Why should you impregnate wood?

The impregnation / waterproofing / proofing of wood is primarily used as a preventative measure to protect the material. The aim of applying the additional protective layer is not only to create greater resistance to weather influences, but also to ward off moisture ingress and many other unwanted intruders.

The impregnation applied to the wood fibers creates a deep protection that also preserves the appearance of the wood and increases its service life.

The invisible impregnation, which is based on state-of-the-art nanotechnology, creates a protective barrier against water, dirt and oil while preserving the natural texture of the wood. The application of Nanoflex® Barrier can even protect against graffiti.

The advantages of our wood impregnation / wood treatment

The impregnation / waterproofing / proofing of exterior wood offers numerous advantages that significantly extend the service life and beauty of the wood; you will find a list of these below:

Comprehensive protection	Because the impregnation penetrates into the wood fibers, it does more than just protect the surface. The impregnation seals the entire material, making it significantly more robust against external influences of all kinds.
Water repellent	The applied protective layer forms an invisible barrier against the penetration of liquids. This massively inhibits the formation of mold due to moisture and thus also visibly slows down the ageing of the material.
Weather resistant	Thanks to its smooth and robust protective layer, the impregnation not only protects against unwanted liquids, but also against other weather conditions or external influences such as moisture and unwanted deposits.
Breathable	Despite the water-repellent properties of the impregnation, the applied coating is highly breathable; the resulting water vapor exchange additionally strengthens the function against mold growth and the material can breathe.
Optician retention	The thinly applied protective layer has a dirt-repellent effect for a new look in the long term; it also emphasizes the natural grain of the wood.
Durable	Compared to conventional wood preservatives, Nano-Care® sealing solutions require little maintenance. The protection is particularly long-lasting and the impregnation needs to be refreshed much less frequently.
Environmentally friendly	Our solvent-free sealing solutions are harmless to people and the environment, yet are just as effective.
Easy to use		The impregnation of wood with our ready-to-use impregnation solutions is extremely easy to apply, even for home use. Moreover, special equipment is not required for brush or spray application.

Areas of application

Our impregnation products tailored to wood are widely used in various areas; here are a few examples:

Wood impregnation / wood treatment for outdoor use – e.g. for terraces, garden furniture, fences, pergolas or even façade cladding.

Wood impregnation / wood treatment for interior use – e.g. for wooden floors, furniture, stairs, wall paneling or doors.

Or also in building and construction, public areas or art and decoration, e.g. for roof trusses, wooden houses, bridges, carports, playgrounds, park benches, outdoor cladding, wooden decks, sculptures, garden ornaments, decorative wooden elements, etc.

Which types of wood can be protected by impregnation / waterproofing / proofing?

In addition to the large number of application areas, there are hardly any restrictions on the types of wood for Nano-Care® wood impregnation products; we have suitable impregnation solutions for almost all types of wood, including spruce, pine, fir, larch, Douglas fir, oak, robinia, beech, maple and ash.

The choice of suitable wood impregnation depends on the resin content. For example, teak, oak and robinia are naturally more resistant to moisture and rot, which is why they require less impregnation / waterproofing / proofing. Other woods with a lower resin content, such as spruce, fir or pine, on the other hand, require more intensive impregnation to protect them adequately.

The technology of wood impregnation / wood treatment

Applying the impregnation by brush or spray application is the most common and also the easiest method of wood impregnation. However, there are also other ways of applying a coating that penetrates the material:

Wood impregnation / wood treatment by dipping	Wood is immersed in a vat of wood preservative Penetration depth of a few millimeters Requires longer exposure time Mainly used in the professional sector Uneconomical for small quantities
Impregnation / waterproofing / proofing by hot-cold impregnation	Wood is alternately immersed in hot and cold wood preservative Penetration depth of approx. 30 to 50 mm Good for woods that need deep impregnation / waterproofing / proofing
Impregnation / waterproofing / proofing using the osmosis process	Paste-like wood preservative applied to undried wood Wood is covered and stored for up to 3 months Ensures good impregnation / waterproofing / proofing inside Particularly suitable for hard-to-reach wood joints
Impregnation by pressure treatment / pressure impregnation (KDI)	Wood preservative is pressed into the wood under high pressure Uniform impregnation / waterproofing / proofing throughout the wood Especially for heavily used wood in outdoor areas Not suitable for all types of wood (e.g. larch or Douglas fir)
Boiler vacuum pressure impregnation (KVD)	Pressure treatment / pressure impregnation with additional vacuum Enables the highest penetration depth For particularly heavily stressed woods, such as in shipbuilding Very complex and expensive

The most advantageous wood impregnation process for a particular situation depends on various factors such as the type of wood, the desired level of protection and the intended use of the material. It is therefore advisable to seek advice from an expert.

Instructions: Work steps for wood impregnation / wood treatment

The application of our wood impregnations for private use Nanoflex ® Tex 2 and Nanoflex® zero NMR works effortlessly if you follow the 4 steps below:

Step 1 – Preparing the wood

The first step is to ensure that the wood to be impregnated is clean, dry and free from dust or any other soiling. In addition, it may be useful to lightly sand the surface to be treated beforehand to ensure better absorption of the impregnation / waterproofing / proofing into the fibers of the material.

Step 2 – Applying the impregnation / waterproofing / proofing

The second step is to apply the appropriate impregnation / waterproofing / proofing by brush or spray application. It is important that the entire surface is coated evenly and without gaps with the impregnation. Pay particular attention to the edges and corners of the wood.

Step 3 – Drying the wood

To achieve the best possible result, you should give the material sufficient time to dry in the third step. It is best to dry at room temperature with good ventilation to accelerate drying by removing vapors. Unless otherwise specified in the relevant product data sheet, allow at least 24 hours drying time.

Step 4 – Re-treatment or refresher

The last and fourth step is an optional process, depending on the result of the impregnation. As soon as you notice that the protective effect of the treated material is diminishing, for example it is becoming less water-repellent, it is advisable to repeat the impregnation process in the form of a refresher. You can also do this if you are not completely satisfied with the result of the first impregnation.

Additional valuable tips for treating wood:

Shaded work area: Work outdoors in the shade to avoid UV rays.
Ideal temperature: Work at temperatures between 5 and 25°C to achieve the best results.
Correct brush selection: Follow the manufacturer’s instructions for brush selection:
- Solvent-based glazes: Follow the manufacturer’s instructions,
- Water-based products: Use plastic bristle brushes,
- Natural bristle brush: for streak-free glazes,
- Ring brush: high paint absorption, ideal for windows,
- Flat brushes: for larger surfaces in various widths,
- Paint rollers: for very large areas.
Weather conditions: Work in dry, warm weather without direct sunlight.
Even application: Apply impregnation / waterproofing / proofing evenly and not too thickly.
Compatibility test: Test the impregnation / waterproofing / proofing on an inconspicuous area.

How long does the impregnation / waterproofing / proofing protect the wood?

The durability of wood impregnation is influenced by various factors. These include, among others:

Type of impregnation / waterproofing / proofing
Wood species
Stress on the wood
Weather conditions

With frequent use and heavy wear, the impregnation can lose its effectiveness more quickly. In addition, the longevity of the impregnation varies depending on the type of wood. Certain woods, such as teak, retain their protective properties longer than others. Proper care, which includes regularly refreshing the impregnation, can significantly extend the life of the wood preservative. Extreme weather conditions, sunlight and other environmental influences also contribute to faster degradation of the impregnation. As a general rule, Nano-Care® wood impregnations normally provide protection for 2 to 5 years. However, in the event of heavy use or extreme weather conditions, a new application may be necessary after just 1 to 2 years. As soon as the water repellency is no longer present, it is time for a new treatment. It is also important to maintain the wood regularly and check whether a new impregnation is necessary; we also have the right tips for this:

Regular cleaning: Clean the wood regularly to remove dirt, dust and algae and to protect the impregnation / waterproofing / proofing.
Special cleaners: Use a special wood cleaner that cleans the wood without damaging the impregnation.
Avoid aggressive cleaning agents: Avoid aggressive cleaning agents in order to maintain the integrity of the impregnation / waterproofing / proofing.
New impregnation layer: If necessary, apply a new impregnation layer to maintain the protection.

What are the consequences of an infestation with blue stain fungus?

An infestation with blue stain fungus has various consequences for the affected wood. The blue stain fungus leads to an unsightly blue-grey discoloration of the material, which is particularly undesirable for high-quality wood products.

The fungal infestation also changes the physical properties of the wood, impairing its strength and elasticity and making it more susceptible to further damage. As a result, the affected wood may no longer be suitable for its original use.

In addition, hygiene concerns may arise, especially if the wood is used in sensitive areas such as construction or furniture.

It is therefore important to protect wood from fungal infestation and to react quickly if an infection is suspected in order to prevent further damage.

We therefore recommend impregnating the material before using it for the first time to ensure continuous protection against fungal infestation.
