Adding depth and texture to your paintings
If you like the texture of paintings that shows mounds and gullies of paint rather than the flatter surfaces typical of traditional tonal paintings, you may want to consider using modelling paste with your acrylics.
A similar product is available for oils, and is as easy to use. It is typically called impasto. Both of these products added to the paint will add a large amount of volume without taking away from the intensity of the colour. If it does change to another brand. Good quality ones which I have used are Winsor & Newton and Atelier.
