Terracotta.

Burnt reds, rose dust, and tiny flaws: proof that a surface can be imperfect and exacting at once.

Clay that remembers the kiln.

Terracotta means “baked earth”: natural clay shaped into tiles and fired at relatively low temperatures. The colour comes from the minerals in the clay — iron gives the familiar reds — and from where each tile sat in the kiln. No two are quite alike, which is why a terracotta floor reads as warm even though it is cool to the touch.

Low firing also makes it porous and softer than porcelain. That is its charm and its responsibility.

“The most practical room can still have a horizon.”

Handmade or machine-made?

  • Handmade tiles are pressed or moulded by hand and dried in the open. They vary in size, thickness and colour, and carry marks of their making. Laying them takes skill and wider grout joints.
  • Machine-made (extruded) tiles are denser, more regular and easier to lay, with a calmer, more even look.
  • Reclaimed tiles come with decades of patina already built in — and the variability of their past lives.

Sealing is not optional

Unsealed terracotta absorbs water, oil and dirt readily. Tiles are usually sealed after laying (and often before grouting, to stop grout haze staining the surface). Traditional finishes use linseed oil and wax; modern penetrating sealers give good protection with less upkeep. Either way, expect to refresh the finish in busy areas as it wears.

Everyday care

  • Sweep regularly and damp-mop with a pH-neutral cleaner.
  • Avoid acidic and harsh alkaline cleaners, which strip sealers and wax.
  • Wipe up oil and wine promptly, especially in kitchens.
  • Waxed floors can be buffed back to a soft sheen and re-waxed where worn.

How it ages

Terracotta deepens and softens with years of use, gathering a patina that many people prize. Chips at edges tend to blend in rather than stand out. If you want a crisp, uniform floor forever, porcelain made to look like terracotta is the more predictable choice — but it will not age the same way.

Indoors and out

Most terracotta is intended for interiors. In climates with freezing winters, only use tiles specifically rated as frost-resistant outdoors, since absorbed water can crack them when it freezes. Terracotta also works well with underfloor heating.

Questions

Terracotta, answered.

Do terracotta floor tiles need to be sealed?

Yes. Terracotta is porous, and without a sealer or oil-and-wax finish it stains easily. Sealing is usually done after laying and before or during grouting.

Is terracotta good for kitchens?

It is a classic kitchen floor: warm-looking, hard-wearing when sealed, and forgiving of wear. Keep the finish maintained and wipe oily spills promptly.

What is the difference between terracotta and Saltillo tile?

Saltillo is a type of handmade terracotta from the Saltillo region of Mexico. It is typically fired at lower temperatures, making it softer and more porous, with strong variation in colour.

Can terracotta be used outdoors?

Only if the tile is rated frost-resistant for your climate. Standard interior terracotta can crack when absorbed water freezes.
