Watercolor paint overview
Watercolor is a water-based art paint traditionally used in transparent washes on absorbent watercolor paper. Specialized watercolor grounds can also prepare materials such as primed canvas and wood, but their feel and finished appearance differ from paper.
Watercolor paint compatibility
Watercolor paper is the standard surface. Use a watercolor-specific preparation when painting another material, and test how the prepared surface absorbs and releases color.
| Surface | Compatibility | Preparation | Primer or ground | Finish | Guide |
|---|---|---|---|---|---|
| Paper | Excellent on watercolor paper | Choose paper with enough weight and sizing for the amount of water; stretch lighter sheets when needed to reduce buckling. | Usually not required on watercolor paper. | Normally displayed behind glazing rather than varnished. | — |
| Canvas | Good with watercolor-specific preparation | Start with clean, dry, primed canvas and follow the preparation product's coating and drying directions. | Apply a watercolor ground or multi-surface watercolor preparation. | Protect from moisture and abrasion using a display method suited to watercolor. | — |
| Wood | Good with watercolor-specific preparation | Use clean, dry, stable wood and smooth rough areas before applying the preparation. | Apply a watercolor ground or multi-surface watercolor preparation. | Protect from moisture and handling using a method compatible with the preparation and paint. | — |
