Grout Cleaning

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

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.


Black Slate Floor Renovation Glenridding Ullswater

Black Slate Floor Renovated in Glenridding Ullswater

I thought I would share the details of this Black Slate floor renovation we recently completed in Glenridding in Ullswater. Slate is a popular choice for flooring in the Lake District due to its abundance in the area so I’m sure it will be relief to some to know that it can be restored regardless of the state it gets into.

This House was actually an old Miners Cottage based in the Valley of Glenridding and the Black Slate was actually from the mine itself. After nearly two hundred years of use the old floor was still in good structural condition although the pointing had perished in many areas and needed replacing

Unless it’s being completely removed, I always recommend putting old floors like this back into use. Reason being the lack of a damp proof membrane which if in place would prevent moisture rising through the floor; old floors like these don’t have a DPM so its best to maintain them and let them breathe so moisture can evaporate at the surface. Cover them up and you risk damp building up under the floor where it can reach out to the walls.

Re-Pointing Black Slate Flagstones in the Lake District

The first step of the renovation was to knock out the remaining pointing with an 8lb Titan hammer drill fitted with a chisel attachment. The debris was cleared and new pointing applied. For this I like to use a product called VDW800, we don’t sell it at Tile Doctor but its easily sourced on-line. and for my money it’s the best pointing product on the market. It can be used inside or outside, it’s totally waterproof but it’s also breathable, flexible and comes in four different colours.

Unlike Lime pointing this product fully hardens after twenty four to forty eight hours (depending on temperature) and it doesn’t wash out. Once the pointing was completed, we left it to dry overnight.

Next, we gave the floor a general clean with Tile Doctor Remove and Go which was sprayed onto the stone floor and then after about ten minutes worked in with a Black scrubbing pad fitted to a rotary floor machine. This is good for softening up paint and old sealers so they can be rinsed off with water and extracted with a wet vacuum.

Deep Cleaning Black Slate Flagstones

The next day our attention turned to the Slate flagstones which had been stained by all types of material that had accumulated over the years; this included paint, old sealer, and bits of Varnish to name a few, you name it this floor had it.

To renovate stone when it’s this bad they only option is to use a technique we call Milling that uses very abrasive “Milling Pads” encrusted with industrial diamonds to grind off the surface to reveal new stone underneath. It also makes the stone much more smoother to walk on and as a result easier to clean going forwards. A further benefit is a smoother stone requires less sealer. The milled floor combined with the new pointing should result is an almost new floor.

The great thing about offering this service is that the customer retains the look and feel of the original floor which in this case ran from the front room, passage, and Kitchen area.

The milling pads are applied using a floor buffer which is weighted to ensure a strong contact with the stone. It does generate a lot of dust though so we use water to contain the dust and help with lubrication. Once done the floor is rinsed with more water and the resultant slurry extracted with a wet vacuum.

The next step is to apply a sealer however the Slate needed to be completely dry before we could do that so it was left to dry out for a few days.

Once the Stone had dried sufficiently (they never dry fully in old buildings without a DPM) the weather had changed for the worse and we had a full blizzard has arrived with snow and ice etc. It wasn’t ideal for sealing but the sealer we had chosen to use on this occasion copes well with damp due to it having an oil base and is rated for external use.

The sealer used is called Tile Doctor X-Tra Seal and is excellent on Black Stone as all Black Stones get their colour from the oil content inside the stone. The sealer fills up the pores in the stone resulting in a lovely dark sheen. The only disadvantage is its quite an expensive product however only one coat was needed and, on this occasion, it was the only sealer I would have recommended for this floor.

Once complete the floor looked completely transformed and should look great from many years to come. Assuming they and future owners of the property look after the floor it should never need Milling again just a deep clean and fresh seal ever five to seven years.

On the subject of maintenance, we took time to discuss after care cleaning before leaving and informed them to stay clear of using a steamer as this will damage the sealer. To clean this floor I recommended they use Tile Doctor Neutral Clean which is a mild but effective specialist tile cleaner that’s Ph neutral and comes in a concentrate so a little goes a long way. Naturally there are many tile cleaning products available in the market but you do need to careful as many are bleach bases and can harm the sealer, even washing up liquid which is a very good degreaser will damage a stone sealer.

Semi Riven Green Slate Renovation Keswick

Semi Riven Green Slate Floor in Keswick

The owner of this property in Keswick requested a visit to take a look at their Green Slate kitchen floor. The Slate tile was the Semi Riven variety which works well in a Kitchen due to the rough surface being anti-slip however that rough surface can also trap dirt.

Some areas needed a deep clean and other areas were still in good order but because the client was not sure of which sealer, they had used in the past it would be necessary to treat all three floors with the same process and strip off the original sealer first. All were interconnected and if we only covered one room and not the next there would be a difference in the finish between the floor areas.

Although the Green Slate floor was the main issue, I noticed that they had a small Quarry tiled hallway at the front of the property which looked tired, so I offered to renovate that as well. The process for cleaning and sealing Quarry tiles is virtually the same as Slate so it made sense.

Before we do any work at all you will notice on one of the pictures that we apply a thin coat of clear silicone to the bottom of the units where it meets the slate, this stops water getting underneath and causing a capillary action forming and blowing the wood, or in this case MDF which is very absorbent more so than standard wood and will blow within 10 to 15 minutes of water being left to stand underneath it. Using the silicone stops this problem completely (assuming no gaps have been left for water to seep into).

Working in three separate zones I started by removing the original sealer with the application of a medium dilution of Tile Doctor Remove and Go. This product is a sealer and coatings remover. My method was to let the solution soak into the tiles for about ten minutes and then work it in using a coarse 200-grit milling pad fitted to a rotary buffer. These pads really get into the rough surface of the slate stripping off the old sealer and getting the tile clean at the same time. The slurry generated was rinsed away with water and then extracted with a wet vacuum.

Next the Slate was treated to an acid rinse using Tile Doctor Grout Clean-Up. This process removes mineral deposits including old grout smears and really shows the tile at its best. The acidic nature of the product will also serve to neutralise the alkalinity in the tile caused by the application of Remove and Go earlier. Additionally Remove and Go is designed to strip off sealers, so I didn’t want any trace of it hanging around in the pores of the stone.

After a thorough rinse and extraction, the floor was left to dry off overnight.

I came back the next day to apply a fresh sealer to the floor checking first it was dry by taking a few moisture readings with a damp meter. Slate and Quarry tiles are porous, as it’s the top layer of Grout and without a sealer in place dirt can become lodged in the pores making it very difficult to lean.

The moisture readings confirmed the floor was dry enough to be sealed however my client was still unsure of the finish they wanted so before starting different sealers were applied on different parts of the floor so they could get an idea of how it would look.

After reviewing the results Tile Doctor Colour Grow was chosen, it’s a matt effect sealer which lifts the overall finish of the stone by enhancing its natural colours, it also worked well on the Quarry tiles and will provide many years of protection.

The client was very happy with the finished floor and especially how improved the grout looked which was an additional bonus. Before leaving I took time to explain how to maintain the floors going forward for which I always recommend a mild tile cleaner such as Tile Doctor Neutral Tile Cleaner. Many of the products you find in supermarkets are simply too strong for cleaning a sealed floor and will strip the sealer off prematurely.

Textured Ceramic Kitchen Floor Tile Grout Colouring Keswick

Textured Ceramic Tile and Grout Clean and Colouring in a Keswick Kitchen

The owner of this property in Keswick had twenty-year-old Textured Ceramic Tiles installed in the Kitchen which have the advantage of increasing grip. However, the textured nature of the tile has the disadvantage of trapping dirt, making them difficult to keep clean.

More importantly the Grout which was originally white had also trapped turned causing it to darken over the years and it had now turned black as you can see in the photos. Although waterproof the top layer of grout is cementitious and slightly porous and so it does attract dirt over time.

The floor now needed a thorough clean to remove the trapped dirt from the textured tile and the grout. Whilst we can deep clean the grout using products like Tile Doctor Pro-Clean it won’t prevent the problem from happening again. We therefore recommended applying a grout colourant to the floor which adds a protective epoxy barrier over the grout in the colour of the client’s choice. This makes the grout look new and fresh and of course protects the grout going forward, its also much easier to keep clean.

Deep Cleaning Textured Ceramic Tile and Grout

To start we used Tile Doctor Grout Colourant Pre-Treat Cleaner which was scrubbed into the floor with a particular focus on the grout. This cleaned up the ceramic tiles and grout and being slightly acidic etches the surface of the grout to improve the bond with the colourant. I always recommend doing this as it does achieve a superior bond with the colourant helping it to last.

After the grout was pre-treated, cleaned, and dried using air blowers and a heat gun I started the lengthy process of applying the grout colourant. The kitchen was a good size and there were lots of grout lines that needed colouring, so it did take some time.

The colourant comes in ten different popular colours and on this occasion, I advised the client that Sandstone Grout colourant would work best. To prove my point, I demonstrated how it would look on a few of the grout lines so they could get a better idea of how it would look.

They agreed with my choice and I spent the rest of the day meticulously applying two coats of Sandstone Grout Colorant, which is tedious work but very rewarding. You can see the progress we made during the day on the pictures below, the only issue encountered was a free flying Quaker parrot which had a habit of dive bombing every time someone stood up!

We finished the clean and left the client with a bottle of Tile Doctor Neutral Cleaner for future cleaning of the floor. It’s very important not to use bleaching agents on the grout colourant or it will fade, you will find bleaching agents in all types of household products.

My client was very happy with the completed work and left the following feedback:

“Russell and his mate (sorry I didn’t catch his name) arrived on time and made an excellent job of rejuvenating our kitchen floor in the day even though this required a late finish for them. They were no trouble to have in the house.”

It is always nice to get positive feedback from a customer, feedback is like icing on the cake.

Textured Porcelain Tile with Charcoal Grey Grout in Kendal

Changing the Grout Colour used on Porcelain tiles in Kendal

A customer in Kendal requested that the colour of grout installed on 20m2 newly laid textured Porcelain tile floor was changed; the tiler had used a Sandstone coloured grout and they were not happy with the colour or the grouting in general which looked patchy. I recommended the use of an epoxy Grout Colouring product that re-colours, seals and rejuvenates existing grout joints and comes in twelve different colours and after showing the customer the different colour options they picked Charcoal Grey.

Applying Grout Colourant

I did a test area so they could see how it might look under the lights which went well and so I started to apply the grout colouring to the whole kitchen floor completing small areas until the entire floor was covered and taking care not to get any on the Porcelain tile as the textured surface makes it difficult to remove and requires the use of an white abrasive scouring pad. Normally you have to use a Pre-Treater product on the grout before Grout Colouring however this grout was new and so this step was unnecessary.

This job took me one day and only required one tube of Grout Colourant. The owner was extremely happy with the result will now have a fairly maintenance free tiled floor as Porcelain tiles are very hard wearing and the epoxy grout colourant acts as a barrier and therefore unlikely to discolour.
