⚡ At a Glance
  • Finish Quality: Crystal-clear high-gloss finish with strong surface adhesion
  • Best for: Hobbyists and professional artists sealing air-dry clay and mixed-media pieces
  • Not ideal for: Large outdoor items subject to continuous weather exposure

Forms a hard protective film that delivers waterproof performance and helps prevent yellowing. Suitable for clay, ceramics, wood and mixed media and supplied with two small brushes for accurate application.


Waterproof, crack-resistant protection - thanks to strong adhesion forming a hard protective film

High-adhesion varnish cures to a solid, continuous film on the surface, creating a barrier against moisture. The film reduces the chance of mould or cracking after water exposure by keeping water from penetrating the clay matrix.

Artwork remains stable after occasional contact with water, reducing surface damage and structural cracking. Ideal for pieces that may be handled or mildly splashed.

High-gloss, long-lasting clarity - with crystal-clear varnish that resists yellowing

Gloss formulation dries into a transparent layer that retains optical clarity rather than turning amber over time. Anti-yellowing properties come from the varnish chemistry that resists discolouration as it sets.

Finished pieces look professional and colour-accurate for longer, keeping paint and natural tones vivid. Suitable where presentation and colour fidelity matter.

Precise, tidy application - with two small brushes included for detail work

Two small brushes allow controlled brush strokes and access to tight gaps and edges, reducing over-application. Brush sizes match delicate craft surfaces for an even protective coat.

Saves time sourcing extra tools and makes sealing fine details straightforward, helping avoid drips and heavy buildup. Great for small sculptures and intricate mixed-media pieces.
