Understanding Oil Paints: The Bob Ross Standard

Oil paints, the traditional choice for masters throughout history, are known for their slow drying time, rich colors, and blendability. Bob Ross famously used oil paints in his “Joy of Painting” series, employing the wet-on-wet (alla prima) technique, which involves applying paint onto a wet canvas, allowing for seamless blending and the creation of soft, atmospheric effects. This technique is particularly well-suited for landscapes, as it allows for the effortless rendering of clouds, trees, and water.

The Composition of Oil Paints

Oil paints consist of pigment suspended in a drying oil, typically linseed oil. The oil acts as a binder, holding the pigment particles together and allowing them to adhere to the canvas. The drying process involves oxidation, where the oil absorbs oxygen from the air and hardens, forming a durable paint film. The slow drying time of oil paints is due to the gradual nature of this oxidation process.

Advantages of Oil Paints

Blendability: Oil paints offer unparalleled blendability, allowing for smooth transitions and subtle gradations of color. This makes them ideal for creating realistic effects and capturing the nuances of light and shadow.
Slow Drying Time: While some consider it a disadvantage, the slow drying time of oil paints allows for extended working time. Artists can blend, adjust, and rework their paintings over several hours or even days. This is crucial for the wet-on-wet technique.
Rich Colors: Oil paints are known for their rich, vibrant colors. The high pigment concentration and the refractive properties of the oil binder contribute to the depth and luminosity of the colors.
Durability: Oil paintings are highly durable and can last for centuries with proper care. The oil paint film is resistant to cracking, fading, and yellowing.

Disadvantages of Oil Paints

Slow Drying Time: The slow drying time can be a disadvantage for artists who prefer to work quickly or who need to complete a painting in a limited amount of time.
Clean-up: Cleaning up oil paints requires solvents such as turpentine or mineral spirits, which can be messy and potentially harmful.
Cost: Oil paints and related materials (solvents, mediums, brushes) can be more expensive than acrylics.
Ventilation: Working with oil paints requires good ventilation due to the fumes emitted by solvents.

Exploring Acrylic Paints: A Modern Alternative

Acrylic paints are a relatively recent invention, gaining popularity in the mid-20th century. They consist of pigment suspended in an acrylic polymer emulsion. Unlike oil paints, acrylics are water-based, making them easier to clean up and faster to dry. While Bob Ross primarily used oils, acrylics offer a viable alternative for artists seeking a quicker, more convenient medium.

The Composition of Acrylic Paints

Acrylic paints are composed of pigment particles dispersed in an acrylic polymer emulsion. This emulsion is essentially a suspension of tiny acrylic particles in water. As the water evaporates, the acrylic particles coalesce, forming a flexible and durable paint film. The rapid evaporation of water is what gives acrylics their fast drying time.

Advantages of Acrylic Paints

Fast Drying Time: Acrylics dry much faster than oil paints, typically within minutes or hours. This allows artists to layer paint quickly and complete paintings in a shorter amount of time.
Easy Clean-up: Acrylic paints can be cleaned up with water, making them a convenient and environmentally friendly option.
Versatility: Acrylics can be used on a wide variety of surfaces, including canvas, paper, wood, and fabric.
Cost-Effective: Acrylic paints and related materials are generally less expensive than oil paints.

Disadvantages of Acrylic Paints

Fast Drying Time: The fast drying time can be a disadvantage for artists who prefer to blend their paints extensively. Once acrylics dry, they become permanent and cannot be easily reworked.
Less Blendability: Acrylics are not as easily blended as oil paints, requiring the use of special mediums to achieve smooth transitions.
Color Shift: Some acrylic paints can experience a slight color shift as they dry, becoming slightly darker or lighter.
Less Forgiving: Mistakes are harder to correct with acrylics due to their quick-drying nature.

Achieving the Bob Ross Look with Acrylics: Techniques and Considerations

While Bob Ross is synonymous with oil paints, it is possible to achieve a similar look and feel using acrylics, albeit with some adjustments to technique and materials. The key is to mimic the blendability and working time of oil paints as closely as possible.

Using Retarders and Wetting Agents

Acrylic retarders are mediums that slow down the drying time of acrylic paints, giving you more time to blend and manipulate the paint. Wetting agents can also be added to acrylics to improve their flow and blendability. These mediums are essential for replicating the wet-on-wet technique with acrylics.

Working in Thin Layers

Instead of applying thick layers of paint as Bob Ross did with oils, it’s best to work in thin layers with acrylics. This allows the paint to dry more evenly and prevents cracking. You can also use a spray bottle to mist the canvas with water, keeping the paint moist and workable for longer.

Choosing the Right Brushes

Stiff, natural-bristle brushes, similar to those used by Bob Ross, are ideal for applying acrylics. These brushes hold a lot of paint and allow for controlled application. Synthetic brushes can also be used, but they may not be as effective at blending.

Experimenting with Textures

Acrylics can be used to create a variety of textures, from smooth and glossy to rough and matte. By adding texture mediums to your acrylic paints, you can create impasto effects similar to those achieved with oil paints. According to numerous artists, heavy body acrylics work best for mimicking oil painting techniques.

Natural bristle brushes are better suited for oils, while synthetic brushes are ideal for acrylics. Using separate sets ensures the longevity and performance of your brushes.
Question: What’s the best way to clean oil paint brushes?

Answer: First, wipe off excess paint with a cloth or paper towel. Then, rinse the brush in a solvent like turpentine or mineral spirits. Gently massage the bristles to remove all traces of paint. Finally, wash the brush with soap and water and allow it to dry completely.
Question: How do I prevent acrylic paints from drying too quickly?

Answer: Use a retarder medium to slow down the drying time. You can also mist the canvas with water to keep the paint moist. Working in a humid environment can also help. Consider using a stay-wet palette.
Question: What’s the difference between student-grade and professional-grade paints?

Answer: Professional-grade paints have a higher pigment concentration, resulting in richer, more vibrant colors. They are also more lightfast, meaning they are less likely to fade over time. Student-grade paints are less expensive but may not offer the same level of quality.
Question: Can I paint over an oil painting with acrylics?

Answer: No, it’s generally not recommended to paint over an oil painting with acrylics. Acrylics are water-based and will not adhere properly to the oily surface. The acrylics may eventually peel or flake off.
Question: What is “fat over lean” and why is it important in oil painting?

Answer: “Fat over lean” refers to the principle of applying layers of oil paint with progressively more oil content. The initial layers should be “lean” (containing less oil) and the subsequent layers should be “fat” (containing more oil). This helps to prevent cracking and ensure the longevity of the painting.
Question: How do I dispose of used solvents safely?

Answer: Never pour used solvents down the drain. Instead, allow the paint solids to settle to the bottom of the container. Then, carefully pour the clear solvent into a separate container for reuse. Dispose of the paint solids and any remaining solvent at a hazardous waste disposal facility.
Question: What are some common mistakes beginners make when using oil paints?

Answer: Common mistakes include using too much solvent, applying paint too thickly, and not following the “fat over lean” rule. Beginners may also struggle with blending and color mixing.
Question: Is it possible to create impasto effects with acrylics?

Answer: Yes, you can create impasto effects with acrylics by using heavy-body acrylic paints and texture mediums. These mediums add thickness and body to the paint, allowing you to create raised textures and bold brushstrokes.
Question: How do I varnish an oil painting?

Answer: Allow the oil painting to dry completely for at least six months before varnishing. Clean the surface of the painting with a soft cloth. Then, apply a thin, even coat of varnish using a soft brush. Allow the varnish to dry completely before handling the painting. Use a removable varnish, so it can be cleaned or reapplied in the future.
