Our Limestone Cleaning Process
Specailists get started by putting on a Limestone floor cleaning chemical over the Limestone. We leave the cleaner to work for upto twenty minutes so it can emulsify the soil. They also use a scrubing machine to work the cleaning chemical into the floor.
After the scrubbing phase, they clear away the slurry and assess the state of the Limestone. They keep scrubbing and rinsing until it has released all of the soil it can. With polished and honed Limestone floors, one scrubbing and rinsing stage is generally enough to clean out the ingrained dirt. Having said that, with Tumbled Limestone tiles and Brushed Limestone floors, the cleaning may need to be repeated several times.
After scrubbing, there can still be soil trapped within the surface of Brushed and Tumbled Limestone, and in the grout.
If there is some ingrained dirt after scrubbing, we can use hot pressure rinsing apparatus. Hot pressurised rinsing forces hot water deep within the pores and holes in the Limestone and the grout, to access the soil that the floor scruber could not reach. It's frequently surprising how more dirt the pressure rinsing equipment takes out.
pressurised rinsing is almost certainly not ideal for very porous or soft Limestone, as it can leave a shadow effect with the cleaning.
Limestone Polishing
Limestone polishing is necessary once the initial shine has worn away from a polished Limestone through wear and other damage.
Limestone polishing commences with diamond honing tools to take off any surface defects and prepare the Limestone for diamond polishing.
Fine diamond tooling creates a honed or sheen finish. If you prefer a high , after polishing, we use Limestone polishing powders to give a polished shine.
Limestone Restoration
Limestone restoration starts by inspecting the floor for any issues. Usually the have of strong detergents and shoe traffic damages the surface on Limestone.
The result is a scratched, permeable finish with tiny, dirt-attracting holes. At these times, the original finish is taken off by grinding and also honing.
This technique is called restoraion. We use various Limestone floor restoration products such as; diamonds for grinding and also honing, epoxy fillers, grouts and also polishing creams to create a gloss shine.
Wear over older Limestone floors is a result of years, perhaps decades, of being walked over. Laminations in the tile can break up, tiles may crack, and the linestone subfloor might move.
This wear is also a reminder of your floor's historical past, so it is often better to welcome these flaws rather than disturb a vintage Limestone floor. Most of the time, these older floors are in listed heritage buildings and any work is strictly controlled via the Heritage authorities.

Sealing Limestone begins by assessing the type of Limestone plus the state of the sub-floor.
Sealing A Limestone Floor Without A Damp-Proof Membrane
Limestone has been a flooring for millenia. Buildings prior to the mid-1950s may have stone floors put straight onto well-rammed earth, a chalk base or lime mortar.
These types of floors want to permit the flow of moisture from the floor base, which has an effect on the selection of the Limestone sealer.
These types of floors should be sealed with a penetrating or impregnating sealer to maintain the movement of moisture.
Choosing A Sealer For Polished Limestone Tiles
To keep the natural look of polished Limestone, an impregnating sealer is normally applied. A polished Limestone needs less sealer than other finishes, so 1 or 2 costs of sealer usually sufficient. There isn't a lot of sealer a polished Limestone, therefore the sealer should really be topped up every year. Acid spills go through an impregnating sealer, leaving an etch mark. {This means that acid spills such as [xfield_acid-spills] will penetrate the impregnating sealer on your own Limestone floor, leaving a dull etch mark.} Strong coloured acid spills will etch and stain the Limestone.
Sealing Honed Limestone Floor Tiles
Limestone tiles with a honed finish will have a matt or sheen finish. Limestone is much more porous than a polished Limestone, but less porous than a tumbled Limestone. If you prefer a natural matt-look, an impregnating sealer retains the original finish. Much like polished Limestone, an impregnating sealer will not stop acid etching.
Honed Limestone tiles may have a film-forming or surface sealer. Just like name of the sealer implies, the sealer creates a protective film the top of the tiles. The protectoive film gives you extra protection against etch damage. The film acts Since a sacrificial wear layer, taking the damage from foot traffic rather than the surface of the tile . Because the protective sealer sits on the surface of the Limestone, we advise using a couple of coats of impregnating sealer first. An impregnating sealer helps protect the stone in areas where the surface film wears away.
A surface sealer can last for 2 to 4 years before it needs to be re-applied. We advise monitoring wear areas every six months to check for wear. If a region is displaying wear, dep-clean areas to take out any surface soil, then top the area up with a few layers of new sealer.
Using this technique, a floor protective sealer can last for many years, without suffering from an ugly build up of Limestone sealer on parts of the floor that don’t need more sealer.

How do you clean unsealed limestone?
Scrub the surface with a with a soft-bristled, non-metallic scrub brush ans a ph neutral Limestone cleaner. Rinse the stone with clean water and wipe clean with a microfiber cloth.
What causes black stains on limestone?
Chemicals from air pollution react with the stone to stain the stone. Also lichen develops to make black and white coloured spots.
Will bleach damage limestone?
Bleach should never be used on any limestone surface as it will damage the finish. If you accidentally spill bleach on Limestone, rinse with penty of clean water and dry.
Does limestone stain easily?
Limestone is more porous than other stone, and usually light in color, so is more easily stained.
