How to Naturally Protect a Wood Panel?

Whatever type of wood you have, to preserve it as long as possible, you will need to treat it. Whether it's indoor wood, or you wish to protect outdoor wood, factors like humidity and UV rays will become your main enemies. Let's discover together a natural solution and effective, to fight against the marks of time.

The different products for protecting wood

Before diving into the heart of the matter, a quick demystification is necessary!

Too many products are on the market and you don't know which one best suits your needs?

To answer this, ask yourself two questions: where and how frequently is your wood exposed to wear and tear?

Wood stain

Wood stain is a film-forming coating that preserves the texture of the wood while penetrating its interior. It will protect your wood from humidity, fungi, insects, and UV rays.

Designed primarily for outdoor use to protect against the weather, it is also used indoors on pieces subject to frequent wear, such as stairs for example.

Varnish

Just like wood stain, varnish is also film-forming but unlike the latter, it modifies the texture of the wood. By creating a smooth and shiny film on the surface, it offers robust protection against wear and humidity.

Oil

If you are looking for an ecological alternative to the two chemical agents mentioned previously, the next section should interest you.

It is important to note that wood stain and varnish require sanding of the wood beforehand, while applying oil only requires a simple cleaning.

Which oil to use to protect wood?

A natural oil for wood like linseed oil will be the perfect ally. Applied in a single coat or in several coats if necessary, as for a countertop for example, it penetrates and nourishes the wood while creating a protective barrier.

Linseed oil and its benefits for wood

Thanks to its extraction process, this oil retains properties beneficial to wood, such as:

protection against humidity
protection against UV rays
protection against insects
reduces dust deposits
makes the wood shine

This oil allows for numerous applications, it will be perfectly suited for MDF wood. For DIY enthusiasts concerned with detail, know that it also allows for creating an aged effect on solid wood panels.

Linseed oil and its risks for wood

As a single-component product that works with cellulose, the oil may slightly yellow your wood. To preserve the color of your wood panel, you can add a white pigment to your oil. Its concentration will depend on the desired result.

We tested it on a multiline beech wood panel:

The second risk concerns outdoor wood, which may darken over time. To remedy this inconvenience, there are products for de-graying that offer an almost instant result.

How to apply oil on a wood panel?

Step 1: Clean the wood panel

Clean your wood with very fine sandpaper (grit 150/180) to allow the oil to adhere well, then wipe with a cloth to remove any residue.

Step 2: Apply the oil

Brush on the oil with a paintbrush, making broad strokes while following the direction of the wood grain.

Step 3: Oil drying

Allow your wood to dry before applying a second coat. The drying time of linseed oil on wood varies depending on whether it contains an accelerator. If so, wait 20 minutes between coats. For the final drying, allow 12 to 24 hours.

Maintenance of oiled wood

Maintenance will depend on the wear of your wood as well as the number of coats applied. Ideally, repeat the operation every 6 months to 1 year, or even 2 years for well-maintained furniture.

Bonjour,
J'ai une table de salle à manger à poncer, je pensais plutôt mettre un vernis. Quel est le mieux, sachant que c'est notre table de repas au quotidien.
Merci

Pour protéger efficacement votre de table de salle à manger, il est possible d'appliquer un vernis de finition spécial contact alimentaire. Pour en être sûr et certain, le mieux serait de vous renseigner dans votre magasin de bricolage le plus proche !
Bonne et bricoleuse journée,
