Understanding Viscosity Options with Liquitex Professional Acrylics

Making the correct art materials choices depends upon understanding the characteristics of the materials and how they best suit your artistic process and sensibilities.  In the Liquitex Professional colour range, it’s important to understand viscosity.

Viscosity can be understood as the thickness of the paint. For instance, Heavy Body is considered high viscosity meaning that it is quite thick like a gel. Soft Body is the original Liquitex acrylic paint range from when it was developed in 1955 and is considered low viscosity, more like a cream consistency. Acrylic Gouache is also low viscosity with a matte finish. Liquitex’s ultra fluid acrylic is Liquitex Ink, which would be considered very low viscosity, like water.

The most important thing to understand is that no matter the viscosity, each Liquitex Acrylic product uses the same high-quality professional-grade pigments. The difference is in whether the acrylic polymer binder mixed with the pigment to create paint is of thick or thin consistency. The thinner viscosity ranges like Soft Body, Acrylic Gouache and Ink are not watered down versions of Heavy Body. All the ranges are lightfast and compatible with Liquitex Mediums.



Liquitex Heavy Body


High viscosity, Liquitex Heavy Body is great for artists who want to achieve thick impasto brushstrokes and surface texture. Think of oil-like marks but with the versatility of acrylic.

Liquitex Soft Body


Low viscosity, Liquitex Soft Body is great for artists who want the same high-quality pigments found in Heavy Body with more ease of brushing for excellent coverage. Soft Body is a great choice for muralists.
