Masking Fluid Liquid Mask 32 ml, VALLEJO – liquid mask for model painting and airbrushing

VALLEJO Liquid Mask 32 ml is a removable masking fluid formulated for model painting and airbrushing. It creates a flexible protective film over areas you want to preserve while applying new paint layers, washes, glazing or weathering. The product is suitable for use on plastic, resin and metal miniatures and scale models, and is designed for fine details, edges and hard-to-reach spots. After drying, the film can be rubbed off with an eraser or soft cloth to reveal the reserved surface.

Advantages

Liquid Mask provides a thin, flexible coating that adheres to common modelling surfaces and peels away cleanly when dry. Its formulation allows masking of very small details without damaging underlying paint, and it can be applied by brush for controlled placement. The product supports layered painting techniques and airbrush workflows by protecting selected areas during multiple passes of color or weathering effects.

Suitable for

• Masking fine details on plastic, resin and metal miniatures
• Protecting edges and recessed areas during airbrushing
• Reserving areas before washes, glazes or weathering
• Creating sharp boundaries between colors during multi-stage painting

When it may not be suitable

Liquid Mask is intended as a temporary protective coating and is not formulated as a long-term adhesive or structural filler. It may not perform well on extremely glossy or contaminated surfaces unless these are cleaned or lightly abraded first. Very porous or heavily textured surfaces can make clean removal more difficult and might leave residues that require gentle cleaning.

Key specifications

• Volume: 32 ml
• Form: liquid masking fluid
• Compatibility: plastic, resin, metal modeling materials
• Application method: brush-on
• Removal: rub off when dry with eraser or soft cloth

How to use

Apply an even, thin layer of the liquid mask to the areas you want to protect using a clean brush. Allow the film to dry fully before applying additional paint layers, washes or airbrushing. When masking is no longer required, gently rub the dried film off with an eraser, a soft cloth or a fingernail, taking care not to damage fragile details or fresh paint nearby. If residue remains, use mild solvent recommended for model paints and test in an inconspicuous area first.

What to consider before purchase

• Ensure the masking fluid is compatible with the substrate (plastic, resin, metal) and any paints or primers already applied.
• Check that you have suitable brushes and tools for precise application and removal.
• Consider performing a small test on a scrap piece or an inconspicuous area to confirm drying time and clean removal.

Usage recommendations

Use a dedicated brush for applying the liquid mask and clean it immediately after use. Allow complete drying before painting over the mask and remove the film gently to avoid damaging delicate model surfaces. For better adhesion on glossy parts, lightly scuff the surface and ensure it is free of oils or dust.
