Acrylic painting technique is a very versatile method of painting.
It's a water-based medium and the usual texture and consistency is similar to oil paints. It allows really heavy 3D effects. And you have the choice of either mixing the paints with the additives to create a solid color throughout the impasto, or letting the impasto dry, then painting over it.
All the brands and thicknesses can be thinned back down using water.
Acrylics, although similar in style and finish to oils, gives subtely different but important qualities to your work. Probably, its biggest benefit is its speed of drying.
