I'm preparing some canvases with several coats of gesso and sanding in-between each layer to make the canvas smoother, and a thought popped up in my head.
I've been wiping off the dust from sanding with a slightly damp cloth in the thought that I do not want any "dust" to get into the next Gesso layer, but now that I start thinking about it, the dust is Gesso as well, maybe I'm doing something which is completely redundant? Does the dust bind into the next layer like normal Gesso?
I'm waiting about 24h in-between each session of sanding and applying the gesso so I assume the Gesso is fully cured by the time I sand it.
So my question to you guys is, do you wipe off the sanding dust in-between Gesso layers? Does it matter if you do or do not?
And then I wonder, do you sand the final layer? Or leave it un-sanded?
