You need to make it waterproof in order to properly paint on paper. This can be achieved with many products, from size to white of egg. I use a transparent acrylic varnish, watered down so that porosity is reduced but surface does not appear brilliant or sticky. | |
 |
The varnish is water-based and this will swell and deform paper. I fix then the artwork to a wooden panel with adhesive tape. | |
 |
I pour a bit of product on the drawing and slant the panel so that the liquid itself slides down. Assisted by a soft brush, I have it distributed in a uniform manner. Use of brush must be extremely careful because it may carry part of the pencil's graphite away.

Afterwards, I lean the panel almost vertical so that the liquid drains, and left it that way until dried. The paper, distended because of moisture, will remain very taut after drying. When shrinking, paper may tear out the adhesive tape so be careful. Paper must be consistent, the kind of paper that, when scratched, create shaving or dust but no cottony fibres. Our drawing will be now between paper and varnish so, unless we have varnish dissolved with alcohol, it will be impossible to rub it out. Good news are that, if we are painting and don't like the results, we can remove paint with no fear of wiping out the sketch beneath. Again, please bear in mind that the varnish layer must be very thin, but never so thin a rubber can delete the sketch. |
