Step-by-Step Instructions

Step 1: Prepare the white base

Wash and dry your rock. If the rock is not naturally pale, paint the entire surface white and let it dry completely. The white base is crucial — it reflects light back through the translucent paint layers exactly as watercolor paper does, creating the characteristic luminous glow of watercolor painting.

Step 2: Mix watered-down paints

Dilute each acrylic paint color with water to create very thin, transparent washes. The paint should be so thin you can almost see through it. Test on paper first — the color should leave a translucent tint, not a solid opaque layer. This dilution is the key to the watercolor effect.

Step 3: Apply wet-on-wet washes

Wet the entire rock surface with clean water using your large brush. While still wet, drop or brush on large areas of color — teal in one area, pink in another, purple in another. The colors will bleed and blend into each other naturally at the wet edges, creating soft transitions like real watercolors.

Step 4: Add detail layers when dry

Let the first wash dry completely. Then apply a second, slightly more concentrated wash of color in the center of each color area to deepen it. You can add small painted details: simple flowers, stars, leaves, or abstract shapes using a fine brush and more concentrated paint over the watercolor wash.

Step 5: Add white details and seal

Using concentrated white paint and a fine brush, add small botanical details: tiny dots, simple leaf shapes, or a few small flowers over the colorful background. These white elements stand out beautifully against the soft washed colors. Apply clear sealant when dry.

Step 6: Add RoxGeo Code

On the bottom or back of your rock, write ROXGEO.COM followed by a slash and your rock’s unique code (e.g. ROXGEO.COM/ABC123). This lets the finder go directly to your rock’s profile page and log their discovery. If the rock is too small for the full address, write #ROX followed by the code without spaces (e.g. #ROXABC123) — it’s short, easy to search on Google, and leads straight to your rock’s journey page. Use a fine-tip permanent marker or acrylic paint pen, and seal it with clear varnish so the code stays readable through rain, sun, and adventure.

Helpful Tips

Wet the entire rock surface before applying colors for the most beautiful wet-on-wet blending.
Heavily diluted paint (almost water) is the secret to the watercolor look on a rock.
Allow colors to bleed and mix naturally at the edges — forced blending looks less organic.
White botanical details over the colorful wash look stunning and add a finished, artistic quality.
This is a very forgiving technique — imperfections create unique, natural-looking results.
For the RoxGeo code on the bottom, use a waterproof permanent marker (like Sharpie) or an acrylic paint pen. Apply 2–3 coats of clear sealant over the code — this keeps it readable through rain, sun, and handling for months.
Writing #ROXCODE (e.g. #ROXABC123) on your rock makes it easy to find via Google search. We actively optimize for this hashtag, so anyone who searches for it will find your rock’s profile page quickly.
The full address ROXGEO.COM/CODE takes the finder directly to your rock’s card, where they can see its full travel history, previous finders, and photos from every stop on its journey.
