Balham

The photographs below show the condition of a heavily soiled Terracotta tiled kitchen floor at a residential property in Balham, SW12, which I was recently commissioned to renovate. The client had several outstanding tasks related to the renovation of the property, but the kitchen floor was the most urgent due to its significant level of soiling. The client described the condition of the floor as “VERY dirty” and in immediate need of professional attention.

During an initial site visit, I conducted a thorough inspection of the floor. It became clear that the contamination was largely the result of recent renovation work carried out by other tradespeople. A cleaning test confirmed that the floor would respond positively to deep cleaning. I also identified that a sealer had previously been applied, but to restore the floor to a satisfactory standard, a deep and intensive cleaning process would be necessary, followed by resealing.

Following this assessment, I prepared a detailed quotation for the renovation work, which was approved by the client. A suitable date was then agreed for the commencement of the job.

Deep Cleaning a Terracotta Tiled Kitchen Floor

Upon returning to the property, I began the renovation by carrying out a deep cleaning of the Terracotta tiles and grout lines. For this, I used a strong dilution of Tile Doctor Remove and Go, combined with Nanotech HBU to maximise effectiveness. The solution was agitated into the surface using a rotary floor machine fitted with a coarse carbide brush.

The floor was then rinsed thoroughly, and the resulting slurry extracted using a wet vacuum. I carefully inspected the tiles and grout after the first pass, and any areas with persistent staining were retreated using the same method. To ensure a thorough clean of the grout lines, I applied a strong solution of Tile Doctor Pro-Clean, which I worked in manually using a hand-held scrubbing brush until the grout reached an acceptable standard.

The floor was rinsed multiple times throughout the cleaning process, with each rinse followed by slurry extraction using the wet vacuum. After the final rinse, I used the vacuum once more to remove as much residual moisture as possible.

Sealing a Terracotta Tiled Kitchen

Before sealing, I tested the floor with a damp meter to ensure it was completely dry. Once confirmed, I applied several coats of Tile Doctor Colour Grow. This sealer contains a colour-enhancing formula that accentuates the natural orange and red tones typical of Terracotta.

Tile Doctor Colour Grow is an impregnating sealer that penetrates the surface of the tile, filling the pores to prevent the ingress of dirt and moisture. This ensures easier maintenance and provides long-term protection, while preserving the natural matte appearance of the tiles — an important requirement expressed by the client.

The transformation was remarkable. The client was extremely satisfied with the result, stating that the floor now “looks like new.”

For ongoing maintenance, I recommended the use of Tile Doctor Neutral Tile Cleaner. This pH-neutral product is specially formulated to clean sealed tiles without degrading the protective sealer. I advised against using standard household cleaning agents, as many are too aggressive and can compromise the integrity of the sealer over time.
