Wooden furniture in a bathroom is subject to various daily aggressions linked to humidity: stagnant water, water vapour... Not all furniture is equally resistant to humidity. Their natural resistance depends on the type of wood chosen but also on the protection of the wooden furniture which has been made with a finishing product.
There are different classes of wood from 1 to 5. These classes represent the wood's resistance to moisture :
Class 1: Wood must be exposed to a moisture content of less than 20%.
Class 2: Wood may occasionally be subjected to a moisture content of more than 20%.
Class 3: Wood can be frequently subjected to humidity levels above 20%.
Class 4: in addition to being able to be subjected to a moisture content of more than 20%, class 4 wood may come into contact with fresh water.
Class 5: these are the most durable woods. They can be in contact even with salt water.
For bathroom furniture, class 1 woods are therefore to be avoided. Woods from classes 2 to 5 are suitable. Exotic woods (class 4 or 5) such as teak are particularly suitable for wood protection in a bathroom. Teak is particularly recommended for wooden vanity units which are particularly exposed to humidity and splashes of water. Higher class woods are naturally more resistant to moisture, but they must be protected to keep your wooden furniture in good condition for as long as possible.
If the wood is not protected, water will cause damage to the wood such as stains or deformation. In order to keep your wood in good condition, it is essential to protect your wooden furniture in a bathroom.
To avoid water-related deformation of the wood, the effective solution is to waterproof your wooden furniture to prevent water from penetrating. Several protection products can provide water-repellent protection for your bathroom furniture.
Within the Anova Bois range, we advise you to use varnishes for wooden furniture. These film-forming products will create a light film on the surface of the wood in order to make the wood resistant to external aggressions such as water and humidity.
For a damp room such as a wooden bathroom, we recommend the Worktop Varnish VPT500 from our range, which will provide reinforced protection against water. If your furniture has defects, we advise you to opt for a matt varnish which will hide the defects more than a glossy varnish. The varnishes in the Anova Bois range offer protection for wooden bathroom furniture while allowing the natural appearance of the wood to be preserved.
It is important to take precautions according to the nature of the wooden furniture in your bathroom :
If your furniture is made of tannic woods (oak, chestnut) or exotic woods (teak, ipe...), when applying any finishing product, tannins (chemical substances contained in some woods) can be released and cause yellow-black stains on your wood. To avoid these inconveniences, it is advisable to apply an Anti-Tanins Primer PAT400 from our range before applying a finishing product such as a varnish.
On all other wooden furniture in your bathroom, you can apply (before the wood varnish) a Pore Filler Primer such as Pore Filler Primer BP400 to strengthen the adhesion of the protective product and increase the protection of the wooden furniture against water and moisture.
To protect your wooden furniture, wooden bathroom varnishes are very easy to use products. They are applied in regular and thin layers in the direction of the wood fibres. You can consult the instructions for use of the varnishes here.
