What is hard oil? Natural protection for wooden floors, furniture, and other wood surfaces.

Introduction

Wood is one of the most beautiful and durable natural materials, but it requires protection against moisture, wear, and dirt. One of the most effective ways to preserve the strength and appearance of wood is natural hard oil, which is often compared to hard wax oil (oil with hard wax).

In this article, we will explore what hard oil is, how it works, and how it differs from other wood protection methods.

What is hard oil, and how does it work?

Hard oil is based on a blend of vegetable oils and natural resins that harden through oxidation, creating a highly durable and wear-resistant protective layer within the wood fibers. Unlike hard wax oil, which often forms a thin surface layer, hard oil fully penetrates the wood, making it more resistant to mechanical stress and moisture.

Main properties of natural hard oil:

• Deeply penetrates wood pores and fibers.
• Protects against moisture and stains.
• Strengthens the wood structure, making it more durable.
• Does not alter the natural appearance of the wood but enhances its texture.
• A natural and eco-friendly solution without synthetic additives.

Why choose natural hard oil over varnishes or synthetic waxes?

Nowadays, many people opt for synthetic varnishes or waxes for wood protection, but natural hard oil offers significant advantages:

✅ Does not form a "film" on the wood surface – allows the wood to “breathe” and regulate moisture.

✅ No need for sanding when reapplying – maintenance is much easier.

✅ Deeply penetrates the wood pores and fibers, preventing cracks and deformation.

✅ Safe for children and food-contact surfaces – complies with DIN EN 71-3 standards.

❌ Varnish – often forms a hard "film" layer that can crack and peel over time.

❌ Synthetic wax – provides surface-level protection but is less resistant to mechanical wear.

Where is hard oil best used?

Hard oil is especially suitable for high-traffic surfaces that require durable and long-lasting protection:

• Wooden floors and parquet – provides protection against moisture and dirt as well as excellent resistance to mechanical stress.
• Worktops and tables – protects against household liquids and stains.
• Stairs – increases wear resistance.
• Furniture – preserves the natural look while making the wood more durable.
• Restoration of historic wooden floors – a natural and sustainable method.

 

How does hard oil differ from other similar oils?

There are various wood protection products on the market, such as hard wax oil, wax oil, and regular wood oil, but not all oils are the same in composition. Synthetically enhanced oils often contain polyurethane additives or solvents that can alter the natural properties of wood and form a hard "film".

Natural hard oil:

• Free of solvents and synthetic resins.
• Deeply penetrates the wood and does not form a "film".
• Eco-friendly and biodegradable product.

Synthetic oils:

• Often contain solvents that can release harmful emissions.
• Frequently form a "film" that can crack and peel.
• More difficult to restore – requires sanding to remove the previous coating.

Why choose natural hard oil?

If you are looking for long-lasting, natural, and durable wood protection, AURO hard oil is an excellent alternative to varnishes and synthetic waxes. It deeply penetrates the wood and protects the surface from wear, moisture, and dirt while preserving the natural properties of the wood and allowing it to "breathe".
