The versatility of acrylics is built into the formulation of the paint, giving them excellent adhesion properties that allowing the paint to stick to surfaces from concrete to wood. Acrylics have the flexibility to move with the surface, expanding and contracting while still maintaining their integrity. Acrylics on canvas can even be loosely rolled up without affecting the finished film. Thinning with water allows watercolour techniques to be achieved without having to choose specially sized surfaces. Using the colour straight from the tube allows oil-like impasto marks to be created without the drawback of long drying times or worrying about “fat over lean” principles.
