MONT MARTE Acrylic Colour Paint in Phthalo Blue delivers strong, versatile colour in a generous 250 mL (8.45 US fl oz) squeeze tube. The smooth, water‑based formulation offers good coverage and consistent viscosity for brush or knife work on canvas, paper, wood and more. It dries quickly to a durable acrylic film that can be layered, mixed with mediums or thinned with water for washes. Clean up hands and tools with soap and water while wet; allow to cure fully for best durability.
