Liquid clear, often used in the Bob Ross wet-on-wet oil painting technique, is a medium that prepares your canvas for painting. It's applied after gesso has dried, creating a surface that allows for smooth blending of wet-on-wet oil paints.
Applying Liquid Clear: A Step-by-Step Guide
-
Prepare your canvas: Apply gesso to your canvas and allow it to dry completely. This provides a stable base for your painting.
-
Apply liquid clear: After the gesso is dry, apply a thin, even coat of liquid clear to the entire canvas. Avoid using too much, as this can lead to a sticky surface and difficulties with blending. Some artists recommend using a cheap sponge brush for application.
-
Let it dry slightly: Allow the liquid clear to dry slightly. It shouldn't be completely dry; a slightly tacky surface is ideal for the wet-on-wet technique. The drying time will vary depending on the type of liquid clear and environmental conditions.
-
Begin painting: Once the liquid clear is slightly tacky, start applying your oil paints. The liquid clear helps the paint to blend smoothly and allows for the signature wet-on-wet effect.
Alternatives to Commercial Liquid Clear
Some artists have found success using linseed oil as a substitute for commercially produced liquid clear. Linseed oil, when used sparingly, can provide similar blending properties. However, be mindful of using the correct amount, as too much can lead to issues with drying time and paint consistency. Experimentation may be necessary to achieve desired results.
Important Considerations
- Thin coats are key: Always apply liquid clear in thin, even coats. Too much liquid clear can make the surface too sticky and difficult to work with.
- Drying time varies: Drying times will depend on environmental conditions and the specific liquid clear used.
- Experimentation is encouraged: Different artists use different methods, and finding what works best for you requires experimentation.
