Now the tricky part; adhering the painting to the board. The paper is about 2cm bigger all around. I cover the back of the painting and front of the board with a thin layer of Liquitex Matt Gel.
Working quickly, I lower the board onto the paper then flip the whole thing over. Using a large sheet of tissue paper and a hard roller I roll, working from the centre out to edges, gradually forcing any air bubbles out. When satisfied I pile lots of art books on to cover the whole surface, about 4 deep and leave overnight.
