Brushes are an extremely important factor in achieving superior results from acrylics. Most brushes used for oil painting are also suitable for acrylics. If the paint is to be diluted and used like watercolor, a sable or synthetic soft hair brush is recommended to ensure smooth, soft strokes. Synthetic sable brushes are a better all-around choice because they’re more economical, softer and have a lighter touch than natural hair brushes. Synthetics are also easier to clean and will withstand the tough demands of acrylics.
