Professional reactive color system

Professional wood finishing

Specify the whole system.

The final result depends on the wood, preparation, application, and compatible finishing system. Remove uncertainty before the full project.

  1. 01

    Test the actual wood

    Species, tannin content, grain, and sanding can materially change color and absorption.

  2. 02

    Calculate the system

    Confirm coverage, number of coats, hardener ratio, tools, and site conditions before ordering.

  3. 03

    Follow technical data

    Use the current preparation, application, drying, and maintenance instructions for the selected product.

Reactive Stain · Before & after

See how oak changes.

Reactive Stain develops color in tannin-rich wood such as oak. It needs a compatible protective finish. Test the full system on your project wood.

Reactive Stain application guide

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.

Preparation

Make sure that all old finish coats are completely removed and that the wood is free from dust and other dirt. Can be used on sanded, planed, and brushed wood. Pre-wetting the wood can reduce the risk of overlapping.

Application

Stir and shake well before and during use. Apply evenly reactive stain in the direction of the wood fiber, even out afterward. Reactive stain can be applied using a brush or spray gun and subsequently smoothened with a brush or mop.

Reactive stain can “pop” the grain so it is suggested that you smoothen the surface after the full reaction time with a buffing pad. Afterward, the surface should be made dust free, prior to finishing with an oil or waterborne finish from the Ciranova® product line. Please contact Ciranova® Technical Support for information about using a waterborne finish.

Protect

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

Maintain the completed surface with products and intervals appropriate to the final protective finish. Follow the maintenance guidance for the system used.

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.
