Acrylic Washes And Pours

Those who love texture will appreciate the point of enhancing it with specially-mixed acrylic washes. Learning to make this mix was the first part of our class. While there are many recipes for it on Your Tube, we were aiming to mix something that could be used in a variety of materials such as paper, molding paste or canvas. Our surface was heavy watercolor paper because this paper can take a lot of abuse. We scored it, sanded it and covered it with masking fluid. The texture and hues on the wash can serve as a beautiful background for a collage. Once the acrylic washes were applied with a spray bottle, we tilted it and let the excess pour on a mixing tub that had an inch of water. The second part of our class was devoted to learning how to mix the paint for a pour. This time we tried bot...Read More

Impasto!

The third acrylics class was just like a food network show. We gathered round to see the making of modeling paste “recipes,” then we saw an impasto demonstration, and then it was time for us to try it for ourselves. Impasto is the application of thick paint to a surface. This can be done in a variety of ways with acrylic, thanks to the many applications of this medium and  to all of the additives in the market. We worked from simple references, mixing colors first on the palette, then applying the thick paste with a palette knife onto primed cardboard. People like impasto because it visually reminds viewers of the very physical nature of paint while simultaneously creating an illusion. It gives you the opportunity to work with paint that is easier to control. Application with a...Read More

Guide to Acrylic Mediums and Additives

Acrylic paints also come in a variety of consistencies, from liquid to heavy body. Simply put, mediums are the substances that maintain the integrity of your paint, while additives are the substances that alter the integrity of your paint. For more information, check out Golden or the Liquitex Resource Page. Acrylic mediums can change the consistency of your paint. They come all the way from pouring (liquid) consistency to heavy gel, which needs to be scooped out of the jar with a spatula. Gel or matte media are often mixed in with pigments to prevent or increase gloss while maintaining the flexibility of acrylic paint. This is why you should avoid adding water to increase transparency, because water increases the brittleness of hardened acrylic paint. Use water only to rinse your brushes....Read More
