Paints & supplies
A painted rock might sit outside for months. Choosing gentle, non-toxic materials keeps it kind to whoever finds it - and to the soil, water and wildlife around it.
Paints
Water-based acrylics are the easiest choice, and non-toxic ranges are kindest for stones left in the natural environment. We like Natural Earth Paint’s acrylic paint, which is made to be safe and low-impact.
Varnish
A clear seal helps your message last and stops paint slowly washing into the ground. A natural, non-toxic varnish such as Natural Earth Paint’s natural varnish is a good match for eco-friendly paints. Let each layer dry fully before sealing, and varnish in a well-ventilated spot.
Pens for fine detail
For lettering and small details, water-based acrylic paint pens are much easier than a brush - and, being water-based, they’re non-toxic too. A set like these acrylic paint pens (affiliate link) works well for clean writing on stone.
A few gentle tips
- Start with a smooth, clean, dry stone - painting grips better.
- Build up in thin layers and let each dry, rather than one thick coat.
- Seal only once everything is completely dry.
- Avoid leaving freshly painted rocks near ponds, streams or the sea until they’re sealed and cured.
