I have recently departed from the thick opaque painting style to experiment with layering transparent color. I started working on one in oil and one in acrylic, thinking that I would just work on the acrylic one while the oil was drying between layers. The oil painting is coming along, albeit slowly; however, I find myself coming up with any excuse possible to avoid working on the acrylic painting, while I wait, rather impatiently, for the oil to dry so that I can continue.
I am finding that the acrylic paint is drying way to quickly, sometimes to the point where if I lay one brush stroke down then return to my palette for a new color or more paint, the initial stroke is dry by the time I return. Similarly, I find myself having to mix large quantities of color if I want to be able to be able to have access to a shade for more than a single brush application. This method is either wasting a lot of my time remixing colors for each brush stroke or wastes a lot of my paint as I sacrifice it to allow for longer drying times. So basically, I am finding it nearly impossible to have a pleasant painting experience when I have to deal with paint drying within seconds on my canvas, palette, and brush if I am not watching. I did not have this problem with the opaque painting style.
I am using Liquitex Heavy Body paints with gloss gel medium which is supposed to extend drying time. I start by mixing my color, usually 5-10x the quantity I need, and adding medium to achieve the amount of transparency I want. Sometimes, if I feel I need a little more fluidity, I add a few drops of water to thin the mixture further.
Does anyone have any experience with this problem? Any solutions?
