Grout Cleaning

Welcome to my Work History archive where you will find detailed examples of the cleaning and renovation of Grout carried out in Monmouthshire

Cleaning and Renovating Grout

The top layer of grout is porous and can absorb grease, dirt and limescale. Spillages such as wine, lemonades or greasy substances will cause marks and patches in the joints in the floor. Grout between wall-tiles particularly in damp areas like bathrooms will become dirty and unattractive as a result of Mould, Mildew and Limescale.

Mould is one of the most unsightly problems, which usually starts off in the wettest area of the room, this could be the bottom of the shower or bath, then starts to spread and if left unchecked could cover a large area of the wall.

Another common issue we find is a problem known as Grout Haze or Grout Smearing where a thin layer of grout has been left to set on the surface of the tile. Once grout has set it is difficult to remove.

Discolouration of grout joints in bath or shower areas due to continued use of acid formulated shampoos and soaps. This causes yellow orange and pink stains to the grout over even a short period of time. Whilst Grout Joints can be cleaned, badly stained grout may need to be re-coloured.

Protecting your grout in advance with a sealer will prevent most of these issues and although relatively unknown in the UK, protection awareness is growing. Sealing forms an invisible barrier between the grout and the surface, this will then protect your investment for years to come.

We have solutions for all the problems listed above and below you will find detailed examples of work we have carried out in the past to resolve many of these issues. It should give you some idea of what’s involved and what can be achieved with the right techniques and products.


Travertine Tiled Bathroom Floor Renovation Magor Newport

Renovating Travertine Bathroom Floor Tiles in Magor Newport

These travertine tiles were laid twelve years ago in the bathroom of a property in the village of Magor near Newport. They were supplied by Mandarin Stone however the tiler had not sealed or grouted them correctly during installation.

The client highlighted a significant crack running along 4 of the tiles starting at the bottom of the toilet and was unsure what to do about it. I suspect this was due to movement in the floor and wondered if a backer board had been used under the floor as this would usually prevent this.

The patterns you find in natural stone are unique so finding a replacement Travertine tile to match the cracked tiles was unlikely. I therefore suggested disguising the crack with a coloured filler as part of an overall renovation. They also asked me if I could regrout the entire floor as most grout lines were quite deep and below the surface edge of the tile, also the natural pits in the stone were collecting a large amount of dirt from foot traffic.

Happy to oblige I worked out a quote to resolve all the problems which was accepted, and a date set to do the work.

Cleaning a Travertine Tiled Bathroom

I began by removing as much of the existing grout as possible with a grout rake, this is slow work as you must be very careful not to chip the adjacent tiles in the process. Once complete I started on cleaning the tiles using a medium dilution of Tile Doctor Pro-Clean which was left to soak in for 15 minutes. This dwell time gives the product chance to breakdown the dirt and other contaminates before being scrubbed into each tile using a handheld brush making sure every nook and cranny was sufficiently clean. The floor was then rinsed with a sponge and brush ensuring there was no product residue left within the tiles or pits.

Once the tiles had fully dried the floor was grouted using flexible grout in a colour that closely matched the grout used on the wall tiles. Grout was also run along the crack to disguise it as much as possible. Once the entire floor had been regrouted properly, I left to allow it to go off overnight and allow the tiles to dry out further.

Sealing a Travertine Tiled Bathroom

Previously I had discussed the range of Tile Doctor sealing products with the client and what they would provide in terms of finish. It was clear they wanted to keep the look of the stone as light as possible whilst sealing so with this in mind I opted to seal the Travertine with Ultra-Seal which is a clear coat sealer that provides maximum protection without enhancing or darkening the stone.

Four coats of Ultra-Seal were applied making sure to cover all pits in the tiles and the new grout that had been installed. This sealer works by occupying the natural pores in the stone, ensuring dirt remains on the surface where it can be easily cleaned away.

Once complete I’m happy to report my client was really pleased with the result, they were worried that whole floor would have to be ripped out and replaced so much relieved to have found a better solution. I guess we really lived up to our Tile Doctor name on this occasion.

On the subject of aftercare, I left the client with a bottle of Tile Dr PH Neutral Tile Cleaner which is a gentle yet effective tile and grout cleaner that won’t harm the new sealer.

Black Slate Tiled Kitchen Floor Renovation Caldicot

Black Slate Tiled Kitchen Floor Renovated in Caldicot

I recently cleaned and sealed this small Black Slate tiled kitchen floor in the market town of Caldicot. You can see from the before image below that the sealer that was applied when the floor was installed twelve years ago had completely failed and had begun to flake away. Kitchen floors and especially small floors like this one do get a lot of foot traffic resulting in wear to the sealer, they are also subject to staining from cooking.

To restore the Slate back to its original appearance what was left of the old sealer would need to be stripped back entirely, then the tiles would need deep cleaning and resealing. In this case the customer wanted to keep the permanent wet look finish however I had a sealer in mind that would provide this.

I discussed with the client the process to get the floor cleaned and restored and created a quote for doing the work which would only take a day. Happy with the quote a date was set for the work to start.

Cleaning a Black Slate Tiled Kitchen Floor

After protecting the kitchen unit plinths from splashing I started by brushing diluted Tile Doctor Pro-Clean onto each tile and left it to dwell for fifteen minutes. This gives the product time to breakdown and lift the remnants of the remaining sealer. The solution was then agitated with a seventeen-inch 120-grit poly brush that attaches to a rotary floor machine along with more water to help lubricate the process.

Fortunately, being a small floor with large format Slate tiles there wasn’t much grout so it didn’t take too long to get the grout clean with more Pro-Clean scrubbed in by hand with a scrubbing brush.

The scrubbing turns the cleaning solution black with the dirt and old sealer released from the tile which was then vacuumed up. I noticed however that not all the sealer had been removed so I repeated this process once again until I was satisfied.

After drying the floor completely using an air mover it was evident that all the previous sealer had been removed and the floor was now ready to be sealed

Sealing a Black Slate Tiled Kitchen Floor

The customer had requested a high satin finish, the same as it looked after it was first laid. To achieve this, I applied Tile Doctor Seal and Go, applying four even coats which left the floor glistening.

The new sealer will ensure dirt cannot find its way into the pores of stone and remains on the surface where it can easily be cleaned away by the client. This allows the customer to easily maintain the cleanliness of the floor.

My customer was delighted with the results and said that it even looked better than when it was installed over 12 years ago! For aftercare I left the customer with a bottle of Tile Doctor PH Neutral Tile Cleaner which will help maintain the appearance of the floor. You do need to be careful when choosing a floor cleaning product as most are simply too strong for use on sealed tiles and will strip off a sealer with repeated use.

Green Riven Slate Floor Cleaning and Sealing Chepstow

Green Riven Slate Floor Cleaned and Sealed in Chepstow

This client in Chepstow had a beautiful Green Riven Slate Tiled floor installed in their living room some year prior but were now unhappy with its appearance. What was once a real feature of the property had lost its deep shine and now looked flat and unappealing.

The client called us in to see what could be done to put the life back in the stone and so I went over to survey the floor and come up with a renovation plan. The owner explained that the floor was sealed with a satin finish sealer and although they liked the way that looked it had deteriorated over time and now the floor looked patchy.

Green Riven Slate Floor Before Cleaning Chepstow

This is a common problem with sealed stone floors, sealers do wear off in the busiest parts of the floor and once this happens, they will lose their appearance as dirt gets trapped in the pores of the stone where its difficult to flush out with regular cleaning. The other problem we see is the use of harsh unsuitable cleaning products which can reduce the life of the sealer.

To resolve I recommended stripping off all the old sealer back to the natural stone, deep cleaning the pores and then re-sealing with a product that would give them the satin finish they had before. Happy with my proposal and quote a date was agreed for the work to start which would take two days, one to strip and clean and the other to seal.

Cleaning a Green Riven Slate Tiled Floor

Work started by stripping off the old sealer with a strong dilution of Tile Doctor Pro-Clean which was brushed over the tile and grout, and then left to soak in for ten minutes. This dwell time gives the product time to start breaking down the old sealer and dirt. The solution was then agitated with a poly brush fitted to a large buffer machine which was run over each tile several times. This process released the remaining sealer and dirt from the stone resulting in lots of soiling which was rinsed off with water and extracted with a wet vacuum.

The tile and grout were then inspected and spot treated with a hand scrubbing brush where needed. This is especially useful to get right into the grout and tight corners where a machine will struggle. This was then followed by more rinsing and extracting to remove the resultant soiling and neutralising the entire floor to remove all trace of cleaning products prior to sealing.

The floor was then left to dry off overnight.

Sealing a Green Riven Slate Tiled Floor

The next day I returned to the property and checked several sections of the floor with a damp meter to ensure the Slate had dried off and was ready to be sealed. Sealing a damp floor is never a good idea as it can affect the sealer curing and result in a patchy appearance.

Green Riven Slate Floor During Sealing Chepstow

To seal the floor four coats of Tile Doctor Seal and Go were applied which is a water-based sealer that has the advantage of not leaving a smell as it dries. This produced the appealing satin finish they were after and brought out the best in the stone as you will see in the photos. The sealer will protect the stone from everyday use and can last up to five years if maintained correctly.

After the job was completed, the Green Slate looked fantastic and my customer was beyond happy. I took time to explain how to clean the floor and recommended they use of Tile Doctor Neutral Tile Cleaner. This is pH neutral product that is effective yet won’t impact the newly applied sealer.

Farmhouse Terracotta Tiled Floor Before After Clean Seal Symonds Yat

Terracotta Farmhouse Floor Renovated at Symonds Yat Holiday Home

The pictures below are of a Terracotta tiled floor that was laid in a Farmhouse in Symonds Yat around twenty years ago when the house was being renovated. The Terracotta tiles had been installed throughout the kitchen, utility and downstairs cloakroom and were well overdue a deep clean and seal.

Symonds Yat is a beautiful location amidst the fields of Wye Valley and set on the famous River Wye and is very popular with tourists. The farmhouse has been rented out as a holiday home for some time and with the floor looking faded and dull it was not giving the best impressions with visitors which is not good when you are using the property as a business.

Terracotta Tiled Floor Before Cleaning Symonds Yat Holiday Home

I visited the property to survey the floor as the picture’s customers send you never show up all the problems. I could immediately see the tiles were indeed in need of some tender love and care, the old sealer had long since eroded away and now the Terracotta was susceptible to dirt becoming ingrained. I carried out a test clean on a small area so they could see what the result might look like. They were over the moon with the test area and amazed that how much it would bring the floor back to life. I quoted them a price which they were happy to accept, and we booked the job in for later in the month.

Cleaning/Repairing a Terracotta Tiled Farmhouse Floor

To put the life back into the floor it needed to be stripped of any remaining sealer, cleaned and then resealed. I began this process by spraying the floor with a medium dilution of
Tile Doctor Remove and Go and left it to soak into the tile and grout for ten minutes. This product is designed to strip off old sealers from tile which is important as you will find the sealer will be completely worn off in the busier parts of the floor but will still be present around the edges etc. If you don’t strip off the sealer and apply a new sealer on top you will find the result becomes inconsistent and leaves a patchy finish.

After ten minutes the Remove and Go was scrubbed into the Terracotta using a rotary floor machine fitted with a black scrubbing pad. This action removed what was left of the old sealer and after rinsing and extracting I was able to move onto the cleaning process.

This process was repeated using Tile Doctor Pro-Clean which is tile and grout cleaning product that will remove ingrained dirt. As before the product was diluted, applied to the floor and after leaving it to dwell for a short while it was scrubbed in as before. Some of the grout and corners had to be done by hand as the rotary machine can struggle to reach in places. After rinsing off with water and extracting with a wet vacuum there were a few stubborn areas that required a repeat treatment, but we soon had the floor looking clean.

After leaving the tile and grout to dry off overnight I came back the next day and checked the floor was dry with the moisture meter. The readings were fine, so I began applying the sealer. I started with a single coat of Tile Doctor Colour Grow which is a colour enhancing product that seeps into the pores of the Terracotta protecting it from within. This was followed with seven coats of Tile Doctor Seal and Go. Terracotta is very porous and does take a lot of sealer.

Once the sealer had dried the floor had a lovely satin finish that wasn’t too shiny. The client was over the moon with the restored floor and was keen for his next clients to see it.

Dull Black Slate Tiles Before After Renovation Blackwood

Large Format Slate Kitchen Floor Tiles Renovated in Blackwood

A client of ours recently moved into a relatively new property in the town of Blackwood where the black slate floor looked dull and the grout was stained. Large format slate tiles were installed though the kitchen and adjacent dining and utility room and they were keen to see if the floor could be brought back to life.

Dull Slate Kitchen Floor Tiles Before Renovation in Blackwood

I went over to survey the floor and could see that the old sealer was failing and letting dirt into the pores of the stone which was especially notable in the busier parts of the floor which had seen the most foot traffic. The solution would be to strip the floor of the old sealer, clean up the grout and reseal. I conducted a number of test cleans to work out the best way to how best to strip off the old seal and get back down to the natural stone. However, as it turns out removing the old sealer was proving to be quite a job and I was concerned that this task alone could potentially take days.

Unhappy with the way things were going I consulted the Tile Doctor help line and we deduced that the sealer applied previously was most likely a heavy duty/industrial product. My client had only just moved into the property and didn’t know the history of the floor so couldn’t help pin point what was used before. The way forward was to strip the old sealer off the floor using abrasive pads.

Now I had an efficient strategy for renovating the floor I was able to provide the customer with an accurate quote which was accepted, and we agreed a date to return and complete the floor.

Cleaning a Dull Slate Tiled Floor

To begin the restoration, I pre-wet the floor with water and using a weighted floor buffer ran a coarse 100-grit milling pad several times across each tile. This process strips the dirt and sealer off the stone slowly turning the water into a grey slurry. Once the whole floor had been treated in this way, I rinsed the slurry off the floor and extracted it using a wet vacuum. The next step was to repeat the process using a 200-grit burnishing pad which being finer closes the pores in the stone and refines the surface further.

The next step was to clean up the grout using Tile Doctor Pro-Clean which is a strong alkaline cleaner. You apply a strong dilution to the grout lines and then scrub it in with a stiff brush. Fortunately, the slate tiles were large format size so there was less grout to deal with than usual. Once that was done the tile and of course grout was rinsed again with more water and then dried again using the wet vacuum.

I have to admit the stripped slate looked pretty awful at this stage in the restoration, but we were now back to the natural stone which was clean and free of all sealers. I left the floor to dry off fully overnight confident in the knowledge that with the application of a fresh sealer it would look a lot different.

Sealing a Slate Tiled Floor

The next day I returned to the property to seal the floor. Before doing so, however, I needed to test the Slate for moisture as you shouldn’t apply a sealer to a damp floor. The results were fine, so I proceeded to apply the sealer which for this installation I used several coats of Tile Doctor Seal and Go.

I chose Seal and Go for this floor as it works well on Slate resulting in a deep durable satin finish that the customer wanted. Additionally, being a water-based product, it doesn’t leave a smell as it dries.

Within two days the floor was transformed, the grout looked much cleaner and the stone looked new. My client was very happy with the work and left the following message on the Tile Doctor feedback system.

Professional, polite and courteous. Paul went beyond the call of duty to help rejuvenate our slate tiled kitchen and utility room floor. He explained each step of the job and provided advice on aftercare and future maintenance. The results are great and I would gladly recommend the services available.

Dull Slate Tiles Rejuvenated with Deep Cleaning and Sealing in Ross-on-Wye

Dull Slate Tiles Rejuvenated with Deep Cleaning and Sealing in Ross-on-Wye

Ross-on-Wye, an area located in South Hertfordshire and close to the Monmouthshire border in Wales, is known as the “birthplace of the British tourist industry” due to the Wye Valley’s picturesque river scenery, landscapes, and castles and abbeys. It is also known for the famous Ross and Monmouth Railway, which opened in 1873 and closed in 1959, and ran through the valley.

I visited an old cottage in the area to assist a customer with restoring a Slate tiled kitchen floor. Slate tiles are particularly popular because of their versatility and durability, and truly they can be an asset to any property if the sealer is maintained correctly. Slate tiles need to be sealed to prevent dirt penetrating the pores of the stone as ingrained dirt is difficult to remove and causes the stone to lose its appearance. In this case the floor had been laid around five years earlier and the sealer had worn off in places and was wearing very thin in others. As you would expect dirt had now become ingrained in the tile and the grout had also become stained in places. Overall this problem had left the floor looking very dull and unappealing, as you can see from the photograph below.

Slate Floor Before Cleaning and Sealing Ross-on-Wye Cottage

Cleaning a Dull Slate Tiled Floor

To begin the restoration, I applied Tile Doctor Remove and Go liberally across the floor to strip away any remaining old sealer that was likely to be ineffectual and not preventing dirt from becoming ingrained in the stone. Next, I applied our strong alkaline cleaner, known as Tile Doctor Pro Clean to tackle that ingrained dirt. This was left to dwell on the floor and then agitated using a 17-inch rotary machine fitted with a black scrubbing pad.

After cleaning the floor, I rinsed the tiles thoroughly with water and used a wet vacuum to clear the area of the resulting slurry. Following this I concentrated on cleaning the grout lines using Pro Clean in combination with a wire brush, before leaving the floor to dry out completely for the next couple of days.

Sealing a Slate Tiled Floor

Later in the week, I returned to the property to seal the floor. Before doing so, however, I needed to test the floor for damp issues, especially since this was an old property and was unlikely to have a damp proof membrane installed. Running these damp tests are very important because excess moisture can cloud the sealer and damage its performance.

Thankfully, there proved to be no issues, and the floor was fine to seal. I did this using eight coats of Tile Doctor Seal and Go, which is a water based product (so no smell) that provides a durable, satin finish, and is recommended for use on a variety of tiles, including Quarry, Victorian, Sandstone and Terracotta.
