Mont Marte Acrylic Retarder, 75ml, Slow Drying Medium

Mont Marte Acrylic Retarder is a slow-drying medium designed to extend the open time of acrylic paints, making blending, gradients, and soft transitions easier. It helps you work with acrylics for longer before the paint dries, giving you more control during layering and glazing.

Capacity: 75ml. Slows drying to extend open time for blending and glazing. Improves workability by preventing paints from drying too quickly. Mixable with all acrylic paints. Maintains color vibrancy. Non-toxic and suitable for professional and student use.

Start with a small amount and test on a scrap swatch. A good starting ratio is 5–10% retarder by volume of paint, increasing gradually up to 15–20% if you need longer open time. Stir the mixture well on your palette and apply to your surface. Adjust as needed based on environmental conditions (temperature and humidity).

Yes. The retarder slows drying, which is ideal for glazing, feathering edges, and achieving smooth transitions between colors. It’s especially helpful for blending tones over a longer period before the paint sets.

The retarder is designed to preserve pigment vibrancy. When used in moderate amounts, it should not noticeably dull colors. Extremely high retarder ratios can affect opacity and drying behavior, so start with conservative amounts and test before larger applications.

It’s suitable for a wide range of acrylic applications, including canvas, paper, wood, and mixed-media surfaces. It works well with layering, detailed work, and glazing techniques where longer working time is beneficial.

Reseal the bottle tightly and store it in a cool, dry place away from direct sunlight. Keep it upright to prevent leaks and avoid exposure to extreme temperatures.

Yes. The retarder is non-toxic and suitable for professional and student use. As with any art medium, avoid contact with eyes, wash hands after use, and keep out of reach of children.

- Start with small amounts and test before full-scale use. - Avoid adding retarder to large batches of paint; mix fresh as needed. - Use separate palettes for retarder–heavy mixes to prevent over-concentration in a single area. - Monitor drying times; if it slows too much, reduce the retarder proportion or switch to a lighter glaze approach.
