Refreshing a Very Dirty Sandstone Tiled Floor

This Sandstone tiled floor with Limestone coloured grout in Cardiff was laid in 2006 and had now discoloured with wear and tear and had almost turned black in places which I suspect was due to no sealer being applied after installation.

I carried out a cleaning sample using Tile Doctor HBU Remover, which is a strong cleaning solution, applied it to one tile in the utility room and the dirt lifted off with remarkable results; I then dried the tile with a heat gun to show the customer the results which she was happy with.

For the rest of the floor I started by wetting the surface and carried on treating it with more HBU remover diluted 50% with Tile Doctor Pro-Clean which made it thinner and more effective for deep cleaning. Using a stiff sweeping brush with bristles about half inch long (well broken in for this type of job) I then scrubbed away at the tiles and then the grout joints using a small hand held scrubbing brush which I always find is more effective than a machine which can make a lot of mess and can be overly aggressive. I cleaned the tiles in 5m2 sections rinsing each section four times to ensure there were no trace of cleaning solutions left behind. When finished the floor was left to dry for two to four hours and I tested for moisture knowing it would be ok but always worth checking.

I sealed the Sandstone with four coats of Tile Doctor Colour Grow which is an impregnating and colour enhancing product which will protect the floor for many years to come.

I tested the floor with a water test to ensure it was fully sealed, this is a simple test whereby you check to see if drops of water applied to the surface form beads on the tile. The end result was incredible as you can see the tiles looked as good if not better than the day they were cut from the quarry, and the Colour Grow certainly enhanced the true colours in the stone.

Deep Cleaning Sandstone Tiles in Leicestershire

These Sandstone floor tiles installed in a house in the market town of Uppingham had become completely discoloured and much darker over the years, especially in that well-trodden kitchen triangle between the sink, cooker and fridge. They were now well overdue for a deep clean and re-seal and so we were asked to come and strip back the floor and re-seal it.

Given the discolouration of the tiles it was likely this was caused by more than just ingrained dirt and that multiple products had been applied to the tiles so I decided the best course of action would be to strip the floor back to its original condition first. With this aim I applied a dilution of Tile Doctor Remove and Go which is a sealer and coatings remover which lives up well to its name. It was left to soak into the tiles for a good thirty minutes before being worked using a rotary machine fitted with a black scrubbing pad. The soiled solution was rinsed off with clean water which was removed with a wet vacuum; stubborn areas were then re-treated in the same way and once I was happy with the general condition of the floor it was given a thorough rinse with water to remove any traces of cleaning product and then left to dry overnight.

We came back the next day and after checking the floor was dry proceeded to apply the sealer which it was so we proceeded to seal the Sandstone with a couple of coats of Tile Doctor Colour Grow. Colour Grow is an impregnating sealer that penetrates deep into the stone, enhances the natural colour in the stone and provides good surface protection, the customer was also after a matt finish and Colour Grow matches the requirement.

Removating Old Flagstones in Cumbria

We received a request to take a look at these Sandstone flagstones at a house in Grange over Sands, the request implied all was required was a usual clean and Re-seal however once we took a look at the floor it was obvious a lot more was involved and the floor was in need of restoration work including Sandstone floor restoration including grout replacement and paint stripping

To get the floor clean I decided to apply a strong dilution of Tile Doctor Remove and Go combined 50/50 with NanoTech UltraClean to give it more cleaning power. We normally use Remove and Go to remove old sealers but it works just as well softening up paint splashes so they can be removed. It was left to soak into on the flagstones for a good twenty minutes before being scrubbed into the tiles with a rotary machine fitted with a scrubbing pad. The resultant slurry was removed using a wet vacuum and the floor washed down so we could get an idea of the improvement in the floor. There were quite a few stubborn areas so the whole process was re-done until I was happy the floor was as good as I could get it and at that point rinsed the whole floor down again with clean water to neutralise the floor before dealing with the missing and loose grout which was replaced with a close a colour match as possible before leaving for the evening so the floor could dry overnight.

We came back the next day and tested the floor with a damp meter in a few different locations to make sure no dampness remained in the stone. The sandstone was dry so we proceeded to seal the floor with Tile Doctor Colour Grow which is an impregnating sealer that occupies the pores in the stone preventing contaminates becoming ingrained there and also as its name suggests brings out the colours in the natural stone.
