GOLDEN Extra Heavy Moulding Paste 946 ml jar — dense, sculptable texture that holds tool marks

GOLDEN Extra Heavy Moulding Paste is a dense, semi-opaque acrylic paste in a 32 fl. oz. jar designed to build pronounced texture, hold tool marks, and accept colour mixing for sculptural effects in painting.

This extra heavy moulding paste is part of GOLDEN's line of acrylic gels and pastes that range from fluid to sculptable. Formulated to dry slightly translucent and retain the impressions you press into it, the medium lets you add architectural texture, raised relief, or three-dimensional details to canvas, board, or mixed-media panels. It mixes predictably with acrylic colours and maintains stable body so you can create both subtle low-relief surfaces and bold impasto structures.

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

The dense formula adds real physical height and texture to a support, changing how light and shadow play across the surface. Because it holds tool marks, it preserves palette knife strokes, combing, and sculpted edges for expressive surfaces. When mixed with paint the paste accepts colour while keeping body; applied alone it dries to a slightly translucent, light-grey tone that can be glazed or painted over.

• Builds pronounced texture up to several millimeters or more per application.
• Holds crisp tool, knife, and brush marks for tactile surfaces.
• Mixes with acrylic colour without losing structural strength.
• Dries slightly translucent—suitable for glazing or overpainting.

What surfaces and supports can I use GOLDEN Extra Heavy Moulding Paste on?

Use this paste on rigid and semi-rigid supports prepared for acrylics, including stretched canvas, wood panels, Masonite, cradled panels, and primed board. For best results apply to a stiff support to prevent cracking; thin or flexible supports may need reinforcement. It also works as a ground for collage elements and mixed-media applications when allowed to dry thoroughly.

• Recommended on primed canvas, rigid panels, and wood supports.
• Accepts collage elements and adhesives when cured.
• Not ideal for unsupported, very flexible fabrics without reinforcement.
• Apply in multiple thin layers to build extreme heights safely.

How should I apply, finish, and paint over the paste?

Apply with a palette knife, trowel, brush, or any texturing tool; because it keeps tool marks, choose implements that create the shapes you want. Allow each layer to dry completely before adding more or before painting to avoid trapping moisture. Once cured, it accepts acrylic paints and mediums cleanly—use glazes for subtle colour shifts or opaque acrylics for full coverage.

• Apply straight from the jar with palette knives or texture tools.
• Dry time varies by thickness—allow full curing before overpainting.
• Sand lightly for softened edges or leave as-is for pronounced texture.
• Paint with acrylics or use glazes to alter translucency and hue.
