Why do people question the point of varnish?
The subject of floor varnishing keeps coming back, because it has sparked many conflicting opinions. Some are convinced it’s essential—“otherwise the floor will wear out quickly.” Others argue it’s a needless cost and that the whole “varnish duty” is just a marketing ploy from flooring product manufacturers.
Popular opinions and myths
The most common claims include:
-
“The varnish will wear off after just a few months”
-
“It’s only a shiny layer, it offers no real protection”
-
“It’s better to wipe it with oil now and then, since varnish doesn’t do anything”
-
“Floors weren’t varnished in the past and they were fine”
Such statements may sound convincing—especially when repeated by friends or someone online who shares a “personal story.” The problem is, they often lack context: the type of flooring, how it’s used, or even the quality of the varnish itself.
Where do these beliefs come from?
There are usually two main sources of misinformation:
-
The Internet – forums and discussion groups are full of advice taken out of context and stories from years ago, when completely different products were in use.
-
Conversations with friends – often based on isolated cases that don’t necessarily reflect today’s technology and standards.
On top of that, there’s a natural desire to save time and money, making it easy to accept the version that justifies skipping varnishing altogether.
Why is it worth verifying these claims?
Because varnish, contrary to popular belief, is not just decoration. It’s a protective layer that can extend the life of your floor by many years. That’s why it’s worth basing your decision on reliable information rather than myths—especially if you want the results of your renovation to last and look good for a long time.
What does varnish really do?
Floor varnish is not just a “shiny coat.” It’s a protective layer with very specific roles—both practical and aesthetic.
How it works – creating a protective layer
Once applied and dried, varnish forms a thin but durable coating on the floor’s surface. This layer acts as a barrier between the floor and everyday threats: dirt, moisture, high heels, or chair wheels. As a result, the floor itself wears out more slowly, since the varnish takes the “first hit” in the form of minor damage.
Protection against wear, scratches, and moisture
Varnish limits the penetration of moisture into the material, protecting it from swelling, warping, or discoloration. A high-quality finish also makes scratches less likely to form—while it won’t prevent them completely, they will be shallower and less noticeable. In high-traffic areas such as hallways and living rooms, this is a major advantage.
Impact on aesthetics
Varnish enhances the natural color of the material and gives it the desired finish—from high gloss to satin or even complete matte. This makes it possible to highlight the character of the interior and match the floor’s appearance to the room’s style.
When is varnish especially necessary?
Although in theory varnish can be applied to any wooden or natural cork floor, in practice there are situations where its use makes a real difference.
Floors with heavy foot traffic
If several people walk on it daily, chairs are frequently moved around, or pets run across it—varnish becomes the first line of defense. In living rooms, hallways, offices, or commercial spaces, without a good protective layer the floor will quickly lose its fresh look and show “history” in the form of scratches and wear marks.
Areas exposed to moisture and dirt
Entryways, kitchens, or spaces near patio doors are places where water, mud, or sand are part of daily life. Varnish reduces water absorption and prevents dirt from penetrating the structure of the material, making cleaning easier and protecting against permanent stains.
Floors made of natural cork
Natural cork is warm, resilient, and pleasant to the touch, but varnish adds an extra protective coating that helps the material maintain both its properties and appearance for longer.
Softwood vs. hardwood
Pine or spruce are softwoods and scratch easily—here varnish is highly recommended. For hardwoods like oak or ash, protection is also useful, though more for moisture resistance and enhancing aesthetics than for mechanical reinforcement.
Summary
Varnishing a floor is not just about aesthetics—it is above all an effective way to protect the material from wear. By creating a layer resistant to moisture and dirt, varnish extends the life of the floor and allows you to enjoy its appearance for longer without costly renovations.
While you may find opinions online that it’s an unnecessary step, in practice, in high-traffic areas, spaces exposed to moisture, or with softwood or cork flooring, varnish proves highly effective. Moreover, choosing the right finish—matte, semi-matte, or glossy—can give the interior the desired look.
Therefore, the decision to varnish should be based not on myths but on reliable information and actual needs. This way, you’ll avoid disappointment and give your floor the protection it truly requires.
FAQ
1. Does every floor need to be varnished?
No. If the floor is factory-finished or protected by another method (e.g., oiling), varnishing may be unnecessary. However, it’s worth considering for raw wood, cork, and floors requiring additional protection.
2. How long does a layer of varnish last?
On average 5–10 years, depending on the product quality, level of use, and maintenance. In less frequently used areas, it can last even longer.
3. Can you varnish a floor yourself?
Yes, but it requires proper surface preparation, even application, and knowledge of drying times for each layer.
