Our client contacted Tile Doctor as they were having problems cleaning their Slate tiled ensuite bathroom. We visited the property in nearby Stevenage, a London commuter town which is between Letchworth Garden City and Welwyn Garden City. The bathroom had been fitted some time ago, but due to the hard water in the area, there had been a large build up of limescale. The dark slate tiles showed this up even more.
My client had tried numerous household products on the tiles, but nothing was shifting the heavy build up. I discussed with them what Tile Doctor could do and completed a small demonstration. They were surprised how easily we were able to improve the tiles. We agreed a price and a timescale and booked the work in for a few weeks’ time.
Cleaning and Restoring a Slate Tiled Ensuite Bathroom
The ensuite shower required intensive cleaning to the shower walls and floor where excessive limescale was present so we got to work cleaning with Tile Doctor Oxy-Gel, this is a strong alkaline based cleaner and degreaser, it is a gel so it works well on vertical surfaces where a long dwell time is required to break down dirt, grime, soap scum, oil based products. We left the product on the surface for approximately 10 minutes, removing all previous sealers and dirt. The residue was rinsed off and followed this up with a second clean using Tile Doctor Grout Clean-Up.
Grout Clean-Up is an acidic product designed to remove mineral deposits however you need to be careful with some types of stone as it can etch the surface if used incorrectly. To apply the product was diluted with water in a spray bottle and sprayed on to the wall tiles where it was scrubbed in and then rinsed off. The process was then repeated on the floor rinsing down thoroughly afterwards with water.
Sealing a Slate Tiled Ensuite Bathroom
Once the slate was clean and dry we proceeded to cut out the existing silicone sealant which was equally stained and was beyond cleaning. This is a slow job and care needs to be taken not to scratch the tiles. It is important to ensure all the old silicone is removed so there is a nice clean surface to reapply the new. This also gave the shower area more time to dry out.
We tested with the moisture meter to ensure the shower area was fully dry and then applied the sealer. We chose to apply three coats of Tile Doctor Colour Grow, this is an impregnating sealer that works by occupying the pores in the stone, so dirt can’t become ingrained there, its also a colour enhancing sealer that provides durable protection. We applied the coats then lightly buffed off the excess with a soft cloth and allowed the slate to dry. The following day we returned to re-silicone all the edges and joints.
We recommended to the customer to use a mild solution of Tile Doctor Stone Soap as a maintenance cleaner for the slate. The client was very happy with the result and could see that cleaning with the appropriate product would ensure the ensuite bathroom continued to look good. The whole job took a day and a half to complete.
