Be on the lookout for the ideal shape stone to serve as your canvas if you have a specific design in mind, such as a cat, owl, or caterpillar. A fun part of the process is looking for the ideal stone.

Make sure you have permission to take the stones before collecting them from nature. State and national parks forbid their removal.

You should make sure your canvas is spotless if you picked it up from the outdoors. Use some soap and warm water to clean it off, then pat it dry. Even an old toothbrush would work well to scrub it.

Some stones have textured areas that will make painting them a little more challenging. You can use sandpaper to remove the patch by beginning with 100 grit and working your way up to 150 and 220 grit.

You are now prepared to sketch your design onto the rock. To make your design perfect, it might be a good idea to try practicing it first on a piece of paper. You can use a pencil, chalk, or soapstone to etch your image into the rock.

Start painting now! Move slowly, starting with the largest elements of the design and working your way down, letting each coat dry completely before continuing. To help the paint dry more quickly, use a hairdryer.

It’s time to seal your design after you’ve finished painting it! To ensure that your art lasts for a long time, seal it with a sealer and apply one or more coats.

Rock Preparation for Painting

In a bucket, wash stones with soap and water. Scrub the dirt away with an old toothbrush or scrub brush. Allow stones to air dry completely after drying with a towel or paper towel.

With sandpaper, remove any gritty parts and buff any polished rocks.

Before priming, smooth wood filler over any holes, dimples, or cracks in the rock.

You can also add wood filler to the base of a stone to help it stand on its own.

Apply a coat or two of acrylic gesso or primer to your dry and clean stone. If the rock is dark, this will help subsequent layers of paint adhere to the surface and make the colors appear brighter.

When the primer has dried, you can begin painting and decorating your rock.

Clean up, wash your brushes thoroughly with soap and water, replace the tops on the acrylic paints to keep them from drying out, and you’re ready for the next time!

What About A Background For Painting Rocks?

Use two coats of paint and let the first coat completely dry before applying the second if you want to paint a background on your stone. After the second coat of paint has dried, you can begin creating your actual “picture.” You need to be patient! Naturally, young children don’t, so you can just allow them to begin painting on the stone.

For a really cool appearance, some people like to paint a white background on a dark stone. The appearance of a black background is also very intriguing. Just make sure to paint your image with a vivid color, like bright yellow, on top.
