Protect floors and terraces with wood stain

What is a wood stain?

The stain is a fluid texture finishing product intended to protect porous materials such as wood or concrete. It is used indoors (furniture, paneling, floor ...) as outdoors (woodwork, garden furniture ...). Colorless or tinted, it penetrates the material while preserving its natural appearance.

It is non-film-forming, unlike varnishes and paints. Its composition makes it possible to preserve the appearance of the material, in particular the grain of the wood, and the moisture to circulate. Thus, the support breathes, avoiding chipping.

What is the difference between a stain and a varnish?

Wood stain is both a preventive treatment product (against fungi and insects) and a decoration product.

It permeates the wood and protects it with a microporous film which lets the support breathe. A varnishdecorates and protects the wood from external aggressions (sun, water, scratches ...) but forms an impermeable film. It is not a treatment product.

What does stain protect wood against?

Composed of antimycotic and insecticidal reagents, the stain protects the wood against external attacks: parasites (fungi, insects), the effects of light (preventing the wood from becoming gray) and humidity.

This is why it is used a lot for exterior joinery, which is particularly exposed. Attention: the stain protects but it is not curative.

What are the different types of stains?


There are different types of wood stain. It's up to you to choose which one suits your project!

  • Classic stains, colorless or stained, leave the wood visible. They are applied as an undercoat or as a finish.
  • High dry extract stains, which contain resins and active ingredients, coat the wood fiber very well and allow for less maintenance. The higher the dry extract, the longer the stain lasts.
  • The so-called "high protection" stains, rich in resins, are particularly suitable for protecting wood outdoors.
  • Impregnation stains act as an undercoat to facilitate the hanging of subsequent finishes.

How does a stain apply?

Apply a wood stain requires some technique and good tools.

Indeed, damaged, dirty or rotten wood does not absorb the stain correctly and the latter loses all its effectiveness. Hence the importance of preparing the support before applying the product.

For damaged, varnished or painted wood, it must be more or less stripped using a chemical stripper or a thermal stripper until the raw wood appears. Then smooth it with sandpaper.

If there are stains, then use a special wood lightening product. After dusting the support, apply the stain with a brush (or roller if it is a large area) in the direction of the wood grain. After drying (around 6 hours), apply a second coat. On young wood, even apply a third coat.

Can a stain also be decorative?

Yes, and there is a wide choice that allows you to play with the effects.

Transparent stains warm up the color of the wood and enhance its grain. Tinted stains (wood stains or colors) color the wood with a lot of naturalness. We even find some satin aspect. Finally, colored opaque stains soften the veining. They can unify the appearance, hide certain spots and hide application defects.

How long is a stain effective?

Stains qualified as "long lasting" serve as both protection and varnish. They can last up to four years. We are then content to clean the support well and to drain it before applying an additional layer.

How do you maintain a stain?

Not being film-forming, wood stain loses its satin appearance over time and forms a powder on the surface (it is said to "flour").

When the layer of stain begins to wear, simply sand it lightly on the surface with sandpaper and then apply one or two new layers of stain. This operation should be repeated approximately every two or three years.

For a new exotic wood, treated with an impregnation stain and then with a top coat, we can wait five years before renewing the stain.
