Slate Tiled Wet Room Treated for Grout Haze and Restored in Sevenoaks
A builder had made a real mess of this customer’s new Slate tiled wet room. When installing any new natural stone tiles, it is always recommended to apply the sealer before grouting, since – as was the case here – the porosity of the stone can cause the grout to stick with to the stone, leaving a terrible blotchy and uneven appearance.
Restoring the appearance of a Slate Tiled Wet Room
To begin, I had to tape up all the chrome and metal fittings found around the bathroom to stop them coming into contact with the cleaning products. I them started the restoration by applying Tile Doctor Acid Gel, which is a PH1 blend of Phosphoric and Hydrochloric acids for the removal of grout haze.
As it comes in a gel form, this product is especially effective on vertical or sloped surfaces, where more dwell time is required. A liquid product would, of course, simply run off the tiles. So, working on small areas at a time, I allowed the gel to dwell for around five minutes, before agitating the solution with a pan scrubber, and rinsing the gel off with water. Once I had completed this process on the whole of the wet room, I allowed the tiles to dry out before repeating the process on some of the areas suffering from thicker smears of grout.
Sealing Slate Wet Room Tiles
When I was happy that I had removed all of the grout smears, I ensured that all the tiles were dry before applying Tile Doctor Stone Oil. This product is an easy-to-apply, pre-polish impregnating sealer which is ideal for low porosity stone and also suitable for more porous stone, such as Terracotta. It is also specially designed to enhance the natural colours and textures of tiles, and improve mechanical strength once cured. The oil is particularly effective when used on dark stone, like this Slate, as it really helps to deepen the colour.
I returned the next day to seal the tiles completely using one coat of Tile Doctor Ultra Seal to lock in the Stone Oil applied the previous day. Ultra Seal is a premium, no-sheen, natural-look, solvent-based penetrating sealer formulated to provide maximum stain protection. It allows moisture vapour transmission and is an excellent grout sealer.

Reclaimed Quarry Tiles Patio Restoration in New Cross, SE London
This customer based in New Cross South East London had a significant problem with their patio. Their home is a period Victorian property so when choosing a stone for the patio, they bought reclaimed quarry tiles to marry up with the period of the house, and proceeded with their DIY project. Unfortunately they were not aware that quarry tiles are porous until sealed, and grout left on the tile and not wiped off immediately, will leave a grout haze or in this case stick to the tile altogether.
Cleaning Patio Quarry Tiles
Satisfied with the results of the test clean I proceeded to clean the rest of the floor. For this I used Tile doctor Grout Clean-Up which contains concentrated acid and is designed to penetrate below the surface to remove grout smears; this was diluted 1 to 1 with water which is a very strong mix. I sprayed the solution onto the tiles, working 1sqm at a time, leaving it to dwell on the tiles for a few minutes before scrubbing the tiles by hand with a rough pan cleaner. I then rinsed the area off with water and used my wet vac to remove the soiled solution. The strong mix had the desired effect on the Quarry tiles but it was necessary to go over the area again after spotting some of the worse stains the first application had missed. Happy with the result, I carried out this process across the rest of the patio, working 1 sqm at a time.
Sealing Kitchen Quarry Tiles
When I was finished the customer was very happy with the result, and now had a patio they could use. The customer was keen to carry on with their DIY project, and wanted to seal the patio themselves, so I advised them to use Tile Doctor Colour Grow, which is a colour intensifier and impregnated sealer; this will both protect and enhance the reclaimed quarry tile into the future.

Cleaning and Removing Grout Haze from a Quarry Tiled floor in Kemsing, Kent
The attached pictures are of a Quarry Tiled floor in a kitchen and family room of a cottage in Kemsing, Kent. The cottage was undergoing a full renovation and extension, and the quarry tiled floor was recently installed, however it was not sealed prior to grouting, and a grey grout haze was now sitting across the whole floor. Quarry tiles are highly porous and if not sealed before grouting the grout sitting on the tile soaks in leaving the colour of the grout as a haze over the tile.
Cleaning Quarry Tiles
There had been a number of tradesmen working constantly on the premises so it was difficult to tell what was grout haze and what was builders mess so I the first job was to give the floor a good clean. For this I used a strong mixture of Tile Doctor Pro-Clean diluted with water in a 3:1 ratio. I also added a squirt of Tile Doctor NanoTech Ultra-Clean which is an abrasive clean cleaner and processed to apply the solution to the floor. I left the solution to dwell on the floor for a short while and then scrubbed the floor using my weighted floor scrubbing machine fitted with a black 17inch scrubbing pad. The cleaning residue was removed using a wet vacuum and we could now see all the grout haze quite clearly.
Removing Grout Haze from Quarry Tiles
To remove the grout haze one part Tile Doctor Grout Clean-up was mixed with three parts water and poured into a spray bottle; Grout Clean-up is a product specifically designed for removing grout haze. This was then sprayed onto the floor, covering an area of around 1m2 and spread so it covered the grout haze evenly. This was allowed to dwell on the tile for three to four minutes before I agitated the solution by hand with a pan scrubber and water. This was then vacuumed up before I took a scrubbing brush and clean water from another bucket and scrubbed the area, before again vacuuming up. This ensured that all the formula had been cleansed from the floor; this process was repeated across the whole floor, working on 1m2 at a time and then left to dry ready for sealing.
Sealing Quarry Tiles
The floor was now ready for sealing; Quarry tile floors can accept two types of sealer, a topical sealer or an impregnated sealer. I usually recommend Tile Doctor Seal & Go for Quarry tiled floors which is a Topical sealer as it is easier to maintain. On this occasion however the customer wanted to wait until they had completed decorating and was happy to seal the floor themselves, so I gave them advice on what sealers to use and how best to use them and left them to it.
