Schmincke
Masking Fluid Neutral 25 ml

Colourless masking fluid for specific areas. Stays white on watercolour paper and photographs. Can be applied directly from the bottle. Colourless when dry. 

When dry, the masking fluid can be painted over with watercolour or gouache. Should not be left on more than two days and must be removed entirely, otherwise there is risk of yellowing. The fluid can be mixed with water but dries quickly and cannot be resolved in water after. 

Seal the bottle as soon as possible after use. Keep it in a dry and cool place.
