Renovating a Chinese Slate Hallway Floor in Gloucestershire

This client from Cirencester got in contact about his Slate Tiled hallway floor which was now looking dull following renovations to the property by the owner who was a builder. If you have never been I can recommend you pay Cirencester visit, it’s a lovely old market town that dates to the Roman times and is incidentally is the largest town in the Cotswold District.


I arrived at the property and could see immediately that the floor had never been sealed properly and so the appearance had just got worse over the few years since it was laid. Dirt had become ingrained in the pores of the slate making it impossible to clean effectively. The client realised that the only way to fix the problem was to have the floor properly treated. We agreed a price for the work and popped a date in the diary to come back.

Cleaning a Chinese Slate Tiled Hallway Floor

As the floor was in the hallway, we needed to protect the stairs and skirting with plastic sheeting before we started. I then started cleaning the tiles with a strong concentration of Tile Doctor Remove and Go, this is a multi-purpose stripper which can remove most coatings and sealers and works best it left to dwell and soak into the stone for a long time before scrubbing it in. This also helps it work on ingrained stains and remove heavy grease build-up. My primary reason for choosing Remove and Go was to remove what was left of the sealer so after applying it to the floor I left it to soak in for ten minutes before being scrubbed it into the tiles with a black pad scrubbing pad fitted to a rotary floor buffer. The dirt soon turned the cleaning solution black and the slurry was extracted using a wet vacuum.

Next, I worked on cleaning up the grout using Tile Doctor Pro-Clean, this is good for neglected and heavily soiled areas and it makes short work of cleaning dirty grout. I had to scrub the grout by hand and once I was happy that the slate and grout was as clean as it could be the floor was given several rinses with water to remove the remaining dirt and remove any traces of cleaning products. Once this was done this completed the cleaning process, I was satisfied with our efforts and the floor was left to dry off overnight.

The next day I checked the moisture level of the stone in several areas with a damp meter to check that the floor was dry. The sealer will not cure if the floor is not properly dried out. I chose a combination of sealers to achieve the look we were after. First, I sealed with one coat of Tile Doctor Colour Grow this is an impregnating sealer that occupies the pores in the stone thereby preventing dirt from becoming ingrained there. It’s also a colour enhancing sealer that works really well on Chinese slate to highlight all the colours. Once this was dry I followed with three coats of Tile Doctor Seal and Go which is water-based blend of acrylic polymers that provides both a stain resistant surface seal and a durable low-sheen finish, which was perfect for finishing this floor.


The customers response was ‘It never looked as good as that’, and he now realised the importance of sealing the floor correctly! I love the natural patterns in this type of floor, it is one of my favourites.
