The importance of caring for our environment cannot be overstated, and one of the ways we can contribute is by making informed decisions about the products we use. This includes the wood treatments we apply in our homes and on our furniture. Our objective in this guide is to familiarise you with sustainable and environmentally friendly wood treatment options that are not just good for the planet but for your health as well.

Understanding Wood Treatment

What is Wood Treatment?

Wood treatment refers to the process of applying substances to wood to enhance its durability, improve its appearance, and protect it from factors such as insects, fungi, and weather conditions. Traditional methods of wood treatment often involve the use of chemical preservatives, varnishes, and paints, many of which can have detrimental effects on the environment due to their toxic constituents and the processes used to manufacture them.

The Need for Eco-Friendly Options

The conventional methods of wood treatment, while effective, often come with environmental and health concerns. Many treatments contain volatile organic compounds (VOCs) and other chemicals that can be harmful to the environment and humans. As such, there is an increasing need for eco-friendly alternatives that are both effective and safe. Eco-friendly wood treatments, such as natural wood stain, are those that are designed to have as little impact on the environment as possible, from the sourcing of the ingredients to the manufacturing process and, finally, to their application and disposal.

Principles of Eco-Friendly Wood Treatment


In the context of wood treatments, sustainability refers to using products that are derived from resources that are managed in a way that prevents their depletion. This means sourcing treatments made from renewable resources and ensuring that the entire lifecycle of the product is eco-friendly, from manufacture to disposal. Using sustainably sourced materials is a crucial part of preserving our environment and combating climate change.

Low Toxicity

Traditional wood treatments often contain high levels of toxic materials. These toxins can be harmful to humans, animals, and the wider environment. Eco-friendly treatments, on the other hand, have significantly lower toxicity levels. These products are formulated to reduce, and in some cases eliminate, the presence of harmful substances, providing a safer option for the user and the environment.


An essential aspect of eco-friendliness is effectiveness. It’s not just about creating a product that’s safe for the environment; it also has to serve its purpose efficiently. A balance must be struck between creating a product that’s environmentally friendly and one that’s durable and long-lasting. The longer a treatment lasts, the less frequently it needs to be reapplied, resulting in a reduced environmental impact. Thankfully, many eco-friendly wood treatments offer high durability without compromising on their green credentials.

Eco-Friendly Wood Treatment Options

Natural Oils

Natural oils, such as linseed, tung, and hemp oil, are excellent eco-friendly options for wood treatment. These oils penetrate deep into the wood, providing robust protection against moisture, while enhancing the grain and natural beauty of the timber. Compared to traditional oil-based treatments, these natural wood oils don’t contain harmful volatile organic compounds (VOCs), making them safer for you and the environment.

Plant-Based Stains and Finishes

Plant-based stains and finishes use extracts from plants, seeds, and nuts to give a rich, long-lasting colour to wood. They are non-toxic, biodegradable, and safe to use on all types of wood. They can be used for a variety of applications, from furniture to decking, and they provide a great alternative to synthetic, chemical-laden stains.

Low or No-VOC Paints

Volatile organic compounds (VOCs) are a group of carbon-based chemicals that easily evaporate at room temperature. High VOC levels are harmful to human health and the environment. In recent years, the development of low or no-VOC paints has been a significant step towards eco-friendly wood treatment. These paints maintain the performance of traditional paint, providing excellent coverage and durability while significantly reducing the environmental footprint.

Applying Eco-Friendly Wood Treatments

Preparation of Wood Surfaces

Before applying any treatment, it’s crucial to prepare your wood surfaces adequately. Start by cleaning the surface of any dust or dirt using an eco-friendly cleaner. For older wood, you might need to sand it lightly to remove any old treatment or rough patches. This will ensure the treatment adheres well and provides maximum protection.

Application Techniques

Eco-friendly wood treatments can be applied using a brush, roller, or spray system, depending on the product and the surface area. It’s crucial to apply a thin, even coat and allow it to dry thoroughly before adding any additional coats. Remember to follow the manufacturer’s instructions for the best results.


In conclusion, there are numerous eco-friendly wood treatment options available that are not only kind to the environment but also provide excellent protection and enhancement to your wood surfaces. Whether you choose natural oils, plant-based stains, or low VOC paints, you’re making a positive choice for the health of your home and the environment. We encourage you to explore these options for your next project and make a contribution to a more sustainable and healthier world.
