## Summary description

VALLEJO 28.850 is an 85 ml hobby paint medium/additive supplied in a plastic dispenser bottle. Designed as a liquid mask/medium compatible with model paints, it facilitates masking, blending and modifying paint behavior on miniatures and scale models. Useful for controlled masking, glaze effects and adjusting paint flow during detailed painting work.

## Long description

Vallejo Liquid Mask is a water-based masking medium designed to protect areas you want to remain unpainted during hobby and model painting. Supplied in an 85 ml plastic bottle, the liquid mask spreads easily over surfaces and can be removed after the paint has dried to reveal the reserved area.
Advantages
This liquid mask offers controlled application and reliable adhesion to common modelling surfaces. It dries to a removable film that can be taken off cleanly with an eraser or soft cloth, simplifying multi-stage painting and detail work.
Suitable for
 Masking small areas on plastic, resin, and metal model kits
 Protecting details during airbrushing or brush painting
 Creating crisp edges and layered paint effects on miniatures
When it may not be suitable
Liquid mask is not intended as a permanent coating and should not be used where long-term protection is required. On very porous or highly textured surfaces the mask may not form a completely even film and removal could be less clean.
Key specifications
 Volume: 85 ml
 Formulation: water-based removable masking medium
 Container: plastic bottle with dispenser
How to use
Apply a thin, even layer of liquid mask to clean, dry surfaces using a brush or applicator. Allow it to dry fully before painting over the masked area. After the overcoat is thoroughly dry, rub off the mask gently with an eraser or soft cloth to expose the unpainted surface. If necessary, clean residue with mild soap and water once masking film is removed.
What to consider before purchase
 Confirm compatibility with the material of your model (plastic, resin, metal)
 Plan drying time before applying paint
 Consider working on small test areas to check removal cleanliness
Usage recommendations
For best results apply in thin layers and avoid very thick coats; ensure the mask is fully dry before overpainting and remove it after the topcoat has cured to prevent paint lifting.
