Deep Cleaning Porcelain Floor Tiles at a Hospital

Although we do work on a lot of residential floors we also get commercial work such as the following request to deep clean Porcelain floor tiles in the high-traffic entrance area of the NHS Cancer Ward in Cottingham, near the city of Hull.

The Porcelain floor itself was quite large, measuring 170 square metres, and was in need of a thorough clean. The Porcelain tiles were Italian with a cement grey grout line, in addition, they had been laid in sections using a plastic Schluter Systems expansion joint. As you can imagine, the unit has a lot of patients walking around, along with doctors, nurses and other staff. Consequently, my contact at the NHS requested that we conduct the work at night, as this is the quietest time of day and therefore both risk and disruption are minimised.

Cleaning the Porcelain tiled floor

I started the job off with a deep clean, using a solution of Tile Doctor Pro-Clean diluted with water, the dilution was roughly thirty per cent Pro-Clean to seventy per cent water. This strength of solution was sufficient enough to lift the ingrained dirt and stains out of the Porcelain tiles. Pro-Clean is a very versatile alkaline cleaner which can be used on most types of floor including natural stone.

Working in small sections, I used a spray gun to coat the floor with this cleaning solution, before leaving this to dwell for roughly 20 to 30 minutes. The solution was then scrubbed in to the tiles using a black buffing pad attached to a 17″ scrubbing machine. The resulting cleaning residue was then promptly removed using a wet-vac machine.

Cleaning the grout

After completing the tile cleaning and inspecting the floor to ensure all dirt and stains had been removed, I paid special attention to the grey grout lines. I opted to use a solution of Tile Doctor Grout Clean Up diluted with clean water. The ratio in this instance was roughly twenty per cent Grout Clean up to eighty per cent water.

Grout Clean Up is an acid-based product designed to penetrate beneath the surface of the grout to remove grout smears and mineral deposits, including rust. It is recommended for use on masonry surfaces and acid resistant stone such as Porcelain, Ceramic, Sandstone and Slate. Once both the tiles and the grout had been individually cleaned, I gave the floor a thorough rinse with clean water to remove any trace of product. All fluids were extracted using a wet vacuum.

Deep cleaning the entire Porcelain floor took some time but the was certainly worth the effort, the tiles now look so much cleaner and the grout a consistent shade of grey.

Sealing Flagstone Floor Tiles at a Farm Office

We work on a lot of residential tile installations but also cover commercial properties too, such as this new farm office which was in the process of being built in the market town of Driffield, East Yorkshire where a Flagstone tiled floor had been laid at the entrance. Driffield is known as the ‘Capital of the Yorkshire Wolds’ and lies near the source of the River Hull.

The farm office project was very big and, with the pressure on to complete it in time, the floor had been laid without being sealed first. As a result, the floor was getting dirty very easily, and was proving difficult to keep clean. It was clear that the Flagstone tiles would need to be cleaned and sealed, and I was called upon to get the job done.

Cleaning dirty Flagstone floor tiles

To clean the floor I first mixed a 50:50 solution of clean water and Tile Doctor Pro Clean. Pro Clean is a high-alkaline cleaner which is safe to use on a wide range of natural stone floors. The cleaning solution was worked in using a rotary machine fitted with a black buffing pad which proved an effective method, lifting off the dust and residue that had been left on the surface of the Flagstone tiles during the course of construction work.

The excess residue was extracted using a wet-vac machine. I then repeated the whole process over again several times in order to get the floor as clean as possible.

Sealing the Flagstone tiled floor

To seal the floor I used a combination of two different Tile Doctor sealers. Firstly, I applied a layer of Tile Doctor Colour Grow to the floor. This colour intensifying sealer is specially formulated to enhance the fantastic natural colours in the stone, while at the same time providing durable surface protection.

The floor was then finished off with a couple of coats of Tile Doctor Seal & Go. This added to the stain resistance of the floor, while also delivering a very nice subtle shine on the surface.

All signs of building work have been removed from the stone floor and it is now looking presentable ready for the opening of the new office, the combination sealer applied to the floor will also make sure it stays that way for some time to come.
