Removing Grout Smears From Terracotta Tiles

This newly installed Herringbone-style Terracotta tiled floor in a refurbished kitchen was heavily covered with patches of grout haze. The customer, who lives in the town of Cogenhoe, Northampton informed me that the tiler had supposedly sealed the floor before grouting. If this was true, the grout haze should have been very easy to remove.

However, the tiler had clearly not been entirely truthful as, when I arrived at the property to carry out a test clean, I found very little evidence of any sealer whatsoever. Nonetheless, I found that the grout haze was easily removed using a solution of Tile Doctor Grout Clean Up, a concentrated phosphoric acid cleaner which is designed specifically for the removal of haze, mineral deposits and efflorescence.

These Terracotta tiles were very pitted and the original tiler was correct to fill the small holes with grout to complement the rustic look of the tiles, but he should have taken the correct measures to ensure that a white misty grout haze didn’t appear over the whole area!

The customer was happy for me to proceed with restoring the floor, but also very concerned that her newly installed hand painted kitchen units would be damaged by the chemical cleaning products. I assured her that I would cover them up completely and carry out all work along the plinths by hand.

Once on site, I covered the kitchen units to protect them and proceeded to mix up a solution of Grout Clean Up. This was applied firstly around the edges of the floor and scrubbed into the stone by hand using a stiff brush.

Working in areas of four square metres each so as to not the leave the product on the floor too long, I applied the solution to pre-wet the floor ready for the next part of the process. This was to apply Tile Doctor Acid Gel, our blend of phosphoric and hydrochloric acids, leave it to dwell for a few minutes has then agitate it to neutralise and remove the copious grout haze. Once each area had been treated I rinsed it with water to remove any chemicals.

Sealing Terracotta Tiles

With the entire floor treated, I installed a dehumidifier to help the tiles to dry quickly overnight. The next day I returned to the property to apply two coats of Tile Doctor Colour Grow sealer. This is an impregnating sealer which provides robust protection while also lifting the natural shades in the Terracotta.

Each coat was polished in by hand, leaving an hour for drying between coats. I then waited another hour before giving the whole floor a final polish with a buffing machine to remove any excess sealant.

The result achieved in the space of 24 hours was fantastic and the customer was exceptionally pleased. Despite the severity of the grout haze problem, the combination of the right products allowed me to handily resolve it. The addition of a properly applied and top quality sealer will help to ensure the floor is protected from staining, something which is essential in a kitchen.

Restoring the Appearance of Grout in Preston with a Colourant

Well maintained grout is fundamental to achieving a great looking tiled floor, whatever your choice of tile or stone. Even if the tiles themselves are in reasonably good condition, dirty and damaged grout lines can really upset the overall appearance of the floor.

Such was the case with this Ceramic Terracotta tiled floor in the bustling Lancashire town of Preston. The property owner recently had a new kitchen installed, but chose not to have new tiles fitted since the original tiles (dating back a good 15 years) were still in fantastic physical condition, with no chips or breaks. This is quite surprising considering that the kitchen is typically one of the main areas of traffic in any house however Ceramic and Porcelain tiles are very durable.

The grout, however, told a different story: it was very dirty and even missing in parts. Over the years it had come away and was replaced with new grout, however, this had left the whole floor with a displeasing patchy finish. Upon closer inspection it also became clear that the tiles themselves could do with a deep clean. I stepped in to discuss what could be done to improve the appearance of the floor and recommended a deep clean and grout colouring.

Cleaning Ceramic Terracotta Tiles and Grout

Tile Doctor Pro Clean, a versatile high alkaline cleaner, was my choice of product for removing the dirt from the tiles. I applied it liberally across the floor before scrubbing it in with a scrubbing pad fitted to a rotary machine. Pro Clean is a go-to product for the removal of dirt, stains and other muck on most kinds of natural stone floor, and is capable of dealing with small amounts of soil to heavy buildup.

Once the tiles had been cleaned I turned special attention to the grout. I cleaned it with a product called Grout Colourant Pre-Treatment Cleaner, which is slightly acidic to break down ingrained dirt and tackle inherent grout smears, while ensuring that grout colourant bonds to the grout once it is applied.

The job took two days to complete as it was quite a large floor stretching into several rooms. The floor also needed to dry off overnight once I had completed the cleaning process, so I decided to call back the next day once it had dried completely. Upon my return I proceeded to colour the freshly cleaned grout by applying one coat of natural grey colourant. Sometimes two coats might be required for blending purposes, but not on this occasion.

The customer was very happy with the results. She had, in fact, thought of ripping up the old tiles as part of the kitchen restoration, but she decided not to since she really likes the tiles. A restoration by the Lancashire Tile Doctor was the appropriate and much less expensive choice!
