paint went on better, but did not seem as clear or as reactive to texture, as it had on the canvas primed with DS. It could be down to the pigments but I don’t think so, as the quin magenta and diox purple are usually quite lively. Overall, not that impressed.
From this unscientific sample, I would say I much prefer the DS primer.
I looked on Jacksons http://www.jacksonsart.com/blog/2013/09/03/watercolour-canvas/ and they do three brands of watercolour primer – DS, Golden and Schminke. The Schminke comes in fine or coarse, which might be interesting. But for now, I will prime a few more canvases and carry on….
