Removing Sticky Coatings from Slate Floor Tiles

A recent customer of mine had a Slate tiled conservatory that had not been used in a long time since it had become covered in a sticky oil residue and couldn’t be walked over. I can’t go into detail as to how it became it this sate however suffice to say my customer had not been successful in removing it and having tried a number of products and suggestions had decided to call in their local Tile Doctor to remedy the situation.

The customer lives in Bicester just off Junction 9 of the M40 and famous for its Bicester Village outlet shopping centre, which has recently been expanded and is popular for containing discount retail outlets for several major designer clothing stores as well as restaurants and coffee shops.

Cleaning Conservatory Slate Tiles

I could see this was going to be a tricky job so to begin, I created a cocktail of cleaning products consisting of Tile Doctor NanoTech HBU and Tile Doctor Oxy-Gel. NanoTech HBU is one of our most powerful cleaners (HBU = Heavy Build-Up) as it uses Nano-sized particles to penetrate deep into the pores of the stone to release ingrained dirt. Oxy-Gel is an alkaline-based cleaner and degreaser, which helps to break down oily and sticky residues.

I applied this cleaning solution across the floor and left it to work its magic for about four hours. Next, I rinsed the floor with fresh water and extracted the soil using a wet vacuum before proceeding to clean the tiles again using a strong dilution of Tile Doctor Pro-Clean.

Once again, I rinsed away any remaining chemicals with fresh water, before giving the floor an acid wash using Tile Doctor Grout Clean-Up. Giving the stone and Acid Wash removes grout smears, mineral deposits and efflorescence and really gets the stone clean. After completing the cleaning process with another rinse, I left the floor to dry for a couple of days.

Sealing Conservatory Slate Tiles

On my return to the property 48 hours later, I treated the tiles to fresh sealant to protect them from stains and ingrained dirt for the long term. To do this, I used six coats of Tile Doctor Seal and Go, which works really well on Slate to provide a high-quality and highly aesthetic low-sheen finish.

The customer was very pleased with the transformation – not least because it meant she could use the conservatory again!
