For the beginner painter, acrylic rock painting is great medium since it’s water-soluble, dries quickly, and is versatile. Acrylic, itself is a plastic polymer that can be painted on any surface as long as it’s not oily or waxy. Also, unlike oil-based paints, acrylics can be used devoid of any toxic solvents and can be easily cleaned with just soap and water, minimizing the messy outcomes of your work area.
A great feature with acrylic rock painting is that, if you make a mistake, you can just let it dry before painting over the dry part without destroying or having to repeat the artwork, it’s such a forgiving medium and well suited for beginners. It can be thinned with water to be used as a watercolor for transparent effects such as washes and glazes.
To begin with acrylic painting, you will need two things:
– Art supplies
– Creative ideas for what to paint
Acrylic Rock Painting Supplies
For starters, find an area with lots of natural light is best or a well-lit space to create your masterpiece.
Here are the supplies you’ll need:
- Acrylic Paint. Ensure you get the value for your money. It is better to consider the artist quality paint over the student quality paint as the hues are clearer and have less filler compared to the student ones. Overall, artist quality responds well to color and media mixing.
- Brushes. They should be of different shapes and sizes. The general rule is that big brushes act on larger areas and as such used in loose painting styles while the smaller ones are for painting details over small areas.
- Painting support. This can be a rock, canvas, board, paper, etc. Since acrylic paint works on many kinds of surfaces; you won’t be limited in your options for support.
- Water. Have water available when you want to clean your brushes off while switching from color to color when doing acrylic rock painting. Even better, have two sets, one to rinse and the other to dilute paints and moisten brushes.
- Cloth rag or paper towel. To act as an eraser and to dab off brushes after rinsing.
What is your Painting’s Focus?
The second step is deciding on what to paint. Look inwards or even outside, seek what you want to represent, or even your inspiration. Vividly discuss it, is it light, calm, aggressive? Once you decide, plan your composition around it, unless you are painting from an existing photograph, in which you don’t have to be 100% on the details.
Additionally, you can alter the sizes, colors and even position of the things to suit your goal. You can even edit, add and move objects around to balance your composition more. Plan your layout first; make some preliminary sketches for use as a reference.
Always Paint the Highlights Last
The last thing you need to do is to add the highlights. They don’t have to be white; all they need to be is of a lighter hue of the primary object’s color. It works out even better when you step back and observe your painting from a distance; you can evaluate it and take note of areas you need to tweak or improve.
