Paint Additives

Angelus Brand Paint Additives let you modify how Angelus Acrylic Leather Paint flows, dries, and sets, without losing color, adhesion, or flexibility. This collection brings together every additive you need to dial in the exact behavior your project demands: 2-Thin Paint Thinner for airbrush spraying and smoother brush flow, 2-Thick Paint Thickener for impasto and textured strokes, 2-Soft Fabric Medium and Golden GAC-900 to keep paint flexible on denim, cotton and canvas, 2-Hard Film Hardener and Golden GAC-200 for rigid substrates like wood, plastic and ceramic, and Duller for knocking gloss paint down to a flat matte finish. Angelus 2-series additives are available in 1 oz, 4 oz, pint, and quart sizes (Duller and 2-Thin run the full range; 2-Hard ships in 1 oz, 4 oz, and pint), while Golden GAC-900 and GAC-200 come in 8 oz bottles. Together, they cover leather, vinyl, canvas, denim, cotton, nylon mesh, wood, and plastic.

Mix any additive directly into Angelus Acrylic Leather Paint before applying. Start with small ratios, typically 10–25% additive to paint, stir thoroughly, then test on a scrap piece of the same material to fine-tune the effect. Formulated specifically to work with Angelus paint, these additives preserve vibrant color, strong adhesion, and the flex you need so your finished project doesn't crack, peel, or rub off.

Angelus Paint Additives are built to extend what one bottle of Angelus Acrylic Leather Paint can do. Here are the most common ways customizers, leather artists, and apparel painters put them to work:

• Thinning Paint for Airbrush Spraying: 2-Thin Paint Thinner reduces viscosity, so Angelus paint flows cleanly through an airbrush without clogging or losing pigment density. It's essential for fades, gradients, and fine detail work on sneakers, jackets, and canvas.
• Adding Body and Texture with a Thickener: 2-Thick Paint Thickener builds Angelus paint up to a heavier consistency, perfect for impasto strokes, palette knife work, and raised 3D effects on leather, canvas, and mixed-media art.
• Painting Fabric Without Stiffening It: 2-Soft Fabric Medium and Golden GAC-900 keep paint soft and flexible on denim, cotton, canvas, and other fabrics, so painted garments and canvas sneakers stay comfortable and move naturally instead of feeling cardboard-stiff.
• Painting Rigid Substrates: 2-Hard Film Hardener and Golden GAC-200 boost paint hardness and adhesion on rigid surfaces like wood, plastic, ceramic, and hardware, where flexibility isn't needed, and a tougher, more durable film is the priority.
• Knocking Down Gloss for a Matte Finish: Duller reduces the natural sheen of Angelus paint, letting you turn glossy colors into flat matte tones without changing the color itself, ideal for tactical looks, leather restoration matching, and stealth-style customs.
• Custom Sneaker Projects with Mixed Materials: One shoe often combines leather, mesh, suede, and rubber. Additives let you tune the same paint differently for each part, softer for the mesh tongue, harder for the midsole, without switching paint lines.
