Watercolor rock painting

Three ways to get a watercolor look on stone

Whichever you pick, the white acrylic base is what makes the colors glow. Bare grey stone absorbs and dulls a transparent wash.

Watercolor rock painting, step by step

1. Choose a smooth stone

   Smooth, flat stones take washes evenly. Wash and dry it fully.

2. Base coat white

   Two thin coats of white acrylic craft paint or a broad white paint pen. Let it dry overnight.

3. Lay the first wash

   Start with the lightest color. Brush on watercolor, or scribble a brush pen and pull it out with a damp brush.

4. Drop in a second color

   While the first is still damp, touch a second color at one edge and let it bleed. Do not scrub.

5. Dry completely

   At least an hour, longer on a cool day. A damp wash will lift under paint pens.

6. Add line work

   Draw outlines, leaves or lettering with an extra fine black or white paint pen.

7. Spray seal

   Two or three light coats of clear spray sealer. A brushed sealer will smear watercolor.

Watercolor ideas for rocks

• Floral wreath: a pale green wash ring with small pink blooms painted in the wash and leaves drawn on top.
• Galaxy wash: blue and violet wet into wet over white, then white star dots once dry.
• Ocean gradient: pale aqua at the top to deep blue at the bottom, with a white wave line.
• Rainbow blur: bands of color that bleed into each other, with a single word lettered on top.
• Botanical line art: a loose wash of one color behind a fine black drawing of a leaf or a fern.

Common watercolor rock problems

• Colors look grey: the base was not white enough, or the stone shows through. Add a second white coat.
• Paint pen lines lift the wash: the wash was still damp. Wait longer.
• Sealer smears everything: it was brushed on. Spray thin coats from a distance instead.
• Rock fades outside: watercolor and dye-based brush pens are not made for sunlight. Keep watercolor rocks indoors, or use thinned acrylic for outdoor ones.
