Acrylic-Polyurethane Varnish VALLEJO 200 ml Glossy — universal protective finish for models and miniatures

VALLEJO Acrylic-Polyurethane Varnish 200 ml Glossy is a clear, water‑based protective finish designed for models, miniatures and hobby projects. The formulation combines acrylic resins with polyurethane modifiers to provide a glossy, non‑yellowing topcoat that seals paints, inks and decals while increasing surface hardness and chemical resistance. The product is supplied in a 200 ml container and is suitable for both brush and airbrush application, offering a durable finish for display pieces and handled models.

Advantages

This varnish delivers a consistent glossy sheen that enhances colour depth and protects painted surfaces without altering base tones. Its water‑based acrylic composition keeps odor and volatility low compared with solvent systems, and the polyurethane content improves scratch and solvent resistance. The varnish dries to a clear, non‑yellowing film and is compatible with common model paints and decals when applied according to instructions.

Suitable for

• Sealing painted plastic, resin and metal miniatures
• Protecting decals and transfers on scale models
• Providing a display‑quality glossy finish for dioramas and display pieces
• Topcoating hobby projects finished with acrylic and water‑based paints

When it may not be suitable

This gloss varnish is not recommended for direct use over delicate or solvent‑sensitive finishes without prior compatibility testing; some lacquer or solvent‑based paints may soften. For a matte or satin appearance, this product will not deliver the desired sheen without further treatment (e.g., overcoating with a matte varnish or using a flattening agent).

Key specifications

• Base: water‑based acrylic with polyurethane modifiers
• Finish: glossy
• Container volume: 200 ml
• Application methods: brush and airbrush
• Properties: non‑yellowing, increased hardness, improved chemical and scratch resistance
• Suitable substrates: plastic, resin, metal, painted surfaces and decals

How to use

Ensure the surface is clean, dry and free from dust, oils or residues. Shake the bottle well before use to homogenize the formulation. For airbrushing, thin only if necessary with water or a manufacturer‑recommended thinner and use suitable nozzle size and pressure; test spray on scrap material first. For brush application, use a quality synthetic brush and apply thin, even coats to avoid pooling or brush marks. Allow adequate drying time between coats as indicated by ambient temperature and humidity; multiple thin coats give the best gloss and protection. Clean tools with water immediately after use.

What to consider before purchase

• Intended finish: choose glossy if a high‑sheen protective topcoat is required
• Compatibility: test on a small area if using over solvent‑based paints or unusual substrates
• Application method: confirm whether you will use brush or airbrush and prepare thinners/cleaning supplies accordingly
• Drying conditions: allow for adequate ventilation and appropriate temperature to achieve full cure

Usage recommendations

Apply thin, even coats and allow full drying between layers to achieve a durable, glossy finish. When using on display or frequently handled models, consider two or more light coats for improved protection and a smoother surface. Perform compatibility tests before applying over solvent‑based or specialty paints.
