Earthen and terracotta floors

History, traditional maintenance and how to protect them today

Clay floors, also known as terracotta floors, are one of the most appreciated options in traditional homes, country houses and renovation projects.

Their warm aesthetic, natural origin and great durability make them a timeless flooring that, well cared for, can last for generations. In this article we explain what terracotta floors are, how they were maintained in the past, what problems appear if they are not protected correctly and what is the best way to treat them today in a natural manner.

1. What are clay or terracotta floors?

Fired-clay floors or terracotta tiles are made from natural clays fired at low temperature. This gives them a porous texture and a unique finish, with colour variations ranging from red to ochre.

They are very common in:

  • Old houses and rural dwellings
  • Courtyards and outdoor porches
  • Kitchens and communal areas
  • Renovation of historic buildings

2. History of terracotta floors

The use of clay as flooring dates back thousands of years. Civilizations such as the Roman Empire already used ceramic floors in villas, baths and public buildings for their resistance and ease of maintenance.

For centuries, terracotta floors were the most common material in Mediterranean homes, wineries and agricultural buildings, reaching our days as a symbol of traditional and sustainable architecture.

3. Traditional maintenance of clay floors

Before modern varnishes, the treatment of clay floors was carried out with natural products. Among the most used were:

  • Natural vegetable oils
  • Linseed oil
  • Grape-seed oil (very common in wine-growing areas)
  • Natural waxes

These methods served to:

  • Protect the clay without sealing it
  • Reduce the absorption of stains
  • Enhance the natural colour of the terracotta
  • Make daily cleaning easier

This type of oil for clay floors allowed the material to keep breathing.

4. Advantages of terracotta floors in today’s homes

Today, more and more people are looking for natural and sustainable floors. Terracotta stands out for:

  • Its durability
  • Its easy restoration
  • Its warm and natural aesthetic
  • Its compatibility with ecological treatments

A well-maintained clay floor does not deteriorate over time, it improves.

5. Common problems in clay floors

When the right products are not used, it is common to find:

  • Grease stains that are hard to remove
  • Uneven darkening
  • Loss of colour
  • Fragile or dusty surfaces

In most cases, these problems arise from using synthetic sealers or overly aggressive products that close the pores of the clay.

6. How to clean and maintain a terracotta floor correctly

For proper cleaning of clay floors it is recommended to:

  • Use neutral soaps
  • Avoid acidic or abrasive products
  • Not flood the floor with water
  • Apply periodic protective treatments

The aim is to protect without plasticizing.

7. Natural protection with oil for clay and terracotta floors

Following tradition, but adapting it to today’s needs, there are specific solutions such as Stone and Terracotta Oil, formulated to protect porous materials without altering their nature.

This type of protective oil for terracotta:

  • Nourishes the clay deeply
  • Reduces the absorption of water and stains
  • Enhances the original colour
  • Maintains the breathability of the material

It is a solution particularly suited to those looking for how to protect a clay floor naturally.

8. Final tips for preserving clay floors

  • Always apply the treatment on a clean, dry floor
  • Repeat the protection according to use and foot traffic
  • Avoid aggressive chemical products
  • Use rugs in areas of greater wear

A good treatment extends the life of the floor and keeps its beauty for decades. At RedVerde we believe that clay and terracotta floors should be cared for as they always have been: with products that respect their origin and their function. Choosing natural solutions is the best way to preserve them today and in the future.
