Yes, even though fixatives help fix the pastel dust to the paper, they do not form a complete barrier by any means. Pastel dust can still be smudged, smeared and come off on your hand after fixing.

Re: spectrafix...the non-toxic fixative

EMMAJI, one thing I've done on sanded papers (most often Wallis) for many years is to scrub the pastel down into the tooth of the paper using a foam house painting brush. I use a fairly dark or staining color if I want more than a ghost of the color left.

Sometimes I put a layer of very dark color down and then spray with water and brush it in. When it's dry it's much more fixed in place, ready to paint over (and perhaps with a coating of SpectraFix might even be less inclined to come off). However, even then it has a tendency to smudge a tiny bit on your hand.

If I want a fixed colored ground behind something (again on sandpaper), I paint a layer of gouache. When it dries completely it has enough tooth for the pastel to adhere over it. It has the same kind of 'dusty looking' quality that pastel has, and the colors can be quite strong. Works like a charm!

Also, even though the paper was taped down. it warped slightly.

So, methinks Spectrafix takes some experimenting, that's for sure............and is not a magical solution for everything...........

This begs the question.....WHY put down a pastel base colour before painting? You can never use a fix like varnish, to give you a perfectly dust-free surface, and you will fill up the tooth of the paper, even tho the fix will give yuo a bit more tooth back, it may not be enough.....so why not find another way of colouring the paper....if that is what you are determined to do? Deborah's suggestion of using gouache is a good one, because its matt finish is chalky and accepts pastels well. Kitty Wallis uses Createx Pure Pigments, which are waterbased. Watercolours are another option. I would not use acrylics because they are, essentially, plastic and used too heavily will clog the paper tooth and give you a slick surface, not good at all. You can use oil paint, thinned with plenty of turps to give you a runny wash. And I know there are stacks of posts here about the use of an alcohol-over-pastel thing. My choice would be inks or gouache or watercolour.

However, there are so many wonderful coloured surfaces around, both paper, and boards, which give you a great start. Unless you are sitting there with reams of white surface which you want to colour, there is really no need to give yourself a hard time by creating a surface which is then difficult to work on without smudging it!

I think they are called Preval or something like that.

I use the PreVal exclusively for my homemade fixative. It works wonderfully (a needle and/or hot water will unclog it if it does that), and is recyclable (no CFCs).

Btw, I saw Casey Klahn use Spectrafix on his LaCarte painting and the coating held!
