Acrylic vs Gouache: Picking the Right Opaque Medium
Both dry opaque and both can be reworked — but they behave very differently once dry.
Acrylic dries permanently. Once a layer is dry, it's dry for good — you can paint over it, but you can't reactivate or blend back into it the way you can with gouache. That permanence is exactly why acrylic is the standard choice for paintings meant to last on canvas indefinitely.
Gouache stays reactivatable with water even after it dries, which makes it forgiving for illustration work — you can rewet a section and adjust it days later. This is also why gouache isn't typically varnished or framed the same way as a finished acrylic piece; it's more commonly used for illustration, design mockups, and studies.
Texture-wise, gouache dries matte and slightly chalky; acrylic can dry matte, satin, or glossy depending on the formulation and any added medium.
If you're illustrating and want to keep editing for days, go gouache. If you're painting something that needs to survive on a wall for decades, go acrylic.
