Why has my wood floor turned black?

Why is my wood floor dark?

Moisture, mold and ultraviolet rays from the sun are the main culprits in the darkening of wooden floors. Understand the reasons in detail below to help you find the most suitable solution.

What is Floor Restoration? The Ultimate Process Revealed

Wet bamboo flooring

When moisture comes into close contact with the surface of wood, the darkening of the wood from water is particularly noticeable in some types of wood. This is triggered by the interaction of minerals contained in the water with the tannins inherent in the wood itself. As a result, floors that were originally lighter in color may turn darker or even take on a black hue.

In addition, for those who keep pets at home, it is especially crucial to keep an eye on the condition of the wooden floor, as pet urine can have a similar negative effect.

Mold and Mildew

Mold can be one of the main culprits in the darkening of wooden floors. When wooden floors are wet, black mold can quickly spread across the surface. If the floor is not dried in a timely manner, the mold will grow as its numbers continue to grow. On light-colored bamboo flooring, these black spots will undoubtedly bring great visual discomfort. These black streaks will spread as the mold grows and you must take immediate action to stop them from developing.

Ultraviolet Rays

UV rays from the sun are seen as one of the potential contributors to the darkening of wooden floors. This is especially true for oak floors, which are highly susceptible to darkening if exposed to direct sunlight for a long period of time. When wooden furniture in your house is directly exposed to UV rays, you need to take precautions in advance.
