A feature of acrylic paints is their high drying rate after being applied to canvas, paper or other surface. This quality is appreciated in many types of artwork. However, there are times when too fast thickening of the paint layer, on the contrary, is undesirable.

The use of a special composition, a drying retarder, can increase the fixing time of acrylic color.

Features of the

It may be necessary to slow down the drying of paint if you need to continue working with a certain layer, create overflows of shades on it, or work with halftones. In this case, the artist uses a shading technique that cannot be done with thick paint. Also, a change in the consistency and speed of drying of the color scheme is necessary when drawing shadows.

The composition, which slows down the thickening and drying of the applied layer of acrylic paint, is a transparent gel-like mass.

The main component of the retarder is glycol. It is a substance that retains moisture in acrylic paints.

Depending on the percentage of glycol in the retarding composition, the time for complete drying of the color layer can vary from half an hour to 4-5 hours… Also, the rate of thickening and drying of the color will vary depending on the ratio of acrylic paint to the thickener in which they were mixed.

When thinning acrylic color with water, the original tone is greatly distorted., and the consistency of the color becomes watery and inconvenient for application. The retarder does not distort the original color. When applied, the shade does not change or fade. Often, the color, on the contrary, acquires a better texture and becomes brighter.… Therefore, a slowing composition is often used in order to achieve a particular visual effect when drawing.

Terms of use

When working with a composition that slows down the drying of acrylic paints, you need to adhere to certain rules:

  • One way to use a retarder is to mix it with paint. To do this, about a quarter of the retarding compound (25% of the color by volume) must be mixed with acrylic paint. Mix the retarder and paint thoroughly. To do this, you can use a paintbrush or a wooden stick. With this ratio, a thin layer of acrylic color will dry completely in 30-40 minutes. Drying time for an average layer or 2-3 layers will be 2 hours.
  • The retardant can be used in a 1: 2 ratio (1 part retarder and 2 parts paint). The resulting composition will be more fluid and pliable when applied with a brush. Drying time for a thin layer of color will increase to 1 hour.

  • When mixing acrylic paints and a retardant in a 1: 1 ratio, you will get a mixture of the consistency of liquid sour cream. Such a composition cannot be used with some artistic techniques. Complete drying of the layer with this composition ratio will occur in 2 hours.
  • Do not mix paint with too much drying agent. If the amount of retarder exceeds the amount of color, this negatively affects the quality of the resulting solution. Bubbles form in the coloring composition, which interferes with its uniform application.

  • The optimal ratio of acrylic color and retardant is 1: ¼ (part of the paint and a quarter of the drying retardant). If these proportions are observed, the color properties are preserved, and the consistency of the finished mixture is optimal.
  • To create an artistic "haze" effect, in addition to the retardant composition, a small amount of water is added to the paint. Also, a similar composition is used to paint over the base or background. The addition of water allows the consistency of the color to be thinned, which allows the paint to cover a larger surface area. It is worth remembering that the use of water with a retarder will significantly increase the drying time of the layer.

Alternative method of application

Many artists are familiar with another way to use a retardant composition. In this case, the acrylic color is not mixed with the retarder.

  • A clean brush is moistened with a retarding compound. Then the desired color of a clean undiluted color scheme is taken on the brush.
  • Using the palette, paint and retarder are evenly distributed over the brush (for this, several strokes are made with the entire surface of the brush from bottom to top and from top to bottom). The palette can be replaced with a regular porcelain saucer.
  • After checking the color on the palette and distributing the compounds over the bristles, you can start applying the color.
