Product essentials & how to use
Ciranova Reactive Stain is a premium, waterborne reactive wood stain designed to create authentic, aged finishes by chemically reacting with the natural tannins in wood. Ideal for achieving vintage, weathered looks on white oak, red oak and other tannin-rich woods like walnut, this stain penetrates deeply to highlight the wood's grain and texture without obscuring its natural beauty. Unlike traditional stains, it doesn't just sit on the surface—it interacts with the wood for a durable, non-fading color that evolves.
Always topcoat with a protective oil or varnish, such as Ciranova Hardwaxoil Magic, for enhanced durability and water resistance.
Whether you're refinishing furniture, cabinetry, or hardwood floors, Ciranova Reactive Stain delivers professional-grade aging effects that mimic years of natural patina in just one application.

-
01
Test the actual wood
Species, tannin content, grain, and sanding can materially change color and absorption.

02
Calculate the system
Confirm coverage, number of coats, hardener ratio, tools, and site conditions before ordering.

Follow technical data
Use the current preparation, application, drying, and maintenance instructions for the selected product.
THE COLOR DECISION
Choose the reaction, not just the color.
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.

WHY REACTIVE COLOR LOOKS DIFFERENT
Not Color on Wood. Color Created Within It.
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.

How Reactive Stains Work (and Why Wood Species Matters)
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.
Unmatched depth and character
No flat tones. No muddy overlays. Just real aging effects and complex undertones.
Key Features and Benefits
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.

One Stain. Endless Outcomes.
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.
FAQs
What are Ciranova Reactive Stains?
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.
How are reactive stains different from traditional stains?
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.
Will the color be identical on every wood species?
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.
Do knots, sapwood, filler, or glue lines stain differently?
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.
How do I apply Ciranova Reactive Stain?
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.
How do I avoid lap marks and overlaps?
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.
