How often you should oil your wood flooring? A Detailed Guide for Maintaining Solid and Engineered Floors

Wood flooring, with its rich textures and enduring elegance, can enhance the beauty of any space. To keep it looking its best, however, regular maintenance—particularly oiling—is key. Oiling not only protects the wood but also nourishes it, highlighting the natural grain and deepening the colour. But how often should you oil your wood flooring? The answer depends on several factors, such as the type of wood, the level of foot traffic, and the environment it’s in.

In this comprehensive guide, we’ll explore the ideal oiling frequency for both solid wood floors and engineered wood floors, including details specific to parquet patterns such as chevron parquet and herringbone parquet. You’ll also find expert tips on sanding and re-oiling, a look at eco-friendly oiling options, and an investigation into some of the most popular oil brands on the market, such as Osmo, Saicos, Ciranova, and Rubio Monocoat.

1. Understanding the Importance of Oiling Wood Floors

​Oiling wood floors is essential for a variety of reasons. It penetrates the wood, protecting it from within while enhancing its natural beauty. Unlike surface finishes like varnish or lacquer, oils permeate the wood, offering a long-lasting layer of protection that’s breathable and resistant to daily wear and tear.

• Nourishment: Wood can dry out over time, especially if it's exposed to dry climates or underfloor heating. Regular oiling replenishes the wood’s natural oils, preventing cracks and warping.

• Protection: An oiled finish creates a barrier against dirt, moisture, and stains, prolonging the floor’s life.

• Aesthetic enhancement: Oiling intensifies the wood’s natural grain, giving it a richer, more luxurious appearance.

​2. Solid vs. Engineered Wood Flooring: Oiling and Refinishing

When considering oiling frequency and maintenance, it’s crucial to differentiate between solid wood and engineered wood flooring.

2.1. Solid Wood Flooring

Solid wood floors consist of a single piece of timber, which means they can be sanded and refinished multiple times over their lifetime. They tend to require oiling every 1-2 years depending on usage. However, in high-traffic areas, oiling may be required annually to maintain the wood’s appearance and durability.

Solid wood flooring is ideal for long-term wear and can be sanded deeply to remove scratches, dents, or worn finishes before reapplying oil. Careful attention should be paid to the grain direction when sanding, especially in design patterns like chevron or herringbone.

2.2. Engineered Wood Flooring

Engineered wood flooring is constructed with a thin layer of real wood on top of a plywood base. The thickness of the top layer (also called the "wear layer") determines how many times it can be sanded and refinished. This wear layer typically ranges from 2mm to 6mm in thickness. If your engineered flooring has a thinner top layer (around 2mm), you may only be able to sand and refinish it once or twice before it wears through to the plywood base.

Before sanding engineered wood flooring, especially parquet patterns like herringbone, it’s essential to know the thickness of the top layer to avoid damaging the floor. Once you’ve sanded down to bare wood, you can reapply an oil or hard-wax oil finish.

3. Chevron, Herringbone, and Design Parquet: Sanding and Re-Oiling

Chevron, herringbone, and other design parquet flooring can be more delicate to sand due to the intricate patterns. Care must be taken not to over-sand, as uneven pressure can damage the parquet’s sharp edges or alter its design.

Sanding Process for Design Parquet:

• Step 1: Prepare the floor: Clean the floor thoroughly to remove dust, dirt, and debris. Use a light abrasive if necessary.

• Step 2: Sand gently: Use a fine grit sandpaper (around 180-240 grit) to lightly sand the surface. Be careful to sand with the grain as much as possible, even with intricate patterns.

• Step 3: Re-oil: After sanding, clean the floor again and let it dry before applying the oil. Follow the grain and the flow of the pattern to avoid an uneven finish. Work in sections to ensure even oil absorption.

4. Factors Affecting Oiling Frequency​

4.1. Wood Species

Different wood species vary in their natural oil content and density, which impacts how often they need re-oiling:

• Oak: A popular choice for European oak herringbone parquet, oak is moderately dense and requires oiling every 1-2 years.

• Ash: A light, durable wood with an open grain, ash requires re-oiling every 1-2 years, though in high-traffic areas it may need more frequent oiling.

• Walnut: A softer wood, walnut should be oiled more often, particularly in high-use areas, around once a year.

• Douglas Fir: Known for its softness, this species may need more frequent oiling, especially in busy areas.

• Exotic woods: Woods like teak or thermally modified wood (thermowood) often have a higher natural oil content and may not need oiling as frequently, though they still require attention.

​4.2. Environmental Conditions

• Dry climates or underfloor heating: Floors can dry out faster in these environments, requiring more frequent oiling.

• Sunlight exposure: Wood exposed to direct sunlight may dry out and fade over time. Regular oiling can help prevent this.

• Foot traffic: High-traffic areas will wear out an oil finish quicker. Entryways, kitchens, and hallways may need touch-ups between full oiling treatments.

5. Types of Eco-Friendly Oils for Wood Flooring

There’s growing demand for eco-friendly, sustainable products, and wood oils are no exception. Many homeowners are opting for oils made from natural ingredients with low volatile organic compounds (VOCs). Here’s an overview of some eco-friendly oils on the market:

5.1. Natural Oils:

• Linseed Oil: A traditional oil derived from flax seeds, linseed oil penetrates deeply but can yellow over time, especially on lighter woods like ash or oak.

• Tung Oil: Harvested from the seeds of the tung tree, this oil offers superior water resistance and is ideal for areas prone to spills.

5.2. Hard-Wax Oils:

Hard-wax oils combine the benefits of both oils and waxes, offering deep penetration with a durable, breathable surface finish. They are popular for their eco-friendliness and low-VOC formulas, making them a preferred choice for environmentally conscious homeowners.

Popular hard-wax oil brands include:

• Osmo: Known for its natural, eco-friendly formulas, Osmo is a market leader. Their oils are micro-porous, allowing the wood to breathe while protecting it from moisture and stains.

• Saicos: Another eco-friendly brand, Saicos offers hard-wax oils that provide excellent durability and water resistance.

• Ciranova: This Belgian brand offers a range of natural wood oils, including hard-wax oils, known for their ease of application and eco-friendly credentials.

• Rubio Monocoat: Famous for its "one-coat" system, Rubio Monocoat uses natural ingredients to deliver highly durable, low-VOC finishes. The oil bonds at a molecular level, making it ideal for areas with heavy traffic.

6. The Oiling Process: How to Oil Your Floor

Whether you have a solid wood floor or engineered flooring, the oiling process follows a few basic steps. The difference lies in how you prepare the surface and whether sanding is necessary, especially for design parquet like chevron and herringbone.

Step 1: Prepare the floor

Clean the floor thoroughly using a vacuum or a dry mop to remove dust and debris. If sanding is needed, use fine-grit sandpaper to smooth out any scratches or uneven areas, taking extra care with parquet designs.

Step 2: Apply the oil

Choose the right oil for your floor (such as hard-wax oil or natural oil). Apply the oil with a roller, brush, or lint-free cloth, working with the grain of the wood. In intricate patterns, work carefully to avoid uneven application.

Step 3: Wipe away excess oil

Let the oil soak into the wood for 10-30 minutes before wiping away any excess with a clean cloth. Leaving too much oil on the surface can lead to a sticky finish.

Step 4: Buff the floor

For a professional finish, buff the floor with a soft cloth or a buffing machine to enhance the sheen and ensure even oil distribution.

Step 5: Allow time to cure

Most oils will dry within 8-24 hours, but full curing can take up to a week. During this time, avoid heavy traffic and be careful when moving furniture back onto the floor.

7. Common Mistakes to Avoid

• Over-oiling: Applying too much oil can leave a sticky residue that doesn’t dry properly. Always apply sparingly and wipe off the excess.

• Using the wrong product: Not all oils are suitable for wood flooring. Ensure you use a product that’s formulated specifically for wood floors, such as hard-wax oil from brands like Osmo or Rubio Monocoat.

• Neglecting regular cleaning: Regularly clean your floor with a damp mop (not wet) to prevent dirt from becoming embedded in the finish, which can degrade the oil.
