Aquabord (ideal for watercolour, poster colour, gouache and ink) absorbs the medium quickly, allowing you to work in glazes without altering the under layer. Unlike watercolour paper, you can lift off colour without leaving marks. This eliminates the need for masking or adding harsh white highlights to paintings.
TIP: Wet the surface with water before working. As air bubbles come to the surface they will pop in your work creating small white dots – this can be an interesting effect!
