Using Terracotta Flooring

 Choosing flooring materials involves research into performance, air quality, costs, and aesthetic fit. Terracotta tiles offer a durable, functional, and rustic option for many British homes.

What Is Terracotta Flooring?

Terracotta is a type of ceramic tile made from baked clay. The name is Italian for "baked earth." It is fired at a much lower temperature than other ceramic tiles and is known for its characteristic reddish-brown colour, which results from high iron content in the clay.

Historically, terracotta has been used for over 20,000 years for everything from roofing and flower pots to drainage pipes. It remains popular today due to its affordability, availability, and versatility across various architectural designs.

The Appearance of Terracotta

While reddish-brown is standard, colours can range from yellowish cream to deep browns depending on where the clay was sourced. The tiles can be shaped into various designs, providing many styling options. The overall vibe is often described as "bucolic," evoking the feeling of a Mediterranean villa or a traditional farmhouse.

Where Is It Traditionally Used?

• Mediterranean Region: A long-standing traditional choice in Italy, Spain, and Greece.

• Mexico: Often seen in haciendas.

• Southwest United States: Popular in states like New Mexico and Arizona.

Types of Terracotta Floor Tiles

• Density: High-density tiles are treated to be more durable and are a better choice for heavy-use areas like hallways or kitchens. Low-density tiles are cheaper but less suitable for main flooring.

• Porosity: Terracotta is naturally porous. "Natural" tiles are untreated and highly susceptible to stains and water retention.

• Finish: Tiles can be "burnished" (smoothed with abrasives) or glazed. Unglazed tiles are prone to mould and can crack in cold climates if absorbed water freezes—a significant consideration for unheated conservatories or outdoor patios in the UK. Glazed tiles offer significantly more protection.

Advantages and Disadvantages

Pros:

• Temperature Control: Naturally absorbs heat. While it helps keep rooms cool in summer, it is also an excellent partner for underfloor heating, as it retains and slowly releases heat.

• Eco-Friendly: A 100% natural product that is entirely recyclable.

• Durable: Impact-resistant, fire-resistant, and unaffected by wood-boring insects.

• Acoustics: Effective at absorbing sound and reducing echoes in large rooms.

Cons:

• Aesthetics: The rustic look and inconsistent colouring/shaping (often called "character") are not for everyone.

• Maintenance: Unsealed tiles absorb water, which can lead to mould or cracking.

• Climate Sensitivity: In the UK, outdoor applications require specific "frost-proof" terracotta to prevent the tiles from shattering during winter freezes.

Best Uses in the Home

• Kitchens: It pairs well with various unit styles, from Shaker-style cabinets to natural oak or modern slate finishes.

• Bathrooms: While beautiful, it requires annual seal checks to prevent moisture issues, especially near baths and showers.

Maintenance and Care

Daily cleaning requires only sweeping, dry mopping, or vacuuming. Spills should be blotted immediately to avoid permanent staining.

The Seal Test: To check if your floor needs resealing (typically every three years), pour a small amount of water on a tile. If it beads on the surface, the seal is intact. If it absorbs into the clay, it is time to reseal.

Steps to Reseal:

1. Clean: Sweep or vacuum thoroughly to remove grit.

2. Repair Scratches: Use fine-grit (1000-grit) sandpaper to gently smooth out surface scratches.

3. Mop: Clean with warm water and a little washing-up liquid; allow the floor to dry completely (this may take longer in the UK's humid climate).

4. Protect: Use masking tape to protect skirting boards and other surfaces.

5. Apply Sealant: Use a roller or brush to apply a tile sealer specifically designed for terracotta, available at most DIY stores or builders' merchants.

Renovating Dirty Terracotta Tile and Grout in East Cheshire

We were asked if we could restore the appearance of a large Terracotta tiled floor in a kitchen/dinner that had not been cleaned for many years. The sealer had mostly worn off in the high traffic areas but was still fairly thick under the table. Terracotta tiles are made from soft clay making it very porous and likely to absorb anything that lands on it; as a result, it’s important to maintain the sealer to stop this happening. Now with the sealer worn off completely in the busy parts of the floor anything that landed on the floor was very quickly absorbed into it.


The house was in Knutsford on the East side of Cheshire which was named as Best Place to Live in the North West” by the Sunday Times in 2017; being close to the Peak District and within easy reach of Liverpool and Manchester its easy to see why.

Deep Cleaning a Spanish Terracotta Tiled Kitchen Floor

My first task would be to completely remove the old sealer so the whole floor could be given a deep clean before resealing. It’s not a good idea to add a new sealer on top of another especially if you don’t know what was used before, it can also lead to a build of sealers on the tile which will darken their appearance. To do this I soaked the tiles in a strong dilution of Tile Doctor Remove and Go which is a powerful stripping and cleaning solution that’s designed to removes old coatings on tiles and draw out ingrained staining. After twenty to thirty minutes the solution was worked into the tiles using a black buffing pad fitted to a rotary buffer machine. I also used a wire hand brush along the grout lines to make sure they were cleaned as the scrubbing pad can fail to reach into the recess. It wasn’t long before the old sealer and dirt was released from the Terracotta which was then washed off the floor using water and a wet vacuum.


I inspected the floor at this stage and retreated any stubborn areas using the same process. I did have a few problems removing some greasy marks however I managed to get rid of these by applying Tile Doctor Wax Away worked in by hand with a scrubbing brush. Once I was happy that the floor was clean and free of old sealers it was given a final rinse to remove any trace of cleaning product, dried with the wet vacuum and left to dry out fully overnight.

Sealing a Terracotta Tiled Kitchen Floor

On my return the next morning I took a few damp readings to check the floor was dry before starting with the next step of sealing the tiles. All was well so began to add the first of multiple coats of Tile Doctor Seal and Go which is a water-based sealer that works really well on Terracotta and leaves a nice subtle sheen to the tile. Being was based it has the added advantage of not leaving a solvent smell as it dries.


The Terracotta took some time to seal completely, in fact ten coats of sealer were required to fully seal the tile. You can always tell when a tile is sealed by adding a small drop of water to the surface, if it forms into a bubble then its’ fully sealed.


I’m not sure you can appreciate the difference from my photographs but hopefully you can see that Terracotta tiles now look much fresher and the grout cleaner and lighter in colour.

Stripping and Resealing a Terracotta Tiled Kitchen Floor in Bristol

Terracotta tiles are always a popular choice for Kitchens but being made from clay they are porous and need to be sealed to prevent dirt from becoming ingrained in the tile. Once sealed though you need to remember Kitchens are high traffic areas, so you can expect the sealer to wear off quicker than it would elsewhere.

I mention this as a customer from Bristol asked me to do a survey on her Varnish Sealed Terracotta Kitchen Tiles where the seal had worn down and were now dull, and the grout had darkened. I surveyed the floor and completed a test clean on a section of the floor which came out well impressing the customer who was happy for me to proceed with cleaning and sealing the floor.


Traditionally Terracotta tiled floors have been sealed with a number of products over the years including Wax, Linseed Oil and on this occasion Varnish however all these products have their disadvantages and don’t compare to modern sealers which are designed for the job.

Cleaning a Dirty Terracotta Tiled Kitchen Floor

The first day was spent trying to get the Varnish off the floor which somebody had used on the floor as a sealer; Varnish is easily scratched by furniture, so I certainly wouldn’t recommend it. I worked out however that it could be scrubbed off once coated in a combination or Tile Doctor products Pro-Clean, Remove and Go and Nano-Tech HBU which would be left to soak in for a while and then softened with steam.

Mechanical assistance from a buffing machine fitted with a large black scrubbing pad helped reduce the amount of elbow grease that was required and once I was happy the tiles were clean the now soiled solution was rinsed off with water and extracted using a wet vacuum.

The next day and with the floor now clear I was able to see those areas that needed further re-treatment and also turn my attention to the grout which was cleaned using more cleaning solution worked in with a stiff narrow grout brush that gets into the grout lines. Once I was completely happy with the floor its was given a final rinse with water to remove any trace of cleaning products and then dried with a wet vacuum to remove as much moisture as possible.

Sealing a Dirty Terracotta Tiled Kitchen Floor

It’s important that the tiles are dry before sealing so I left the floor to dry out for three days before returning to seal them. No Varnish this time of course, Tile Doctor has a range of sealers for every type of situation and what I find works best on Terracotta tiles is a single coat of Tile Doctor Colour Grow topped off with multiple coats of Tile Doctor Seal and Go.


Tile Doctor Colour Grow is an impregnating sealer that penetrates into the pores of the clay protecting it from within whilst enhancing colour whilst Seal and Go completes the sealing process and adds a nice sheen to the look of the tile.


As you can see from the final photographs the floor looked really good and the customer gave me top marks for feedback.
