These Slate kitchen floor tiles at a property in Oxford were in good physical condition, but had become dull over time due to heavy usage, and upon close inspection the grout was stained. The customer contacted me as she was keen to get the tiles back to looking their best. This would require a thorough clean and the application of a fresh sealer.
While Slate floor tiles are reputed to be hard wearing and damage resistant – and are therefore a popular choice for high traffic areas like kitchens – this does not exclude them from needing regular maintenance.
Cleaning a Dull Slate Tiled Kitchen Floor
To begin, I mixed a strong solution of Tile Doctor Pro Clean and water. Pro-Clean is a versatile cleaner that when used in a weak dilution can be used as a regular cleaner for most types of natural stone floor, including more sensitive stones such as Limestone and Marble.
The cleaning was then spread across the surface area of the floor, and left it to dwell for ten minutes to allow the solution to seep into the pores of the stone and lift the ingrained dirt to the surface. Pro-Clean in a strong dilution also functions as a stripping product, meaning it works to strip away any old and ineffectual sealer.
I then scrubbed the solution into the floor using a stiff scrubbing brush, paying particular attention to the grout in order to break down the visible staining. The tiles and grout lines came up really well during the cleaning process – this became clear once I had rinsed the floor and removed the residue using a wet vacuum.
Sealing a Slate Tiled Kitchen Floor
With the customer eager to have the job completed quickly, I installed portable room dryers and utilised a heat gun to dry the floor, allowing me to seal it on the same day.
Once I had ensured the floor was completely dry, I commenced the sealing process by firstly applying a coat of Tile Doctor Stone Oil, a product which is designed to bring out all of the natural dark shades in the Slate.
When this was dry, I applied a single coat of Tile Doctor Colour Grow. This is an impregnating sealer, meaning that it soaks into pores of the stone to provide durable protection from within against ingrained dirt and stains. Colour Grow also enhances the natural colours in the stone even further.
