Utrecht Acrylic Gesso — White 473 ml, Medium-Viscosity Flexible Opaque Primer

This medium-viscosity gesso provides strong coverage, a slightly toothy surface for paint adhesion, and archival stability for long-lasting artwork. Formulated for artists, it balances flexibility and opacity so it can be used straight from the jar or thinned for washes. The white tint brightens colours and helps pigments show true; its consistency is thick enough to fill small imperfections yet workable for multiple coats.

How does this gesso affect paint handling and colour?

Priming with this gesso improves paint adhesion and gives pigments a consistent surface to sit on, reducing absorbency differences across supports. Because it's bright white and opaque, it preserves colour vibrancy and makes underpainting easier to see through translucent layers.

• Bright white base enhances colour luminosity and saturation.
• Medium viscosity prevents over-absorption of acrylics and oils.
• Creates a subtle tooth that helps acrylic, oil, and mixed-media layers grip.
• Multiple thin coats allow tuning of absorbency and texture.

How should I apply and prepare the surface?

Stir well before use and apply at room temperature. Use a flat brush, roller or palette knife; for very smooth boards sand lightly between coats. Allow each coat to dry fully before applying the next to avoid tackiness and ensure even coverage.

• Apply directly with brush, roller, or palette knife—no special tools required.
• Sand between coats for a smoother finish; for more tooth, use one coat only.
• Thin with a small amount of water to create washable grounds or translucent layers.
• Drying time varies with coat thickness—thin coats dry in a few hours at normal humidity.

What surfaces are compatible and how durable is the ground?

This gesso is formulated to adhere to canvas, primed and unprimed boards, panel, paper, and many mixed-media substrates. Once cured it remains flexible and resists cracking on most common artist supports when applied correctly in moderate layers.

• Suitable for stretched canvas, wood panels, illustration board, and heavyweight papers.
• Flexible film reduces risk of flaking and cracking on flexible supports.
• Archival-grade formula minimizes yellowing and degradation over time.
• Not a replacement for specialized primers for very slick or nonporous plastics without additional surface prep.

How much coverage will 16 oz provide and can I adjust texture?

A 16 oz (473 ml) jar covers roughly one to two small-to-medium canvases depending on how many coats and how thick they are. You can control texture by varying application tools, number of coats, and sanding between layers.

• Estimate: one medium-sized stretched canvas (18x24 in) with one to two light coats.
• Add texture with a palette knife or combing tool for impasto-friendly grounds.
• For ultra-smooth surfaces, apply multiple thin coats with light sanding between.
• Thinning with water decreases tooth and absorption for glazes and washes.

Who this is for: Utrecht Artists' Acrylic Gesso in 16 oz is aimed at painters, illustrators, and mixed-media artists who want a reliable, archival white ground that balances opacity with flexibility. It suits hobbyists priming small panels, students preparing study canvases, and professional artists seeking consistent coverage and paint adhesion without specialty primers.
