Product name: Masking Fluid Colorless/Masking Fluid Colored Contents: Ammonia-free synthetic resin. Basic Information: Masking fluid is used to cover areas that are not to be painted on smoother, oil-free, and dry surfaces (e.g., illustration boards and similar) (20ml, 100ml, 200ml). Properties: Colorless and blue. Transparent. Ammonia-free. Odorless. Usage: · Stir if necessary before use. · Masking Fluid is ready to use. Apply with a cotton swab, wooden stick, or pen nib. Do not use with your high-quality brushes! · This product can be thinned with water but dries in a very short time to form a rubbery, transparent layer. · After the masking fluid has dried, the masked picture can be painted with watercolors, gouache, or Aerocolor inks. Drying time may take anywhere from a few minutes to slightly over an hour depending on the thickness of the layer. · Once the painted layer is thoroughly dry, you can remove the dried, rubbery masking fluid layer by carefully rubbing it with a clean, non-greasy finger. (Please do not tear it off.) · Masking fluid should not remain on the painting surface for more than 2 days. Otherwise, it may cause yellowing. · Not for use on very soft surfaces like parchment or linen. · Close the cap tightly immediately after use. · Store in a cool, dry place. · Protect from freezing. · Test before use.
