Perfect for use with oil paints and oil pastels. The Arches Oil Pad is 100% cotton with a semi-absorbent surface that is prepared with a size and an oil barrier. It can be used with or without an additional primer. The paper has a fine grain similar to the texture of a stretched canvas. Resistant to scratching. Prevents greasy rings forming and protects the fibres from oxidation in contact with the paint. Very tolerant to solvents. The paint sits on the surface for an excellent rendering of the colours and faster drying times. 300gsm.
