The Eradicator Brush – Rosemary & Co


The Eradicator Brush from Rosemary & Co is the long sought solution to those unintended watercolor brush marks resulting from too much enthusiasm, haste or miscalculation. Watercolourists use this specialist brush to create highlights and texture on paintings after the paint has dried and to tidy up ugly edges and mistakes with it. It’s a flat, stubby brush with bristles stiff enough to remove the dry paint but soft enough to not damage the paper. Good quality watercolour paper will withstand the erasing process as long as the brush or paper is not too wet or the user is too heavy handed!

Caution: too damp a brush and/or too vigorous “erasing” may damage the painting/paper.
