|Red Evening Gouache on mdf 8x10|
Working in gouache for plein air sketches has become more popular in recent years. There is some great work done by Scott Christensen , Kathleen Dunphy and Carol Marine to name a few. In this time of Covid, with no workshops and little gallery activity, I am finding time to play and try new things. So why not try gouache.
I worked in gouache at the Watts Atelier in California a decade ago. A gouache class was recommended before working in oils - as the gouache can be reactivated and blended making a good first step in portraiture etc. I can remember enjoying the medium. Today my interest would be in plein air landscape, working with a fast drying medium requiring a limited amount of equipment.

My next issue was the surface and the general need to frame the pieces behind glass. Most would be simple sketches on watercolour paper but hoped that I could work on surfaces and seal them to avoid the need for glass. I worked on mdf board, illustration board and terra skin ( stone paper). Each was a unique experience with a unique result. The paint reactivates immediately on contact with water. I first tried lightly brushing an isolation coat (a sealing coat used on acylic paintings) with a soft brush. Seals well but cannot avoid activating some of the paint. Also results in a semi gloss finish which is not what a lot of gouche painters want - they like it flat. I , on the other hand , I like some degree of finish. So then I tried hair spray ( what I use to secure a graphite or charcoal sketch). One spray reduced the activation but two or three make the paint more secure. With that I could apply an isolation coat without difficulty - so I had an option for hanging without glass. I also tried an acrylic based varnish spray wich worked well - but even in an open garage was difficult to cope with. But at least I know that I have choices if I wish to hang without glass.

What really pleased me was how well it worked on mdf board coated with gesso. So I had an archival cheap surface with the possibility of securing the finish - but accepting that it would be semi gloss - not the "true" flatness of the medium.
I also tried adding "tooth' to each of the surfaces using a layer of Liquatex Clear Gesso - which leaves a grainy finish I quite like.
So now to paint. Had the box out a few times and also tried a few pieces in the studio. It is a mark-making layering medium, much like how I paint with acrylics - so I think I might like it. It is very fast to work with - less than half an hour on each quick sketch. Great for travelling.

So what have I got. A small light plein air kit that contains all I need and using dried gouache to be reactivated on use. Simple, cheap, easy. I think I like it. Will see how it goes.
