Acrylic retarders are products used to slow down the drying time of the paint. They are added bit by bit to help painters achieve smoother blending, transitions, and overall better control over their painting process.

A paint retarder works by slowing down the evaporation of water or solvent in the paint, which extends the time that the paint stays wet and workable. This allows painters to manipulate and blend the paint on the painting surface for longer periods, without worrying about the paint drying too quickly.

They are used with acrylic paints that dry more quickly than the oil version, so it can be challenging to blend without the use of this. However, they can also be used with other types of colors, such as oil and watercolor.

It's important to note that too much retarder can negatively affect the quality of the paint and the final outcome of the painting. They should be added in small amounts to avoid any adverse effects on consistency, texture, and color.

Types of acrylic retardants

Brush Retarder
Airbrush Retarder

The main difference between them is the method of application. The first one is designed to be used with traditional brushes, while the second one is designed for use with airbrushes. Also, each product may have slightly different formulations and dilution ratios to suit their specific use.

Both products are designed to increase the drying and blending time of acrylic paints, but they may have slightly different formulations to suit their specific applications. For example, the Airbrush version may be more lightweight and have a lower viscosity than the Brush version, as it needs to be atomized and sprayed through an airbrush.

Additionally, the recommended dilution ratios for each product may vary. Airbrush Retarder may require a higher dilution ratio than Brush Retarder, as the airbrush applies paint in a much finer mist than a brush.

In conclusion, Acrylic Retarders are excellent products for hobbyists and painters who want to increase the drying and blending time of their acrylic paints. It's compatible with all acrylic paints and can help create smooth, blended effects on painting surfaces. However, it's essential to use them in moderation and follow the manufacturer's recommendations to avoid any adverse effects on the final painting result.
