A
Quiet and natural
Restrained shifts that preserve a light, calm reading of the grain.
Professional reactive color system
Authentic color from within the wood
Creates aged depth by reacting with natural tannins—without masking the grain under a flat pigment layer.
Results vary by wood species and board. For a first project, test the 100 ml size on the exact wood you will finish.

Reactive Stain es un tinte reactivo envejecedor basado en colorantes naturales y reactivos. Reactive Stain está especialmente indicado para maderas envejecidas que contienen ácido tánico. Tras el tiempo de reacción, debe aplicarse inmediatamente un acabado al Reactive Stain con aceite o barniz.
—
» Reacciona con los taninos de la madera y le da un acabado único.
» Posibilidades ilimitadas en combinación con aceites con color.
» La intensidad del color puede ajustarse fácilmente con Reactive Stain Clear.
Asegúrese de eliminar completamente cualquier capa de acabado antigua y de que el suelo esté libre de polvo y otra suciedad. Puede usarse en madera lijada y cepillada. Prehumedecer la madera reduce el riesgo de solapamiento.
Remover y agitar bien antes de usar. Aplique una cantidad abundante de Reactive Stain en la dirección del grano de la madera, e iguale la superficie a continuación. Reactive Stain puede aplicarse con una brocha o espray, e igualarse posteriormente con una brocha o mopa.
Iguale la superficie con un disco con cepillo pasado el tiempo de reacción. A continuación, deberá eliminarse todo rastro de polvo de la superficie, tras lo cual puede dar un acabado a Reactive Stain con un aceite o barniz de la gama Ciranova®.

TEST BEFORE YOU COMMIT
Wood species, sanding, and light change every result. Test the color and sheen on your exact board before committing to the full project.
COMPLETE THE SYSTEM
Build color deliberately, then select the protection and maintenance system that preserves it.

TINTE REACTIVO
Professional wood finishing
The final result depends on the wood, preparation, application, and compatible finishing system. Remove uncertainty before the full project.
Species, tannin content, grain, and sanding can materially change color and absorption.
Confirm coverage, number of coats, hardener ratio, tools, and site conditions before ordering.
Use the current preparation, application, drying, and maintenance instructions for the selected product.
THE COLOR DECISION
Reactive color is shaped by the wood beneath it. Begin with the atmosphere you want, then test that direction on the exact species and preparation planned for the project.
Start with intent
A
Restrained shifts that preserve a light, calm reading of the grain.
B
Layered grey-brown character with an established, material presence.
C
Stronger reactions for tonal depth, contrast and a more expressive surface.

WHY REACTIVE COLOR LOOKS DIFFERENT
Reactive Stain works with natural tannins instead of masking the grain under a flat layer of pigment. The result is nuanced, dimensional and unique to the exact wood beneath it.

Two-stage finishing system
Reactive Stain creates the color; a compatible topcoat provides the protection. Follow these steps in order for a controlled, repeatable result.
Complete the color system with a compatible protective finish selected for the substrate and intended use. Follow the current Technical Data Sheet for the selected finish.
Maintain the completed surface with products and intervals appropriate to the final protective finish. Follow the maintenance guidance for the system used.

Reactive stains are not “regular stains.” Instead of simply coloring the wood by depositing pigment, reactive stains create color through a chemical reaction with what’s already inside the wood. That’s why they can look exceptionally natural and “in the grain,” and also why thesame stain can look different on different woods—and even on different boards of the same species.
No flat tones. No muddy overlays. Just real aging effects and complex undertones.
Natural Reaction for Authentic Aging
Reacts with wood tannins to produce unique, non-uniform colors that enhance grain patterns—perfect for rustic, antique, or modern distressed styles.
Customizable Intensity
Blend with Reactive Stain Clear to dilute and control depth, allowing for personalized shades on any project.
Versatile Application
Works best on oak but is suitable for other hardwoods; test on samples for optimal results on softer woods like pine.

Reactive Stain is only the beginning.
In this demo, we applied Reactive Stain Ash Grey to oak and allowed the chemical reaction to fully develop over 6 hours. The wood responded naturally — creating depth, movement, and tonal variation that pigment alone cannot achieve.
Then we changed only one variable: the topcoat.
We divided the same stained boards into four sections and applied four different Hardwax Oil colors.
Same wood. Same stain. Completely different outcomes.
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.
GUIDED SELECTION
Two decisions are enough to reach the right product family. Start with the surface, then choose the result.
Always test the complete system on your wood before the full application.
