Moleanos Limestone is a very difficult stone to work with due to its’ porous chalky nature and needs to be sealed to prevent dirt accumulating in the stone. Without a sealer in place dirt builds up in the pores leaving it looking dirty and this is exacerbated in the case of White Moleanos Limestone which really shows up the dirt. I mention this as I was asked to visit a property in Leeds which had White Moleanos Limestone installed in the Kitchen and was now suffering this exact problem with the client unable to get it clean. The grout was also quite badly discoloured.
I visited the property to survey the floor and quote for renovating the stone. I ran some tests and could see that as suspected the original sealer had broken down leaving the stone vulnerable. Sealers typically last around three to five years depending on use, but this can be significantly reduced if a strong household cleaning product is used to clean the floor.
Without a seal in place dirt was able to get into the porous stone and once ingrained it can be very difficult to remove without the right products and equipment. I completed a demonstration clean on a small area to show how the floor should look and the result was immediate. Confident I was able to get the floor clean my client booked me in and we agreed a date to complete the work.
Cleaning White Moleanos Limestone Kitchen Tiles
To restore the appearance of the stone I used a set of Tile Doctors Burnishing Pads which are encrusted with industrial diamonds and are used to hone the stone, remove dirt and restore its appearance. This is a slow steady process and involves working through the different grades of burnishing pads from coarse to very fine. The pads are applied with a small amount of water to lubricate and the soil generated by the process is extracted with a wet vacuum afterwards, to keep the mess to a minimum.
All the grout was cleaned by hand using a strong dilution of Tile Doctor Pro-Clean which is scrubbed into the grout lines by hand with a stiff brush. For best results I leave it to dwell for ten minutes before scrubbing, this allows it more time to break down and lift the dirt from the cementitious grout lines.
After cleaning I left the floor to dry off fully overnight.
Sealing a Moleanos Limestone Tiled Kitchen Floor
The following morning, I returned to the property and checked the floor was dry using a moisture meter. This is always worth checking as applying a sealer to a damp floor can result in a patchy appearance.
I had discussed the effects of the different sealers suitable for use on Limestone and the client specified they were after a natural look that wasn’t over shiny. With this in mind I selected Tile Doctor Ultra Seal which is a penetrating sealer formulated to provide maximum stain protection and is especially recommended for use in kitchen areas. Ultra-seal doesn’t change the look of the stone which made it a nice match for the client’s needs, it’s also a good grout sealer and will ensure the grout looks cleaner for longer.
Three coats of Ultra-Seal where applied allowing each one to dry before applying the next. With the new sealer in place the stone is protected from ingrained dirt and would prove to be much easier to keep clean in future.
The client was very pleased with the finished result and before leaving I recommended, they maintain the floor using Tile Doctor Stone Soap which is designed for the cleaning of polished stone.
