How to Incorporate Flow Aids In Paintings as a Hobbyist
Flow aids are solutions that improve the quality of paintwork by increasing the viscosity of water-based paints. They increase both the flow and absorption rate of paints. By increasing the drying time of the paint, they also give the artist time to manipulate paint on the canvas and achieve desired effects. However, inexperienced artists or hobbyists might not have the know-how to manage this critical aspect of painting. To this end, here are a few tips on how to incorporate them in your painting:
- Use When Diluted – The flow aid is usually a concentrate that needs to be diluted in water before mixing with paint. Using it undiluted causes the paint not to stick to the surface. Liquitex recommends one part flow aid to ten parts water. The artist is free to add more water if the smoothness or flow of the paint is not as required. The solution can then be used to thin the paint.
- Use Distilled Water – Distilled water is recommended for dilution since the chemical composition of tap water varies depending on the source. These variations may affect the reaction of the flow aid with the paint. Use of distilled water should be observed even when not using flow aid for a more uniform painting.
- Dip Brush Into Flow Aid - It is recommended to dip the paintbrush in the flow aid before the work starts. Dipping will ensure that the paint does not stick to the brush. It also helps dissolve any paint that may have previously dried on the bristles. Every stroke of the brush will then leave a uniform mark on the canvas. Always place the brush in the solution when taking a break.
- Drop a Spot on the Painting – Sometimes paint will dry on the canvas before the artist has finished an impression. Placing a drop on the subject area will re-dissolve the paint and allow work to resume on the affected section. Doing this also allows the artist to change or recolor regions that had already set.
Flow aids can be used on a variety of painting surfaces, such as canvas, concrete wall, paper, or wooden board. Their use has been shown to improve the texture and overall look of the work. Note that they are ONLY useful for water-based paints. Mixing with oil-based paints might not achieve the desired effects. Try them in your painting and you may soon have a masterpiece in the National Gallery of Australia.
