To clean grout we normally recommend a good scrub with Tile Doctor Pro-Clean which is an strong alkaline product, in some cases however the staining cannot be removed completely and the only thing your can do with the exception of re-grouting is to re-colour the grout with a Grout Colourant which are available in ten popular colours.
In the case of this bathroom at a house in Paisley near Glasgow both the floor of the bathroom and the shower wall tiles were in need of a refresh and after a review of possible solutions is was agreed the easiest thing to do would be to re-colour the floor grout with a Light Grey colourant and the wall tiles with a White colourant.
Cleaning and Colouring Grout
The first step before grout colouring is to give the grout a good scrub with Tile Doctor Pro-Clean to get it as clean as possible before applying the colourant. The grout was then rinsed and then dried ready for the colourant to be applied. You may be surprised to hear but we often find the biggest cause of staining to grout are the dyes contained in soaps and shampoos.
Once the grout is ready it’s a straightforward process of applying the colourant evenly along with thin coats along the grout line working the brush backwards and forwards whilst minimising the amount that gets on the tile. We were not changing the colour of the grout substantially so one coat of colourant was sufficient for both sets of tile.
With two colours being applied we were careful to ensure different brushes were used for each job to avoid any contamination and once the job was complete a damp pad was used to remove excess product from the tile surface.
As you can see from the photographs the difference was immediate, the other advantage of the colourant is it forms a barrier over the grout protecting it from staining and making it easier to clean going forward.
This particular Slate tiled floor was installed in the kitchen of a house in Huston, that’s Houston near Glasgow not the city in Texas. This is another example of a natural stone floor was overdue a deep clean and re-seal, any remaining sealer on the slate has worn off and the tiles have become dull and stained.
Cleaning Slate Floor Tile and Grout
First we stripped any remaining sealer from the slate tiles by applying a strong solution of Tile Doctor Pro-Clean which was left to soak in before being worked into the stone using a black pad on a rotary bonnet machine; the resultant soiled cleaning solution was then extracted using a wet vacuum. This process was repeated three times to make sure all the sealer and dirt was completely removed and extracted.
After this we focused on cleaning the grout using more Pro-Clean this time worked in using a stiff grout brush by hand. Once done the floor was given a thorough rinse using clean water again using the wet vacuum to remove the water and get the floor as dry as possible.
Changing the Colour of Grout
We then left for the evening to allow the floor to dry off overnight and returned the second day and coloured the grout to dark grey using a grout colouring kit to achieve an even grout appearance. This is rather painstaking work but the effect is well worth the effort, then once that had dried we gave the floor a quick clean using Tile Doctor Neutral Cleaner.
Sealing Slate Floor Tiles
After allowing to dry overnight again, we came back the third day to seal the slate tiles for which we used six coats of Tile Doctor Seal and Go which is a water based sealer (no smell) which added a nice sheen to the tile and gave the desired finish.
Slate is a hard-wearing product ideal for floors however it does need a sealer to bring out the best in it and sealers do wear off after a few years and this had happened with the Slate tiled floor in this post. The floor was now looking dull and the grout had also discoloured so time to call in Tile Doctor to breathe new life into the tile and grout.
Cleaning a Slate Floor
It’s not a good idea to apply a new sealer on-top of existing as it can affect the final result so the first task was to strip back the floor to the natural stone giving the Slate and Grout a thorough clean in the process.
To do this a strong solution of Tile Doctor Tile Doctor Pro-Clean was applied and left to soak into the floor for about 20 minutes; Pro-Clean has a strong alkaline base so it’s safe to use on Stone as opposed to a weak acid cleaner. After twenty minutes it was worked into the slate and grout using a low speed bonnet machine fitted with a black scrubbing pad with the excess extracted using a wet vacuum.
This process was repeated three times to make sure all the old sealer and dirt was completely removed and after this the grout was cleaned by hand using more Pro-Clean and a stiff brush. Once done the whole floor was then neutralised with more water to ensure there was no trace of cleaning product remaining on the floor prior to sealing.
The floor was left to dry off overnight and returned the second day to colour the grout to dark grey which made a big improvement to the overall look of the floor; the grout colours we use come in 12 colours so we can usually find one that matches the customers’ requirements, once applied they also form a great barrier preventing future staining. Once the colourant has dried the floor was given a further clean with Tile Doctor Neutral Cleaner which is an everyday cleaning product we recommend for sealed floors.
Sealing a Slate Floor Sealing
The floor was left to dry and we came back two days later to re-seal the tile for which we used five coats of Tile Doctor Seal and Go which is a great sealer for Slate tiled floors as it leaves a low sheen finish whilst providing excellent stain protection. I should mention that Seal and Go is also a water based sealer so it doesn’t leave a smell whilst it’s drying.
We left the floor to dry overnight again and came back the third day to seal the Slate tiles for which we used six coats of Tile Doctor Seal and Go which give a subtle shine to the tiles and matched the customers requirements.
This shower cubicle was installed in the main bathroom of a house in Bishopton where the grout had become quite grubby and the Ceramic tiles were looking quite dull. The owner was thinking about re-tiling the bathroom and thought they would give us a call first to see if we could refresh the look without the expense.
Cleaning Ceramic Tile and Grout
We started by spraying the tiles with Tile Doctor Oxy-Pro which is a strong high-alkaline cleaner especially formulated and packaged for cleaning showers. The spray delivery is important as mixing the cleaning product with air makes it lighter and helps it cling to the tile and grout. The Oxy-Pro was left to soak into the tiles for around 15 minutes before being scrubbed into the tile and grout using a stiff grout brush. This action cleaned up the grout and tile nicely removing stains from shampoos and soaps etc.
Removing Mould from Grout
The grout was looking much improved but there was however some evidence of mould remaining which needed dealing with. To tackle this we used Tile Doctor Mould Away which is designed to remove mould off Silicone and Grout. It’s very easy to use, you simply spray the Silicone or Grout to be treated with Mould Away then leave to soak in for five minutes and then scrub with a brush and rinse with water repeating the process until the mould has disappeared.
It took a fair amount of manual effort but the results were well worth it as you can see.
