Amsterdam acrylic binder is a product with more than one function. You can use it as a glue for collage techniques as well as a primer for greatly absorbent grounds, such as walls and carton. Using a primer avoids the paint being ‘absorbed’. Acrylic binder is thick, liquid and milky white when wet, but colourless and transparent when dry. As an artist you can of course also mix your own colours. That, too, is something you can do with Amsterdam acrylic binder.
