GOLDEN Extra Heavy Moulding Paste — 237 ml light-grey sculptable acrylic medium that holds tool marks

GOLDEN Extra Heavy Moulding Paste is a sculptable, semi-opaque acrylic paste that builds durable texture, holds tool marks, and mixes cleanly with colour for three-dimensional surfaces.

Extra Heavy Moulding Paste from GOLDEN is designed for artists who want pronounced relief and lasting dimensional structure on their supports. This light-grey, semi-opaque medium dries to a slightly translucent finish, accepts pigment well, and can be applied thickly without sagging. Use it on canvas, board, or prepared panels to create ridges, impasto effects, and architectural textures that remain stable when dry.

How will this paste change the look and feel of my paintings?

When incorporated into a work, Extra Heavy Moulding Paste adds real, tactile depth rather than just an illusion of texture. It retains marks from knives, combs, brushes, and other tools so surface gestures stay visible after drying. The paste’s slight translucency also allows layered glazing and colour mixing to read differently depending on thickness.

• Creates raised relief and impasto that refracts light across the surface
• Holds crisp tool edges and sculpted details without collapsing
• Mixes with acrylic colour for integrated textured passages

Can I colour or blend this moulding paste with my paints?

Yes—this paste mixes cleanly with acrylic colours so you can integrate pigment before or after application. Add paint directly into the paste for unified coloured texture, or apply colour washes and glazes over dried passages for subtle depth and tonality. Avoid excessive amounts of solvent; use acrylics and compatible flow aids for predictable results.

• Pre-mix with acrylic pigments for consistent coloured texture
• Paint over dried paste with acrylics, glazes, and mediums
• Maintain surface integrity by using water-based additives designed for acrylic systems

What surfaces and techniques are best suited to this medium?

Extra Heavy Moulding Paste performs best on rigid or well-primed supports that can carry added weight and dimensional detail. It bonds well to gessoed canvas, wood panels, Masonite, and archival boards. Popular techniques include palette-knife sculpting, combing, stencil work, and building layered reliefs that can be sanded or carved once thoroughly dry.

• Ideal for gessoed canvas, panels, and rigid supports
• Techniques: palette knife, carving, stenciling, and additive layering
• Can be sanded or shaped after full cure for refined surfaces

How durable is the finished surface and what are the handling tips?

Once fully cured, GOLDEN Extra Heavy Moulding Paste produces a stable, durable surface that resists cracking when used properly. Allow ample drying time for thick applications—drying time increases with thickness and environmental humidity. Store containers tightly sealed and work in moderate temperatures to preserve consistency.

• Dries to a slightly translucent, stable film; avoid extreme thickness without staged drying
• Allow extended curing for deep sections to prevent surface skinning over
• Store sealed, in a cool, dry place to maintain workability

Who is this for: GOLDEN Extra Heavy Moulding Paste is aimed at professional and advanced amateur painters, mixed-media artists, and sculptural painters who need a reliable heavy-bodied medium for building long-lasting texture. If you want to create defined impasto, architectural relief, or sculptural layers that take paint well and survive framing and handling, this paste provides a consistent, artist-grade solution made in the USA by a company with decades of paint-making experience.
