How To Varnish Watercolours

I have just been experimenting with something that I have never considered doing before, varnishing watercolours.
It occurred to me that when visiting a gallery I find myself immediately "drawn" to certain paintings, also I like to look very close up at things like brush marks, paint effects and paint "blooms"  In a mixed show oils seemed to win over watercolours and I think it is mainly because of the reflections.
So... how to get rid of the glass?
Varnish!
This is what I do...
First of all take your watercolour painting and paste the back with PVA (Elmer's in the US I think) do this quite carefully working out from the center of the painting, so that none seeps underneath.

Then place the painting on a piece of mount board that is a bit larger than the picture.  After that carefully cover the painting with some tissue paper or kitchen paper towel.

This protects your still vulnerable painting from the heavy book you are going to put on top of it.  I did a few at the same time so ended up with a stack like this...

Once the front side was dry, after a day The whole process was repeated with another piece of watercolour paper on the back, this is to stop any warping happening.  Another day of drying and then they were cut to the size of the painting

Then I lined them all up in a shoe box (because they were small) and sprayed them with a thin coat of LASCAUX ACRYLIC RESIN FIXATIV When that was dry I did another just for luck!
After that I sprayed a few thin coats both front and back with  LASCAUX UV PROTECT  I guess by this stage you could use any varnish that you would use for oil paintings.  The most important thing I think is the UV protection.
I tested it by pouring hot coffee on it and cleaning with a cloth...it was fine!
After that, when all is dry I framed it like I would an oil painting, Mine usually go on a white backing board with a white frame.  I gave the painting , the found objects that were to go underneath the painting, and the backing board a few coats of matt picture varnish and that was it.

This is one of the framed, glassless, varnished watercolours.
