Dri-Pod floor dryer

The single most important thing you need to do after having a new natural stone floor installed is to seal the tiles. The sealant acts as a barrier of protection for the stone against ingrained dirt, so without it the floor will become very difficult to keep clean.

This is the exact problem faced by my recent customer, who lives in the town of Thaxted in North Essex. Thaxted is a very historic place with over 1000 years of history and several fantastic medieval houses. The Slate kitchen tiles in the property had not been sealed after installation and, despite Slate being naturally durable and hard wearing, the tiles had quickly become dull and difficult to keep clean.

Despite valiant efforts at a DIY restoration, the customer required our professional assistance with deep cleaning and sealing the tiles to restore them back to their best condition.

Cleaning a Dirty Slate Tiled Floor

To begin the cleaning process, I applied Tile Doctor Remove and Go across the floor and scrubbed it in using a slow speed rotary machine fitted with a scrubbing pad. Remove and Go is a multi-purpose product: it strips away any old sealer, adhesive and paint stains, and draws out ingrained stains and removes heavy soil build-up. The resulting slurry was then removed using a wet-vac machine.

Next, I focused my attention on the dirty grout lines, treating them with a strong solution of Tile Doctor Pro-Clean which was then scrubbed in along the grout line using a stiff brush.

There was still evidence of some grout haze on the stone following installation some years back so the floor was then treated to an acid wash using Tile Doctor Grout Clean-up which is a concentrated phosphoric acid cleaner designed to life grout smears haze (smears).

Once done I pressure washed the floor using a specialised spinning tool which blasts the tiles and grout with water to remove ingrained dirt from the most difficult-to-reach areas in the stone. The water is subsequently vacuumed back into a holding tank in my van without causing any splashing or overspill.

Sealing a Slated Tiled Floor

The customer was keen for the restoration to be finished within the space of a single day, so I installed a few Dri-Pod floor dryers to get the floor dry and ready to be sealed in no time. We typically leave at least 24 hours for these types of floors to dry naturally, but in this scenario the floor dryers were able to remove any excess moisture.

To complete the restoration, I applied four coats of Tile Doctor Seal and Go Extra to the floor to seal it. This a special acrylic-based sealer that protects the stone and allows for moisture vapour transmission. The makes it ideal for situations in which no damp proof membrane has been installed.

The addition of the sealer gave the floor a beautiful lustre – as you can see from the photos below – and will make the floor much easier to keep clean in the future. After months of difficulty, the customer was over the moon that the floor had finally been restored to its peak condition.
