Ciranova Reactive Stains are tannin-reactive stains that create color by chemically reacting with the natural tannins in wood, rather than simply depositing pigment like a conventional stain. This reaction helps produce nuanced, “in-the-wood” tones and depth.

Traditional stains mainly rely on pigments/dyes soaking into the wood. Reactive stains transform the wood’s chemistry, so the final look depends more on the wood species, tannin content, and surface prep. This is why reactive stains can look especially natural—but also more variable.

No. Because the stain reacts with tannins, species-to-species variation is normal. Even within the same species, boards can vary due to tannin levels, grain density, and mineral content. The pictures posted here were applied on european white oak.

Yes. Knots, sapwood, fillers, and glue areas can react and absorb differently, creating contrast. This is normal—and why testing on “real-world” boards matters.

Most users apply with a professional stain applicator, pad, brush, or microfiber method suited to the job size—then work it evenly to avoid overlaps. Always follow the product’s technical directions for your specific reactive stain.

Work in manageable sections.
Keep a wet edge.

Apply consistently (same tool, same pressure, same pace).

Avoid stopping mid-board or mid-field when possible.

Maintain consistent lighting so you can see wet edges.
