Koh-i-noor Acrylic Varnish 165545, Matte Finish, 500 ml

Koh-i-noor Acrylic Varnish in Matte Finish is an essential, professional-grade topcoat designed to provide lasting protection and a refined final appearance to artworks created with acrylic paints. This 500 ml water-based varnish creates a durable, non-yellowing barrier that shields paintings from dust, UV rays, and minor physical abrasion. By delivering a uniform, non-reflective matte surface, it eliminates distracting glare and enhances the depth of colors, ensuring your finished work is preserved and presented with a professional, gallery-quality finish.

Key Features & Technical Properties

• Dual Protective & Decorative Function: Serves as both a protective shield for the paint layer and a finish that determines the final visual effect of the artwork.
• True Matte Finish: Provides an even, smooth surface with zero shine, allowing for optimal viewing of the artwork without light reflections.
• Water-Based Acrylic Formula: Easy to apply, low in odor, and tool cleanup is simple with soap and water. Resists yellowing and remains flexible over time.
• Versatile Application Methods: Can be applied with a soft brush for control or thinned for spraying, ensuring a smooth, drip-free coat suitable for all skill levels.
• Universal Compatibility: Specifically formulated for acrylic paints and suitable for use on all common painting surfaces: canvas, wood, paper, canvas boards, and more.
• High-Capacity Packaging: The generous 500 ml quantity in a practical, resealable plastic bottle offers excellent value, ideal for multiple projects or large-format artworks.
• Part of a Cohesive Range: Available in matte, gloss, and metallic finishes, allowing artists to choose the exact sheen to match their creative vision.

Primary Benefits for Artists

• Long-Term Artwork Preservation: Seals the painted surface from environmental pollutants, dust, moisture, and UV radiation, significantly extending the artwork's lifespan.
• Professional Surface Unification: Evens out the final sheen across the entire painting, which is particularly important when different paint colors or mediums have dried with varying gloss levels.
• Enhanced Visual Appeal: The matte finish reduces surface reflections, allowing colors to be perceived as richer and more saturated, especially in darker tones.
• Facilitates Safe Maintenance: Once fully cured, the varnished surface can be gently dusted or carefully cleaned with a damp cloth without risk of damaging the original paint.
• Reversible Conservation Practice: As a conservation-conscious material, this removable varnish can be taken off by a professional in the future if restoration is needed, protecting the integrity of the original piece.

Recommended Surfaces for Application

• Stretched canvas (primed)
• Canvas panels and wooden boards
• Heavyweight paper and illustration board (sealed with gesso)
• Acrylic paintings on plaster, stone, or terracotta
• Important: For oil paintings, pastels, or charcoal, use a fixative or varnish specifically designed for those media.

Step-by-Step Application Guide

1. Ensure Complete Curing: The acrylic painting must be absolutely dry. Allow at least 1-2 weeks for thorough curing before varnishing.
2. Prepare the Artwork: Remove all dust and loose particles from the surface using a soft brush or compressed air. Work in a clean, dust-free environment.
3. Prepare the Varnish: Shake the bottle well. Pour the required amount into a separate container to prevent contamination of the main supply.
4. Applying with a Brush:
   • Use a clean, wide, soft synthetic brush.
   • Apply thin, even coats using long, uninterrupted strokes in one direction.
   • Avoid over-brushing, which can create bubbles or lift underlying paint.
5. Applying by Spraying:
   • For a flawless finish, thin the varnish with 10-20% distilled water.
   • Use a spray bottle, airbrush, or spray gun.
   • Apply 2-3 light mist coats from a distance of 25-30 cm, allowing each coat to dry between applications.
6. Drying & Recoating:
   • Lay the artwork flat to dry.
   • Allow the first coat to dry completely (approx. 1-2 hours).
   • For optimal protection, apply 2-3 thin coats. Light sanding with very fine sandpaper (600+ grit) between coats can achieve an ultra-smooth finish.
7. Clean Up: Clean all brushes, sprayers, and tools immediately with warm, soapy water.

Important Notes & Safety Information

• Always conduct a test on a sample or an inconspicuous area of your painting to ensure compatibility and the desired final effect.
• Apply only in a well-ventilated area with low humidity and no drafts to avoid dust settling on the wet surface.
• Store the bottle tightly sealed in a cool, dry place. Protect from freezing temperatures.
• Do not apply over oil-based paints, soft pastels, or graphite drawings without a proper isolating fixative.
