Impregnation is an indispensable part of the care and maintenance of a wide variety of materials. They give textiles, leather, wood, concrete and stone an additional protective layer that makes them water and dirt repellent. In this article, we take a detailed look at what exactly impregnation is, which materials are suitable for it and how you can impregnate effectively using modern, environmentally friendly products.

What is impregnation and why is it important?

Basics of impregnation

Impregnation refers to the process of applying a substance, e.g. impregnation sprays, to make materials such as textiles, leather or stone water and dirt repellent and to maintain breathability. This is done by filling the pores of the material surface with a water- and dirt-repellent chemical. The impregnating agents used can vary depending on the area of application and range from silicones and waxes to modern fluorocarbons and nano-impregnations. Proper impregnation can significantly extend the service life of products and improve their usability under adverse weather conditions.

The aim of the impregnation process is to form an invisible, protective layer that repels moisture, wetness and dirt. The original breathability of the material is retained, which is particularly advantageous for clothing. Successfully impregnated materials not only resist moisture better, but are also easier to clean as dirt adheres less. These properties make impregnation an essential step in the care of many products.

The importance of water and dirt-repellent surfaces – the lotus effect

Dirt and water-repellent surfaces, often inspired by the natural lotus effect, play an important role in protecting materials. Protection against moisture and dirt is essential, especially for outdoor and work clothing and footwear, to ensure their functionality and comfort under extreme conditions.

The lotus effect, named after the lotus flower, whose leaves are effectively water-repellent due to their microscopically structured surface, serves as a model for many impregnated surfaces. This technology is not only used in the textile industry, but also in the impregnation of wood, stone and concrete.

The different types of impregnating agents and their application

Impregnating agents come in a variety of formulations, including impregnating sprays, pump sprays, brush-on solutions and immersion solutions. These products can be based on silicone, wax, fluorocarbon-containing substances, solvents or water. Each of these chemicals offers different advantages. Fluorocarbons, for example, offer a very high level of protection against water and oil, but are controversial due to their environmental impact. Silicone-based impregnating agents are often the choice for leather and offer good protection while maintaining the flexibility of the material. Our nano sealants are also ideal as impregnating agents and can be used as an impregnating spray with a spray head.

When selecting an impregnating agent, attention should be paid to the specific requirements of the material to be treated and the desired effect. The correct use of impregnating agents can significantly improve the function and service life of textiles and other materials by protecting them from water, dirt and other contaminants.

Which materials can be impregnated?

Impregnation of leather and textiles

Leather and textiles, especially for outdoor use, benefit greatly from impregnation. This treatment makes leather or suede water and dirt repellent, makes it easier to care for and extends its lifespan. Impregnation makes textiles waterproof without impairing breathability, which is particularly important for sports and outdoor clothing. This guarantees comfort in different weather conditions. Impregnated shoes also stay clean and dry for longer.

Impregnation of concrete & stone

Impregnation effectively protects concrete and stone by sealing these materials against water, dirt and pollutants. This prevents mold growth and decomposition, which is particularly important for buildings to ensure durability and resistance. Impregnation also makes stone surfaces more resistant to weathering and stains. The treatment also makes these surfaces easier to maintain, as they repel water and dirt. Special impregnation products provide deep protection and are ideal for outdoor areas such as monuments and terraces to preserve their appearance and function.

Impregnation of wood

The purpose of impregnating wood is to protect this natural material against moisture, pests and decay. Especially for outdoor applications, such as garden furniture, decking or wooden facades, this type of protection is essential to make the wood weatherproof and resistant to environmental influences. The impregnation not only improves durability, but also makes the wood easier to maintain and clean by creating a surface that is less susceptible to dirt and stains. Specialized impregnating agents can also preserve or enhance the natural appearance of the wood.

How do you impregnate correctly?

Instructions: Step-by-step guide to proper impregnation

To impregnate materials correctly, you should follow these steps:

Preparation: Clean the surfaces thoroughly and allow them to dry completely. This ensures the best adhesion of the impregnating agent.
Product selection: Choose a product that is specifically suitable for the materials to be treated. Whether spraying or painting, always follow the manufacturer’s instructions for the respective product.
Application site: Apply the product in a well-ventilated area or outdoors to avoid vapors.
Application: Spread evenly and in sufficient quantity, but avoid oversaturation of the materials.
Drying: Give the materials enough time to dry so that the protective layer can bond firmly.
Second coat: If necessary, apply a second coat after the first is completely dry to ensure full coverage.

This careful procedure ensures an effective and long-lasting impregnation that protects the material from water, dirt and wear.

Environmentally friendly impregnating agents: do they exist?

Note: Our impregnations and sealants do not contain any PFC substances and are food-safe.

Nano sealants as the means of choice

We refer to our breathable impregnations as sealants, but strictly speaking they are impregnations. Most of our products are food-safe so that they can be used without hesitation.

The issue of PFCs and alternatives

The use of PFCs (perfluorocarbons) in impregnating agents has been controversial for years due to their harmful effects on the environment and health. PFCs are chemicals that are hardly degradable in nature and accumulate in the environment. These include PFOS (perfluorooctane sulfonic acid) and PFOA (perfluorooctanoic acid), which are used in textiles for their water and dirt-repellent properties.

Biodegradable and PFC-free impregnation options

Biodegradable and PFC-free impregnation options are a promising alternative to traditional impregnation agents. These products completely dispense with fluorocarbons and other harmful chemicals and instead rely on natural or synthetic substances that are environmentally friendly and harmless to humans. The development of such impregnating agents is progressing rapidly with the aim of providing a solution that is both effective and environmentally friendly. These impregnations are particularly suitable for textiles, leather and other materials that are regularly exposed to the weather and offer long-lasting protection against moisture and dirt.

Impregnation and health: what needs to be considered?

Health and environmental protection are important when using impregnating agents. Many products contain chemicals such as PFCs, which are persistent and difficult to break down. These can accumulate in the environment and have harmful effects on humans and animals. It is therefore important to choose products that are environmentally friendly and harmless to health.

Protective measures:

Wear protective gloves: Avoid direct skin contact with the impregnating agent.
Ensure good ventilation: Work in well-ventilated areas or outdoors to prevent inhalation of harmful vapors.
Allow to dry sufficiently: Allow treated objects to dry thoroughly before using them again.

It is also important:

Read the instructions: Inform yourself about the application and possible risks by reading the instructions for the impregnating agent.
Observe safety information: Follow the safety instructions, especially for environmentally friendly and PFC-free products.

By selecting safe products and observing protective measures, health risks can be minimized and environmental protection promoted at the same time.

Avoid common mistakes and problems when impregnating

Why impregnation sometimes doesn’t work

Sometimes impregnation does not work as expected, which can have various reasons:

Incorrect application: Incorrect application may impair effectiveness.
Unsuitable product: The choice of impregnating agent must be tailored to the specific material.
Inadequate preparation: Thorough cleaning and drying of the material is essential for effective impregnation.
Lack of renewal: The impregnation must be renewed regularly as its effect diminishes over time.
Not following the instructions: Too little or too much of the product can lead to poor results.

To avoid these problems, it is important to choose the right product carefully, prepare the surface correctly and apply the impregnation according to the manufacturer’s instructions and renew it regularly.

The right choice of impregnating agent for different materials

The right choice of impregnating agent is crucial to provide effective protection for different materials. Here are some points to bear in mind:

Textiles: Textiles, especially those that are subject to heavy wear and tear (such as ski clothing), require waterproofing that provides waterproofing without impairing breathability.
Leather: Leather, especially sensitive types such as suede, requires specific impregnating agents that protect the material without changing its texture.
Outdoor clothing with membranes: For clothing with waterproof membranes, e.g. GORE-TEX, waterproofing agents are required to maintain and reinforce the functionality of the membrane.

Unsuitable impregnation can reduce the effectiveness or damage the material. Therefore, inform yourself well about the ingredients and, if necessary, consult specialists to find the optimum product for your specific material.

Tips for regular care and maintenance of the impregnation

Careful and regular maintenance is essential to maintain the effectiveness of the impregnation. This care covers several aspects, from correct cleaning to proper storage of the treated materials. It is important to always follow the manufacturer’s care instructions, as these are specifically tailored to the material and the type of impregnation.

For textiles, this generally means using mild detergents that have been specially developed not to attack the impregnation and therefore not to impair the protective function. For leather products, however, the use of special leather cleaners is recommended, which not only clean the material but also nourish it without damaging the waterproofing layer.

After each cleaning and especially before long-term storage, it should be considered whether re-impregnation is necessary to renew the protection against moisture and dirt. The way in which impregnated materials are stored should also not be underestimated. They should always be stored in a dry and well-ventilated place to prevent the formation of moisture and mold.

Observing these care tips makes a significant contribution to maintaining the function and appearance of impregnated materials and significantly extends their service life. Regular use of these tips will maximize the effectiveness of the waterproofing and ensure protection from the elements.
