Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion. Acrylic paints are water-soluble, but become water-resistant when dry. Depending on how much the paint is diluted with water, or modified with acrylic gels, media, or pastes, the finished acrylic painting can resemble a watercolor, a gouache or an oil painting, or have its own unique characteristics not attainable with other media. It is typically used by artists in mixed media paintings, as an underpainting for oil paintings, or as a final layer of color.
One of the challenges when working with acrylic paint is that it can be difficult to achieve certain effects because the paint dries so quickly. This is especially true when working with wet-on-wet techniques or trying to create a glazed effect. However, there are a few things you can do to slow down the drying time of acrylic paint and give yourself a little more working time.
One way to slow down the drying time of acrylic paint is to add a retarder to the paint. Retarders are available from art supply stores and online retailers. They are usually added to the paint at a ratio of about 2-3 drops per ounce of paint.
Another way to slow the drying time of acrylic paint is to mix the paint with an acrylic medium. Mediums are available from art supply stores and online retailers. They are usually added to the paint at a ratio of about 1 part medium to 2 parts paint.
If you want to add a retarder or medium to your paint but don’t want to change the color, you can add a clear acrylic glaze. Glazes are available from art supply stores and online retailers. They are usually added to the paint at a ratio of about 1 part glaze to 4 parts paint.
Adding a retarder, medium, or glaze to your paint will slow down the drying time, but it will also make the paint less opaque. If you want to keep the paint opaque but slow down the drying time, you can add a white acrylic paint to your palette. White acrylic paint is available from art supply stores and online retailers. It is usually added to the paint at a ratio of about 1 part white paint to 4 parts color paint.
One final way to slow the drying time of acrylic paint is to work in a humid environment. This can be achieved by using a humidifier or by placing a bowl of water next to your work area.
Acrylic paint dries quickly, but with a little planning and the right supplies, you can slow down the drying time and give yourself more time to work with the paint.
