LUKAS Oxgall is a specialised wetting agent for watercolours and gouache. It enhances flow when mixed directly with paints, especially on difficult-to-wet surfaces such as hard-sized papers, by reducing surface tension. For best results, dilute with a small amount of water and blend separately with your colours on a palette.

This product makes watercolour application smoother and more consistent, particularly on greasy or less absorbent surfaces, improving overall paint handling.
