Badly Maintained Slate Tiles Rejuvenated in Gloucester

This Slate tiled floor in the hallway of a property in Gloucester had been laid 28 years ago, but during this time had received no proper maintenance. The property owner used to clean the tiles once a week using a steam cleaner to little effect.

In fact, we don’t normally recommend steam cleaning sealed surfaces as it will erode the sealer prematurely. After countless years of steam cleaning, I was confident that any traces of old sealer on this floor would be non-existent at this point.

This is, of course, a problem because a lack of sealer exposes the stone to ingrained dirt and stains. The effects of this are shown in the photos below: as you can see, the Slate had completely lost its lustre and naturally colourful patina.

I was asked by the property owner to provide this Slate tiled hallway with the restoration that was so long overdue, so I travelled to the house in Gloucester, a city situated near the Welsh border and between the Cotswolds and the Forest of Dean.

Cleaning a Dirty Slate Tiled Hallway

I started the restoration by mixing a strong solution of Tile Doctor Remove and Go combined with Tile Doctor NanoTech HBU. These two products serve different purposes. Remove and Go is a stripper designed to break down any traces of old sealer that might still have existed, as well as any paints and adhesive markings; NanoTech HBU is a potent cleaner which contains nano-sized cleaning particles that penetrate deep into the stone to get underneath tough dirt and stains to dissolve and lift them out.

This cleaning solution was spread over the floor and left to dwell for 30 minutes, before being scrubbed in using a black scrubbing pad fitted to a buffing machine. A thick black slurry resulted from this process and this needed to be removed using a wet vacuum.

Next, I repeated this cleaning process using Tile Doctor Pro Clean, our reliable alkaline cleaner, to provide a more thorough clean for the tiles and grout. The slurry was once again removed using a wet vacuum, before I then rinsed the whole floor with fresh water to remove any traces of chemicals.

When satisfied with outcome of the cleaning process, I left the floor to dry overnight.

Sealing a Slate Tiled Hallway

Upon arriving back at the property, the next day, I ran some quick moisture tests to check that the floor was dry. Thankfully, there were no damp issues and I was able to seal the tiles using four coats of Tile Doctor Seal and Go, leaving each coat to dry before applying the next.

Seal and Go is a water based sealer (so no smell as it dries) which adds durable stain resistance and a low-sheen finish that brings out the best in the slate.

The customer’s reaction to the outcome of the restoration was fantastic. She never expected the floor to turn out so beautifully and was very pleased.
