Terracotta Tiled Kitchen Floor with Severe Grout Haze Problem Treated in Cogenhoe

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.

Removing Grout Haze from Terracotta Tiles

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.

Travertine Tiled Kitchen With Badly Stained Grout Cleaned in Northampton

Earlier this month I was in the town of Northampton, to see a client who had reported a problem with her Travertine kitchen tiles. Basically the grout between the tiles was badly stained, to the point of appearing almost black.

The Travertine tiles were also in need of some maintenance, and so I was commissioned to provide a clean, polish and a fresh seal. Travertine is a popular choice for kitchen flooring due to its relatively high durability and distinct features. My task was to get this floor back to looking its best.

Cleaning badly stained grout

My priority was to address the badly stained grout so I cleaned the grout lines by hand using a combination of hand brushes and Tile Doctor Grout Clean-Up. The surface was pre-wet with water, before a solution of Grout-Clean Up and clean water was applied to the surface. The brushes were then used to agitate the solution. Grout Clean-Up contains a mix of concentrated phosphoric acid and cleaner designed to penetrate below the surface of the grout to remove grout stains, smears and mineral deposits.

As you can see from the photos, Grout Clean-Up made an immediate difference to the appearance of the tiles. This product is suitable for use on masonry and acid resistant surfaces. After completing the clean, I gave the floor a thorough rinse to neutralise the floor after cleaning and removed as much of the water as possible using a wet vacuum.

Burnishing Travertine tiles

Following this, I paid attention to the tiles themselves, cleaning them to achieve a polished effect by using a system of burnishing pads. Tile Doctor burnishing pads comprise a set of four pads varying in grit type, from Coarse and Medium to Fine and Very Fine. I applied all four pads in turn to the floor, stopping to rinse the floor in between each. The result was a high quality polished finish.

I then left the floor to dry completely overnight, before commencing the seal the next day. My choice of sealing product was Tile Doctor Colour Grow which is a colour intensifying sealer that both enhances the natural appearance of the stone and provides a durable surface seal.

My client was very pleased with the finished product, and left the following comment on the Tile Doctor feedback system: “efficiently done”, yielding “good results”.
 
 

Dealing with Stained Grout in a Travertine tiled kitchen in Northamptonshire

Cleaning up newly installed Grout in Titchmarsh

This customer from Titchmarsh near Kettering was unhappy that the Porcelain floor tiles that were installed in her kitchen six months prior were proving difficult to clean and that the grout line had turned from a grey to black and whatever she tried she just could not keep this floor clean. On inspection I soon discovered that no or very little sealer had been applied to the Porcelain which is not unusual as most Porcelain does not require a sealer however Micro Porous Porcelain does and she should have been advised by the shop that sold her the tiles that this was the case. A quote was given which she was happy with and I returned the following week to sort the problem out.

Deep Cleaning Porcelain Tile and Grout

To protect the kitchen units I covered them in a plastic and then moved onto to deep cleaning the tiles with a dilution of Tile doctor Pro Clean which was applied and left to soak in for a while before hand scrubbing the floor on my hands and knees with stiff brushes. This did made an improvement but something stronger was required to get the grout looking better so it was back down to the floor with hand brushes again but this time I used Tile Doctor Grout Clean-Up which is an acid that can remove grout smears and mineral deposits, in the end I actually used two litres of Grout Clean-Up to restore the grout to about 95% of its correct appearance and once done I gave the floor a thorough wash down to remove any trace of product.

Sealing Porcelain Tile and Grout

This grout should have been correctly sealed from day one and luckily for the client it came up to her satisfaction otherwise the only other option would have been to use a Grout Colourant which would have been more costly but cheaper than replacing the grout altogether. Had the grout been much older this may have been the best option as I suspect the result from cleaning would have been less effective. The last step was to seal the tiles and grout using Tile Doctor Ultra Seal which is a natural look sealer that provides maximum stain protection and is recommended for use in kitchens. Before leaving I gave the client written instructions on maintenance which she found very helpful.
